Definitions

  • This invention pertains to the discovery that polypeptides that inhibit the CGRP/CGRP receptor interaction and/or antibodies and antibody fragments that specifically bind CGRP or to a CGRP receptor may be used to inhibit CGRP-induced photophobia when administered to a subject in need thereof.
  • Polypeptides that inhibit the CGRP/CGRP receptor interaction for use in the invention include by way of example antibodies and antibody fragments specific to CGRP or the CGRP receptor and fragments or variants of CGRP or the CGRP receptor that inhibit CGRP from interacting with CGRP receptors.
  • CGRP -receptor inhibitors e.g., antibodies and antibody fragments specific to CGRP or the CGRP receptor should be well suited for inhibiting the photophobia often associated with migraine and other headache conditions as well as for treating other conditions associated with photophobia.
  • these antibodies and antibody fragments may be used to prevent the onset of photophobia in subjects in need thereof such as individuals with a chronic history of photophobia, e.g., as a result of migraine (with or without aura), other headache condition, depression, agoraphobia or other conditions prone to photophobia if the antibodies are administered prophylactically.
  • the invention contemplates the use of these anti-CGRP antibodies and antibody fragments as a monotherapy or in therapeutic regimens with other active agents, e.g., analgesics, opioids, antidepressants or other actives dependent on the condition and the individual treated.
  • the invention further provides methods of screening CGRP -receptor inhibitors, e.g., anti-CGRP or anti-CGRP receptor antibodies and fragments thereof (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") or the CGRP receptor in specific animal models to determine the in vivo effects thereof, most especially their ability to antagonize the photophobic side effects of CGRP and to treat conditions involving photophobia including e.g., migraine.
  • CGRP Calcitonin Gene Related Peptide
  • Calcitonin Gene Related Peptide is produced as a multifunctional neuropeptide of 37 amino acids in length.
  • CGRP-alpha and CGRP- beta differ by three amino acids in humans, and are derived from different genes.
  • the CGRP family of peptides includes amylin, adrenomedullin, and calcitonin, although each has distinct receptors and biological activities. Doods, H., Curr. Op. Invest. Drugs, 2(9): 1261-78 (2001).
  • CGRP CGRP receptor
  • RAMP receptor-associated membrane protein
  • Migraines constitute a neurovascular disorder affecting approximately 10% of the adult population in the U.S., and are typically accompanied by intense headaches. Approximately 20-30% of migraine sufferers experience aura, comprising focal neurological phenomena that precede and/or accompany the event. CGRP is believe to play a prominent role in the development of migraines. For example, plasma concentrations of CGRP were identified elevated in jugular venous blood during the headache phase of migraines, to the exclusion of other neuropeptides.
  • triptans which are a family of tryptamine-based drugs, including sumatriptan and rizatriptan. Members of this family have an affinity for multiple serotonin receptors, including 5-HT IB , 5-HT ID , and 5- HT IF . Members of this family of drugs selectively constrict cerebral vessels, but also cause vasoconstrictive effects on coronary vessels. Durham, P.L., New Eng. J. Med., 350 (11): 1073-75 (2004). There is a theoretical risk of coronary spasm in patients with established heart disease following administration, and cardiac events after taking triptans may rarely occur. Noted to be contraindicated for patients with coronary vascular disease.
  • NSAIDs non-steroidal anti-inflammatory drugs
  • the administration of these treatments may occur at the cost of certain negative consequences.
  • NSAIDs have the potential to cause kidney failure, intestinal bleeding, and liver dysfunction.
  • Narcotics have the potential to cause nausea, vomiting, imparled mental functioning, and addiction. Therefore, it is desirable to identify alternative treatments for pain in order to avoid certain of these negative consequences.
  • CGRP is believed to play a role in a multitude of diseases and disorders, including but not limited to other headache conditions, and pain. Due to the perceived involvement of CGRP in these diseases and disorders, there remains a need in the art for compositions and methods useful for preventing or treating diseases and disorders associated with CGRP, while avoiding adverse side effects. There in particular remains a need in the art for compositions or methods that reduce or inhibit photophobia in diseases or disorders associated with CGRP, such as migraines, headaches, and pain.
  • Migraineurs typically develop worsening pain and migraine symptoms when exposed to light, a phenomenon known as photophobia.
  • Photophobia is also common in ocular disorders, such as ulceris and uveitis, and intracranial disorders, such as meningitis.
  • This pathway includes image-forming and non-image-forming data.
  • a new pathway (non-image-forming information) allows maintenance of normal circadian rhythms via the suprachiasmatic nucleus and is regulated by intrinsically photosensitive retinal ganglion cells (ipRGCs). These ipRGCs are independent of the rods and cones and contain melanopsin, a photopigment.
  • Photophobia also accompanies other less frequent but likewise disabling conditions, such as cluster headache and other trigeminal autonomic cephalalgias and blepharospasm.
  • the mechanisms underlying photophobia involve the trigeminal system. Photophobia in blind patients suggests contributions from a nonvisual pathway.
  • trigeminal autonomic cephalalgias a less common group of primary headache disorders, are characterized by unilateral trigeminal-mediated pain frequently associated with ipsilateral photophobia .
  • CGRP is elevated in external jugular venous blood during acute migraine pain, (Goadsby PJ, Edvinsson L, Ekman R . Vasoactive peptide release in the extracerebral circulation of humans during migraine headache. Ann Neurol 1990;28: 183-187) and triptans reduce elevated CGRP levels.
  • mice sensitized to CGRP demonstrate more light-aversive behavior when exposed to exogenous CGRP.
  • the administration of olcegepant, a CGRP receptor antagonist prevented photophobia in these mice. (See Recober A, Kaiser EA, Kuburas A, Russo AF. Induction of multiple photophobic behaviors in a transgenic mouse sensitized to CGRP. Neuropharmacology 2010;58: 156-165).
  • This invention relates to the discovery that polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction may be used to prevent or inhibit photophobia, especially CGR associated photophobia.
  • CGRP Calcitonin Gene Related Peptide
  • an anti-CGRP antibody identified as Ab3 infra that very effectively alleviates or prevents photophobia, especially the photophobic effects of CGRP.
  • Other prefered examples for use in the claimed therapies are Ab6 and AblO among others.
  • the invention relates to the use of polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, preferably anti-CGRP antibodies and anti-CGRP antibody fragments for treating or preventing photophobia.
  • polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, preferably anti-CGRP antibodies and anti-CGRP antibody fragments for treating or preventing photo
  • the invention embraces the treatment or prevention of any photophobia, and in particular includes treatment or prevention of photophobia associated with migraine, and other disorders associated with photophobia such as cluster headache and other trigeminal autonomic cephalalgias and blepharospasm, depression, bipolar disorders, agoraphobia, meningitis, and photophobias associated with eye related conditions, autism, chronic fatigue syndrome, menstrual migraines, and other photopbia-associated conditions.

  • the selectable marker allows that cell to survive and grow in a selective growth medium under conditions in which cells that do not receive that selectable marker gene cannot grow.
  • Selectable marker genes generally fall into several types, including positive selectable marker genes such as a gene that confers on a cell resistance to an antibiotic or other drug, temperature when two temperature sensitive ("ts") mutants are crossed or a ts mutant is transformed; negative selectable marker genes such as a biosynthetic gene that confers on a cell the ability to grow in a medium without a specific nutrient needed by all cells that do not have that biosynthetic gene, or a mutagenized biosynthetic gene that confers on a cell inability to grow by cells that do not have the wild type gene; and the like. Suitable markers include but are not limited to: ZEO; G418; LYS3; MET1; MET3a; ADE1; ADE3; URA3; and the like.
  • Expression Vector contain elements that facilitate manipulation for the expression of a foreign protein within the target host cell. Conveniently, manipulation of sequences and production of DNA for transformation is first performed in a bacterial host, e.g. E. coli, and usually vectors will include sequences to facilitate such manipulations, including a bacterial origin of replication and appropriate bacterial selection marker. Selection markers encode proteins necessary for the survival or growth of transformed host cells grown in a selective culture medium. Host cells not transformed with the vector containing the selection gene will not survive in the culture medium. Typical selection genes encode proteins that (a) confer resistance to antibiotics or other toxins, (b) complement auxotrophic deficiencies, or (c) supply critical nutrients not available from complex media.

  • DNA for a signal sequence is operably linked to DNA for a polypeptide if it is expressed as a preprotein that participates in the secretion of the polypeptide; a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the sequence.
  • "operably linked” means that the DNA sequences being linked are contiguous, and, in the case of a secretory leader, contiguous and in reading frame. However, enhancers do not have to be contiguous.
  • Linking is accomplished by ligation at convenient restriction sites or alternatively via a PCR/recombination method familiar to those skilled in the art (Gateway R Technology; Invitrogen, Carlsbad California). If such sites do not exist, the synthetic oligonucleotide adapters or linkers are used in accordance with conventional practice.
  • Promoters are untranslated sequences located upstream (5') to the start codon of a structural gene (generally within about 100 to 1000 bp) that control the transcription and translation of particular nucleic acid sequences to which they are operably linked. Such promoters fall into several classes: inducible, constitutive, and repressible promoters (that increase levels of transcription in response to absence of a repressor). Inducible promoters may initiate increased levels of transcription from DNA under their control in response to some change in culture conditions, e.g., the presence or absence of a nutrient or a change in temperature.

BACKGROUND OF THE INVENTION
Field of the Invention
[0003] This invention pertains to the discovery that polypeptides that inhibit the CGRP/CGRP receptor interaction and/or antibodies and antibody fragments that specifically bind CGRP or to a CGRP receptor may be used to inhibit CGRP-induced photophobia when administered to a subject in need thereof. Polypeptides that inhibit the CGRP/CGRP receptor interaction for use in the invention include by way of example antibodies and antibody fragments specific to CGRP or the CGRP receptor and fragments or variants of CGRP or the CGRP receptor that inhibit CGRP from interacting with CGRP receptors. As photophobia is an adverse side-effect often associated with many disorders including by way of example migraine with and without aura and other headache conditions (as well as other indications disclosed infra) t these CGRP -receptor inhibitors, e.g., antibodies and antibody fragments specific to CGRP or the CGRP receptor should be well suited for inhibiting the photophobia often associated with migraine and other headache conditions as well as for treating other conditions associated with photophobia. The results also suggest that these antibodies and antibody fragments may be used to prevent the onset of photophobia in subjects in need thereof such as individuals with a chronic history of photophobia, e.g., as a result of migraine (with or without aura), other headache condition, depression, agoraphobia or other conditions prone to photophobia if the antibodies are administered prophylactically. The invention contemplates the use of these anti-CGRP antibodies and antibody fragments as a monotherapy or in therapeutic regimens with other active agents, e.g., analgesics, opioids, antidepressants or other actives dependent on the condition and the individual treated.
[0004] The invention further provides methods of screening CGRP -receptor inhibitors, e.g., anti-CGRP or anti-CGRP receptor antibodies and fragments thereof (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") or the CGRP receptor in specific animal models to determine the in vivo effects thereof, most especially their ability to antagonize the photophobic side effects of CGRP and to treat conditions involving photophobia including e.g., migraine.
Description of Related Art
[0005] Calcitonin Gene Related Peptide (CGRP) is produced as a multifunctional neuropeptide of 37 amino acids in length. Two forms of CGRP, the CGRP-alpha and CGRP -beta forms, exist in humans and have similar activities. CGRP-alpha and CGRP- beta differ by three amino acids in humans, and are derived from different genes. The CGRP family of peptides includes amylin, adrenomedullin, and calcitonin, although each has distinct receptors and biological activities. Doods, H., Curr. Op. Invest. Drugs, 2(9): 1261-78 (2001).
[0006] CGRP is released from numerous tissues such as trigeminal nerves, which when activated release neuropeptides within the meninges, mediating neurogenic inflammation that is characterized by vasodilation, vessel leakage, and mast-cell degradation. Durham, P.L., New Eng. J. Med., 350 (l l): 1073-75 (2004). The biological effects of CGRP are mediated via the CGRP receptor (CGRP-R), which consists of a seven-transmembrane component, in conjunction with receptor-associated membrane protein (RAMP). CGRP-R further requires the activity of the receptor component protein (RCP), which is essential for an efficient coupling to adenylate cyclase through G proteins and the production of cAMP. Doods, H., Curr. Op. Invest. Drugs, 2(9): 1261-78 (2001).
[0007] Migraines constitute a neurovascular disorder affecting approximately 10% of the adult population in the U.S., and are typically accompanied by intense headaches. Approximately 20-30% of migraine sufferers experience aura, comprising focal neurological phenomena that precede and/or accompany the event. CGRP is believe to play a prominent role in the development of migraines. For example, plasma concentrations of CGRP were identified elevated in jugular venous blood during the headache phase of migraines, to the exclusion of other neuropeptides. Moreover, according to Arulmozhi et al, the following has been identified in migraine sufferers: (1) a strong correlation between plasma CGRP concentrations and migraines; (2) the infusion of CGRP produced a migraine-like headache; (3) baseline CGRP levels were elevated; and (4) changes in plasma CGRP levels during migraine attacks significantly correlated with headache intensity. Arulmozhi, D.K., et al., Vas. Pharma., 43: 176-187 (2005). In addition, in the Journal of the International Association for the Study of Pain PII:S0304- 3959(11)00313-7; doi:10.1016/j.pain.2011.04.033, published online 06 June 2011, Hou et al., reported that keratinocyte expression of calcitonin gene-related peptide β has implications for neuropathic and inflammatory pain mechanisms.
[0008] One effective treatment for migraines is the administration of triptans, which are a family of tryptamine-based drugs, including sumatriptan and rizatriptan. Members of this family have an affinity for multiple serotonin receptors, including 5-HTIB, 5-HTID, and 5- HTIF. Members of this family of drugs selectively constrict cerebral vessels, but also cause vasoconstrictive effects on coronary vessels. Durham, P.L., New Eng. J. Med., 350 (11): 1073-75 (2004). There is a theoretical risk of coronary spasm in patients with established heart disease following administration, and cardiac events after taking triptans may rarely occur. Noted to be contraindicated for patients with coronary vascular disease. [0009] Similarly, pain may often be addressed through the administration of certain narcotics or non-steroidal anti-inflammatory drugs (NSAIDs). However, the administration of these treatments may occur at the cost of certain negative consequences. NSAIDs have the potential to cause kidney failure, intestinal bleeding, and liver dysfunction. Narcotics have the potential to cause nausea, vomiting, imparled mental functioning, and addiction. Therefore, it is desirable to identify alternative treatments for pain in order to avoid certain of these negative consequences.
[00010] Aside from migraine, CGRP is believed to play a role in a multitude of diseases and disorders, including but not limited to other headache conditions, and pain. Due to the perceived involvement of CGRP in these diseases and disorders, there remains a need in the art for compositions and methods useful for preventing or treating diseases and disorders associated with CGRP, while avoiding adverse side effects. There in particular remains a need in the art for compositions or methods that reduce or inhibit photophobia in diseases or disorders associated with CGRP, such as migraines, headaches, and pain.
[00011] Migraineurs typically develop worsening pain and migraine symptoms when exposed to light, a phenomenon known as photophobia. Photophobia is also common in ocular disorders, such as iritis and uveitis, and intracranial disorders, such as meningitis. In the classic visual pathway, light activates rods and cones in the retina, which activate retinal ganglion cells that project via the optic nerve, to the lateral geniculate nucleus, superior colliculus, and then the visual cortex. This pathway includes image-forming and non-image-forming data. A new pathway (non-image-forming information) allows maintenance of normal circadian rhythms via the suprachiasmatic nucleus and is regulated by intrinsically photosensitive retinal ganglion cells (ipRGCs). These ipRGCs are independent of the rods and cones and contain melanopsin, a photopigment.
[00012] Noseda et al.(Noseda, R. et al. A neural mechanism for exacerbation of headache by light. Nat. Neurosci. 13, 239-245 (2010)) studied blind individuals who had migraine and correlated these findings with rat models involving tracing of ipRGC projections to areas in perception of pain from the dura. Of the blind patients with migraine, 6 had no light perception due to severe optic nerve damage or bilateral enucleation. These subjects experienced abnormal sleep patterns and poor pupillary light responses. Their migraines did not worsen with light exposure. In contrast, 14 blind subjects who were able to detect light despite minimal perception of images had normal sleep patterns and a normal pupillary light reflex. Despite widespread rod and cone degeneration, these patients had worsening migraine symptoms with light exposure during migraine attacks, suggesting that ipRGCs, and not rods and cones, are important in photophobia.
[00013] These retinal projections of non-image-forming brain areas project to the contralateral dorsocaudal region of the posterior thalamus, as demonstrated by anterograde tracing in the rat. ipRGC input to this area modulates dura-sensitive pain neurons, which also project to this region. Thalamic neurons, dually sensitive to dural pain and light input, project widely to multiple cortical regions, including the primary somatosensory cortex, the primary and secondary motor cortices, the parietal association cortex, and the primary and secondary visual cortices. These cortical projections may help explain other common migraine symptoms, in addition to photophobia, such as motor weakness or incoordination, visual disturbances, and poor concentration.
[00014] Photophobia also accompanies other less frequent but likewise disabling conditions, such as cluster headache and other trigeminal autonomic cephalalgias and blepharospasm. The mechanisms underlying photophobia involve the trigeminal system. Photophobia in blind patients suggests contributions from a nonvisual pathway. In addition, trigeminal autonomic cephalalgias, a less common group of primary headache disorders, are characterized by unilateral trigeminal-mediated pain frequently associated with ipsilateral photophobia .
[00015] Stimulation of trigeminal sensory neurons results in the release of neuropeptides (including substance P and calcitonin gene-related peptide, producing blood vessel dilation and mast cell, endothelial, and platelet activation (neurogenic inflammation), which leads to migraine. (Buzzi MG, Dimitriadou V, Theoharides TC, Moskowitz MA . 5- Hydroxytryptamine receptor agonists for the abortive treatment of vascular headaches block mast cell, endothelial and platelet activation within the rat dura mater after trigeminal stimulation. Brain Res 1992;583: 137-149). CGRP is elevated in external jugular venous blood during acute migraine pain, (Goadsby PJ, Edvinsson L, Ekman R . Vasoactive peptide release in the extracerebral circulation of humans during migraine headache. Ann Neurol 1990;28: 183-187) and triptans reduce elevated CGRP levels. In animal models, mice sensitized to CGRP demonstrate more light-aversive behavior when exposed to exogenous CGRP. The administration of olcegepant, a CGRP receptor antagonist, prevented photophobia in these mice. (See Recober A, Kaiser EA, Kuburas A, Russo AF. Induction of multiple photophobic behaviors in a transgenic mouse sensitized to CGRP. Neuropharmacology 2010;58: 156-165).
[00016] However, while the use of anti-CGRP or anti-CGRP receptor antibodies and fragments to treat migraine has been suggested, to the best of Applicant's knowledge there has been no report of any polypeptide CGRP antagonist or in particular an anti-CGRP or anti-CGRP receptor antibody or antibody fragment able to alleviate or prevent the photophobic side effects of CGRP in vivo. The development of novel polypeptides that act as inhibitors of the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies or anti-CGRP or anti-CGRP receptor antibody fragments would be beneficial for patients who either do not respond to current migraine therapeutics such as triptans or who cannot take or tolerate them because of their potential vasoconstrictive effects.
BRIEF SUMMARY OF THE INVENTION
[00017] This invention relates to the discovery that polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction may be used to prevent or inhibit photophobia, especially CGR associated photophobia. Herein we particularly exemplify an anti-CGRP antibody identified as Ab3 infra, that very effectively alleviates or prevents photophobia, especially the photophobic effects of CGRP. Other prefered examples for use in the claimed therapies are Ab6 and AblO among others.
[00018] Based thereon the invention relates to the use of polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) having binding specificity to human Calcitonin Gene Related Peptide (hereinafter "CGRP") as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, preferably anti-CGRP antibodies and anti-CGRP antibody fragments for treating or preventing photophobia. The invention embraces the treatment or prevention of any photophobia, and in particular includes treatment or prevention of photophobia associated with migraine, and other disorders associated with photophobia such as cluster headache and other trigeminal autonomic cephalalgias and blepharospasm, depression, bipolar disorders, agoraphobia, meningitis, and photophobias associated with eye related conditions, autism, chronic fatigue syndrome, menstrual migraines, and other photopbia-associated conditions.
[00019] This invention also pertains to methods of screening polypeptides which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor binding antibody fragments (including Fab fragments) having binding specificity to human CGRP as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, in specific photophobia animal models, e.g., the nestin/fiRAMPl rodent model disclosed infra, to determine the in vivo effects thereof, especially the ability of these polypeptides to inhibit the CGRP/CGRP receptor interaction in vivo and thereby antagonize the adverse in vivo side effects of CGRP including photophobia and to treat CGRP conditions involving CGRP associated photophobia including migraine and other disorders associated with photophobia such as cluster headache and other trigeminal autonomic cephalalgias and blepharospasm, depression, bipolar disorders, and other photophobia-associated conditions identified herein.
[00020] Also the invention specifically involves a method of assessing the potential in vivo efficacy of a candidate polypeptide which inhibit the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti- CGRP receptor antibody fragments (including Fab fragments) having binding specificity to CGRP as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, preferably an anti-CGRP or anti-CGRP receptor antibody or antibody fragment comprising determining whether the polypeptide, e.g., an antibody, inhibits light aversive behavior in a transgenic rodent which exhibits photoaversion when administered CGRP compared to the photoaversive behavior of the rodent administered CGRP in the absence of the candidateCGRP/CGRP receptor inhibitor polypeptide.
[00021] Also, the invention involves a method of assessing the potential in vivo efficacy of a candidate polypeptide which inhibit the CGRP/CGRP receptor interaction such as anti- CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti-CGRP receptor antibody fragments (including Fab fragments) as well as fragments of CGRP and the CGRP receptor that inhibit the CGRP/CGRP receptor interaction, preferably an anti-CGRP antibody or anti-CGRP receptor antibody or antibody fragment to treat a neurological condition or other condition characterized by increased CGRP levels that result in photophobia.
[00022] Further, the invention specifically involves a method of assessing the potential in vivo efficacy of a candidate polypeptide which inhibits the CGRP/CGRP receptor interaction such as anti-CGRP or anti-CGRP receptor antibodies and anti-CGRP or anti- CGRP receptor antibody fragments as well as fragments or variants of CGRP species and CGRP receptors that inhibit the CGRP/CGRP receptor interaction, preferably anti-CGRP or anti-CGRP receptor antibodies or antibody fragments to treat or prevent photophobia in migraine or chronic migraine, menstrual or menopausal or other hormonal associated migraines, cluster headaches or pain disorder associated with headache.
[00023] Still further, the invention involves a method of determining a suitable therapeutic dosage or dosage regimen of the candidate polypeptide CGRP/CGRP receptor inhibitor, e.g., anti-CGRP or anti-CGRP receptor antibody or antibody fragment in humans based on the effects of said polypeptide, e.g., an antibody or antibody fragment in a light aversive behavioral Nestin/hRAMPl rodent animal model described in detail infra.
[00024] Further the invention relates to methods of assessing based on results in a rodent CGRP (Nestin/hRAMPl animal model) a suitable therapeutic dosage or dosage regimen of the candidate polypeptide, e.g., an anti-CGRP or anti-CGRP receptor antibody or antibody fragment in humans.

It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention which will be limited only by the appended claims. As used herein the singular forms "a", "and", and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a cell" includes a plurality of such cells and reference to "the protein" includes reference to one or more proteins and equivalents thereof known to those skilled in the art, and so forth. All technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs unless clearly indicated otherwise.
[0059] Calcitonin Gene Related Peptide (CGRP): As used herein, CGRP encompasses not only the following Homo sapiens CGRP-alpha and Homo sapiens CGRP -beta amino acid sequences available from American Peptides (Sunnyvale CA) and Bachem (Torrance, CA):
CGRP-alpha: ACDTATCVTHRLAGLLSRSGGVVKNNFVPTNVGSKAF-NH2 (SEQ ID NO: 281), wherein the N-terminal phenylalanine is amidated;
CGRP-beta: ACNTATCVTHRLAGLLSRSGGMVKSNFVPTNVGSKAF-NH2 (SEQ ID NO: 282), wherein the N-terminal phenylalanine is amidated; but also any membrane- bound forms of these CGRP amino acid sequences, as well as mutants (mutiens), splice variants, isoforms, orthologues, homologues and variants of this sequence. In particular CGRP heein encompases rodent (rat or mouse) CGRP as well as CGRP from other mammals.
[0060] "CGRP receptor" or "CGRP-R" refers to the receptor binding partner of CGRP, preferably the human CGRP receptor, but encompassing other species CGRP-R's, especially rodent (rat or mouse), non-human primate and other mammalian CGRP-R's.
[0061] "CGRP/CGRP receptor inhibitor" herein refers to any polypeptide that inhibits the interaction of CGRP and CGRP receptors, e.g., anti-CGRP or anti-CGRP-R antibodies or antibody fragments and fragments of CGRP or CGRP-R polypeptides. Preferably these inhibitors will inhibit this interaction in vitro and in vivo and will inhibit the adverse side effects of CGRP including photoaversion or photophobia.
[0062] "Photophobia" herein refers to a symptom of abnormal intolerance to visual perception of light, sometimes additionally defined by abnormal or irrational fear of light, or by presence of actual physical photosensitivity of the eyes. In the present invention photophobia includes in particular light aversion associated with migraine, cluster headaches and other neurological causes of light aversive behavior that may trigger a migraine or cluster headache. Patients may develop photophobia as a result of several different medical conditions, related to the eye or the nervous system. Photophobia can be caused by an increased response to light starting at any step in the visual system such as: (i) too much light entering the eye, (ii) too much light can enter the eye if it is damaged, such as with corneal abrasion and retinal damage, or if a pupil(s) is unable to normally constrict (seen with damage to the oculomotor nerve, (iii) overstimulation of the photoreceptors in the retina, (iv) excessive electric impulses to the optic nerve, and (v) excessive response in the central nervous system.
[0063] Common causes of photophobia include migraine headaches, cataracts, or severe ophthalmologic diseases such as uveitis or corneal abrasion. A more extensive list of disorders associated with photophobia includes eye related causes such as Achromatopsia, Aniridia, Anticholinergic drugs may cause photophobia by paralyzing the iris sphincter muscle, Aphakia (absence of the lens of the eye), Buphthalmos (abnormally narrow angle between the cornea and iris), Cataracts, Cone dystrophy, Congenital abnormalities of the eye, Viral conjunctivitis ("pink eye") Corneal abrasion, Corneal dystrophy, Corneal ulcer, disruption of the corneal epithelium, such as that caused by a corneal foreign body or keratitis, Ectopia lentis, Endophthalmitis, Eye trauma caused by disease, injury, or infection such as chalazion, episcleritis, glaucoma, keratoconus, or optic nerve hypoplasia, Hydrophthalmos, or congenital glaucoma Iritis, Optic neuritis, Pigment dispersion syndrom, Pupillary dilation (naturally or chemically induced), Retinal detachment, Scarring of the cornea or sclera and Uveitis.
[0064] In addition photophobia has nervous-system-related or urological causes including: Autism spectrum disorders, Chiari malformation, Dyslexia, Encephalitis including Myalgic encephalomyelitis aka Chronic fatigue syndrome, Meningitis, Subarachnoid haemorrhage, Tumor of the posterior cranial fossa, as well as other causes such as Ankylosing spondylitis, Albinism, Ariboflavinosis, Benzodiazepines (long term use of or withdrawal from benzodiazepines), Chemotherapy, Chikungunya, Cystinosis, Ehlers- Danlos syndrome, Hangover, Influenza, Infectious Mononucleosis, Magnesium deficiency, Mercury poisoning, Migraine, Rabies, and Tyrosinemia type II, also known as "Richner- Hanhart syndrome". Additionally it is known that photophobia is elevated in depression, bipolar disorder and agoraphobia.
[0065] "Migraine" from the Greek words hemi, meaning half, and kranion, meaning skull) is a debilitating condition characterized by moderate to severe headaches, and nausea. It is about three times more common in women than in men. The typical migraine headache is unilateral (affecting one half of the head) and pulsating in nature and lasting from 4 to 72 hours; symptoms include nausea, vomiting, photophobia (increased sensitivity to light), phonophobia (increased sensitivity to sound); the symptoms are generally aggravated by routine activity. Approximately one-third of people who suffer from migraine headaches perceive an aura— unusual visual, olfactory, or other sensory experiences that are a sign that the migraine will soon occur. Initial treatment of migraine headaches typically is with analgesics for the headache, an antiemetic for the nausea, and the avoidance of triggering conditions. Studies of twins indicate a 60- to 65-percent genetic influence upon their propensity to develop migraine headaches. Moreover, fluctuating hormone levels indicate a migraine relation: 75 percent of adult patients are women, although migraine affects approximately equal numbers of prepubescent boys and girls; propensity to migraine headache is known to disappear during pregnancy, although in some women migraines may become more frequent during pregnancy.
[0066] "Effective treatment or prevention of photophobia" herein refers to inhibiting light aversive behavior or photophobia or inhibiting the onset of light aversive behavior or photophobia in a subject in need thereof, e.g., a subject having an active migraine attack or cluster headache or a subject prone to migraine or cluster headaches, or one of the other photophobia-asociated disorders identified herein after administration of an effective amount of an CGRP/CGRP receptor inhibitor polypeptide according to the invention, e.g., an anti-CGRP antibody or antibody fragment according to the invention. The treatment may be effected as a monotherapy or in association with another active agent such as Topirimate or dihydroergotamine by way of example.
[0067] Mating competent yeast species: In the present invention this is intended to broadly encompass any diploid or tetraploid yeast which can be grown in culture. Such species of yeast may exist in a haploid, diploid, or other polyploid form. The cells of a given ploidy may, under appropriate conditions, proliferate for an indefinite number of generations in that form. Diploid cells can also sporulate to form haploid cells. Sequential mating can result in tetraploid strains through further mating or fusion of diploid strains. The present invention contemplates the use of haploid yeast, as well as diploid or other polyploid yeast cells produced, for example, by mating or spheroplast fusion.
[0068] In one embodiment of the invention, the mating competent yeast is a member of the Saccharomycetaceae family, which includes the genera Arxiozyma; Ascobotryozyma; Citeromyces; Debaryomyces; Dekkera; Eremothecium; Issatchenkia; Kazachstania; Kluyveromyces; Kodamaea; Lodderomyces; Pachysolen; Pichia; Saccharomyces; Saturnispora; Tetrapisispora; Torulaspora; Williopsis; and Zygosaccharomyces. Other types of yeast potentially useful in the invention include Yarrowia; Rhodosporidium; Candida; Hansenula; Filobasium; Sporidiobolus; Bullera; Leucosporidium and Filobasidella.
[0069] In a preferred embodiment of the invention, the mating competent yeast is a member of the genus Pichia. In a further preferred embodiment of the invention, the mating competent yeast of the genus Pichia is one of the following species: Pichia pastoris, Pichia methanolica, and Hansenula polymorpha (Pichia angusta). In a particularly preferred embodiment of the invention, the mating competent yeast of the genus Pichia is the species Pichia pastoris.
[0070] Haploid Yeast Cell: A cell having a single copy of each gene of its normal genomic (chromosomal) complement.
[0071] Polyploid Yeast Cell: A cell having more than one copy of its normal genomic (chromosomal) complement.
[0072] Diploid Yeast Cell: A cell having two copies (alleles) of essentially every gene of its normal genomic complement, typically formed by the process of fusion (mating) of two haploid cells.
[0073] Tetraploid Yeast Cell: A cell having four copies (alleles) of essentially every gene of its normal genomic complement, typically formed by the process of fusion (mating) of two haploid cells. Tetraploids may carry two, three, four or more different expression cassettes. Such tetraploids might be obtained in S. cerevisiae by selective mating homozygotic heterothallic a/a and alpha/alpha diploids and in Pichia by sequential mating of haploids to obtain auxotrophic diploids. For example, a [met his] haploid can be mated with [ade his] haploid to obtain diploid [his]; and a [met arg] haploid can be mated with [ade arg] haploid to obtain diploid [arg]; then the diploid [his] x diploid [arg] to obtain a tetraploid prototroph. It will be understood by those of skill in the art that reference to the benefits and uses of diploid cells may also apply to tetraploid cells.
[0100] Yeast Mating: The process by which two haploid yeast cells naturally fuse to form one diploid yeast cell.
[0101] Meiosis: The process by which a diploid yeast cell undergoes reductive division to form four haploid spore products. Each spore may then germinate and form a haploid vegetatively growing cell line.
[0102] Selectable Marker: A selectable marker is a gene or gene fragment that confers a growth phenotype (physical growth characteristic) on a cell receiving that gene as, for example through a transformation event. The selectable marker allows that cell to survive and grow in a selective growth medium under conditions in which cells that do not receive that selectable marker gene cannot grow. Selectable marker genes generally fall into several types, including positive selectable marker genes such as a gene that confers on a cell resistance to an antibiotic or other drug, temperature when two temperature sensitive ("ts") mutants are crossed or a ts mutant is transformed; negative selectable marker genes such as a biosynthetic gene that confers on a cell the ability to grow in a medium without a specific nutrient needed by all cells that do not have that biosynthetic gene, or a mutagenized biosynthetic gene that confers on a cell inability to grow by cells that do not have the wild type gene; and the like. Suitable markers include but are not limited to: ZEO; G418; LYS3; MET1; MET3a; ADE1; ADE3; URA3; and the like.
[0103] Expression Vector. These DNA vectors contain elements that facilitate manipulation for the expression of a foreign protein within the target host cell. Conveniently, manipulation of sequences and production of DNA for transformation is first performed in a bacterial host, e.g. E. coli, and usually vectors will include sequences to facilitate such manipulations, including a bacterial origin of replication and appropriate bacterial selection marker. Selection markers encode proteins necessary for the survival or growth of transformed host cells grown in a selective culture medium. Host cells not transformed with the vector containing the selection gene will not survive in the culture medium. Typical selection genes encode proteins that (a) confer resistance to antibiotics or other toxins, (b) complement auxotrophic deficiencies, or (c) supply critical nutrients not available from complex media. Exemplary vectors and methods for transformation of yeast are described, for example, in Burke, D., Dawson, D., & Stearns, T. (2000). Methods in yeast genetics: a Cold Spring Harbor Laboratory course manual. Plainview, N.Y.: Cold Spring Harbor Laboratory Press.
[0104] Expression vectors for use in the methods of the invention will further include yeast specific sequences, including a selectable auxotrophic or drug marker for identifying transformed yeast strains. A drug marker may further be used to amplify copy number of the vector in a yeast host cell.
[0105] The polypeptide coding sequence of interest is operably linked to transcriptional and translational regulatory sequences that provide for expression of the polypeptide in yeast cells. These vector components may include, but are not limited to, one or more of the following: an enhancer element, a promoter, and a transcription termination sequence. Sequences for the secretion of the polypeptide may also be included, e.g. a signal sequence, and the like. A yeast origin of replication is optional, as expression vectors are often integrated into the yeast genome. In one embodiment of the invention, the polypeptide of interest is operably linked, or fused, to sequences providing for optimized secretion of the polypeptide from yeast diploid cells.
[0106] Nucleic acids are "operably linked" when placed into a functional relationship with another nucleic acid sequence. For example, DNA for a signal sequence is operably linked to DNA for a polypeptide if it is expressed as a preprotein that participates in the secretion of the polypeptide; a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the sequence. Generally, "operably linked" means that the DNA sequences being linked are contiguous, and, in the case of a secretory leader, contiguous and in reading frame. However, enhancers do not have to be contiguous. Linking is accomplished by ligation at convenient restriction sites or alternatively via a PCR/recombination method familiar to those skilled in the art (GatewayR Technology; Invitrogen, Carlsbad California). If such sites do not exist, the synthetic oligonucleotide adapters or linkers are used in accordance with conventional practice.
[0107] Promoters are untranslated sequences located upstream (5') to the start codon of a structural gene (generally within about 100 to 1000 bp) that control the transcription and translation of particular nucleic acid sequences to which they are operably linked. Such promoters fall into several classes: inducible, constitutive, and repressible promoters (that increase levels of transcription in response to absence of a repressor). Inducible promoters may initiate increased levels of transcription from DNA under their control in response to some change in culture conditions, e.g., the presence or absence of a nutrient or a change in temperature.
[0108] The yeast promoter fragment may also serve as the site for homologous recombination and integration of the expression vector into the same site in the yeast genome; alternatively a selectable marker is used as the site for homologous recombination. Pichia transformation is described in Cregg et al. (1985) Mol. Cell. Biol. 5:3376-3385. [0109] Examples of suitable promoters from Pichia include the AOX1 and promoter (Cregg et al. (1989) Mol. Cell. Biol. 9: 1316-1323); ICL1 promoter (Menendez et al. (2003) Yeast 20(13): 1097-108); glyceraldehyde-3 -phosphate dehydrogenase promoter (GAP) (Waterham et al. (1997) Gene 186(l):37-44); and FLD1 promoter (Shen et al. (1998) Gene 216(1):93-102). The GAP promoter is a strong constitutive promoter and the AOX and FLD1 promoters are inducible.
[0110] Other yeast promoters include ADH1, alcohol dehydrogenase II, GAL4, PH03, PH05, Pyk, and chimeric promoters derived therefrom. Additionally, non-yeast promoters may be used in the invention such as mammalian, insect, plant, reptile, amphibian, viral, and avian promoters. Most typically the promoter will comprise a mammalian promoter (potentially endogenous to the expressed genes) or will comprise a yeast or viral promoter that provides for efficient transcription in yeast systems.
[0111] The polypeptides of interest may be produced recombinantly not only directly, but also as a fusion polypeptide with a heterologous polypeptide, e.g. a signal sequence or other polypeptide having a specific cleavage site at the N-terminus of the mature protein or polypeptide. In general, the signal sequence may be a component of the vector, or it may be a part of the polypeptide coding sequence that is inserted into the vector. The heterologous signal sequence selected preferably is one that is recognized and processed through one of the standard pathways available within the host cell. The S. cerevisiae alpha factor pre-pro signal has proven effective in the secretion of a variety of recombinant proteins from P. pastoris. Other yeast signal sequences include the alpha mating factor signal sequence, the invertase signal sequence, and signal sequences derived from other secreted yeast polypeptides. Additionally, these signal peptide sequences may be engineered to provide for enhanced secretion in diploid yeast expression systems. Other secretion signals of interest also include mammalian signal sequences, which may be heterologous to the protein being secreted, or may be a native sequence for the protein being secreted. Signal sequences include pre-peptide sequences, and in some instances may include propeptide sequences. Many such signal sequences are known in the art, including the signal sequences found on immunoglobulin chains, e.g., K28 preprotoxin sequence, PHA-E, FACE, human MCP-1, human serum albumin signal sequences, human Ig heavy chain, human Ig light chain, and the like. For example, see Hashimoto et. al. Protein Eng 11(2) 75 (1998); and Kobayashi et. al. Therapeutic Apheresis 2(4) 257 (1998).
[0112] Transcription may be increased by inserting a transcriptional activator sequence into the vector. These activators are cis-acting elements of DNA, usually about from 10 to 300 bp, which act on a promoter to increase its transcription. Transcriptional enhancers are relatively orientation and position independent, having been found 5' and 3' to the transcription unit, within an intron, as well as within the coding sequence itself. The enhancer may be spliced into the expression vector at a position 5' or 3' to the coding sequence, but is preferably located at a site 5' from the promoter.
[0113] Expression vectors used in eukaryotic host cells may also contain sequences necessary for the termination of transcription and for stabilizing the mRNA. Such sequences are commonly available from 3' to the translation termination codon, in untranslated regions of eukaryotic or viral DNAs or cDNAs. These regions contain nucleotide segments transcribed as polyadenylated fragments in the untranslated portion of the mRNA.
[0114] Construction of suitable vectors containing one or more of the above-listed components employs standard ligation techniques or PCR/recombination methods. Isolated plasmids or DNA fragments are cleaved, tailored, and re-ligated in the form desired to generate the plasmids required or via recombination methods. For analysis to confirm correct sequences in plasmids constructed, the ligation mixtures are used to transform host cells, and successful transformants selected by antibiotic resistance (e.g. ampicillin or Zeocin) where appropriate. Plasmids from the transformants are prepared, analyzed by restriction endonuclease digestion and/or sequenced.
[0115] As an alternative to restriction and ligation of fragments, recombination methods based on att sites and recombination enzymes may be used to insert DNA sequences into a vector. Such methods are described, for example, by Landy (1989) Ann.Rev.Biochem. 55:913-949; and are known to those of skill in the art. Such methods utilize intermolecular DNA recombination that is mediated by a mixture of lambda and E.coli -encoded recombination proteins. Recombination occurs between specific attachment {att) sites on the interacting DNA molecules. For a description of att sites see Weisberg and Landy (1983) Site-Specific Recombination in Phage Lambda, in Lambda II, Weisberg, ed.(Cold Spring Harbor, NY:Cold Spring Harbor Press), pp. 211-250. The DNA segments flanking the recombination sites are switched, such that after recombination, the att sites are hybrid sequences comprised of sequences donated by each parental vector. The recombination can occur between DNAs of any topology.
[0116] Att sites may be introduced into a sequence of interest by ligating the sequence of interest into an appropriate vector; generating a PCR product containing att B sites through the use of specific primers; generating a cDNA library cloned into an appropriate vector containing att sites; and the like.
[0117] Folding, as used herein, refers to the three-dimensional structure of polypeptides and proteins, where interactions between amino acid residues act to stabilize the structure. While non-covalent interactions are important in determining structure, usually the proteins of interest will have intra- and/or intermolecular covalent disulfide bonds formed by two cysteine residues. For naturally occurring proteins and polypeptides or derivatives and variants thereof, the proper folding is typically the arrangement that results in optimal biological activity, and can conveniently be monitored by assays for activity, e.g. ligand binding, enzymatic activity, etc.
[0118] In some instances, for example where the desired product is of synthetic origin, assays based on biological activity will be less meaningful. The proper folding of such molecules may be determined on the basis of physical properties, energetic considerations, modeling studies, and the like.
[0119] The expression host may be further modified by the introduction of sequences encoding one or more enzymes that enhance folding and disulfide bond formation, i.e. foldases, chaperonins, etc. Such sequences may be constitutively or inducibly expressed in the yeast host cell, using vectors, markers, etc. as known in the art. Preferably the sequences, including transcriptional regulatory elements sufficient for the desired pattern of expression, are stably integrated in the yeast genome through a targeted methodology.
[0120] For example, the eukaryotic PDI is not only an efficient catalyst of protein cysteine oxidation and disulfide bond isomerization, but also exhibits chaperone activity. Co-expression of PDI can facilitate the production of active proteins having multiple disulfide bonds. Also of interest is the expression of BIP (immunoglobulin heavy chain binding protein); cyclophilin; and the like. In one embodiment of the invention, each of the haploid parental strains expresses a distinct folding enzyme, e.g. one strain may express BIP, and the other strain may express PDI or combinations thereof.
[0121] The terms "desired protein" or "desired antibody" are used interchangeably and refer generally to a parent antibody specific to a target, i.e., CGRP or CGRP receptor or a chimeric or humanized antibody or a binding portion thereof derived therefrom as described herein. The term "antibody" is intended to include any polypeptide chain- containing molecular structure with a specific shape that fits to and recognizes an epitope, where one or more non-covalent binding interactions stabilize the complex between the molecular structure and the epitope. The archetypal antibody molecule is the immunoglobulin, and all types of immunoglobulins, IgG, IgM, IgA, IgE, IgD, etc., from all sources, e.g. human, rodent, rabbit, cow, sheep, pig, dog, other mammals, chicken, other avians, etc., are considered to be "antibodies." A preferred source for producing antibodies useful as starting material according to the invention is rabbits. Numerous antibody coding sequences have been described; and others may be raised by methods well-known in the art. Examples thereof include chimeric antibodies, human antibodies and other non-human mammalian antibodies, humanized antibodies, single chain antibodies (such as scFvs), camelbodies, nanobodies, IgNAR (single-chain antibodies derived from sharks), small- modular immunopharmaceuticals (SMIPs), and antibody fragments such as Fabs, Fab', F(ab')2 and the like. See Streltsov VA, et al., Structure of a shark IgNAR antibody variable domain and modeling of an early-developmental isotype, Protein Sci. 2005 Nov;14(l l):2901-9. Epub 2005 Sep 30; Greenberg AS, et al, A new antigen receptor gene family that undergoes rearrangement and extensive somatic diversification in sharks, Nature. 1995 Mar 9;374(6518): 168-73; Nuttall SD, et al, Isolation of the new antigen receptor from wobbegong sharks, and use as a scaffold for the display of protein loop libraries, Mol Immunol. 2001 Aug;38(4):313-26; Hamers-Casterman C, et al., Naturally occurring antibodies devoid of light chains, Nature. 1993 Jun 3;363(6428):446-8; Gill DS, et al, Biopharmaceutical drug discovery using novel protein scaffolds, Curr Opin Biotechnol. 2006 Dec;17(6):653-8. Epub 2006 Oct 19. [0122] For example, antibodies or antigen binding fragments may be produced by genetic engineering. In this technique, as with other methods, antibody-producing cells are sensitized to the desired antigen or immunogen. The messenger R A isolated from antibody producing cells is used as a template to make cDNA using PCR amplification. A library of vectors, each containing one heavy chain gene and one light chain gene retaining the initial antigen specificity, is produced by insertion of appropriate sections of the amplified immunoglobulin cDNA into the expression vectors. A combinatorial library is constructed by combining the heavy chain gene library with the light chain gene library. This results in a library of clones which co-express a heavy and light chain (resembling the Fab fragment or antigen binding fragment of an antibody molecule). The vectors that carry these genes are co-transfected into a host cell. When antibody gene synthesis is induced in the transfected host, the heavy and light chain proteins self-assemble to produce active antibodies that can be detected by screening with the antigen or immunogen.
[0123] Antibody coding sequences of interest include those encoded by native sequences, as well as nucleic acids that, by virtue of the degeneracy of the genetic code, are not identical in sequence to the disclosed nucleic acids, and variants thereof. Variant polypeptides can include amino acid (aa) substitutions, additions or deletions. The amino acid substitutions can be conservative amino acid substitutions or substitutions to eliminate non-essential amino acids, such as to alter a glycosylation site, or to minimize misfolding by substitution or deletion of one or more cysteine residues that are not necessary for function. Variants can be designed so as to retain or have enhanced biological activity of a particular region of the protein (e.g., a functional domain, catalytic amino acid residues, etc). Variants also include fragments of the polypeptides disclosed herein, particularly biologically active fragments and/or fragments corresponding to functional domains. Techniques for in vitro mutagenesis of cloned genes are known. Also included in the subject invention are polypeptides that have been modified using ordinary molecular biological techniques so as to improve their resistance to proteolytic degradation or to optimize solubility properties or to render them more suitable as a therapeutic agent.
[0124] Chimeric antibodies may be made by recombinant means by combining the variable light and heavy chain regions (VL and VH), obtained from antibody producing cells of one species with the constant light and heavy chain regions from another. Typically chimeric antibodies utilize rodent or rabbit variable regions and human constant regions, in order to produce an antibody with predominantly human domains. The production of such chimeric antibodies is well known in the art, and may be achieved by standard means (as described, e.g., in U.S. Patent No. 5,624,659, incorporated herein by reference in its entirety). It is further contemplated that the human constant regions of chimeric antibodies of the invention may be selected from IgGl, IgG2, IgG3, and IgG4 constant regions.
[0125] Humanized antibodies are engineered to contain even more human-like immunoglobulin domains, and incorporate only the complementarity-determining regions of the animal-derived antibody. This is accomplished by carefully examining the sequence of the hyper-variable loops of the variable regions of the monoclonal antibody, and fitting them to the structure of the human antibody chains. Although facially complex, the process is straightforward in practice. See, e.g., U.S. Patent No. 6,187,287, incorporated fully herein by reference.
[0126] In addition to entire immunoglobulins (or their recombinant counterparts), immunoglobulin fragments comprising the epitope binding site (e.g., Fab', F(ab')2, or other fragments) may be synthesized. "Fragment," or minimal immunoglobulins may be designed utilizing recombinant immunoglobulin techniques. For instance "Fv" immunoglobulins for use in the present invention may be produced by synthesizing a fused variable light chain region and a variable heavy chain region. Combinations of antibodies are also of interest, e.g. diabodies, which comprise two distinct Fv specificities. In another embodiment of the invention, SMIPs (small molecule immunopharmaceuticals), camelbodies, nanobodies, and IgNAR are encompassed by immunoglobulin fragments.
[0127] Immunoglobulins and fragments thereof may be modified post-translationally, e.g. to add effector moieties such as chemical linkers, detectable moieties, such as fluorescent dyes, enzymes, toxins, substrates, bioluminescent materials, radioactive materials, chemiluminescent moieties and the like, or specific binding moieties, such as streptavidin, avidin, or biotin, and the like may be utilized in the methods and compositions of the present invention. Examples of additional effector molecules are provided infra. [0128] A polynucleotide sequence "corresponds" to a polypeptide sequence if translation of the polynucleotide sequence in accordance with the genetic code yields the polypeptide sequence (i.e., the polynucleotide sequence "encodes" the polypeptide sequence), one polynucleotide sequence "corresponds" to another polynucleotide sequence if the two sequences encode the same polypeptide sequence.
[0129] A "heterologous" region or domain of a DNA construct is an identifiable segment of DNA within a larger DNA molecule that is not found in association with the larger molecule in nature. Thus, when the heterologous region encodes a mammalian gene, the gene will usually be flanked by DNA that does not flank the mammalian genomic DNA in the genome of the source organism. Another example of a heterologous region is a construct where the coding sequence itself is not found in nature (e.g., a cDNA where the genomic coding sequence contains introns, or synthetic sequences having codons different than the native gene). Allelic variations or naturally-occurring mutational events do not give rise to a heterologous region of DNA as defined herein.
[0130] A "coding sequence" is an in-frame sequence of codons that (in view of the genetic code) correspond to or encode a protein or peptide sequence. Two coding sequences correspond to each other if the sequences or their complementary sequences encode the same amino acid sequences. A coding sequence in association with appropriate regulatory sequences may be transcribed and translated into a polypeptide. A polyadenylation signal and transcription termination sequence will usually be located 3' to the coding sequence. A "promoter sequence" is a DNA regulatory region capable of binding RNA polymerase in a cell and initiating transcription of a downstream (3' direction) coding sequence. Promoter sequences typically contain additional sites for binding of regulatory molecules (e.g., transcription factors) which affect the transcription of the coding sequence. A coding sequence is "under the control" of the promoter sequence or "operatively linked" to the promoter when RNA polymerase binds the promoter sequence in a cell and transcribes the coding sequence into mRNA, which is then in turn translated into the protein encoded by the coding sequence.
[0131] Vectors are used to introduce a foreign substance, such as DNA, RNA or protein, into an organism or host cell. Typical vectors include recombinant viruses (for polynucleotides) and liposomes (for polypeptides). A "DNA vector" is a replicon, such as plasmid, phage or cosmid, to which another polynucleotide segment may be attached so as to bring about the replication of the attached segment. An "expression vector" is a DNA vector which contains regulatory sequences which will direct polypeptide synthesis by an appropriate host cell. This usually means a promoter to bind RNA polymerase and initiate transcription of mRNA, as well as ribosome binding sites and initiation signals to direct translation of the mRNA into a polypeptide(s). Incorporation of a polynucleotide sequence into an expression vector at the proper site and in correct reading frame, followed by transformation of an appropriate host cell by the vector, enables the production of a polypepide encoded by said polynucleotide sequence.
[0132] "Amplification" of polynucleotide sequences is the in vitro production of multiple copies of a particular nucleic acid sequence. The amplified sequence is usually in the form of DNA. A variety of techniques for carrying out such amplification are described in a review article by Van Brunt (1990, Bio/Technol., 8(4):291-294). Polymerase chain reaction or PCR is a prototype of nucleic acid amplification, and use of PCR herein should be considered exemplary of other suitable amplification techniques.
[0133] The general structure of antibodies in vertebrates now is well understood (Edelman, G. M., Ann. N.Y. Acad. Sci., 190: 5 (1971)). Antibodies consist of two identical light polypeptide chains of molecular weight approximately 23,000 daltons (the "light chain"), and two identical heavy chains of molecular weight 53,000-70,000 (the "heavy chain"). The four chains are joined by disulfide bonds in a "Y" configuration wherein the light chains bracket the heavy chains starting at the mouth of the "Y" configuration. The "branch" portion of the "Y" configuration is designated the Fab region; the stem portion of the "Y" configuration is designated the Fc region. The amino acid sequence orientation runs from the N-terminal end at the top of the "Y" configuration to the C-terminal end at the bottom of each chain. The N-terminal end possesses the variable region having specificity for the antigen that elicited it, and is approximately 100 amino acids in length, there being slight variations between light and heavy chain and from antibody to antibody. [0134] The variable region is linked in each chain to a constant region that extends the remaining length of the chain and that within a particular class of antibody does not vary with the specificity of the antibody (i.e., the antigen eliciting it). There are five known major classes of constant regions that determine the class of the immunoglobulin molecule (IgG, IgM, IgA, IgD, and IgE corresponding to γ, μ, α, δ, and ε (gamma, mu, alpha, delta, or epsilon) heavy chain constant regions). The constant region or class determines subsequent effector function of the antibody, including activation of complement (Kabat, E. A., Structural Concepts in Immunology and Immunochemistry, 2nd Ed., p. 413-436, Holt, Rinehart, Winston (1976)), and other cellular responses (Andrews, D. W., et al., Clinical Immunobiology, pp 1-18, W. B. Sanders (1980); Kohl, S., et al., Immunology, 48: 187 (1983)); while the variable region determines the antigen with which it will react. Light chains are classified as either κ (kappa) or λ (lambda). Each heavy chain class can be prepared with either kappa or lambda light chain. The light and heavy chains are covalently bonded to each other, and the "tail" portions of the two heavy chains are bonded to each other by covalent disulfide linkages when the immunoglobulins are generated either by hybridomas or by B cells.
[0135] The expression "variable region" or "VR" refers to the domains within each pair of light and heavy chains in an antibody that are involved directly in binding the antibody to the antigen. Each heavy chain has at one end a variable domain (VR) followed by a number of constant domains. Each light chain has a variable domain (VL) at one end and a constant domain at its other end; the constant domain of the light chain is aligned with the first constant domain of the heavy chain, and the light chain variable domain is aligned with the variable domain of the heavy chain.
[0136] The expressions "complementarity determining region," "hypervariable region," or "CDR" refer to one or more of the hyper-variable or complementarity determining regions (CDRs) found in the variable regions of light or heavy chains of an antibody (See Kabat, E. A. et al., Sequences of Proteins of Immunological Interest, National Institutes of Health, Bethesda, Md., (1987)). These expressions include the hypervariable regions as defined by Kabat et al. ("Sequences of Proteins of Immunological Interest," Kabat E., et al., US Dept. of Health and Human Services, 1983) or the hypervariable loops in 3- dimensional structures of antibodies (Chothia and Lesk, J Mol. Biol. 196 901-917 (1987)). The CDRs in each chain are held in close proximity by framework regions and, with the CDRs from the other chain, contribute to the formation of the antigen binding site. Within the CDRs there are select amino acids that have been described as the selectivity determining regions (SDRs) which represent the critical contact residues used by the CDR in the antibody-antigen interaction (Kashmiri, S., Methods, 36:25-34 (2005)).
[0137] The expressions "framework region" or "FR" refer to one or more of the framework regions within the variable regions of the light and heavy chains of an antibody {See Kabat, E. A. et al., Sequences of Proteins of Immunological Interest, National Institutes of Health, Bethesda, Md., (1987)). These expressions include those amino acid sequence regions interposed between the CDRs within the variable regions of the light and heavy chains of an antibody.

The invention contemplates humanized and chimeric forms of these antibodies. The chimeric antibodies for potential treatment or prevention of photophobia may include an Fc derived from IgGl, IgG2, IgG3, IgG4, IgG5, IgG6, IgG7, IgG8, IgG9, IgGlO, IgGl l, IgG12, IgG13, IgG14, IgG15, IgG16, IgG17, IgG18 or IgG19 constant regions.
[0313] In one embodiment of the invention, the antibodies or VH or VL polypeptides originate or are selected from one or more rabbit B cell populations prior to initiation of the humanization process referenced herein.
[0314] In another embodiment of the invention, the anti-CGRP antibodies and fragments thereof do not have binding specificity for CGRP-R. In a further embodiment of the invention, the anti-CGRP antibodies and fragments thereof inhibit the association of CGRP with CGRP-R. In another embodiment of the invention, the anti-CGRP antibodies and fragments thereof inhibit the association of CGRP with CGRP-R and/or additional proteins and/or multimers thereof, and/or antagonizes the biological effects thereof.
[0315] As stated herein, antibodies and fragments thereof may be modified post- translationally to add effector moieties such as chemical linkers, detectable moieties such as for example fluorescent dyes, enzymes, substrates, bioluminescent materials, radioactive materials, and chemiluminescent moieties, or functional moieties such as for example streptavidin, avidin, biotin, a cytotoxin, a cytotoxic agent, and radioactive materials. [0316] Antibodies or fragments thereof may also be chemically modified to provide additional advantages such as increased solubility, stability and circulating time (in vivo half-life) of the polypeptide, or decreased immunogenicity (See U.S. Pat. No. 4,179,337). The chemical moieties for derivitization may be selected from water soluble polymers such as polyethylene glycol, ethylene glycol/propylene glycol copolymers, carboxymethylcellulose, dextran, polyvinyl alcohol and the like. The antibodies and fragments thereof may be modified at random positions within the molecule, or at predetermined positions within the molecule and may include one, two, three or more attached chemical moieties.
[0317] The polymer may be of any molecular weight, and may be branched or unbranched. For polyethylene glycol, the preferred molecular weight is between about 1 kDa and about 100 kDa (the term "about" indicating that in preparations of polyethylene glycol, some molecules will weigh more, some less, than the stated molecular weight) for ease in handling and manufacturing. Other sizes may be used, depending on the desired therapeutic profile (e.g., the duration of sustained release desired, the effects, if any on biological activity, the ease in handling, the degree or lack of antigenicity and other known effects of the polyethylene glycol to a therapeutic protein or analog). For example, the polyethylene glycol may have an average molecular weight of about 200, 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 5500, 6000, 6500, 7000, 7500, 8000, 8500, 9000, 9500, 10,000, 10,500, 11,000, 11,500, 12,000, 12,500, 13,000, 13,500, 14,000, 14,500, 15,000, 15,500, 16,000, 16,500, 17,000, 17,500, 18,000, 18,500, 19,000, 19,500, 20,000, 25,000, 30,000, 35,000, 40,000, 50,000, 55,000, 60,000, 65,000, 70,000, 75,000, 80,000, 85,000, 90,000, 95,000, or 100,000 kDa. Branched polyethylene glycols are described, for example, in U.S. Pat. No. 5,643,575; Morpurgo et al, Appl. Biochem. Biotechnol. 56:59-72 (1996); Vorobjev et al., Nucleosides Nucleotides 18:2745-2750 (1999); and Caliceti et al, Bioconjug. Chem. 10:638-646 (1999), the disclosures of each of which are incorporated herein by reference.
[0318] There are a number of attachment methods available to those skilled in the art, See e.g., EP 0 401 384, herein incorporated by reference (coupling PEG to G-CSF), See also Malik et al, Exp. Hematol. 20: 1028-1035 (1992) (reporting pegylation of GM-CSF using tresyl chloride). For example, polyethylene glycol may be covalently bound through amino acid residues via a reactive group, such as, a free amino or carboxyl group. Reactive groups are those to which an activated polyethylene glycol molecule may be bound. The amino acid residues having a free amino group may include lysine residues and the N- terminal amino acid residues; those having a free carboxyl group may include aspartic acid residues glutamic acid residues and the C-terminal amino acid residue. Sulfhydryl groups may also be used as a reactive group for attaching the polyethylene glycol molecules. Preferred for therapeutic purposes is attachment at an amino group, such as attachment at the N-terminus or lysine group.
[0319] As suggested above, polyethylene glycol may be attached to proteins via linkage to any of a number of amino acid residues.

Methods of preparing and isolating said clonal population of antigen-specific B cells are taught, for example, in U.S. patent publication no. US 2007/0269868 to Carvalho-Jensen et al., the disclosure of which is herein incorporated by reference in its entirety. Methods of preparing and isolating said clonal population of antigen-specific B cells are also taught herein in the examples. Methods of "enriching" a cell population by size or density are known in the art. See, e.g., U.S. Patent 5,627,052. These steps can be used in addition to enriching the cell population by antigen- specificity.
Methods of Humanizing Antibodies
[0534] In another embodiment, the present invention contemplates methods for humanizing antibody heavy and light chains. Methods for humanizing antibody heavy and light chains which may be applied to anti-CGRP antibodies are taught, for example, in U.S. patent application publication no. US 2009/0022659 to Olson et al., and in U.S. patent no. 7,935,340 to Garcia-Martinez et al., the disclosures of each of which are herein incorporated by reference in their entireties.
Methods of Producing Antibodies and Fragments thereof
[0535] In another embodiment, the present invention contemplates methods for producing anti-CGRP antibodies and fragments thereof. Methods for producing anti- CGRP antibodies and fragments thereof secreted from polyploidal, preferably diploid or tetraploid strains of mating competent yeast are taught, for example, in U.S. patent application publication no. US 2009/0022659 to Olson et al., and in U.S. patent no. 7,935,340 to Garcia-Martinez et al., the disclosures of each of which are herein incorporated by reference in their entireties.
[0536] Other methods of producing antibodies are well known to those of ordinary skill in the art. For example, methods of producing chimeric antibodies are now well known in the art {See, for example, U.S. Patent No. 4,816,567 to Cabilly et al.; Morrison et al, P.N.A.S. USA, 81 :8651-55 (1984); Neuberger, M.S. et al, Nature, 314:268-270 (1985); Boulianne, G.L. et al, Nature, 312:643-46 (1984), the disclosures of each of which are herein incorporated by reference in their entireties).
[0537] Likewise, other methods of producing humanized antibodies are now well known in the art (See, for example, U.S. Patent Nos. 5,530,101, 5,585,089, 5,693,762, and 6,180,370 to Queen et al; U.S. Patent Nos. 5,225,539 and 6,548,640 to Winter; U.S. Patent Nos. 6,054,297, 6,407,213 and 6,639,055 to Carter et al; U.S. Patent No. 6,632,927 to Adair; Jones, P.T. et al, Nature, 321 :522-525 (1986); Reichmann, L., et al, Nature, 332:323-327 (1988); Verhoeyen, M, et al, Science, 239: 1534-36 (1988), the disclosures of each of which are herein incorporated by reference in their entireties).
[0538] Antibody polypeptides of the invention having CGRP binding specificity may also be produced by constructing, using conventional techniques well known to those of ordinary skill in the art, an expression vector containing an operon and a DNA sequence encoding an antibody heavy chain in which the DNA sequence encoding the CDRs required for antibody specificity is derived from a non-human cell source, preferably a rabbit B-cell source, while the DNA sequence encoding the remaining parts of the antibody chain is derived from a human cell source.
[0539] A second expression vector is produced using the same conventional means well known to those of ordinary skill in the art, said expression vector containing an operon and a DNA sequence encoding an antibody light chain in which the DNA sequence encoding the CDRs required for antibody specificity is derived from a non-human cell source, preferably a rabbit B-cell source, while the DNA sequence encoding the remaining parts of the antibody chain is derived from a human cell source. [0540] The expression vectors are transfected into a host cell by convention techniques well known to those of ordinary skill in the art to produce a transfected host cell, said transfected host cell cultured by conventional techniques well known to those of ordinary skill in the art to produce said antibody polypeptides.
[0541] The host cell may be co-transfected with the two expression vectors described above, the first expression vector containing DNA encoding an operon and a light chain- derived polypeptide and the second vector containing DNA encoding an operon and a heavy chain-derived polypeptide. The two vectors contain different selectable markers, but preferably achieve substantially equal expression of the heavy and light chain polypeptides. Alternatively, a single vector may be used, the vector including DNA encoding both the heavy and light chain polypeptides. The coding sequences for the heavy and light chains may comprise cDNA, genomic DNA, or both.
[0542] The host cells used to express the antibody polypeptides may be either a bacterial cell such as E. coli, or a eukaryotic cell such as P. pastoris. In one embodiment of the invention, a mammalian cell of a well-defined type for this purpose, such as a myeloma cell, a Chinese hamster ovary (CHO) cell line, a NSO cell line, or a HEK293 cell line may be used.
[0543] The general methods by which the vectors may be constructed, transfection methods required to produce the host cell and culturing methods required to produce the antibody polypeptides from said host cells all include conventional techniques. Although preferably the cell line used to produce the antibody is a mammalian cell line, any other suitable cell line, such as a bacterial cell line such as an E. co/z-derived bacterial strain, or a yeast cell line, may alternatively be used.
[0544] Similarly, once produced the antibody polypeptides may be purified according to standard procedures in the art, such as for example cross-flow filtration, ammonium sulphate precipitation, affinity column chromatography and the like.
[0545] The antibody polypeptides described herein may also be used for the design and synthesis of either peptide or non-peptide mimetics that would be useful for the same therapeutic applications as the antibody polypeptides of the invention. See, for example, Saragobi et al, Science, 253:792-795 (1991), the contents of which is herein incorporated by reference in its entirety.
Screening Assays
[0546] The invention also includes screening assays designed to assist in the identification of diseases and disorders associated with CGRP especially conditions associated with photophobia such as migraine, other headache and pain conditions, depression, bipolar disorder, agoraphobia and others in patients exhibiting symptoms of photophobia or a CGRP associated disease or disorder.
[0547] In one embodiment of the invention, the anti-CGRP antibodies of the invention, or CGRP binding fragments thereof, are used to detect the presence of CGRP in a biological sample obtained from a patient exhibiting symptoms of a disease or disorder associated with CGRP especially one associated with photophobia. The presence of CGRP, or elevated levels thereof when compared to pre-disease levels of CGRP in a comparable biological sample, may be beneficial in diagnosing a disease or disorder associated with CGRP.
[0548] Another embodiment of the invention provides a diagnostic or screening assay to assist in diagnosis of diseases or disorders associated with CGRP and photophobia in patients exhibiting symptoms of a CGRP associated disease or disorder identified herein, comprising assaying the level of CGRP expression in a biological sample from said patient using a post-translationally modified anti-CGRP antibody or binding fragment thereof. The anti-CGRP antibody or binding fragment thereof may be post-translationally modified to include a detectable moiety such as set forth previously in the disclosure.
[0549] The CGRP level in the biological sample is determined using a modified anti- CGRP antibody or binding fragment thereof as set forth herein, and comparing the level of CGRP in the biological sample against a standard level of CGRP (e.g., the level in normal biological samples). The skilled clinician would understand that some variability may exist between normal biological samples, and would take that into consideration when evaluating results. In one embodiment of the invention, the anti-CGRP antibodies of the invention may be used to correlate CGRP expression levels with a particular stage of cancerous development. One skilled in the art would be able to measure CGRP in numerous subjects in order to establish ranges of CGRP expression that correspond to clinically defined stages of cancerous development. These ranges will allow the skilled practitioner to measure CGRP in a subject diagnosed with a cancer and correlate the levels in each subject with a range that corresponds to a stage of said cancer. One skilled in the art would understand that by measuring CGRP in the patient at different intervals, the progression of the cancer can be determined.
[0550] The above-recited assay may also be useful in monitoring a disease or disorder, where the level of CGRP obtained in a biological sample from a patient believed to have a CGRP associated disease or disorder especially one associated with photophobia is compared with the level of CGRP in prior biological samples from the same patient, in order to ascertain whether the CGRP level in said patient has changed with, for example, a treatment regimen.
[0551] The invention is also directed to a method of in vivo imaging which detects the presence of cells which express CGRP comprising administering a diagnostically effective amount of a diagnostic composition. Said in vivo imaging is useful for the detection or imaging of CGRP expressing tumors or metastases, for example, and can be useful as part of a planning regimen for the design of an effective cancer treatment protocol. The treatment protocol may include, for example, one or more of radiation, chemotherapy, cytokine therapy, gene therapy, and antibody therapy, as well as an anti-CGRP antibody or fragment thereof.
[0552] The present invention further provides for a kit for detecting binding of an anti- CGRP antibody of the invention to CGRP. In particular, the kit may be used to detect the presence of a CGRP specifically reactive with an anti-CGRP antibody of the invention or an immunoreactive fragment thereof. The kit may also include an antibody bound to a substrate, a secondary antibody reactive with the antigen and a reagent for detecting a reaction of the secondary antibody with the antigen. Such a kit may be an ELISA kit and can comprise the substrate, primary and secondary antibodies when appropriate, and any other necessary reagents such as detectable moieties, enzyme substrates, and color reagents, for example as described herein. The diagnostic kit may also be in the form of an immunoblot kit. The diagnostic kit may also be in the form of a chemiluminescent kit (Meso Scale Discovery, Gaithersburg, MD). The diagnostic kit may also be a lanthanide- based detection kit (PerkinElmer, San Jose, CA).
[0553] A skilled clinician would understand that a biological sample includes, but is not limited to, sera, plasma, urine, saliva, mucous, pleural fluid, synovial fluid and spinal fluid.

The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the pharmaceutical compositions of the invention is contemplated. Supplementary active compounds can also be incorporated into the compositions.
[0574] Pharmaceutical compositions typically must be sterile and stable under the conditions of manufacture and storage. The invention contemplates that the pharmaceutical composition is present in lyophilized form. The composition can be formulated as a solution, microemulsion, liposome, or other ordered structure suitable to high drug concentration. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol), and suitable mixtures thereof. The invention further contemplates the inclusion of a stabilizer in the pharmaceutical composition. The proper fluidity can be maintained, for example, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants.
[0575] In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, monostearate salts and gelatin. Moreover, the alkaline polypeptide can be formulated in a time release formulation, for example in a composition which includes a slow release polymer. The active compounds can be prepared with carriers that will protect the compound against rapid release, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, polylactic acid and polylactic, polyglycolic copolymers (PLG). Many methods for the preparation of such formulations are known to those skilled in the art. [0576] For each of the recited embodiments, the compounds can be administered by a variety of dosage forms. Any biologically-acceptable dosage form known to persons of ordinary skill in the art, and combinations thereof, are contemplated. Examples of such dosage forms include, without limitation, reconstitutable powders, elixirs, liquids, solutions, suspensions, emulsions, powders, granules, particles, microparticles, dispersible granules, cachets, inhalants, aerosol inhalants, patches, particle inhalants, implants, depot implants, injectables (including subcutaneous, intramuscular, intravenous, and intradermal), infusions, and combinations thereof.

EXAMPLES
Example 1 Preparation of Antibodies that Bind CGRP
[0586] By using the antibody selection protocol described herein, one can generate an extensive panel of antibodies.
Immunization Strategy
[0587] Rabbits were immunized with human CGRPa (American Peptides, Sunnyvale CA and Bachem, Torrance CA). Immunization consisted of a first subcutaneous (sc) injection of 100 μg of antigen mixed with 100 μg of KLH in complete Freund's adjuvant (CFA) (Sigma) followed by two boosts, two weeks apart each containing 50 μg antigen mixed with 50 μg in incomplete Freund's adjuvant (IF A) (Sigma). Animals were bled on day 55, and serum titers were determined by ELISA (antigen recognition) and by inhibition of CGRP driven cAMP increase in SK-N-MC.
Antibody Selection Titer Assessment
[0588] To identify and characterize antibodies that bind to human CGRPa, antibody- containing solutions were tested by ELISA. Briefly, neutravidin coated plates (Thermo Scientific), were coated with N-term biotinylated human CGRPa (50μί per well, ^g/mL) diluted in ELISA buffer (0.5% fish skin gelatin in PBS pH 7.4,) either for approximately lhr at room temperature or alternatively overnight at 4°C. The plates were then further blocked with ELISA buffer for one hour at room temperature and washed using wash buffer (PBS,0.05% tween 20). Serum samples tested were serially diluted using ELISA buffer. Fifty microliters of diluted serum samples were transferred onto the wells and incubated for one hour at room temperature for one hour. After this incubation, the plate was washed with wash buffer. For development, an anti-rabbit specific Fc-HRP (1 :5000 dilution in ELISA buffer) was added onto the wells and incubated for 45 min at RT. After a 3x wash step with wash solution, the plate was developed using TMB substrate for two minutes at room temperature and the reaction was quenched using 0.5M HC1. The well absorbance was read at 450 nm. Titer determination of serum samples by functional activity (Inhibition of CGRP driven cAMP levels)
[0589] To identify and characterize antibodies with functional activity, an inhibition of CGRP driven increase of cAMP levels assay was done using electrochemiluminescence (Meso Scale Discovery, MSD). Briefly, antibody preparations to be tested were serially diluted in MSD assay buffer (Hepes, MgC12, pH 7.3, lmg/mL blocker A, Meso Scale Discovery) in a 96 well round bottom polystyrene plate (Costar). To this plate, human CGRPa was added (lOng/mL final concentration) diluted in MSD assay buffer and incubated for one hour at 37C. Appropriate controls were used as suggested by the assay- kit manufacturer. Human neuroepithelioma cells (SK-N-MC, ATCC) were detached using an EDTA solution (5mM in PBS) and washed using growth media (MEM, 10% FBS, antibiotics) by centrifugation. The cell number was adjusted to 2 million cells per mL in assay buffer, and IBMX (3-Isobutyl-lMethylxanthine, Sigma) was added to a final concentration of 0.2mM right before loading cells onto cAMP assay plate. After the antibody human CGRPa solution was incubated for one hour 20 microliters of solution containing cells were transferred to the cAMP assay plate. All tested samples were run in duplicates with appropriate controls. Ten microliters of cells were added to the wells and the plate was incubated for 30 minutes with shaking at room temperature. While cells were being incubated with the CGRP solution, the stop solution was prepared by making a 1 :200 solution of TAG labeled cAMP (MSD) in lysis buffer (MSD). To stop the cells-CGRP incubation, 20 microliters of stop solution was added to the cells and the plate was incubated for one hour with shaking at room temperature. The read buffer (MSD) was diluted four times with water and 100 microliters were added to all wells on the plate. The plate was then read using a Sector Imager 2400 (MSD) and the Prism software was used for data fit and IC50 determination.
Tissue Harvesting
[0590] Once acceptable titers were established, the rabbit(s) were sacrificed. Spleen, lymph nodes, and whole blood were harvested and processed as follows: [0591] Spleen and lymph nodes were processed into a single cell suspension by disassociating the tissue and pushing through sterile wire mesh at 70 μιη (Fisher) with a plunger of a 20 cc syringe. Cells were collected in PBS. Cells were washed twice by centrifugation. After the last wash, cell density was determined by trypan blue. Cells were centrifuged at 1500 rpm for 10 minutes; the supernatant was discarded. Cells were resuspended in the appropriate volume of 10% dimethyl sulfoxide (DMSO, Sigma) in FBS (Hyclone) and dispensed at 1 ml/vial. Vials were stored at -70°C in a slow freezing chamber for 24 hours and stored in liquid nitrogen.
[0592] Peripheral blood mononuclear cells (PBMCs) were isolated by mixing whole blood with equal parts of the low glucose medium described above without FBS. 35 ml of the whole blood mixture was carefully layered onto 8 ml of Lympholyte Rabbit (Cedarlane) into a 45 ml conical tube (Corning) and centrifuged 30 minutes at 2500 rpm at room temperature without brakes. After centrifugation, the PBMC layers were carefully removed using a glass Pasteur pipette (VWR), combined, and placed into a clean 50 ml vial. Cells were washed twice with the modified medium described above by centrifugation at 1500 rpm for 10 minutes at room temperature, and cell density was determined by trypan blue staining. After the last wash, cells were resuspended in an appropriate volume of 10% DMSO/FBS medium and frozen as described above.
B cell selection, enrichment and culture conditions
[0593] On the day of setting up B cell culture, PBMC, splenocyte, or lymph node vials were thawed for use. Vials were removed from LN2 tank and placed in a 37°C water bath until thawed. Contents of vials were transferred into 15 ml conical centrifuge tube (Corning) and 10 ml of modified RPMI described above was slowly added to the tube. Cells were centrifuged for 5 minutes at 2K RPM, and the supernatant was discarded. Cells were resuspended in 10 ml of fresh media. Cell density and viability was determined by trypan blue. a) The following protocol was used for Abl and Abl3 [0594] Cells were pre-mixed with the biotinylated human CGRPa as follows. Cells were washed again and resuspended at 1E07 cells/80 μΐ, medium. Biotinylated human CGRPa was added to the cell suspension at the final concentration of 5 ug/mL and incubated for 30 minutes at 4°C. Unbound biotinylated human CGRPa was removed performing two 10 ml washes using PBF [Ca/Mg free PBS (Hyclone), 2 mM ethylenediamine tetraacetic acid (EDTA), 0.5% bovine serum albumin (BSA) (Sigma- biotin free)]. After the second wash, cells were resuspended at 1E07 cells/80 μΐ PBF and 20 μΐ of MACS® streptavidin beads (Miltenyi Biotech, Auburn CA) per 10E7 cells were added to the cell suspension. Cells and beads were incubated at 4°C for 15 minutes and washed once with 2 ml of PBF per 10E7 cells. b) The following protocol was used for Ab4, Ab7, Ab9 and Abll:
[0595] Biotinylated human CGRPa was pre-loaded onto the streptavidin beads as follows. Seventy five microliters of streptavidin beads (Milteny Biotec, Auburn CA) were mixed with N-terminally biotinylated huCGRPa (lOug/ml final concentration) and 300 μΐ PBF. This mixture was incubated at 4°C for 30 min and unbound biotinylated human CGRPa was removed using a MACS® separation column (Miltenyi Biotec, with a 1ml rinse to remove unbound material. Then material was plunged out, then used to resuspend cells from above in lOOul per 1E7 cells, the mixture was then incubated at 4°C for 30min and washed once with 10 ml of PBF.
[0596] For both a) and b) protocols the following applied: After washing, the cells were resuspended in 500μ1 of PBF and set aside. A MACS® MS column (Miltenyi Biotec, Auburn CA) was pre-rinsed with 500 ml of PBF on a magnetic stand (Milteni). Cell suspension was applied to the column through a pre-filter, and unbound fraction was collected. The column was washed with 2.5 ml of PBF buffer. The column was removed from the magnet stand and placed onto a clean, sterile 1.5 ml eppendorf tube. 1 ml of PBF buffer was added to the top of the column, and positive selected cells were collected. The yield and viability of positive cell fraction was determined by trypan blue staining. Positive selection yielded an average of 1% of the starting cell concentration. [0597] A pilot cell screen was established to provide information on seeding levels for the culture. Plates were seeded at 10, 25, 50, 100, or 200 enriched B cells/well. In addition, each well contained 50K cells/well of irradiated EL-4.B5 cells (5,000 Rads) and an appropriate level of activated rabbit T cell supernatant (See U.S. Patent Application Publication No. 20070269868)(ranging from 1-5% depending on preparation) in high glucose modified RPMI medium at a final volume of 250 μΐ/well. Cultures were incubated for 5 to 7 days at 37°C in 4% C02.
B-Cell culture screening by antigen-recognition (ELISA)
[0598] To identify wells producing anti-human CGRPa antibodies, the same protocol as described for titer determination of serum samples by antigen-recognition (ELISA) was used with the following changes. Briefly, neutravidin coated plates were coated with a mixture of both N- and C- terminally biotinylated human CGRPa (50μί per well, ^g/mL each). B-cell supernatant samples (50μί) were tested without prior dilution.
Identification of functional activity in B-cell supernatants using CGRP driven cAMP production
[0599] To determine functional activity contained in B-cell supernatants, a similar procedure to that described for the determination of functional titer of serum samples was used with the following modifications. Briefly, B-cell supernatant (20μί) were used in place of the diluted polyclonal serum samples.
Isolation of antigen-specific B-cells
[0600] Plates containing wells of interest were removed from -70 °C, and the cells from each well were recovered using five washes of 200 microliters of medium (10% RPMI complete, 55 μΜ BME) per well. The recovered cells were pelleted by centrifugation and the supernatant was carefully removed. Pelleted cells were resuspended in 100 μΐ of medium. To identify antibody expressing cells, streptavidin coated magnetic beads (M280 dynabeads, Invitrogen) were coated with a combination of both N- and C- terminal biotinylated human CGRPa. Individual biotinylated human CGRPa lots were optimized by serial dilution. One hundred microliters containing approximately 4x10E7 coated beads were then mixed with the resuspended cells. To this mixture 15 microliters of goat anti- rabbit H&L IgG-FITC (Jackson Immunoresearch) diluted 1 : 100 in medium were added.
[0601] Twenty microliters of cell/beads/anti-rabbit H&L suspension were removed and 5 microliter droplets were dispensed on a one-well glass slide previously treated with Sigmacote (Sigma) totaling 35 to 40 droplets per slide. An impermeable barrier of paraffin oil (JT Baker) was used to submerge the droplets, and the slide was incubated for 90 minutes at 37°C in a 4% C02 incubator in the dark.
[0602] Specific B cells that produce antibody can be identified by the fluorescent ring around produced by the antibody secretion, recognition of the bead-associated biotinylated antigen, and subsequent detection by the fluorescent-lgG detection reagent. Once a cell of interest was identified it was recovered via a micromanipulator (Eppendorf). The single cell synthesizing and exporting the antibody was transferred into a microcentrifuge tube, frozen using dry ice and stored at -70°C.
Amplification and sequence determination of Antibody Sequences From Antigen-Specific B Cells
[0603] Antibody sequences were recovered using a combined RT-PCR based method from a single isolated B-cell. Primers containing restriction enzymes were designed to anneal in conserved and constant regions of the target immunoglobulin genes (heavy and light), such as rabbit immunoglobulin sequences, and a two-step nested PCR recovery was used to amplify the antibody sequence. Amplicons from each well were analyzed for recovery and size integrity. The resulting fragments are then digested with Alul to fingerprint the sequence clonality. Identical sequences displayed a common fragmentation pattern in their electrophoretic analysis. The original heavy and light chain amplicon fragments were then digested using the restriction enzyme sites contained within the PCR primers and cloned into an expression vector. Vector containing subcloned DNA fragments were amplified and purified. Sequence of the subcloned heavy and light chains were verified prior to expression. Recombinant Production of Monoclonal Antibody of Desired Antigen Specificity and/or Functional Properties
[0604] To determine antigen specificity and functional properties of recovered antibodies from specific B-cells, vectors driving the expression of the desired paired heavy and light chain sequences were trans fected into HEK-293 cells.
Antigen-recognition of recombinant antibodies by ELISA
[0605] To characterize recombinant expressed antibodies for their ability to bind to human-CGRPa, antibody-containing solutions were tested by ELISA. All incubations were done at room temperature. Briefly, Immulon IV plagtes (Thermo Scientific), were coated with a CGRPa containing solution (lut/mL in PBS) for 2 hours. CGRPa-coated plates were then washed three times in wash buffer (PBS, 0.05% Tween-20). The plates were then blocked using a blocking solution (PBS, 0.5%> fish skin gelatin, 0.05%> Tween-20) for approximately one hour. The blocking solution was then removed and the plates were then incubated with a dilution series of the antibody being tested for approximately one hour. At the end of this incubation, the plate was washed three times with wash buffer and further incubated with a secondary antibody containing solution (Peroxidase conjugated affinipure F(ab')2 fragment goat anti-human IgG, Fc fragment specific (Jackson Immunoresearch) for approximately 45 minutes and washed three times. At that point a substrate solution (TMB peroxidase substrate, BioFx) and incubated for 3 to 5 minutes in the dark. The reaction was stopped by addition of a HC1 containing solution (0.5M) and the plate was read at 450 nm in a plate-reader.
[0606] Results: Figures 15-18 demonstrate that anti-CGRP antibodies Abl-Abl4 bind to and recognize CGRPa.
Functional characterization of recombinant antibodies by modulation of CGRP driven intracellular cAMP levels and cross reactivity to rats
[0607] To characterize recombinant expressed antibody for their ability to inhibit CGRPa mediated increased cellular levels of cAMP assay, an electrochemiluminescence assay-kit (Meso Scale Discovery, MSD) was used. Briefly, antibody preparations to be tested were serially diluted in MSD assay buffer (Hepes, MgC12, pH 7.3, lmg/mL blocker A,Meso Scale Discovery) in a 96 well round bottom polystyrene plate (Costar). To this plate, human CGRPa was added (25ng/mL final concentration) diluted in MSD assay buffer and incubated for one hour at 37°C. Appropriate controls were used as suggested by the assay-kit manufacturer. Human neuroepithelioma cells (SK-N-MC, ATCC) were detached using an EDTA solution (5mM) and washed using growth media (MEM, 10% FBS, antibiotics) by centrifugation. The cell number was adjusted to 2 million cells per mL in assay buffer, and IB MX (3-Isobutyl-lMethylxanthine, 50mM Sigma) was added to a final concentration of 0.2mM right before loading cells onto cAMP assay plate. The antibody human CGRPa solution was incubated for one hour after which 20 microliters of solution containing cells were transferred to the cAMP assay plate. All tested samples were run in duplicates with appropriate controls. Ten microliters of cells were added to the wells and the plate was incubated for 30 minutes with shaking. While cells were being incubated with the CGRP solution, the stop solution was prepared by making a 1 :200 solution of TAG labeled cAMP (MSD) in lysis buffer (MSD). To stop the cells-CGRP incubation, 20 microliters of stop solution was added to the cells and the plate was incubated for one hour with shaking. The read buffer (MSD) was diluted four times with water and 100 microliters were added to all wells on the plate. The plate was then read using a Sector Imager 2400 (MSD) and the Prism software was used for data fit and IC50 determination.
[0608] To test for the ability of recombinant antibodies to antagonize human CGRP a similar assay was performed with the substitution of the CGRP agonist (CGRP lOng/mL final concentration). Evaluation of the recombinant antibodies to recognize and inhibit rat CGRP -mediated cAMP generation was conducted using rat CGRP (5ng/mL final concentration) and the rat L6 cell line (ATCC).
[0609] Results: Figures 19-37 demonstrate that anti-CGRP antibodies AM -AM 4 inhibit CGRPa, CGRP , and rat CGRP mediated increased cellular levels of cAMP. Example 2: Enzymatic Production of Fab Fragments
[0610] Papain digestions were conducted using immobilized papain (Thermo/Pierce) as per manufacturer's instructions. Briefly, purified antibodies were incubated in a cystein/HCl-containing buffer with immobilized papain at 37°C with gentle rocking. The digestion was monitored by taking an aliquot and analyzing using SDS-PAGE for cleavage of the heavy chain. To stop the reaction, the immobilized papain was spun out and washed using 50 mM Tris pH 7.5 and filtered. Undigested full length antibody and Fc fragments were removed by using a MabSelectSure (GE) column.
Example 3 Yeast Cell Expression
Construction of Pichia pastoris expression vectors for heavy and light chain.
[0611] The humanized light and heavy chain fragments were commercially synthesized and subcloned into a pGAP expression vector. The pGAP expression vector uses the GAP promoter to drive expression of the immunoglobulin chain and the human serum albumin (HSA) leader sequence for export. In addition, this vector contains common elements such as a bacterial origin of replication, and a copy of the kanamycin resistance gene which confers resistance to the antibiotic G418 in P. pastoris. G418 provides a means of selection for strains that contain the desired expression vector integrated into their genome.
Transformation of expression vectors into haploid metl and lys3 host strains of Pichia pastoris
[0612] All methods used for transformation of haploid P. pastoris strains and manipulation of the P. pastoris sexual cycle were done as described in Pichia Protocols (Methods in Molecular Biology Higgings, DR, and Cregg, JM, Eds. 1998. Humana Press, Totowa, NJ). Prior to transformation each vector was linearized within the GAP promoter sequences to direct the integration of the vector into the GAP promoter locus of the P. pastoris genome. Haploid strains were transfected using electroporation and successful transformants were selected on YPDS (yeast extract, peptone dextrose with sorbitol) G418 agar plates. Copy numbers of heavy and light chain genes were determined for haploid strains by Southern blot analysis. Haploid strains were then mated and selected for their ability to grow in the absence of the amino acid markers (i.e., Lys and Met). Resulting diploid clones were then subjected to a final Southern blot to confirm copy numbers of heavy and light chain genes. A clone expressing the antibody of interest was selected using biolayer interferometry Protein- A biosensors to monitor expression (Octet, ForteBio).
Example 4 Expression of Ab3, Ab6 and Abl4 in Pichia pastoris
[0613] Three Pichia strains for expression of full-length antibody were made. For all the full length antibody expressing strains, haploids strains were created and subsequently mated. One haploid strain expressed full-length light chain sequence and another haploid strain expressed the full-length heavy chain sequence. Each diploid strain was used to generate a research cell bank and used for expression in a bioreactor.
[0614] First an inoculum was expanded using the research cell bank using medium comprised of the following nutrients (%w/v): yeast extract 3%, anhydrous dextrose 4%, YNB 1.34%, Biotin 0.004% and 100 mM potassium phosphate. To generate the inoculum for the fermenters, the cell bank was expanded for approximately 24 hours in a shaking incubator at 30°C and 300 rpm. A 10% inoculum was then added to Labfors 2.5L working volume vessels containing 1 L sterile growth medium. The growth medium was comprised of the following nutrients: potassium sulfate 18.2 g/L, ammonium phosphate monobasic 36.4 g/L, potassium phosphate dibasic 12.8 g/L, magnesium sulfate heptahydrate 3.72 g/L, sodium citrate dihydrate 10 g/L, glycerol 40 g/L, yeast extract 30 g/L, PTM1 trace metals 4.35 mL/L, and antifoam 204 1.67 mL/L. The PTM1 trace metal solution was comprised of the following components: cupric sulfate pentahydrate 6 g/L, sodium iodide 0.08 g/L, manganese sulfate hydrate 3 g/L, sodium molybdate dihyrate 0.2 g/L, boric acid 0.02 g/L, cobalt chloride 0.5 g/L, zinc chloride 20 g/L, ferrous sulfate heptahydrate 65 g/L, biotin 0.2 g/L, and sulfuric acid 5 mL/L.
[0615] The bioreactor process control parameters were set as follows: Agitation 1000 rpm, airflow 1.35 standard liter per minute, temperature 28°C and pH was controlled at six using ammonium hydroxide. No oxygen supplementation was provided.
[0616] Fermentation cultures were grown for approximately 12 to 16 hours until the initial glycerol was consumed as denoted by a dissolved oxygen spike. The cultures were starved for approximately three hours after the dissolved oxygen spike. After this starvation period, a bolus addition of ethanol was added to the reactor to reach 1% ethanol (w/v). The fermentation cultures were allowed to equilibrate for 15 to 30 minutes. Feed addition was initiated 30 minutes post-ethanol bolus and set at a constant rate of 1 mL/min for 40 minutes, then the feed pump was controlled by an ethanol sensor keeping the concentration of ethanol at 1% for the remainder of the run using an ethanol sensing probe (Raven Biotech). The feed was comprised of the following components: yeast extract 50 g/L, dextrose 500 g/L, magnesium sulfate heptahydrate 3 g/L, and PTM1 trace metals 12 mL/L. For fermentation of the full length Ab6 and Abl4, sodium citrate dihydrate (0.5g/L) was also added to the feed. The total fermentation time was approximately 90 hours.
Example 5 Methods of Humanizing Antibodies
[0617] Methods of humanizing antibodies have been described previously in issued U.S. Patent No. 7935340, the disclosure of which is incorporated herein by reference in its entirety. In some instances, a determination of whether additional rabbit framework residues are required to maintain activity is necessary. In some instances the humanized antibodies still requires some critical rabbit framework residues to be retained to minimize loss of affinity or activity. In these cases, it is necessary to change single or multiple framework amino acids from human germline sequences back to the original rabbit amino acids in order to have desired activity. These changes are determined experimentally to identify which rabbit residues are necessary to preserve affinity and activity. This is now the end of the variable heavy and light chain humanized amino acid sequence.
Example 6 Inhibition of CGRP Binding to its Cellular Receptor
[0618] To characterize recombinantly expressed antibodies for their ability to inhibit CGRP binding to its cellular receptor, a radioligand-binding assay was performed as previously described [Elshourbagy et al, Endocrinology 139: 1678 (1998); Zimmerman et al, Peptides, 16:421 (1995)]. Membrane preparations of recombinant human CGRP receptors, calcitonin receptor- like receptor and RAMP1 (Chemiscreen, Millipore) were used. Antibody dilutions were preincubated with 125I radiolabeled human CGRPa (0.03nM) for 30 minutes at room temperature. Non-specific binding was estimated in the presence of 0.1 μΜ human CGRPa. Membranes were filtered and washed. The filters were then counted to determine 125I radiolabeled human CGRPa specifically bound.
[0619] Results: Figure 38 demonstrates that anti-CGRP antibodies Abl-Abl3 inhibit CGRP binding to its cellular receptor.
Example 7 Inhibition of Neurogenic Vasodilation by Anti-CGRP Antibodies in Rats
[0620] CGRP is a potent vasodilator (Nature 313: 54-56 (1985) and Br J. Clin. Pharmacol. 26(6):691-5. (1988)). A pharmacodynamic assay to measure CGRP receptor antagonist activity non-invasively was used to characterize anti-CGRP antibodies. The model relied on changes in dermal blood flow measured using a laser Doppler imaging following the topical application of a capsaicin solution. Capsaicin activates the transient receptor potential vanilloid type 1 receptor (TRPV-1), producing neurogenic inflammation and vasodilatation via the local release of vasoactive mediators including CGRP and substance P (Br. J. Pharmacol. 110: 772-776 (1993)).
[0621] On the day prior to the vasodilatation assay, animals were dosed with the test agent or control via IP (intraperitoneal). Following dosing, the animals were shaved and depilated in the lower back region of their dorsal side, in an area approximately 2x6cm. The animals were then returned to their cages overnight. On the day of test, approximately 24 hours post dosing, animals were anesthetized with isoflurane gas and placed on a temperature controlled heating pad and fitted with a nose cone for continuous delivery of isoflurane. A laser doppler imager was used for the observation of vasodilatation. A beam of coherent red light generated by a 633 nm helium-neon laser was directed to the shaved area, a rectangle (2x6 cm), and scanned at a medium resolution mode. A baseline Doppler scan was obtained first and the location of O-ring placement predetermined by identifying two similar low flux areas. Two rubber Orings (~lcm in diameter) were placed in the selected regions and a baseline scan was performed. Immediately after completion of the scan, lmg of capsaicin in 5 of an ethanol: acetone solution (1 : 1) was applied within each of the two O-rings Doppler scans were repeated at 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5 and 30 minutes after the application of capsaicin. Percent change from baseline mean Flux within each of the two O-rings, was plotted as the results of vasodilatation due to capsaicin.
[0622] In order to test recombinantly expressed antibodies for their ability to inhibit CGPvP binding to its cellular receptor, a radioligand-binding assay was performed as previously described.

Example 8 Inhibition of Light Aversion or Photophobia by Systemic (IP) Injection of Anti-CGRP Antibody in Transgenic Nestin/Rampl Mice
[0624] As discussed supra, one of the hallmarks of migraines is photophobia, or increased sensitivity to light [Mulleners et al, Headache 41 : 31-39 (2001); Recober et al, J. Neuroscience 29:8798:8804 (2009)]. It is also known that migraineurs, but not non- migraineurs, are sensitive to CGRP -induced headache [reviewed in Neurology 22:241-246 (2009)]. CGRP binds to a G protein coupled receptor called CLR (calcitonin like receptor) that works concomitantly with the receptor activity-modifying protein 1 (RAMPl) in mediating CGRP binding and signaling. In-vitro, the activity of CGRP is strongly enhanced by overexpression of the RAMPl subunit of the CGRP receptor [(J. Neurosci. 27:2693-2703 (2007)]. To study light aversion behavior in mice, a nestin/human-RAMPl transgenic mouse model was developed [Recober et al, J. Neuroscience 29: 8798-8804 (2009); Russo et al, Mol. Cell. Pharmacol, 1 :264-270 (2009)]. These mice when exposed to CGRP present symptoms associated with migraines in particular light aversion (ibid). This protocol is detailed below.
[0625] To test the ability of anti-CGRP antibodies to block CGRP-induced light aversion or photophobia, mice are housed under standard conditions in groups of 2-5 per cage with a 12 hour light cycle (lights on at 0500 CST)/0600 CDT and off at 1700 CST/1800 CDT) and access to water and food ad libitum. The mice used in the studies are comprised in mice colonies of genotype nestin/hRAMP 1 that contain two transgene alleles Tg(Nes-cre)lKln/J and Tg(RAMPl) alleles (B6;SJL-Tg(Nes-cre)lKln Tg(RAMPl). Nes- cre was introduced in these mice by an intercross involving mice obtained from The Jackson Laboratory (stock 003771) on a B6 genetic background yielding mice. [0626] The control mice used in the protocol are littermates that are either non- transgenic, or single transgenic (not expressing hRAMPl) containing either transgene: nestin-cre or Cxl-GFP-hRAMPl . The stock colony is maintained by backcrossing CX1- GFP-hRAMPl mice with non-transgenic littermates in the barrier facility. For behavior studies, the colony is maintained by crossing CXl-GFP-hRAMPl single transgenic with nestin-cre mice in non-barrier facilities. All of these mice are cared for by animal care and procedures approved by the University of Iowa Animal Care and Use Committee and further are performed in accordance with the standard set by the National Institutes of Health.
[0627] The materials and equipment used in this protocol include a light-dark box and testing chambers comprising a plexiglass open field (27 x 27 x 20.3 cm) containing 16 beam infrared arrays (Med Associates Inc., St. Albans, VT). The light/dark box is divided in two equally sized zones by a dark insert that is opaque to visible light. There is an opening (5.2 x 6.8 cm) in the dark insert that allows the mouse to freely move between the two zones. This testing chamber is placed inside a sound-attenuating cubicle (56 x 38 x 36 cm) with a fan for ventilation (Med Associates Inc.). There are six chambers for the overall system that integrates with a computer containing software for recording and data collection (Med Associates Inc.).
[0628] The software used to monitor results is Activity Monitor v 6.02 (Med Associates Inc.). The software settings used for recording comprise: Resolution (ms): 50, Box Size: 3, Resting Delay (ms): 500, Ambulatory Trigger: 3, Session Type: C, Session Time (min): 20, Block Interval (sec): 300, and Compressed File: DEFAULT.ZIP.
[0629] In the protocol, the light source for each chamber is an LED panel, which was installed to the ceiling of the sound-attenuating cubicle. The LED panel contains 36 collimated - 1 watt LED bulbs (5500k Daylight White) (LEDwholesalers, Burlingame, CA). To control light intensity, each LED panel is connected to a dimmable LED driver (LINEARdrive; eldoLED America Inc., San Jose, CA) leading to a potential range of light intensity from -300 to 27,000 lux. The standard light intensity is -1000-1200 lux unless otherwise stated. Alternatively, lower light intensities have been achieved by using layers of wax paper to filter the light leading to an intensity of -55 lux. [0630] The injectors used are hand-made by inserting a stripped 30 gauge x ½" needle into non-radiopaque polyethylene tubing (inner diameter .38 mm; outer diameter 1.09 mm). Using the tubing described above, a stopper (~lcm in length) is placed over the needle leaving approximately 2.5 mm of the bevel uncovered. These injectors are connected to a 10 μΐ^ Hamilton syringe.
[0631] The mice are injected with rat a-CGRP (Sigma) diluted in Dulbecco phosphate- buffered saline (D-PBS) (Hyclone). The total dose delivery is 0.5 nmol. For example, 250 or 500 μg CGRP is diluted in 250 or 500 sterile PBS for a final concentration of 1 μg/μL. The CGRP is stored at-20°C and aliquots are freeze-thawed at most one time. The PBS is stored at 4°C.
[0632] The mice are administered one of the anti-CGRP antibodies disclosed herein (Ab3), vehicle or a control antibody, which are stored at 4°C prior to administration. In this protocol prior to the administration of the CGRP i.e., approximately 24 hours prior to testing, the mice are weighed and then receive an intraperitoneal (ip) injection of either: vehicle, control antibody, or CGRP -binding antibody at a dosage of 30 mg/kg. The mice are also screened to detect any abnormal physical conditions that could affect the assay such as a missing eye, cataracts, or other abnormalities such as grooming, etc. The day after antibody administration, mice are transported in cages from animal housing on a cart and then the mice are placed in the behavior room for acclimation at least 1 hour prior to any injection or testing. Any coverings required for transport are removed from the cages and normal light conditions (standard overhead fluorescent lighting) are turned on during acclimation and remain on for the remainder of the procedure. In addition, all equipment that produces sound including anesthetic devices, light/dark chambers, and LED panels are turned on during acclimation and remain until testing is complete. Typically there is minimal human presence in the room during acclimation.
[0633] After acclimation each mouse is placed in an induction chamber and administered 3.5% isoflurane. After the mouse is anesthetized, it is transferred to a nose cone maintaining 3.5% isoflurane administration, so that it remains anesthetized during injection. Thereafter drug administration is effected using the injector by direct injection into the right lateral ventricle through the intact scalp aiming at 1 mm posterior to bregma and 1 mm right from the midline.
[0634] Typically for consistency all the injections are performed by the same person after a period of training yielding a success rate of >90% as demonstrated by injections of dye into the ventricles. The drugs injected are either 2.0 μΙ_, vehicle (D-PBS) μΙ_, or 2.0 μg CGRP in 2.0 vehicle (1 μg/μL) administered as a direct intracerebroventricular injection into the right lateral ventricle of the brain through the intact scalp aiming at 1 mm posterior to bregma and 1 mm right from the midline as described before [Recober et al, J. Neuroscience 29: 8798-8804 (2009)] After all 2.0 μΙ_, is delivered, the needle remains in place for 10 sec and then removed. The time of injection is then recorded.
[0635] After injection the mice are allowed to recover for 30 minutes prior to testing in an empty, uncovered cage containing a paper towel for bedding. During recovery, the following is recorded: diarrhea, excessive urination, bleeding post-injection, abnormal behavior such as lack of movement, seizures, etc. After a 30 minute recovery testing is effected. Each mouse is placed along the back wall (furthest from the opening between the two zones) in the light zone approximately in the center. This triggers the recording to begin. Up to six mice are tested at one time (one mouse per chamber). During testing the shelf with the chamber is pushed back into the cabinet and the doors closed. The software records mouse movement for 20 minutes. After the recording is completed, each mouse is removed and placed back in home cage for transport back to animal housing.
[0636] Results
[0637] Using this protocol an anti-CGRP antibody developed by Alder Biopharmaceuticals (Ab3) was tested to determine its potential suitability for treating migraine, particularly chronic migraine in human subjects and more particularly for treatment or prevention of CGRP-associated photophobia. The results of these studies are shown in Figure 41 and Figure 42. Figure 41 contains data that compares the effect of ICV injection of CGRP in hRAMPl tg mice and control littermate mice. The data reveals that the CGRP administration results in decreased time in light behavior in the hRAMPl tg mice relative to their control littermates. [0638] Figure 42 contains data which compares the effect of systemic (IP) injection of anti-CGRP antibody (Ab3) in vehicle, vehicle alone, and control antibody in vehicle in nestin/RAMP 1 mice which are administered these moieties intraperitoneally at 30 mg/kg about 24 hours prior to administration of CGRP. The data in the left side of the graph is the total time in light (seconds) for the first 10 minutes, and the data on the right side of the graph is the total time in light (seconds) for the first 20 minutes measured after CGRP injection (administered via ICV injection) and the recovery period. Light intensity in light zone was approximately lxl 03 lx. The data reveal that the mice who received the anti- CGRP antibody Ab3 according to the invention had a statistically significant increase in the amount of time spent in the light relative to the mice who received the controls.
[0639] These results indicate that Ab3 inhibits CGRP-associated photophobia or light aversion and should be well suited for treating migraine or other disorders that involve photophobia, especially CGRP related photophobia. Based it is anticipated that other anti- CGRP antibodies including others disclosed herein may behave similarly. These results further indicate that the subject light aversion behavior assay may be used to assess the potential therapeutic efficacy (ability to antagonize effects of CGRP in vivo) of candidate of anti-CGRP antibodies and antibody fragments. This was unanticipated as it was unforseeable that a large polypeptide such as an anti-CGRP antibody would go through the blood-brain barrier and inhibit photophobia or light aversion.
[0640] The results reveal that the excess CGRP that induces light aversive behavior in mice is reduced by the systemic administration of anti-CGRP antibody suggesting that the antibody is able to bind a sufficient amount of the circulating CGRP to counteract the light aversive behavior. These results suggest that the anti-CGRP antibody may be crossing the blood-brain barrier and thereby inhibiting the neurological effects of CGRP, in particular migraine associated photophobia and pain.
[0641] This is the first demonstration that the subject animal light aversive behavior assay may be used to assess therapeutic efficacy of a polypeptide such as an anti-CGRP antibody or anti-CGRP antibody fragment. In addition these results suggest that this animal model potentially may be useful in determining effective dosages of a candidate anti-CGRP antibody or antibody fragment, effective modes of administration, as well as a suitable dosage regimen.
