Definitions

  • This invention relates to methods of treating, preventing, modifying and managing pain, which comprise the administration of immunomodulatory compounds alone or in combination with known therapeutics.
  • the invention also relates to pharmaceutical compositions and dosing regimens.
  • the invention encompasses the use of immunomodulatory compounds in conjunction with neural blockade and/or other standard therapies for pain syndrome.
  • Pain is a leading symptom of many different disorders and is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.
  • Pain leads to severe impairment of functional ability, which compromises the working, social, and family lives of sufferers. Around five percent ofthe adult population is estimated to suffer from pain sufficiently severe to cause significant disability.
  • Chojnowska E Stannard C. Epidemiology of Chronic Pain, Chapter 2, pp 15-26: T.S. Jensen, P.R. Wilson, A.S.C. Rice eds., Clinical Pain Management Chronic Pain, Arnold, London, 2003. In most pain conditions, there is an increased neural input from the periphery.
  • Sensory nerve impulses travel via the axons of primary afferent neurons to the dorsal horn ofthe spinal cord, where they propagate nerve impulses to dorsal horn neurons by releasing excitatory amino acids and neuropeptides at synapses.
  • Dorsal horn projection neurons process and transfer the information about a peripheral stimuli to the brain via ascending spinal pathways. Mannion, R.J. and Woolf, C.J., Clin. J. of Pain 7 ⁇ 5:S144-S156 (2000).
  • dorsal horn projection neurons The firing of dorsal horn projection neurons is determined not only by the excitatory input they receive, but also by inhibitory input from the spinal cord and higher nerve centers.
  • Several brain regions contribute to descending inhibitory pathways. Nerve fibers from these pathways release inhibitory substances such as endogenous opioids, ⁇ - aminobutyric acid ("GAB A"), and serotonin at synapses with other neurons in the dorsal horn, or primary afferent neurons and inhibit nociceptive transmission.
  • GABA A ⁇ - aminobutyric acid
  • Peripheral nerve injury can produce changes in dorsal horn excitability by down-regulating the amount of inhibitory control over dorsal horn neurons through various mechanisms.
  • Central sensitization may explain, in part, the continuing pain and hyperalgesia that occurs following an injury, and may serve an adaptive purpose by encouraging protection of the injury during the healing phase. Central sensitization, however, can persist long after the injury has healed thereby supporting chronic pain. Sensitization also plays a key role in chronic pain, helping to explain why it often exceeds the provoking stimulus, both spatially and temporally, and may help explain why established pain is more difficult to suppress than acute pain. Koltzenburg, M. Clin. J. of Pain 75.S131-S138 (2000). 2.1 TYPES OF PAIN
  • Nociceptive pain is elicited when noxious stimuli such as inflammatory chemical mediators are released following tissue injury, disease, or inflammation and are detected by normally functioning sensory receptors (nociceptors) at the site of injury. Koltzenburg, M. Clin. J. of Pain i(5:S131-S138 (2000). Clinical examples of nociceptive pain include but are not limited to pain associated with chemical or thermal burns, cuts and contusions ofthe skin, osteoarthritis, rheumatoid arthritis, tendonitis, and myofascial pain.
  • Nociceptors are distributed throughout the periphery of tissue. They are sensitive to noxious stimuli (e.g., thermal, mechanical, or chemical) which would damage tissue if prolonged. Activation of peripheral nociceptors by such stimuli excites discharges in two distinct types of primary afferent neurons: slowly conducting unmyelinated c-fibers and more rapidly conducting, thinly myelinated A ⁇ fibers. C-fibers are associated with burning pain and A ⁇ fibers with stabbing pain. Koltzenburg, M. Clin. J. of Pain 76:S131-S138 (2000); Besson, J.M. Lancet 555:1610-15 (1999); and Johnson, B.W.
  • noxious stimuli e.g., thermal, mechanical, or chemical
  • Pain Mechanisms Anatomy, Physiology and Neurochemistry, Chapter 11 in Practical Management of Pain ed. P. Prithvi Raj. (3 rd Ed., Mosby, Inc. St Louis, 2000). Most nociceptive pain involves signaling from both A ⁇ and c-types of primary afferent nerve fibers. Peripheral nociceptors are sensitized by inflammatory mediators such as prostaglandin, substance P, bradykinin, histamine, and serotonin, as well as by intense, repeated, or prolonged noxious stimulation. In addition, cytokines and growth factors (e.g., nerve growth factor) can influence neuronal phenotype and function. Besson, J.M. Lancet 555:1610-15 (1999).
  • nociceptors When sensitized, nociceptors exhibit a lower activation threshold and an increased rate of firing, which means that they generate nerve impulses more readily and more frequently. Peripheral sensitization of nociceptors plays an important role in spinal cord dorsal horn central sensitization and clinical pain states such as hyperalgesia and allodynia.
  • Inflammation also appears to have another important effect on peripheral nociceptors.
  • Some C-nociceptors do not normally respond to any level of mechanical or thermal stimuli, and are only activated in the presence of inflammation or in response to tissue injury. Such nociceptors are called “silent" nociceptors, and have been identified in visceral and cutaneous tissue. Besson, J.M. Lancet 555:1610-15 (1999); Koltzenburg, M. Clin. J. of Pain io ⁇ :S131-S138 (2000). Differences in how noxious stimuli are processed across different tissues contribute to the varying characteristics of nociceptive pain.
  • cutaneous pain is often described as a well-localized sharp, prickling, or burning sensation whereas deep somatic pain may be described as diffuse, dull, or an aching sensation.
  • pain perception and stimulus intensity there is a variable association between pain perception and stimulus intensity, as the central nervous system and general experience influence the perception of pain.
  • Neuropathic Pain reflects injury or impairment ofthe nervous system, and has been defined by the IASP as "pain initiated or caused by a primary lesion or dysfunction in the nervous system.”
  • IASP International Association for the Study of Pain (IASP) Task Force on Taxonomy, IASP Press: Seattle, 209-214, 1994.
  • Some neuropathic pain is caused by injury or dysfunction ofthe peripheral nervous system.
  • changes in the expression of key transducer molecules, transmitters, and ion channels occur, leading to altered excitability of peripheral neurons. Johnson, B.W.
  • neuropathic pain include but are not limited to pain associated with diabetic neuropathy, postherpetic neuralgia, trigeminal neuralgia, and post- stroke pain.
  • Neuropathic pain is commonly associated with several distinct characteristics, such as pain which may be continuous or episodic and is described in many ways, such as burning, tingling, prickling, shooting, electric-shock-like, jabbing, squeezing, deep aching, or spasmodic.
  • Paradoxically partial or complete sensory deficit is often present in patients with neuropathic pain who experience diminished perception of thermal and mechanical stimuli. Abnormal or unfamiliar unpleasant sensations (dysaesthesias) may also be present and contribute to patient suffering. Other features are the ability of otherwise non-noxious stimuli to produce pain (allodynia) or the disproportionate perception of pain in response to supra-threshold stimuli (hyperalgesia). Johnson, B.W. Pain Mechanisms: Anatomy, Physiology and Neurochemistry, Chapter 11 in Practical Management of Pain ed. P. Prithvi Raj. (3 rd Ed., Mosby, Inc. St Louis, 2000); and Attal, N. Clin. J. of Pain 16:S118-S130 (2000).
  • CRPS Complex regional pain syndrome
  • CRPS type I encompasses the condition known as reflex sympathetic dystrophy (RSD)
  • CRPS type II encompasses the condition known as causalgia and both types have subsets consistent with sympathetic maintained pain syndrome.
  • RSD reflex sympathetic dystrophy
  • CRPS type II encompasses the condition known as causalgia and both types have subsets consistent with sympathetic maintained pain syndrome.
  • a special consensus conference ofthe IASP addressed diagnosis and terminology ofthe disease, and endorsed the term CRPS with the two subtypes. Subsequent studies and conferences have refined the definitions such that the current guidelines give high sensitivity (0.70) with very high specificity (0.95).
  • CRPS is a multi-symptom and multi-system syndrome affecting multiple neural, bone and soft tissues, including one or more extremities, which is characterized by an intense pain.
  • CRPS remains poorly understood.
  • changes in peripheral and central somatosensory, autonomic, and motor processing, and a pathologic interaction of sympathetic and afferent systems have been proposed as underlying mechanisms.
  • Wasner et al. demonstrated a complete functional loss of cutaneous sympathetic vasoconstrictor activity in an early stage of CRPS with recovery.
  • CRPS Crohn's disease .
  • Various causes that have led to CRPS include but are not limited to head injury, stroke, polio, tumor, trauma, amylotrophic lateral sclerosis (ALS), myocardial infarction, polymyalgia rheumatica, operative procedure, brachial plexopathy, cast/splint immobilization, minor extremity injury and malignancy.
  • ALS amylotrophic lateral sclerosis
  • Symptoms of CRPS include but are not limited to pain, autonomic dysfunction, edema, movement disorder, dystrophy, and atrophy. Schwartzman R.J., NEngl JMed 343(9): 654-6 (2000). The pain is described as extremely severe and unrelenting, often with a burning character. Ninety percent of all CRPS patients complain of spontaneous burning pain and allodynia, which refers to pain with light touch. Much ofthe difficulty clinicians have with this syndrome is the fact that pain may be far worse than what would be expected based on physical findings. Id. Pain is also accompanied by swelling and joint tenderness, increased sweating, sensitivity to temperature and light touch, as well as color change to the skin. In fact, the diagnosis of CRPS cannot be made on reports of pain alone. Patients must have signs and symptoms of sensory abnormalities as well as vascular dysfunction accompanied by excessive sweating, edema or trophic changes to the skin.
  • CRPS type I also referred to as RSD
  • CRPS type II also referred to as causalgia
  • RSD CRPS type I
  • CRPS type II occurs after nerve injury.
  • CRPS is further divided into three distinct stages in its development and manifestation. However, the course ofthe disease seems to be so unpredictable between various patients that staging is not always clear or helpful in treatment. Schwartzman R.J., NEnglJMed 343(9): 654 (2000).
  • stage I Pain is more severe than would be expected from the injury, and it has a burning or aching quality. It may be increased by dependency ofthe limb, physical contact, or emotional upset.
  • the affected area typically becomes edematous, may be hyperthermic or hypothermic, and may show increased nail and hair growth.
  • Radiographs may show early bony changes. Id.
  • stage II or "established RSD”
  • edematous tissue becomes indurated. Skin typically becomes cool and hyperhidrotic with livedo reticularis or cyanosis. Hair may be lost, and nails become ridged, cracked, and brittle. Hand dryness becomes prominent, and atrophy of skin and subcutaneous tissues becomes noticeable. Pain remains the dominant feature. It is usually constant and is increased by any stimulus to the affected area. Stiffness develops at this stage. Radiographs may show diffuse osteoporosis. Id.
  • stage III Pain spreads proximally. Although it may diminish in intensity, pain remains a prominent feature. Flare-ups may occur spontaneously. Irreversible tissue damage occurs, and the skin is typically thin and shiny. Edema is absent, but contractures may occur. X-ray films typically indicate marked bone demineralization. Id. h all stages of CRPS, patients endure severe chronic pain and most patients are sleep deprived. CRPS has significant morbidity and thus raising awareness ofthe disease is important. Early and effective treatment may lessen the effect of CRPS in some individuals. William D. Dzwierzynski et al, Hand Clinics Nol 10 (1): 29-44 (1994). 2.1.3 Other Types of Pain
  • Visceral pain has been conventionally viewed as a variant of somatic pain, but may differ in neurological mechanisms. Visceral pain is also thought to involve silent nociceptors, visceral afferent fibers that only become activated in the presence of inflammation. Cervero, F. and Laird J.M.A., Lancet 555:2145-48 (1999).
  • Headaches can be classified as primary and secondary headache disorders.
  • the pathophysiology ofthe two most common primary disorders, i.e., migraine and tension-type headache, is complex and not fully understood.
  • nociceptive input to the CNS may be increased due to the activation and sensitization of peripheral nociceptors, and the barrage of nociceptive impulses results in the activation and sensitization of second- and third-order neurons in the CNS.
  • central sensitization plays a role in the initiation and maintenance of migraine and tension-type headache. Johnson, B.W.
  • Pain Mechanisms Anatomy, Physiology and Neurochemistry, Chapter 11 in Practical Management of Pain ed. P. Prithvi Raj. (3 rd Ed., Mosby, Inc. St Louis, 2000).
  • Post-operative pain such as that resulting from trauma to tissue caused during surgery, produces a barrage of nociceptive input.
  • cytokines, neuropeptides and other inflammatory mediators These chemicals are responsible for the sensitization and increased responsiveness to external stimuli, resulting in, for example, lowering ofthe threshold and an increased response to supra-threshold stimuli. Together, these processes result in peripheral and central sensitization.
  • Mixed pain is chronic pain that has nociceptive and neuropathic components. For example, a particular pain can be initiated through one pain pathway and sustained through a different pain pathway. Examples of mixed pain states include, but are not limited to, cancer pain and low back pain.
  • CRPS related pain includes pain management and extensive physical therapy, which can help to prevent edema and joint contractures and can also help to minimize pain.
  • medication and neural blockade are used to help with the severe pain.
  • Regional neural blockade is performed using Bier blocks with a variety of agents, including local anesthetics, bretylium, steroids, calcitonin, reserpine, and guanethidine.
  • Perez R.S. et al, JPain Symptom Manage 2001 Jun; 21(6): 511-26.
  • selective sympathetic ganglia neural blockade is performed for both diagnostic and therapeutic purposes. The rationale for selective neural blockade is to interrupt the sympathetic nervous system and reduce the activation ofthe sensory nerves.
  • CRPS sympathetic-independent neural blockade
  • pain is typically lifelong and may be severe enough to be debilitating.
  • Medications presently used during the treatment of chronic pain in general include non-narcotic analgesics, opioid analgesics, calcium channel blockers, muscle relaxants, and systemic corticosteroids.
  • the mechanisms of pain and autonomic dysfunction are poorly understood, the treatments are completely empirical. Between five and ten percent of patients with CRPS develop a chronic form of pain, often with severe disability and extensive use of pain medications. Therefore, there remains a need for safe and effective methods of treating and managing pain.
  • IMMUNOMODULATORY COMPOUNDS A group of compounds selected for their capacity to potently inhibit TNF-a production by LPS stimulated PBMC has been investigated. L.G. Corral, et al, Arm. Rheum. Dis. 58:(Suppl I) 1107-1113 (1999). These compounds, which are referred to as LMiDsTM (Celgene Corporation) or Immunomodulatory Drugs, show not only potent inhibition of TNF- ⁇ but also marked inhibition of LPS induced monocyte ILl ⁇ and IL12 production. LPS induced IL6 is also inhibited by immunomodulatory compounds, albeit partially. These compounds are potent stimulators of LPS induced IL10. Id.

  • Animals are injected with an immunomodulatory compound or vehicle (controls) followed by the injection of formalin into the dorsal surface ofthe paw. The animal is observed to determine the number of times it flinches the injected paw over a period of 60 minutes. This model allows for the evaluation of anti-nociceptive drugs in the treatment of pain. Abbott, F. et al. Pain 60:91-102 (1995). Animals are contained in shoe box cages for the duration ofthe experiment. Formalin (50 ⁇ l; 0.5%) is injected into the dorsal surface ofthe rear, right paw, by placing the needle (28.5G) above the toes and below the ankle and inserting it beneath the surface of the skin. A timer is started immediately after the injection to mark the beginning of phase 1.
  • phase 2 begins. Flinches are counted as in phase 1 for the next 20 minutes.
  • An immunomodulatory compound is administered in an amount of from about 0.10 to about 150 mg/day by oral route up to 24 hrs prior to the formalin test. Animals are repeated in the order they are treated. Immediately following the completion ofthe test periods, animals are euthanized by CO 2 asphyxiation in accordance with IACUC guidelines.
  • Morphine treatment is used to determine the optimal hotplate temperature. Doses of 8 to 10 mg/kg morphine (i.p.) provide a near-maximal anti-nociceptive response in acute pain assays. The apparatus is set to the temperature at which this type of anti-nociceptive response is observed with these doses of morphine (approximately 55°C). An immunomodulatory compound is administered in an amount of from about 0.10 to about 150 mg/day by oral route up to 24 hrs prior to the hot-plate test. When the post-treatment time is elapsed, individual testing of animals is begun. A single animal is placed on the hot plate and a stopwatch or timer is immediately started.
  • the animal is observed until it shows a nociceptive response (e.g., licks its paw) or until the cut-off time of 30 seconds is reached (to minimize tissue damage that can occur with prolonged exposure to a heated surface).
  • the animal is removed from the hot-plate and its latency time to respond is recorded. For animals that do not respond prior to the cut-off time, the cut-off time will be recorded as their response time. Animals are repeated in the order they are treated. Animals are euthanized immediately following the experiment by CO 2 asphyxiation in accordance with IACUC guidelines. Any animal experiencing unanticipated events at any time point throughout this study is evaluated for veterinary intervention. Any animal that cannot recover with standard veterinary care is euthanized immediately by CO 2 asphyxiation in accordance with IACUC guidelines.
  • An immunomodulatory compound is administered in an amount of from about 0.10 to about 150 mg/day by oral route up to 24 hrs prior to the tail flick test in accordance with the IACUC guidelines.
  • post-treatment time is elapsed, individual testing of animals is begun.
  • a single animal is placed on a tail flick apparatus exposing the ventral tail surface to a focused light beam.
  • Response latency is the time from the application of the light until the tail is flicked. The animal is observed until it shows a nociceptive response (e.g., tail flick) or until the cut-off time of 10 seconds is reached (to minimize tissue damage that can occur with prolonged exposure to a heated surface).
  • the animal is removed from the light source, its latency time to respond is recorded and then the animal is euthanized immediately by CO 2 asphyxiation in accordance with IACUC guidelines.

This model is a modification ofthe warm water tail withdrawal model. Ko, M.C. et al, J. of Pharmacol. Exp. Therap. 289:318-385 (1999). Briefly, monkeys sit in a custom made chair in a temperature-controlled room (20-22°C). Their tails are shaved with standard clippers and tail withdrawal latencies are timed in 0.1 second increments up to a maximum of 20 seconds in both 38°C and 42°C water stimuli to provide a baseline.

  • capsaicin patch is fastened to the tail with tape.
  • the patch is removed and tail withdrawal testing in both 38°C and 42°C water stimuli is performed as described above. Allodynia is detected as a decrease in tail withdrawal latency compared to the baseline measurements.
