BACKGROUND OF THE INVENTION

[0003] Age-related macular degeneration (AMD) refers to the chronic, progressive degenerative pathology of the macula that results in loss of central vision. According to the Macula Vision Research Foundation and the National Eye Institute, as many as fifteen million people in the United States suffer from some form of AMD, with similar numbers in Europe and other continents. Neovascular AMD (also revered to as exudative or "wet" AMD) is the leading cause of severe vision loss and blindness in elderly patients over the age of fifty in the industrialized world. In the United States alone, more than 1.5 million people suffer from wet AMD. It is expected that AMD incidence and prevalence will further increase with the ageing population, thus leading to a significant increase in the number of patients with wet AMD in the United States and worldwide.

[0004] Tissue factor (TF) is a cytokine receptor present on vascular endothelial cells. It is an integral membrane glycoprotein with an intracellular terminal domain, a transmembrane domain, and an extracellular binding domain for Factor VII (FVH) and Factor Vila (FVIIa). TF has been implicated in the process of angiogenesis and the inflammatory cascade of cytokine release, both processes in the pathogenesis of neovascular AMD and certain cancers. [0005] Choroidal neovascularization (CNV) is the process in which new blood vessels grow in the choroid layer of the eye, and is associated with wet AMD. Therapies targeting vascular endothelial growth factor (VEGF) are currently the standard of clinical care for wet AMD. However, due to the multifaceted aspects of choroidal neovascularization and AMD pathogenesis, targeting VEGF alone is most likely insufficient to halt the progression of the disease towards the advanced CNV-associated degenerative processes.

[0006] There is an unmet medical need for new therapeutic strategies for choroidal neovascularization and age-related macular degeneration. The present invention addresses this and other needs.

SUMMARY OF THE TNVENTION

[0007] In one aspect, the present invention provides a method for treating wet age-related macular degeneration (AMD) in the an eye of a patient in need thereof, comprising, administering to the patient in a dosing regimen comprising multiple dosing sessions, a pharmaceutical composition comprising an effective amount of an immunoconjugate dimer comprising monomer subunits that each comprise a mutated human factor Vila (fVTIa) protein conjugated to the human immunoglobulin Gl (IgGl) fragment crystallizable (Fc) region, or a portion thereof. In one embodiment, the mutated human fVIIa protein is conjugated to the human IgGl via the hinge region of IgGl. In one embodiment, the immunoconjugate dimer is a homodimer. In another embodiment, the immunoconjugate dimer is a heterodimer. In one embodiment, the immunoconjugate dimer has the amino acid sequence of SEQ ID NO:2 or 3 In a further embodiment, the immunoconjugate dimer has the amino acid sequence of SEQ ID NO: 2. In one embodiment, the immunoconjugate dimer is encoded by SEQ ID NO: 1, 4, or 5.

[0008] In one embodiment of the method for treating wet (AMD), each dosing session comprises intraocular injection e.g., intravitreal injection of the pharmaceutical composition. In another embodiment, each dosing session comprises topical administration of the pharmaceutical composition (e.g., via eye drops).

[0009] The multiple dosing sessions in one embodiment, comprise two or more, three or more, four or more or five or more dosing sessions. In a further embodiment, the time between each dosing session is from about 10 days to about SO days, from about 10 days to about 40 days, from about 10 days to about 30 days or from about 10 days to about 20 days. In a further embodiment, the multiple dosing sessions comprise intravitreal injection of the pharmaceutical composition once every 14 days, once every 28 days, or once every 30 days.

[0010] In one embodiment, the method for treating wet age-related macular degeneration (AMD) comprises administering a pharmaceutical composition comprising an effective amount of the immunoconj ugate dimer, wherein one or both of the monomer subunits comprises a mutated human factor Vila having a substitution of alanine for lysine-341 (e.g., the protein of SEQ ID NO:2) or alanine for serine-344 (e.g, the protein of SEQ ID NO: 3).

[0011] In one embodiment of the method for treating wet AMD in the eye of a patient in need thereof, the patient substantially maintains his or her vision subsequent to the multiple dosing sessions, as measured by losing fewer than 15 letters in a best-corrected visual acuity (BCVA) measurement, compared to the patient's BCVA measurement prior to the multiple dosing sessions. In a further embodiment, the loss of fewer than 15 letters in BCVA is sustained for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about 50 days or at least about 100 days or at least one year after the treatment regimen has concluded. In another embodiment, the patient experiences an improvement in vision subsequent to the multiple dosing sessions, as measured by gaining 15 letters in a best-corrected visual acuity (BCVA) measurement, compared to the patient's BCVA prior to the multiple dosing sessions. In a further embodiment, the improvement in BCVA is sustained for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about 50 days or at least about 100 days or at least one year after the treatment regimen has concluded.

[0012] In one embodiment of the method for treating wet AMD, subsequent to the multiple dosing sessions, or one or more of the dosing sessions, the CNV area is reduced in the eye of the patient, as compared to the CNV area prior to the multiple dosing sessions, or one or more of the dosing sessions (e.g., as measured by fluorescein angiography). In a further embodiment, the CNV area is reduced by at least about 10%, at least about 20% or at least about 30%, at least about 40% or at least about 50%, as compared to the CNV area prior to the multiple dosing sessions, or one or more dosing sessions. [0013] In one embodiment of the method for treating wet AMD in the eye of the patient in need thereof, subsequent to the multiple dosing sessions, or a subset thereof, the retinal thickness of the eye of the patient is decreased as measured by optical coherence tomography (OCT), as compared to the retinal thickness of the eye prior to the multiple dosing sessions, or a subset thereof (e.g., the first dosing session, the first and second dosing session, etc.). The retinal thickness, in one embodiment, is a decreased by at least about 50 μm., at least about 100 μηι, at least about 150μm. , at least about 175 μm., at least about 200 μm., at least about 225 μm., at least about 250 μm., at least about 275 μm. or at least about 300 μηι. The retinal thickness, in one embodiment, is a decreased by at least about 10%, at least about 20% or at least about 30%, as compared to retinal thickness of the eye prior to the multiple dosing sessions, or a subset thereof. The decreased retinal thickness in one embodiment is decreased central retinal subfield thickness (CST), decreased center point thickness (CPT), or decreased central foveal thickness (CFT).

[0014] In one embodiment, during treatment, or upon completion of treatment, neovascularization, e.g., choroidal neovascularization, of the eye of the patient is reversed. In another embodiment, neovascularization, e.g., choroidal neovascularization, of the eye of the patient is inhibited during the treatment regimen, or for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about 50 days or at least about 100 days after the treatment regimen has concluded. In one embodiment, the patient in need of treatment has not been previously treated for wet AMD or choroidal neovascularization. However, in another embodiment, the patient has previously been treated for choroidal vascularization or wet AMD. In a further embodiment, the patient was non-responsive or not properly responsive to the previous treatment. In a further embodiment, the previous treatment for choroidal neovascularization or wet AMD comprises anti-vascular endothelial growth factor (VEGF) therapy, laser therapy or surgery.

[0015] In one embodiment, the method for treating wet age-related macular degeneration (AMD) comprises further administering a neovascularization inhibitor and/or angiogenesis inhibitor to the patient. In one embodiment, the neovascularization inhibitor and/or angiogenesis inhibitor is present in the same composition as the effective amount of the immunoconjugate dimer. However, in another embodiment, the neovascularization inhibitor and/or angiogenesis inhibitor is present in a different composition than the effective amount of the immunoconjugate dimer. In one embodiment, the neovascularization inhibitor and/or angiogenesis inhibitor is a vascular endothelial growth factor (VEGF) inhibitor, a VEGF receptor inhibitor, a platelet derived growth factor (PDGF) inhibitor or a PDGF receptor inhibitor.

[0016] Yet another embodiment of the method for treating wet AMD comprises administering to the patient in a dosing regimen comprising multiple intravitreal dosing sessions, a pharmaceutical composition comprising an effective amount of an immunoconj ugate comprising a mutated human factor Vila (fVIIa) protein conjugated to the human immunoglobulin Gl (IgGl) fragment crystallizable (Fc) region, or a portion thereof, and measuring the intraocular pressure (IOP) in the eye of the patient prior to and subsequent to each intravitreal injection, e.g., via tonometry. In a further embodiment, the method comprises measuring the IOP in the eye of the patient about 20 minutes, about 30 minutes, about 40 minutes, about 50 minutes or about 1 hour after each intravitreal injection.

[0017] In another aspect, the present invention provides a method for inhibiting, preventing or reversing ocular neovascularization in the an eye of a patient in need thereof, comprising, administering to the patient in a dosing regimen comprising multiple dosing sessions, a pharmaceutical composition comprising an effective amount of an immunoconjugate dimer comprising monomer subunits that each comprise a mutated human factor Vila (fVIIa) protein conjugated to the human immunoglobulin Gl (IgGl) fragment crystallizable (Fc) region, or a portion thereof. In one embodiment of this aspect, the mutated human factor Wa comprises a substitution of alanine for lysine-341 or of alanine for serine-344 {e.g., the immunoconjugate of SEQ ID NO: 2). In another embodiment, the ocular neovascularization is associated with (or secondary to) proliferative diabetic retinopathy, wet AMD, retinopathy of prematurity (ROP), or neovascular glaucoma. In a further embodiment, the ocular neovascularization is choroidal neovascularization.

[0018] In one embodiment of the method, after at least one dosing session of the pharmaceutical composition, choroidal neovascularization is inhibited for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about SO days or at least about 100 days after the at least one dosing session. [0019] In the methods for inhibiting, preventing or reversing ocular neovascularization, multiple dosing sessions of the composition can be employed. For example, the pharmaceutical composition comprising the immunoconj ugate dimer in one embodiment is administered two or more, three or more, four or more or five or more times to the patient in need thereof In a further embodiment, the time between each dosing session is from about 10 days to about SO days, from about 10 days to about 40 days, from about 10 days to about 30 days or from about 10 days to about 20 days. In a further embodiment, the multiple dosing sessions comprise intravitreal injection of the pharmaceutical composition once every 14 days, once every 28 days, or once every 30 days.

[0020] In one embodiment, the method for inhibiting, preventing or reversing ocular neovascularization comprises administering a pharmaceutical composition comprising an effective amount of the immunoconj ugate dimer, wherein the mutated human factor Vila comprises a substitution of alanine for lysine-341 (e.g., the protein of SEQ ID NO: 2) or of alanine for serine-344 (e.g., the protein of SEQ ID NO: 3). In one embodiment, the immunoconjugate is encoded by a polynucleotide sequence comprising SEQ ID NO:4 or SEQ ID NO: 5.

[0021] In one embodiment of the method for inhibiting, preventing or reversing ocular neovascularization, the patient substantially maintains his or her vision subsequent to the multiple dosing sessions, as measured by losing fewer than 1 S letters in a best-corrected visual acuity (BCVA) measurement, compared to the patient's BCVA measurement prior to the treatment (i.e., at least one dosing session). In a further embodiment, the loss of fewer than 15 letters in BCVA is sustained for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about SO days or at least about 100 days or at least one year after the treatment regimen (i.e., at least one dosing session) has concluded. In another embodiment, the patient experiences an improvement in vision subsequent to the multiple dosing sessions, as measured by gaining IS letters in a best-corrected visual acuity (BCVA) measurement, compared to the patient's BCVA prior to initiation of treatment. In a further embodiment, the improvement in BCVA is sustained for at least about 10 days, at least about 20 days, at least about 30 days, at least about 40 days, at least about SO days or at least about 100 days or at least one year after the treatment regimen (i.e., at least one dosing session) has concluded.

[0022] In another embodiment of the method for inhibiting, preventing or reversing ocular neovascularization, subsequent to administration of the pharmaceutical composition, as measured by fluorescein angiography, the CNV area is reduced in the eye of the patient, as compared to the CNV area prior to initiation of treatment. In one embodiment of the method for treating wet AMD in the eye of the patient in need thereof, subsequent to at least one dosing session, the retinal thickness of the eye of the patient is decreased as measured by optical coherence tomography (OCT), as compared to the retinal thickness prior to the initiation of treatment with the pharmaceutical composition. The decreased retinal thickness in one embodiment is decreased central retinal subfield thickness (CST), decreased center point thickness (CPT), or decreased central foveal thickness (CFT).

[0023] In some embodiments, administering the immunoconjugate comprises intravenous administration or intratumoral injection.

[0024] In one embodiment, each dosing session comprises the administration of between about 200 μg and about 400 μg of the immunoconjugate dimer. In a further embodiment, each dosing session comprises the administration of about 300 ug of the immunoconjugate dimer.

[0025] In one embodiment, a composition comprising an immunoconjugate dimer, wherein the monomer subunits of the dimer each comprises a mutated human factor Vila (fVIIa) protein conjugated to the human immunoglobulin Gl (IgGl) Fc domain, for use in treating we age- related macular degeneration (AMD) in an eye of a patient in need thereof, wherein the composition is administered to the patient in multiple dosing sessions. In a further embodiment, further to the composition of use, treating the wet AMD comprises preventing, inhibiting, or reversing choroidal neovascularization in the eye of the patient in need of treatment.

[0026] In one embodiment, a composition comprising an immunoconjugate dimer, wherein the monomer subunits of the dimer each comprises a mutated human factor Vila (fVTia) protein conjugated to the human immunoglobulin Gl (IgGl) Fc domain, for use in preventing, inhibiting, or reversing ocular neovascularization in an eye of a patient in need thereof, wherein the composition is administered to the patient in multiple dosing sessions.

[0027] In one embodiment, a composition comprising an immunoconjugate dimer, wherein the monomer subunits of the dimer each comprises a mutated human factor Vila (fVIIa) protein conjugated to the human immunoglobulin Gl (IgGl) Fc domain, for use in reversing tumor neovascularization in a patient in need thereof, wherein the composition is administered to the patient in multiple dosing sessions.

DETAILED DESCRIPTION OF THE INVENTION

[0037] The term "a" or "an" may refer to one or more of that entity, i.e. can refer to plural referents. As such, the terms "a" or "an", "one or more" and "at least one" are used interchangeably herein. In addition, reference to "an element' ' by the indefinite article "a" or "an" does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there is one and only one of the elements.

[0038] Reference throughout this specification to "one embodiment", "an embodiment", "one aspect", or "an aspect" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0039] As used herein, in particular embodiments, the terms "about" or "approximately" when preceding a numerical value indicates the value plus or minus a range of 10%.

[0040] As used herein, "classic CNV means a well-defined CNV area that results in vision that is between 20/250 and 20/400, but may be worse than 20/800.

[0041] As used herein, "occult CNV" means a poorly delineated CNV area that exhibits less leakage than classic CNV, and results in vision that is between 20/80 and 20/200.

Angiogenesis [0042] Pathologic angiogenesis, the induction of the growth of existing blood vessels from the vessels in surrounding tissue, is observed in a variety of diseases, typically triggered by the release of specific growth factors for vascular endothelial cells. Pathologic angiogenesis can result in neovascularization, i.e., the creation of new blood vessels, enabling solid tumor growth and metastasis, causing visual malfunction in ocular disorders, promoting leukocyte extravasation in inflammatory disorders, and/or influencing the outcome of cardiovascular diseases such as atherosclerosis.

[0043] In one aspect of the present invention, methods for treating a patient having a disease associated with neovascularization and/or angiogenesis, such as cancer, rheumatoid arthritis, the exudative ("wet") form of macular degeneration, and/or atherosclerosis are provided. As described herein, administration may be local or systemic, depending upon the type of pathological condition involved in the therapy. As used herein, the term "patienf ' includes both humans and other species, including other mammal species. The invention thus has both medical and veterinary applications. In veterinary compositions and treatments, immunoconj ugates are constructed using targeting and effector domains derived from the corresponding species.

[0044] The present invention is based in part on the observation that normal adult mammalian vasculature is generally in a quiescent state (except for certain processes such as the female reproductive cycle and wound healing), in contrast to the neovasculature that forms in certain disease states such as choroidal neovascularization or a growing tumor which is in an active state of angiogenesis. Therefore, a molecular difference between quiescent and proliferating vascular endothelial cells could serve as a target for the pathologic vasculature. One molecular difference between quiescent and proliferating vascular endothelial cells is that the latter express tissue factor, upon binding of VEGF to its respective cell surface receptor. Tissue factor is a transmembrane receptor that binds plasma factor VH/VIIa to initiate blood coagulation. Because only the vascular endothelial cells that have bound VEGF express tissue factor, a putative target for activated vasculature (e.g., tumor vasculature) is tissue factor expressed on endothelial cells.

[0045] In the aspects provided herein, methods for treating a patient for a disease associated with angiogenesis and/or neovascularization are provided. In one embodiment, the disease associated with neovascularization and/or angiogenesis is wet AMD. In another embodiment, the disease associated with neovascularization and/or angiogenesis is a cancer.

[0046] As used herein, "immunoconjugate" or "immunoconjugates" refer to a conjugate protein such as ICON-1. In some embodiments, an immunoconjugate has as an effector domain an immunoglobulin Fc domain, and said effector domain is conjugated to a targeting domain comprising a mutant form of human factor VII. In some embodiments, an immunoconjugate comprises an Fc domain of a human IgGl immunoglobulin conjugated to a targeting domain comprising a mutant form of factor VII comprising one or two mutations selected from S344A and/or K341A, wherein the immunoconjugate protein binds to tissue factor. In some embodiments, immunoconjugates of the present disclosure include immunoconjugates described in U.S. Patents 7,858,092; 8,388,974, 8,071,104; 7,887,809; and 6,924,359.

[0047] In one aspect provided herein, a composition comprising a fusion protein comprising a mutated FVII protein (targeting domain) conjugated to a human IgGl Fc region (effector domain) are provided. Figure 1 provides the generalized structure of one embodiment of an immunoconjugate that can be administered by the methods provided herein. The mutated Factor Vila domain (also referred to as the TF targeting domain), in the aspects provided herein, binds tissue factor with high affinity and specificity, but does not initiate coagulation, or minimizes coagulation normally associated with tissue factor binding. The IgGl Fc domain (also referred to as the effector domain) triggers a cytolytic response against cells which bind the immunoconjugate, by the natural killer (NK) cell and complement pathways. In one embodiment, the IgGl Fc effector domain comprises both the CH2 and CH3 regions of the IgGl Fc region.

[0048] Table 1: Description of Sequences

[0049] The reaction between FVlIa and TF is species-specific (Janson et al., 1984; Schreiber et al., 2005; Peterson et al., 2005): murine FVII appears to be active in many heterologous species including rabbit, pig and human, whereas human FVIIa is only appreciably active in human, dog, rabbit and pig. Conversely, the human IgG Fc domain is active in both humans and mice. Accordingly, depending on the patient, the immunoconjugate is constructed using targeting and effector domains derived from the corresponding species, or from a species that is known to be active in the patient For example, in the human treatment methods provided herein, the mutated tissue factor targeting domain is derived from human Factor Vila conjugated to an effector domain comprising the Fc region of a human IgGl immunoglobulin. For example, in one embodiment, the immunoconjugate is a protein of SEQ ID NO: 2. In a further embodiment, the immunoconjugate is a protein of SEQ ID NO: 3. In one embodiment, the immunoconjugate is encoded by the mRNA sequence of SEQ ID NO: 1, 4, or 5.

[0050] In one embodiment, the immunoconjugate described herein comprises two protein chains, each comprising a targeting domain joined to an effector domain via a linker or hinge region. In a further embodiment, the linker or hinge region is naturally occurring, and in one embodiment, is of human origin. The hinge region of an IgGl immunoglobulin, for example the hinge region of the human IgGl immunoglobulin, in one embodiment, is used to link the targeting domain to the effector domain. In one embodiment, the hinge region of IgGl includes cysteine amino acids which form one or more disulfide bonds between the two monomer chains (e.g., as depicted in Figure 1).

[0051] In one embodiment, the immunoconjugate is a homodimer. However, in another embodiment, the immunoconjugate is a heterodimer, for example, an immunoconjugate comprising two monomers each having a targeting domain of a different amino acid sequence, but the same effector domains. The amino acid sequences of the two targeting domains, in one embodiment, differ by one amino acid, two or more amino acids, three or more amino acids or five or more amino acids. In one embodiment, each monomer subunit comprises an IgGl hinge region that links the targeting region and effector region of the immunoconjugate, and the monomer subunits of the immunoconjugate heterodimer or the immunoconjugate homodimer are linked together via a disulfide bond between IgGl hinge regions.

[0052] In one embodiment, the molecular weight of the immunoconjugate provided herein is from about 150 kDa to about 200 kDa. In another embodiment, the molecular weight of the immunoconjugate is about 1S7 kDa or 1S7 kDa. For example, the immunoconjugate in one embodiment is the immunoconjugate having the amino acid sequence set forth in SEQ ID NO: 2, also referred to herein as "hl-conl" or "ICON-l" In another embodiment, the immunoconjugate has the amino acid sequence set forth in SEQ ID NO: 3.

[0053] As provided throughout, in embodiments described herein, an immunoconjugate comprising a tissue factor targeting domain comprising a mutated Factor Vila domain is provided. The targeting domain comprises a mutated Factor Vila that has been mutated to inhibit initiation of the coagulation pathway without reducing binding affinity to tissue factor. In one embodiment, the mutation in Factor Vila is a single point mutation at residue 341. In a further embodiment, the mutation is from Lys341 to Ala341. However, other mutations that inhibit the coagulation pathway are encompassed by the immunoconj ugates provided herein. The effector domain of the immunoconj ugates provided herein, in one embodiment, mediates both complement and natural killer (NK) cell cytotoxicity pathways.

Immunoconjugate Production

[0054] In some embodiments, methods of producing the immunoconjugate include expression in mammalian cells such as BHK cells. In further embodiments, cell lines may include HEK 293, CHO, and SP2/0. Immunoconjugates may be generated by mammalian expression of the expression constructs. In some embodiments, the immunoconjugates are produced as fusion proteins (FVTi-Fc) or produced as chemical conjugates.

[0055] In some embodiments, the immunoconjugate is post-translationally modified. Post- translational modification includes: myristoylation, glypiation, palmitoylation, prenylation, lipoylation, acylation, alkylation, butrylation, gamma-carboxylation, glycosylation (N- glycosylation, O-glycosylation, fucosylation, and mannosylation), propionylation, succinylation, and sulfation.

Administering the Immunoconiugate

[0056] Administration methods encompassed by the methods provided herein include intravitreal injection, suprachoroidal injection, topical administration (e.g., eye drops), intravenous and intratumoral administration. In another embodiment, administration is via intravenous, intramuscular, intratumoral, subcutaneous, intrasynovial, intraocular, intraplaque, or intradermal injection of the immunoconjugate or of a replication-deficient adenoviral vector, or other viral vectors carrying a cDNA encoding a secreted form of the immunoconjugate. In one embodiment, the patient in need of treatment is administered one or more immunoconjugate dimers via intravitreal, intravenous or intratumoral injection, or injection at other sites, of one or more immunoconjugate proteins. Alternatively, in one embodiment, a patient in need of treatment is administered one or more immunoconjugate dimers via intravenous or intratumoral injection, or injection at other sites, of one or more expression vectors carrying a cDNA encoding a secreted form of one or more of the immunoconjugate dimers provided herein. In some embodiments, the patient is treated by intravenous or intratumoral injection of an effective amount of one or more replication-deficient adenoviral vectors, or one or more adeno-associated vectors carrying cDNA encoding a secreted form of one or more types of immunoconjugate proteins.

[0057] As used herein, "effective amount" or "therapeutically effective amount" means a level or amount of a therapeutic agent needed to treat a condition or disease of the present disclosure, or the level or amount of a therapeutic agent that produces a therapeutic response or desired effect in the subject to which the therapeutic agent was administered; wherein a therapeutic agent is an immunoconjugate of the present disclosure. Thus, a therapeutically effective amount of a therapeutic agent, such as an immunoconjugate of the present disclosure, is an amount that is effective in reducing one or more symptoms of angiogenesis and/or neovascularization, as well as various forms of AMD.

[0058] As used herein, "pharmaceutical composition" means a composition comprising a therapeutic agent. [001] As used herein, "treatment", "treating", and the like, mean the following actions: (i) preventing a particular disease or disorder from occurring in a subject who may be predisposed to the disease or disorder but has not yet been diagnosed as having it; (ii) curing, treating, or inhibiting the disease, i.e., arresting its development; or (iii) ameliorating the disease by reducing or eliminating symptoms, conditions, and/or by causing regression of the disease

[0059] In one embodiment, a method of intravitreal injection is employed. In a further embodiment, aseptic technique is employed when preparing the immunoconjugate dimer for injection, for example, via the use of sterile gloves, a sterile drape and a sterile eyelid speculum (or equivalent). In one embodiment, the patient is subjected to anesthesia and a broad-spectrum microbicide prior to the injection.

[0060] In one embodiment, intravitreal injection of one or more of the immunoconjugate dimers provided herein, for example the immunoconjugate dimer of SEQ ID NO: 2 is prepared by withdrawing the vial contents of the immunoconjugate dimer composition solution through a 5- micron, 19-guage filter needle attached to a 1-cc tuberculin syringe. The filter needle in a further embodiment, is then discarded and replaced with a sterile 30-gauge x ½-inch needle for the intravitreal injection. The contents of the vial are expelled until the plunger tip is aligned with the line on the syringe that marks the appropriate dose for delivery.

[0061] In one method of ocular injection, e.g., intravitreal or suprachoroidal injection, prior to and/or after the injection, the patient is monitored for elevation in intraocular pressure (IOP). For example, in one embodiment, prior to and/or after the ocular injection, the patient is monitored for elevation in IOP using tonometry. In another embodiment, the patient is monitored for increases in IOP via a check for perfusion of the optic nerve head immediately after the injection. In one embodiment, prior to ocular injection of one of the immunoconjugate dimers provided herein, for example about 20 minutes, about 30 minutes, about 40 minutes, about 50 minutes or about 1 hour prior to the ocular injection, the patient is monitored for elevation in IOP. In another embodiment, after ocular injection of one of the immunoconjugate dimers provided herein, for example, about 10 minutes, about 20 minutes, about 30 minutes, about 40 minutes, about SO minutes or about 1 hour after the intraocular injection, the patient is monitored for elevation in IOP. In one embodiment, the patient's IOP is substantially the same prior to intraocular injection of an immunoconjugate dimer, as compared to after intraocular injection of the immunoconjugate dimer. In one embodiment, the patient's IOP varies by no more than 10%, no more than 20% or no more than 30% after intraocular injection, as compared to prior to intraocular injection (e.g., intravitreal injection).

[0062] The treatment methods provided herein in one embodiment, comprise a single administration of one of the immunoconjugate dimers provided herein (e.g., an immunoconjugate of SEQ ID NO: 2 or 3). However, in another embodiment, the treatment methods provided herein comprise multiple dosing sessions.

[0074] In cancer treatments, the immunoconjugate dimer is used for treating a variety of cancers, particularly primary or metastatic solid tumors, including melanoma, renal, prostate, breast, ovarian, brain, neuroblastoma, head and neck, pancreatic, bladder, endometrial and lung cancer. In one embodiment, the cancer is a gynecological cancer. In a further embodiment, the gynecological cancer is serous, clear cell, endometriod or undifferentiated ovarian cancer. The immunoconjugate dimer in one embodiment is employed to target the tumor vasculature, particularly vascular endothelial cells, and/or tumor cells. Without wishing to be bound by theory, targeting the tumor vasculature offers several advantages for cancer immunotherapy with one or more of the immunoconjugate dimers described herein, as follows, (i) some of the vascular targets including tissue factor should be the same for all tumors; (ii) immunoconj ugates targeted to the vasculature do not have to infiltrate a tumor mass in order to reach their targets; (iii) targeting the tumor vasculature should generate an amplified therapeutic response, because each blood vessel nourishes numerous tumor cells whose viability is dependent on the functional integrity of the vessel; and (iv) the vasculature is unlikely to develop resistance to an immunoconjugate, because that would require modification of the entire endothelium layer lining a vessel. Unlike previously described antiangiogenic methods that inhibit new vascular growth, immunoconjugate dimers provided herein elicit a cytolytic response to the neovasculature.

EXAMPLES

[00145] The present invention is further illustrated by reference to the following Examples. However, it should be noted that these Examples, like the embodiments described above, are illustrative and are not to be construed as restricting the scope of the invention in any way.

Example 1 - Evaluation Of hl-conl In in vitro Thrombin Generation Assays

[00146] The effect of hl-conl (SEQ ID NO:2) in a thrombin generation assay in plasma was tested. Specifically, the effect of hl-conl on thrombin generation in plasma in a tissue factor initiated reaction using a thrombogram (CAT-like) assay (Hemker et al. 2002. Pathophysiol. Haemost Thromb. 32, pp. 249-253; Mann et al. 2007. J. Thromb Haemost. 5, pp. 2055-2061, each incorporated by reference herein in its entirety for all purposes) was evaluated. For the CAT-like assays, multidonor human citrate plasma from healthy individuals, human FVII- deficient plasma and normal rabbit citrate plasma were used. Thrombin (also referred to as Factor Ha, or activated blood coagulation factor Π) generation was initiated either with human relipidated TF (in human plasma) or with rabbit relipidated TF (in rabbit plasma).

[00147] hl-conl was maintained frozen at -70 °C until use. Each sample included 3.0 mg hl-conl/mL in formulation buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaCl₂, 25 mM Arginine, 0.01% Tween 80, pH 7.4).

[00148] Human plasma FVIIa in 50% glycerol was purchased from Haematologic Technologies, Inc., 57 River Road, Essex Junction, VT 05452. It was stored at -20 °C until use. Before use, it was diluted to 10 nM in the formulation buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaC12, 25 mM Arginine, 0.01% Tween 80, pH 7.4).

[00149] Spectrozyme FXa (#222), lipidated recombinant human TF reagent (Catalog #4500L) and lipidated recombinant rabbit TF were purchased from American Diagnostica, Inc. (Stamford, CT), pooled normal human plasma (Lot #ER 11-020711) and rabbit plasma (Lot #26731) were purchased from Innovative Research Novi, MI 48377), congenital FVTi-deficient plasma (Catalog #0700) was purchased from George King Bio-Medical, Inc. (Overland Park, KS) and human factor X (hFX) (#HCX-0050) and Phe-Pro-Arg-chloromethylketone (FPRck; Catalog #FPRCK-01), corn trypsin inhibitor (CTI; Catalog #01-01) were purchased from Haematologic Technologies, Inc (Essex Junction, VT, USA). Fluorogenic substrate Z-Gly-Gly- Arg-AMC HC1 was purchased from Bachem (Torrance, CA) and ethylenediaminetetraacetic acid disodium salt dihydrate (EDTA; #E5134), NaCl (#S7653) and HEPES (#H3375) were purchased from Sigma (St. Louis, MO). HBS buffer, pH 7.4 contained 150 mM NaCl, 2 mM CaCh and 20 mM HEPES.

[00150] Active site inhibited FVIIa (FVUai) was produced in house. 1, 2-Dioleolyl-sn- Glycero-3-Phospho-L-Serine (PS; #840035) and 1, 2-DioleoyJ-sn-Glycero-3-Phosphocholine (PC; #850375) were purchased from Avanti Polar Lipids, Inc. (Alabaster, AL, USA). Phospholipid vesicles (PCPS) composed of 25% PS and 75% PC were prepared as described in Higgins and Mann 1983, incorporated by reference herein in its entirety for all purposes. Extrinsic FXase

[00151] Lipidated recombinant human TF (0.1 nM) was incubated with either 5 nM plasma FVHa or 5 nM hi- con 1 or mixture of both (each at 5 nM) and 100 μΜ PCPS for 10 min at 37 °C. FX (4 uM) was added and at selected time points (0-5 min.) 10 μL aliquots of the reaction mixture were quenched into 170 HBS-0.1% PEG-20 mM EDTA. Twenty μL of Spectrozyme FXa (0.2 mM) was added and the rate of substrate hydrolysis was measured as an increase in absorbance at 40S nm (mOD/min).

Thrombin generation (CAT -like) assay

[00152] Corn trypsin inhibitor (CTT) at a final 0.1 mg/mL concentration was added to citrate plasma and 80 μΐ, of this plasma was transferred into Immulon® 96-well plate (Thermo Electron Co., Waltham MA). When desired, hl-conl, plasma FWa and FVIIai were added at selected concentrations. Twenty μL of 5 pM TF and 20 μΜ PCPS mixture (both concentrations final) were added to CTI-plasma and incubated for 3 min. Thrombin generation was initiated by the addition of 20 of 2.5 mM ZGly-Gly- Arg AMC · HC1 in HBS containing 0.1 M CaCl₂. Final concentration of substrate was 416 μΜ and that of CaCl₂ was 15 mM Thrombin generation curves were generated using Thrombinoscope BY software.

Results

Comparison of hl-conl with plasma FVIIa in the extrinsic FXase

[00153] FXa-generating efficiency of two forms of FVIIa and of their mixture was determined in a chromogenic assay, hl-conl was less active than plasma FVIIa. Activity of hl- conl was 18% of that observed for plasma FVIIa. When both proteins were added at equimolar (5 nM) concentration, the rate of FXa generation in the middle between the rates observed for individual proteins, indicating that hl-conl competes with plasma FVIIa for the limited amount of TF (Figure 2). These data also suggest that hl-conl has similar affinity for TF as plasma FVIIa. Thrombin generation in normal human plasma: the effect of FVHai

[00154] It was hypothesized that due to the low activity of the hl-conl tissue factor (TF) complex in the extrinsic FXase, hl-conl could act as an inhibitor by binding TF into an inefficient complex and preventing formation of an efficient complex between plasma FVHa and TF. To test this hypothesis, the effect of a known inhibitor of coagulation, i.e., active site inhibited FVHa (Kjalke et al. 1997), on thrombin generation in normal human plasma was evaluated. FWai at 1 nM concentration had no effect on thrombin generation initiated with lipidated human TF (Figure 3). However at 10 nM, FVHai prolonged the lag phase of thrombin generation and significantly suppressed both the maximum rate of thrombin generation and the maximum levels of thrombin produced. No thrombin generation was observed in the absence of TF.

Thrombin generation in normal human plasma: the effect of hl-conl

[00155] hl-conl was titrated into normal human plasma initiated with TF to generate thrombin. Varying concentrations of hl-conl was used, however even at extremely high hl-conl concentrations (1 μΜ), no inhibition of thrombin generation was observed (Figure 4).

Thrombin generation in congenital FVII-deficient human plasma

[00156] No thrombin generation was observed upon the addition of lipidated human TF to congenital FVII-deficient plasma, indicating that there no detectable functional FVTIa in that plasma (Figure 5). An addition of 0.1 nM plasma FVTIa together with TF produced thrombin generation profile slightly lower than that observed in normal human plasma. An addition of 0.1 nM hl-conl alone in the presence of TF led to the initiation of thrombin generation, however the process was significantly delayed and suppressed (Figure 5). This result was consistent with the observation of low hl-conl activity in the extrinsic FXase. The addition of both plasma FVTIa and hl-conl at equimolar concentrations (0.1 nM) did not impair thrombin generation initiated with plasma FVTIa alone. Thrombin generation in normal rabbit plasma

[00157] Thrombin generation in rabbit plasma was initiated with lipidated rabbit TF. The addition of 1 nM hl-conl to this plasma had no pronounced effect on thrombin generation (Figure 6). Similarly, no pronounced effect was observed when 10 nM FVIIai was added. At higher hl-conl concentrations (10-1000 nM) some suppression in thrombin generation was observed. However the control experiment with no TF added led to thrombin generation, suggesting an endogenous presence of TF.

Thrombin generation in centrifueed rabbit plasma

[00158] After centrifugation of rabbit plasma, an endogenous thrombin generating activity did not disappear completely, but was significantly decreased (Figure 7). No suppression in TF- triggered thrombin generation was observed when 10 nM FVIIai was added. Similarly, no suppression was observed when 1-100 nM hl-conl was added and only a limited decrease in thrombin generation was observed when high concentration (1 μΜ) hl-conl was added (Figure 7). These data indicate that at physiologically-relevant concentrations hl-conl does not compete for rabbit TF with rabbit FVHa.

Conclusions

[00159] hl-conl does not compete with plasma FVHa for TF in the citrate plasma environment hl-conl has no pronounced (if any) effect on thrombin generation either in human plasma initiated with human TF or in rabbit plasma initiated with rabbit TF. It is not likely that hl-conl would cause bleeding or thrombotic complications.

Example 2 - Effects of Treatment With hl-conl on Choroidal Neovascularization in the Pig

[00160] In this study, hl-conl activity in a porcine wet AMD model (Kiilgaard et al., 2005. Acta. Ophthalmol. Scand. 83, pp. 697-704, incorporated by reference herein in its entirety for all purposes) and the optimal dose for the activity was examined. Additionally, the safety of hl-conl when administered by intravitreal injection was determined.

[00161] In this study intravitreal injection of hl-conl was demonstrated to result in the destruction of established laser-induced CNV in this porcine model. The injections of hl-conl were well tolerated and the effects were dose-related, with and EDso of 13.5 μg/ dose A major breakdown product of hi- con 1 (lOOkDa) was tested and was also well-tolerated and effective with an EDso of 16.2 μg/ dose

Test Articles hi- con 1

[00162] hl-conl was provided by Laureate Pharma Inc., 201 E. College Ave, Princeton, NJ, 08540. hl-conl was maintained frozen at -70 °C until use: Lot PURIC1 080402 (SEC Fr 10- 14), two vials each containing 200 μL at 2.0 mg/mL, 1.0 mg/mL, 0.5 mg/mL and 0.25 mg/mL in formulation buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaCh, 25 mM Arginine, 0.01% Tween 80, pH 7.4).

100 kD Fragment of hl-conl

[00163] The following samples of the 100 kD fragment of hl-conl were provided by Laureate Pharma Inc. 201 E. College Ave, Princeton, NJ, 08540. The fragment was maintained frozen at -70 °C until use: Lot PURIC1 080402 (SEC Fr 15), two vials each containing 200 μL at 2.0 mg/mL, 1.0 mg/mL, 0.5 mg/mL and 0.25 mg/mL in formulation buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaCh, 25 mM Arginine, 0.01% Tween 80, pH 7.4).

Control Article

[00164] The formulation buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaCh, 25 mM Arginine, 0.01% Tween 80, pH 7.4) was used as the vehicle control.

Test Animals

[00165] Two studies were conducted, each with groups of five (one group per test article) Yucatan miniature pigs (Sus scrofa), 10-12 weeks old, each weighting approximately 20 kilograms were bought from Professional Veterinary Research (Brownstown, IN, USA). Husbandry

[00166] Each pig was maintained in a separate cage within a communal environment that housed four pigs. The lighting was computer controlled and set for a 6am to 6pm cycle. The temperature average was 70-72 ° F, with a variation of +/- 1 degree. Humidity was kept between 30 and 70%, with average humidity equal to 33%. The animals were evaluated by the large animal husbandry supervisor and a licensed veterinary technician on arrival and a licensed veterinary technician once weekly until they were euthanized. A veterinarian evaluated the animals to determine if there were any abnormalities or concerns. The animals were quarantined for about 1 week prior to experiments.

Feed and Water

[00167] Daily feed and water were provided to the miniature pigs. They were bedded on hay that served as a feed supplement The feed was Purina #5084, Laboratory Porcine Grower Diet, Manufactured by Purina Mills, LLC, 555 Maryville University Drive, Suite 500, St Louis, Missouri 63141, and fed at 2% body weight per day. The water was 0.5 micron filtered tap water. It was not routinely analyzed for contaminants except by the water company and reports are reviewed annually.

Justification of Species

[00168] hl-conl has limited cross-species activity and the pig is one of the few laboratory animal species in which it is active. The vitreous cavity of the pig is approximately 3 mL, allowing intravitreal injection of reasonable volumes of test article. The pig eye has retinal vascular similarities to humans in addition to several cone-dominant regions of the retina that are similar to the human macula.

Methods

Laser-Induced Choroidal Neovascularization

[00169] Under general anesthesia, the pupils of the animals were dilated with 1% tropicamide and 2.5% phenylephrine. An indirect ophthalmoscope with a double-frequency YAG laser (532 nm) was used to deliver 74 spots per eye using a 2.2 D lens and the following laser parameters: laser power 1000-1500 mW, duration 0.1 seconds, and repetition rate 500 msec. The laser treatment was designed to yield a microrupture of the Bruch's membrane, generating CNV at 60-70% of the laser spots within two weeks (Bora et al., 2003, incorporated by reference herein in its entirety for all purposes).

Study Design

[00170] The study design is summarized in Table 3 below.

[00171] Choroidal neovascularization was induced on Day 0 in both eyes of two groups of 5 pigs. On Day 10, 100 μL of solutions of hl-conl (Study 1) or its 100 kD fragment (Study 2) at 0.25, 0.5, 1.0 or 2.0 mg/mL were administered by intravitreal injection into both eyes of the pigs as shown in Table 3. On Day 10, 100 μL of formulation buffer was administered by intravitreal injection into both eyes of the control pigs.

Test and Control Articles Administration

[00172] The animals were anesthetized with a mixture of ketamine hydrochloride (40 mg/kg) and xylazine hydrochloride (10 mg/kg). Injections were administered using a strict sterile technique, which involved scrubbing the lids with a 5% povidone-iodine solution and covering the field with a sterile eye drape. A sterile lid speculum was used to maintain exposure of the injection site. All injections were performed 2 mm from the limbus through the pars plana, using a 30- gauge needle on a 1 mL tuberculin syringe. After injection, a drop of 2% cyclopentolate and antibiotic ointment was placed in the eye. The animals were examined daily for signs of conjunctival injection, increased intraocular pressure, anterior uveitis vitritis, or endophthalmitis, and were sacrificed on Day 14. Terminal Procedures

[00173] On Day 14, the pigs were anesthetized with an 8: 1 mixture of ketamine and xylazine and perfused through the ear vein with 10 mL PBS containing 3 mg/mL fluorescein- labeled dextran with an average molecular weight 2 x 10⁶ (Sigma, St. Louis, MO, USA). The eyes were enucleated and four stab incisions were made at the pars plana followed by fixation in 4% paraformaldehyde for 12 hours at 4 °C. The cornea and the lens were removed, and the neurosensory retina was dissected from the eyecup and four radial cuts were made from the edge of the eyecup to the equator. The choroid-retinal pigment epithelium (RPE) complex was separated from the sclera and flatmounted on a glass slide in Aquamount with the inner surface (RPE) facing upwards. Flat mounts were stained with a monoclonal antibody against elastin (Sigma) and a Cy3-conjugated secondary antibody (Sigma) and examined with a confocal microscope (Zeiss LSM510, Thornwood, NY, USA). The vasculature, filled with dextranconjugated fluorescein, stained green and the elastin in the Bruch's membrane stained red. The level of the Bruch's membrane was determined by confocal microscopy using the intense red signal within a series of z-stack images collected at and around the laser spot. The presence of CNV was indicated by the branching linear green signals above the plane of Bruch's membrane. Absence of CNV was defined under very stringent criteria as the total absence of green fluorescence in the vessels in the spot (see Tezel et al., 2007. Ocular Immunol Inflamm 15, pp. 3-10.

Statistical Analysis

[00174] The percentage of laser spots with CNV at different doses of hl-conl or its 100 kD fragment was compared pair wise by a chi-square test The results were plotted against the hl-conl dose to derive the best-fit curve, which was used to calculate the dose of hl-conl that reduces the fraction of laser spots with CNV by 50% (ED50). A confidence level of p <0.05 was considered to be statistically significant. Results

Effects of Intravitreal Treatment with hl-conl on CNV

[00175] Choroidal neovascularization developed in 71.9 ± 5.8% of the laser spots in control eyes. A single intravitreal injection of hl-conl on Day 10 in pig eyes (n = 2 at each dose) significantly reduced subretinal CNV on Day 14 at all doses tested, i.e., 25-200 ug, Table 4; Figure 8). The inhibitory effect of hl-conl fit well to a 5-parameter Sigmoidal Weibull curve. The dose causing a 50% decrease in the yield of CNV (ED50) was 13.5 μg.

Effects of Intravitreal Treatment with 100 kD fragment of hl-conl on CNV

[00176] Choroidal neovascularization developed in 85.6 ± 4.1% of the laser spots in control eyes. A single intravitreal injection of the 100 kDa fragment of hl-conl on Day 10 in pig eyes (n = 2 at each dose) significantly reduced subretinal CNV on Day 14 at all doses tested, i.e., 25-200 pg, Table 4, Figure 9). The inhibitory effect of hl-conl fit well to a 5-parameter Sigmoidal Weibull curve. The dose causing a 50% decrease in the yield of CNV (ED50) was 16.2 μ₈.

[00177] Intravitreal injection of hl-conl and its 100 kD fragment at doses from 25-200 μg caused significant regression of pre-existing laser-induced CNV 4 days after the injections were administered. The response of the lesions to the injections was clearly dose-related with EDso doses of 13.5 and 16.2 ug, respectively. These results indicate that the specific activity of the 100 kD fragment of hl-conl is similar to that of the intact molecule. Doses greater than 100 ug had very little additional decrease in CNV; thus, the efficacious dose in this model is < 100 pg.

Example 3 - Tissue Cross-Reactivity Study of hl-conl With Normal Human Tissues

[00178] In this study, the binding of hl-conl to normal human tissues was assessed using standard immunohistochemistry (IHC) techniques, in a standard tissue cross-reactivity (TCR) study. The study was performed utilizing a single batch of biotinylated hl-conl for IHC staining of normal, as well as positive and negative control human tissues. A positive staining result is indicative of potential toxicities associated with administration of hl-conl to humans in vivo.

[00179] In this model, tissue staining was observed only in the positive control colon carcinoma tumor. All other normal human tissues showed no immunoreacti vity . These findings indicate that hl-conl binding is specific to abnormal tissue, with no binding to normal tissues observed. Example 4 - Evaluation of the Binding of hi- con 1 to Lipidated Tissue Factors

[00180] To allow for cross species comparison, a Biacore study of the kinetics of binding of hl-conl and hFvTIa to human lapidated TF (hTF) and rabbit lipidated TF (rTF) was conducted.

[00181] As described in detail below, hl-conl and hFVIIa both bound with high and approximately equal affinity to lapidated hTF.

Materials and Methods

[00182] Lipidated rabbit tissue factor (rTF; Product # 4520L; Lot # 051017) purchased from American Diagnostica. Lipidated human tissue factor (hTF; Lot FTL105HO1) supplied by Marin Biological Laboratories, 378 Bel Marin Keys, Novato, CA 94949.

[00183] hl-conl ; 1 ml; 100 pg/ml; MW 157 kDa

[00184] Human FVHa; Lot # A09050525 (Fitzgerald); 1.01 mg/ml; 40 μL/vial; MW 50 kDa

Equipment: Biacore 3000; CM5 Sensor chip

[00185] The GE procedure for proteoliposome immobilization (amine coupling) protocol was used to coat PS/PC/rTF on flow cell 2, and PS/PC/hTF on flow cell 3. Flow cells were equilibrated with running buffer (15 mM Hepes, 150 mM NaCl, 5 mM CaC12, 25 mM Arginine, 0.01% Tween 80, pH7.4) at a flow rate of 5 μΙ7πι.η. Kinetic analyses were performed at 37 °C by flowing consecutively increasing concentrations of each analyte (0-10 nM) in the running buffer (15 mM HEPES, 150 mM NaCl, 5 mM CaC12, 25 mM Arginine, 0.01% Tween 80, pH 7.4) over the sensor chip for 5 min followed by a 10 min dissociation period at a flow rate of 30 μL /min in parallel.

[00186] Analyte binding to the lipidated TF was determined by subtracting the RU values noted in the reference flow cell 1 from flow cell 2 and 3. Binding of analytes to the TFs was monitored in real time to obtain on (ka) and off (kd) rates. The equilibrium dissociation constant (KD) was calculated from the observed ka and kd. [00187] The chips were regenerated with 3 min pulses of 10 mM EDTA in HEPES buffer (20 mM HEPES, 150 mM NaCl, pH 7.4).

[00188] Capture of rTF to the chip - Flow cell 2 was coated with rabbit TF (>Resonance Units [RU] 10,000) by amine coupling. Flow cell 3 was coated with human TF (>RU 8,000) by amine coupling.

Determination of the amount of test lipands (RU) to be captured on the chip

[00189] In this experiment, the desired level of RM_HX for the measurement of ligand- analyte interaction was based on the value determined by a previous experiment where rTF captured at 10,000 Resonance Units ("RU') gave binding of hl-conl with RMax of 15 RU and hTF captured at 8,000 RU gave binding of hl-conl with RMax of 10RU. The amount of the analyte to be captured on the chip depended on the molecular weights of the interacting proteins. It is determined by the following formula:

[00190]

[00191] MW_A is the molecular weight of the analyte (157 kDa for hl-conl, 50 kDa for hFVna, and 150 kDa for IgGl).

[00192] MWL is the molecular weight of the ligand, in this assay it is expected to be very large (multiple of 35 kDa).

Flow rate of the antibody solution

[00193] The flow rate used for capturing the ligand was 10 μΙ7πι.η. [00194] For kinetics analysis, the flow rate of 30 uIJmin. was used. Kinetic analysis

[00195] Based on the saturation concentration of the analyte, binding analysis was performed using saturating analyte concentrations of 0-500 nM for rabbit TF and 0-50 nM for human TF. Chi squared (χ²) analysis was carried out between the actual sensorgram and the calculated on- and off-rates to determine the accuracy of the analysis. [00196] χ² value up to 2 is considered significant (accurate) and below 1 is highly significant (highly accurate).

Results

[0019η The Biacore assay results are provided in Table 6 below.

[00198] As shown in Table 7 below, hl-conl and hFVTia both bound with high, and approximately equal, affinity to lipidated hTF. Both ligands also bound to lipidated rTF with approximately 10-fold lower affinities.

Example S - Randomized. Double-Masked. Multicenter. Active-Controlled Study Evaluating hl-conl in Patients With CNV Secondary to Age-Related Macular Degeneration

[00199] In this study, the safety of intravitreal injections of hl-conl, administered as monotherapy or in combination with ranibizumab (LUCENTIS) compared to ranibizumab monotherapy in patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) is assessed.

[00200] Additionally, the biological activity and pharmacodynamics effect of hl-conl, administered as monotherapy or in combination with ranibizumab (LUCENTIS) compared to ranibizumab monotherapy is assessed.

[00201] The study presented in this example is a randomized, double-masked, multicenter, active-controlled study. Patients enrolled in this study are naive to treatment for CNV. Patients are randomly assigned to one of the following three treatment arms in the selected study eye in a 1:1:1 ratio:

• hl-conl monotherapy (0.3 mg) + sham injection

• ranibizumab monotherapy (0.S mg) + sham injection

• hl-conl (0.3 mg) + ranibizumab (0.5 mg) combination therapy

[00202] Randomization is stratified by best-corrected visual acuity (BCVA) letter score in the study eye at baseline (<54 letters versus >55 letters) and by study site.

[00203] Patients receive up to two intravitreal injections at each injection visit In order to maintain the study mask among the treatment arms, a sham injection is employed in patients receiving monotherapy.

[00204] Patients are administered intravitreal injections in the study eye once every four weeks at months 0, 1 and 2. As of Month 3 (at Months 3, 4 and 5) patients are retreated according to their assigned treatment arm, based on their individual observed treatment response. The masked Investigator uses the following retreatment criteria (based on the category of individual patient response) to determine if treatment is required at these visits: • Loss of >5 letters of BCV A due to AMD compared to the previous scheduled visit.

• Independent of BCVA change, any anatomical evidenced of increased CNV activity (e.g., new or increased fluid and/or leakage, hemorrhage) compared to the previous scheduled visit.

• No BCVA change compared to Baseline (Visit 2), but there is anatomical evidence of persistent CNV activity (e.g., same persistent fluid and CST compared to Baseline.

[00205] Rescue treatment with 0.S mg of ranibizumab is administered to the study eye as an add-on therapy at any time during the 6-month treatment and follow-up period if either of the following conditions occur:

• Loss of >15 letters of BCVA due to AMD compared to Baseline (Visit 2).

• Loss of >10 letters from baseline (Visit 2) of BCVA due to AMD that is confirmed at two consecutive visits. Patients with a loss of >10 letters compared to baseline are requested to return within 7 days or as soon as possible for additional follow up at an unscheduled visit.

[00206] The masked physician will make the determination if rescue treatment is needed according to the above criteria.

[00207] If rescue treatment is administered to the study eye during a scheduled injection visit, to ensure that the study masking is maintained, the unmasked physician administers rescue treatment and the patient's scheduled study treatment/re-treatment is as follows.

• hl-conl monotherapy arm: hl-conl (0.3 mg) + rescue therapy (0.5 mg ranibizumab).

• ranibizumab monotherapy arm: ranibizumab (0.5 mg) + sham injection.

• combination therapy: hl-conl (0.3 mg) + ranibizumab (0.5 mg).

[00208] If rescue treatment is administered to the study eye at an unscheduled visit, the unmasked physician administers rescue treatment as requested. [00209] If rescue treatment is administered to the study eye, the patient continues with the study visit schedule for the next visit in accordance with the protocol and continues receiving study treatment according to the assigned randomization arm.

[00210] Safety is evaluated by tracking of adverse events, clinical laboratory tests (serum chemistry, hematology and coagulation), vital signs measurements, abbreviated physical examinations, slit-lamp biomicroscopy, intraocular pressure (IOP) and dilated ophthalmoscopy. Pharmacodynamic and biological activity is measured by means of BCVA by ETDRS visual acuity chart, spectral-domain optical coherence tomography (sdOCT), color fundus photography (CFP), fundus fluorescein angiography (FA), fundus autofluorescence (FAF), contrast sensititivy, and microperimetry. Pharmacokinetic (PK) and immunogenicity is evaluated by means of measuring plasma concentrations of hi- con 1 and anti-drug antibodies.
