Description

[Technical field]

[0001] Related Applications This application claims priority to U.S. Provisional Patent Application No. 62 / 408,391, filed October 14, 2016; European Patent Application No. EP16306166.6, filed September 14, 2016; and U.S. Provisional Patent Application No. 62 / 250,269, filed November 3, 2015, each of which is incorporated by reference in its entirety.

[0002] The present invention relates to the field of therapeutic treatment of uveitis and macular edema. More specifically, the present invention relates to the use of interleukin-6 receptor (IL-6R) antagonists, such as anti-IL-6R antibodies, to treat uveitis. [Background technology]

[0003] Interleukin-6 is a major cytokine with a wide range of biological activities, including regulation of immune reactivity, acute phase response, inflammation, carcinogenesis and hematopoiesis (Non-Patent Document 1). Overproduction of IL-6 has been found to play a pathological role in chronic inflammatory diseases, including rheumatoid arthritis (RA). IL-6 has also been consistently shown to be elevated in the vitreous of patients with non-infectious uveitis (Non-Patent Document 2; Non-Patent Document 3; Non-Patent Document 4; and Non-Patent Document 5).

[0004] IL-6 interacts directly with the IL-6Rα subunit, and the IL-6 / IL-6Rα pair forms a high-affinity complex with the glycoprotein 130 (gp130) subunit. IL-6Rα also exists in a soluble form, which participates in trans-signaling, allowing IL-6 to affect cells that do not express IL-6Rα, including synovial cells in joints (Non-Patent Document 6).

[0005] Sarilumab (SAR153191), also known as REGN88, is co-developed by Sanofi and Regeneron. Sarilumab is a fully human sequence recombinant IgG1 kappa monoclonal antibody that targets the alpha subunit of the IL-6 receptor complex (IL-6Rα). Sarilumab is a potent and specific inhibitor of IL-6 signaling. By binding to IL-6Rα with high affinity, sarilumab blocks the binding of IL-6 and disrupts the cytokine-mediated signaling cascade. Sarilumab is being evaluated in phase 3 clinical trials for the treatment of RA. Additionally, proof-of-concept studies are currently ongoing for the treatment of patients with non-infectious, intermediate, posterior or pan-uveitis.

[0006] Interleukin-6 is a key element in the pathogenesis of rheumatic conditions and inhibition of its signaling is a critical part of sarilumab's mechanism of action.

[0007] Proinflammatory cytokines associated with RA include tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1) and IL-6. Interleukin-6 is expressed in a large proportion of cells in the synovium of rheumatoid joints, and elevated levels of IL-6 are found in the serum and synovial fluid of RA patients. Elevated levels of soluble IL-6Rα have also been observed in various inflammatory diseases, including RA (Non-Patent Document 7). Interaction of IL-6 with soluble IL-6Rα leads to the formation of a soluble complex that can transactivate gp130 present on the surface of some cells, potentially being a major pathogenic mechanism of RA (Non-Patent Document 6). IL-6 mediates the pathway of TNF-α and IL-1 in the inflammatory cytokine cascade. It is downstream and therefore can represent the final common signaling pathway in a wide range of inflammatory processes.Rheumatoid arthritis is a chronic inflammatory disease characterized by persistent synovitis and progressive destruction of cartilage and bone in multiple joints.Related systemic inflammatory symptoms include fever, fatigue, anemia, increased acute phase reactants such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), and the development of autoantibodies such as rheumatoid factor (RF) (Non-Patent Document 1).

[0008] Uveitis is a term used to describe a group of intraocular inflammatory diseases that can occur at any age, but primarily affect patients of productive age (Non-Patent Document 8). Non-infectious uveitis (NIU) can arise from underlying inflammatory diseases, autoimmune disorders, tumors, or as a result of trauma to the eye. In most cases, the cause remains unknown (i.e., idiopathic uveitis) (Non-Patent Document 9).

[0009] The goal of NIU treatment is to control inflammation, prevent vision loss, and minimize the long-term complications of the disease and its treatment. Systemic corticosteroids are widely used to manage posterior segment inflammation that requires treatment, especially when it is associated with systemic disease or when bilateral ocular disease is present. Since IL-6 has been consistently shown to be elevated in the vitreous of NIU patients (Non-Patent Document 2, Non-Patent Document 3, Non-Patent Document 4, Non-Patent Document 5), blocking IL-6 signaling through IL-6Ra with sarilumab may have potential as a treatment for this disease.

[0010] We investigated the efficacy of a murine surrogate antibody (REGN844) against IL-6Rα in a murine organ-specific T-lymphocyte-mediated model of experimental autoimmune uveoretinitis (EAU) to support the treatment of non-infectious uveitis after subcutaneous injection of sarilumab in patients. In the study, REGN844 given intraperitoneally (IP) to mice at dose levels of 10 to 100 mg / kg every 3 days from day 5 after EAU induction resulted in a dose-related inhibition of non-infectious uveitis, as evidenced by a reduction in retinal thickness, morphological abnormalities, and inflammatory cell infiltration, and confirmed by histological and optical coherence tomography (OCT) measurements. Systemic (intraperitoneal) administration of a murine anti-murine IL6R antibody (REGN844) consistently ameliorates the development of vitreoretinal inflammation in a murine model of experimental autoimmune uveitis (EAU) (Non-Patent Document 10).

[0011] Macular edema involves the abnormal leakage and accumulation of fluid in the macula from damaged blood vessels in the nearby retina. A common cause of macular edema is diabetic retinopathy. See Non-Patent Document 11. Macular edema may also occur following eye surgery, in association with age-related macular degeneration, or as a result of inflammatory diseases affecting the eye. In fact, any disease that damages the blood vessels of the retina can cause macular edema.

[0012] Sarilumab (SAR153191), also known as REGN88, has been evaluated for the treatment of rheumatoid arthritis (RA) and for the treatment of non-infectious intermediate, posterior and total uveitis. Sarilumab is a recombinant human monoclonal antibody of the immunoglobulin G1 (IgG1) kappa isotype that targets the interleukin-6 receptor a subunit (IL-6Rα). Sarilumab has been demonstrated to bind to human IL-6Rα, block interleukin-6 (IL-6) signaling, and not induce signaling in the absence of IL-6. In ex vivo assays, sarilumab did not demonstrate antibody-dependent cellular cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC) in relevant cell types, where sarilumab binding was verified by fluorescence activated cell sorter (FACS) analysis.

Any multispecific antibody format, including the exemplary bispecific antibody formats disclosed herein, can be tailored for use in the context of the antigen-binding fragments of antibodies of the present invention using routine techniques available in the art.

[0188] In a specific embodiment, the antibodies or antibody fragments for use in the methods of the invention may be multispecific antibodies, which may be specific for different epitopes of one target polypeptide or may contain antigen-binding domains specific for epitopes of more than one target polypeptide. An exemplary bispecific antibody format that can be used in the context of the present invention is a bispecific antibody format comprising a first immunoglobulin (Ig)C H3 Domains and secondary Ig C H3 The use of a first and a second Ig C domain H3 The domains differ from each other by at least one amino acid, and the at least one amino acid difference reduces binding of the bispecific antibody to Protein A compared to a bispecific antibody lacking the amino acid difference. H3 The domain binds to protein A and is a second IgC H3 The domain contains a mutation that reduces or abolishes Protein A binding, such as the H95R modification (according to IMGT exon numbering; H435R in EU numbering). H3 The second C may further comprise a Y96F modification (according to IMGT; Y436F in EU). H3 Further modifications that may be found in include: for IgG1 antibodies, D16E, L18M, N44S, K52N, V57M and V 82I (according to IMGT; D356E, L358M, N384S, K392N, V397M and V422I according to EU); for IgG2 antibodies, N44S, K52N and V82I (according to IMGT; N384S, K392N and V422I according to EU); for IgG4 antibodies, Q15R, N44S, K52N, V57M, R69K, E79Q and V82I (according to IMGT; Q355R, N384S, K392N, V397M, R409K, E419Q and V422I according to EU). Mutations on the above bispecific antibody formats are considered to be within the scope of the present invention.

[0189] In another specific embodiment, the antibody is sarilumab (SAR153191). The heavy chain variable region of sarilumab comprises the sequence of SEQ ID NO:2.

[0190] The light chain variable region of sarilumab comprises the sequence of SEQ ID NO:3.

[0191] As used herein, a "neutralizing" or "blocking" antibody refers to an antibody whose binding to hIL-6R results in the inhibition of the biological activity of hIL-6. This inhibition of the biological activity of hIL-6 can be investigated by measuring one or more indicators of the biological activity of hIL-6, such as hIL-6-induced cell activation and binding of hIL-6 to hIL-6R, which are known in the art (see Examples below).

[0192] The fully human anti-IL-6R antibodies disclosed herein may contain one or more amino acid substitutions, insertions and / or deletions in the framework and / or CDR regions of the heavy and light chain variable domains compared to the corresponding germline sequences. Such mutations can be easily ascertained by comparing the amino acid sequences disclosed herein to germline sequences available, for example, from public antibody sequence databases. The present invention includes antibodies and antigen-binding fragments thereof derived from any of the amino acid sequences disclosed herein, in which one or more amino acids in one or more framework and / or CDR regions are backmutated to the corresponding germline residue(s) or to conservative amino acid substitutions (natural or non-natural) of the corresponding germline residue(s) (such sequence changes are referred to herein as "germline backmutations"). Starting from the heavy and light chain variable region sequences disclosed herein, one skilled in the art can easily generate numerous antibodies and antigen-binding fragments containing one or more individual germline backmutations or combinations thereof. In certain embodiments, all of the framework and / or CDR residues in the VH and / or VL domains are backmutated to the germline sequence. In other embodiments, only certain residues are backmutated to the germline sequence, for example, the mutated residue is only found in the first 8 amino acids of FR1 or the last 8 amino acids of FR4, or the mutated residue is only found in CDR1, CDR2 or CDR3. Furthermore, the antibodies of the present invention can contain any combination of two or more germline backmutations in the framework and / or CDR regions, i.e., where certain individual residues are backmutated to the germline sequence and certain other residues that differ from the germline sequence are maintained.Once obtained, antibodies and antigen-binding fragments containing one or more germline reversion mutations can be readily tested for one or more desired properties, such as improved binding specificity, increased binding affinity, improved or enhanced antagonist or agonist biological properties (as the case may be), reduced immunogenicity, etc. Antibodies and antigen-binding fragments obtained in this general manner are encompassed within the present invention.

[0193] The term "epitope" refers to an antigenic determinant that interacts with a specific antigen-binding site in the variable region of an antibody molecule, known as a paratope. A single antigen may have more than one epitope. Epitopes can be conformational or linear. Conformational epitopes are generated by spatially juxtaposed amino acids from different segments of a linear polypeptide chain. Linear epitopes are those generated by adjacent amino acid residues of a polypeptide chain. In certain circumstances, epitopes can include saccharide moieties, phosphoryl groups, or sulfonyl groups on the antigen.

[0194] The anti-hIL-6R antibody may be sarilumab (SAR153191). In one embodiment, sarilumab is defined as an antibody comprising a heavy chain variable region of SEQ ID NO:2 and a light chain variable region of SEQ ID NO:3.

[0195] The amino acid sequence of SEQ ID NO:2 is EVQLVESGGGLVQPGRSLRLSCAASRFTFDDYAMHWVRQAPGKGLEWVSGISWNSGRIGYADSVKGRFTISRDNAENSLFLQMNGLRAEDTALYYCAKGRDSFDIWGQGTMVTVSS.

The anti-hIL6R antibody may be tocilizumab. Tocilizumab is also known as "humanized PM-1 antibody" or "hMP1" and was obtained by grafting the complementarity determining regions (CDRs) of the mouse antibody PM-1 (Hirata et al., J. Immunology (1989) vol. 143, pp. 2900-2906) onto a human antibody (International Patent Application Publication No. WO 92 / 19759). International Patent Application Publication No. WO 96 / 11020 shows that the humanized PM1 antibody is effective in an animal model of rheumatoid arthritis. Tocilizumab is marketed under the trade name Actemra®.

[0200] Dosage Range As used herein, "administered at about X to about Y mg" means that the referenced substance is administered at any value within the specified range, including the endpoints of that range. For example, "the dose of anti-hIL-6R antibody administered to a patient is between 10 mg and 500 mg" includes administration of 10 mg of anti-hIL-6R antibody, 500 mg of anti-hIL-6R antibody, and all doses in between.

[0204] Uveitis As used herein, uveitis refers to any intraocular inflammatory disease or disorder. See Taber's Cyclopedic Medical Dictionary, 1997 (18th Edition), edited by Clayton L. Thomas, MD, M.PH., published by FADAvis Company, Philadelphia, PA. Different types of uveitis are described below. Uveitis can involve both uveal tract structures (e.g., iris, ciliary body, and choroid) and non-uveal portions of the eye (e.g., retina and cornea). Uveitis can include iritis (i.e., inflammation of the iris), cyclitis (i.e., inflammation of the ciliary body), panuveitis (i.e., inflammation of the entire uveal vascular layer of the eye), posterior uveitis, and anterior uveitis. Intermediate uveitis, also called peripheral uveitis, is an inflammation that occurs immediately after the iris and lens in the area of ​​the ciliary body and pars plana. and is also referred to as "cyclitis" and "pars planitis." See also U.S. Patent No. 9,139,646; U.S. Patent No. 8,895,521; and U.S. Patent Application Publication No. 20090082288A1, each of which is fully incorporated herein. Uveitis can be acute (i.e., signs and symptoms occur suddenly and last a short time, e.g., days or weeks), or chronic (i.e., onset is gradual and lasts longer than acute uveitis, e.g., weeks, months or years).

[0205] "Posterior uveitis" is also often referred to as chorioretinitis, which is a type of uveitis involving inflammation of the choroid and retina. See also Suttorp-Schulten et al., 1996, Ocul Immunol Inflamm. 4(4):207-217. As used herein, "anterior uveitis" refers to iridocyclitis, which is a disorder characterized by inflammation of the iris and ciliary body and / or iritis. Anterior uveitis commonly results in symptoms such as pain, redness, photophobia, and decreased vision. Signs of anterior uveitis include pupillary constriction and hyperemia of the conjunctiva adjacent to the cornea, known as perilimbal flushing. See also Gordon et al., 1998, J Clin Immunol. 18(4):264-271. "Diffuse" uveitis refers to a type of uveitis characterized by inflammation involving all parts of the eye, including the anterior, intermediate, and posterior structures. See Huang et al., Ocular Inflammatory Disease and Uveitis Manual: Diagnosis and Treatment.

[0206] In various embodiments, inflammatory products of ocular inflammation (e.g., cells, fibrin, excess proteins) can be found in the liquid spaces of the eye, for example, in the anterior chamber, posterior chamber, and vitreous space.

[0207] Uveitis can occur following surgical or traumatic injury to the eye; as a component of an autoimmune disorder (e.g., rheumatoid arthritis, Behcet's disease, sarcoidosis, etc.); as an isolated immune-mediated eye disorder (such as pars planitis or iridocyclitis); as a disease not associated with a known etiology; and following certain systemic diseases that deposit antibody-antigen complexes in the uveal tissue. Uveitis includes ocular inflammation associated with Behcet's disease, sarcoidosis, Vogt-Koyanagi-Harada syndrome, etc. In various embodiments, non-infectious uveitis occurs in the absence of an infectious agent.

[0208] Macular edema As used herein, "macular edema" refers to the accumulation of fluid in the macular region of the retina. The fluid affects the blood supply to the macula and / or retina, negatively impacting vision. Symptoms of macular edema include worsening vision, micropsia, metamorphopsia, reduced color vision, and central or central scotoma. See U.S. Patent No. 6,046,223. There are different types of macular edema, including cystoid macular edema, which is a disorder that affects the central retina or macula. Cystoid macular edema is often diagnosed by the presence of multiple cystoid (bubble-like) areas of fluid appearing in the macula, causing retinal swelling or edema. In various embodiments, the subject suffers from diabetic retinopathy, which can cause macular edema.

[0209] Therapeutic Administration and Formulations The methods described herein include administering to a subject a therapeutically effective amount of an anti-hIL-6R antibody. As used herein, the phrase "therapeutically effective amount" refers to a dose of a therapeutic agent that results in treatment of uveitis and / or macular edema. As used herein, "treating" refers to causing a detectable improvement in one or more symptoms associated with uveitis and / or macular edema, or to the induction of a biological effect (e.g., a specific biogenic effect) that correlates with the underlying pathomechanism(s) that results in the condition or symptom(s). The term macular edema refers to causing uveitis and macular edema (decreased levels of ocular markers). For example, the following symptoms or conditions are associated with uveitis and macular edema: elevated vitreous haze (VH) levels, decreased best corrected visual acuity (BCVA), increased amount of fluid in the macula, signs of ocular inflammation, retinal vascular leakage, increased central retinal thickness (CRT) and ocular inflammation in the anterior chamber. More specifically, symptoms associated with macular edema include blurred or wavy vision near the center of the visual field, ocular inflammation, impaired vision, impaired color perception, tissue thickening and ocular vascular leakage. In certain embodiments, the symptoms of macular edema are improved by reducing excess fluid in the macula.

[0210] Vitreous Haze Value (VH) Vitreous haze is assessed by the Miami 9-point scale (Grades 0 to 8) (see Davis JL et al., Am J Ophthalmol. 2010;150(5):637-41). Vitreous haze is the obscuration of fundus details by vitreous cells and protein exudation. It affects vision more significantly than anterior chamber inflammation and is therefore commonly used as an outcome measure for clinical trials involving intermediate, posterior or total uveitis.

[0211] BCVA (ETDRS letter score) Visual acuity (VA) can be assessed using the BCVA score, which is assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) standardized protocol. Best corrected visual acuity can be measured at each visit.

[0212] Central retinal thickness (CRT) Central retinal thickness (CRT) can be measured by Spectral Domain Optical Coherence Tomography (SD-OCT), which can be performed using standard techniques.

[0213] Clinical evaluation score Patients can be identified as "active" based on one of the following criteria (index variables) at baseline and can be evaluated for that parameter after treatment to determine if the patient has reached an "inactive" state after treatment: VH, CRT and BCVA. Secondary variables: Clinical Assessment Score (CAS) [regardless of the parameter of activity] Improved: I, Unchanged: N, Worsened: W.

[0214] Improved: A score of I (improved) is assigned to what is considered to be a clinically meaningful improvement. A score of N (no change) is assigned when there is no change or when the change is considered clinically insignificant. A score of W (worsening) is assigned when the change places the study participant at short-term risk of blindness and requires discontinuation from the study.

[0215] [Table 1]

[0216] When several variables are available for a type of uveitis, the variable with the worst baseline condition (clinical judgment) can be selected as the index.

[0217] [Table 2]

[0218] All signs of inflammation other than the indicator variable for a given patient can be considered as secondary variables for that patient. Primary signs of inflammation that are not selected as indicator variables can be considered as secondary variables. Grading is primarily used in stopping rules; an improvement in a secondary variable is not considered an improvement even if that secondary variable is a primary sign of inflammation (but is not selected as an indicator variable for that patient).

[0219] In certain embodiments, the VH level is reduced by 2 points on the Miami 9 point scale. According to other embodiments, the VH level is reduced by 1, 2, 3, 4, 5, 6, 7, 8 or 9 points on the Miami 9 point scale. According to other embodiments, the VH level is reduced by 1-2, 1-3, 1-4, 2-4 or 3-5 points on the Miami 9 point scale.

[0220] In certain embodiments, the BCVA is improved by 10 letters on the EDTRS chart. According to other embodiments, the BCVA is improved by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 letters on the EDTRS chart. According to other embodiments, the BCVA is improved by 5-15, 7-13, or 8-12 letters on the EDTRS chart.

[0221] In other embodiments, the therapeutically effective amount reduces the dose of corticosteroid administered to the subject. In certain embodiments, the dose of corticosteroid is reduced to less than 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 5 or 1 mg / day. In certain embodiments, the corticosteroid is prednisone.

[0222] The therapeutically effective amount of anti-hIL-6R antibody administered to a patient according to the method of the present invention will vary depending on the age and size (e.g., body weight or body surface area) of the patient, as well as the route of administration and other factors well known to those skilled in the art.

See also Powell et al., "Compendium of excipients for parenteral formulations," PDA (1998) J Pharm Sci Technol 52:238-311.

[0230] The dosage may vary depending on the age and weight of the subject to be administered, the target disease, condition, route of administration, etc. A variety of delivery systems are known and can be used to administer the pharmaceutical composition of the present invention, such as, for example, encapsulation in liposomes, microparticles, microcapsules, and receptor-mediated endocytosis (see, for example, Wu et al. (1987) J. Biol. Chem. vol. 262: 4429-4432). Methods of introduction include, but are not limited to, intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, and oral routes. The composition may be administered by any convenient route, such as by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e.g., oral mucosa, rectal and intestinal mucosa, etc.), and may be administered together with other biologically active agents. Administration may be systemic or local. The hIL-6R antibody may be administered subcutaneously.

[0231] Pharmaceutical compositions can also be delivered in the form of vesicles, particularly liposomes (see Langer (1990) Science 249:1527-1533). In certain circumstances, the pharmaceutical composition can be delivered in a controlled release system, for example, using a pump or polymeric material. In another embodiment, the controlled release system can be placed in close proximity to the target of the composition, thus requiring only a fraction of the systemic dose.

[0232] The injectable preparations may include dosage forms for intravenous, subcutaneous, intradermal and intramuscular injections, local injections, drip infusions, etc. These injectable preparations may be prepared by known methods. For example, the injectable preparations may be prepared by dissolving, suspending or emulsifying the above-mentioned antibody or its salt in a sterile aqueous or oily medium conventionally used for injections. Aqueous media for injection include, for example, physiological saline, isotonic solutions containing glucose and other auxiliary agents, etc., which may be prepared by dissolving in water, etc., in the presence of suitable solubilizing agents such as alcohols (e.g., ethanol), polyhydric alcohols (e.g., propylene glycol, polyethylene glycol), nonionic surfactants [e.g., polysorbate 80, HCO-50 (polyoxyethylene (50 mol) adduct of hydrogenated castor oil)], etc. As the oil medium, for example, sesame oil, soybean oil, etc. are used, which can be used in combination with a solubilizer such as benzyl benzoate, benzyl alcohol, etc. The injection thus prepared can be filled into a suitable ampoule.

[0233] Conveniently, the above-mentioned oral or parenteral pharmaceutical composition is prepared in a dosage form of a unit dose suitable for the dosage of the active ingredient. Such dosage forms of unit dose include, for example, tablets, pills, capsules, injections (ampoules), suppositories, etc. The amount of hIL-6R antibody contained is generally about 100 to about 200 mg per subcutaneous dosage form.

[0234] According to the methods disclosed herein, the anti-hIL-6R antibody (or pharmaceutical formulation comprising the antibody) can be administered to the patient using any acceptable device or mechanism. For example, administration can be accomplished using a syringe and needle, or with a reusable pen and / or autoinjector delivery device. The methods of the present invention include the use of a number of reusable pens and / or autoinjector delivery devices to administer the anti-hIL-6R antibody (or pharmaceutical formulation comprising the antibody). Examples of such devices include, but are not limited to, the AUTOPEN™ (Owen Mumford, Inc., Woodstock, UK), the DISETRONIC™ pen (Disetronic Medical Systems, Bergdorf, Switzerland), the HUMALOG MIX75 / 25™ pen, the HUMALOG™ pen, the HUMALIN70 / 30™ pen (Eli Lilly and Co., Indianapolis, IN), the NOVOPEN™ I, II and III (Novo Nordisk, Copenhagen, Denmark), the NOVOPEN JUNIOR™ (Novo Nordisk, Copenhagen, Denmark), the BD™ pen (Becton Dickinson, Franklin Lakes, NJ), the OPTIPEN™, the OPTIPEN PRO™, the OPTIPEN™, the AUTOPEN™, the DISETRONIC™ pen (Disetronic Medical Systems, Bergdorf, Switzerland), the HUMALOG MIX75 / 25™ pen, the HUMALOG™ pen, the HUMALIN70 / 30™ pen (Eli Lilly and Co., Indianapolis, IN), the NOVOPEN™ I, II and III (Novo Nordisk, Copenhagen, Denmark), the NOVOPEN™ JUNIOR™ (Novo Nordisk, Copenhagen, Denmark), the BD™ pen (Becton Dickinson, Franklin Lakes, NJ), the OPTIPEN™, ... Disposable pens and / or autoinjector delivery devices applicable for subcutaneous delivery of the pharmaceutical compositions of the present invention include, but are not limited to, the SOLOSTAR pen (Sanofi-Aventis), FLEXPEN (Novo Nordisk) and KWIKPEN (Eli Lilly), SURECLICK autoinjector (Amgen, Thousand Oaks, CA), PENLET (Haselmeier, Stuttgart, Germany), EPIPEN (Dey, LP), and HUMIRA pen (AbbVie Inc., North Chicago, IL), to name a few.

[0235] The use of a microinjector to deliver an anti-hIL-6R antibody (or a pharmaceutical formulation comprising the antibody) to a patient is also contemplated herein. As used herein, the term "microinjector" refers to a subcutaneous delivery device designed to gradually administer a large volume (e.g., up to about 2.5 mL or more) of a therapeutic formulation over an extended period of time (e.g., about 10, 15, 20, 25, 30 minutes or more). See, for example, U.S. Pat. No. 6,629,949; U.S. Pat. No. 6,659,982; and Meehan et al., J. Controlled Release 46:107-116 (1996). Microinjectors are particularly useful for the delivery of large doses of therapeutic proteins and / or viscous solutions contained within a range of high concentrations (e.g., about 100, 125, 150, 175, 200 mg / mL or more).

[0236] Patient population In certain embodiments, the methods and compositions described herein are directed to specific patient populations. These populations include subjects with a vitreous haze (VH) level of 2 or greater on the Miami 9-point scale. In other embodiments, subjects in this population have a VH level of greater than 3, 4, 5, 6, 7, or 8. According to other embodiments, subjects in this population have a VH level of greater than 4 on the Miami 9-point scale.

[0237] In other embodiments, the subjects in this population have macular edema. In certain embodiments, the subjects with macular edema have a CRT greater than 300 μm.

[0238] In other embodiments, subjects in this population have other signs of intraocular inflammation, such as perivascular sheath formation of retinal vessels and leakage of retinal vessels.

[0239] According to certain embodiments, the methods of the invention comprise selecting a patient exhibiting any of the above characteristics and administering to the patient an anti-IL-6R antibody as described elsewhere herein.

[0240] Combination therapy The present invention includes a method of treating uveitis and / or macular edema, comprising administering an anti-hIL-6R antibody to a patient in need of such treatment. In certain embodiments, the anti-hIL-6R antibody is administered as a "monotherapy" or single therapeutic agent. In alternative embodiments, the anti-hIL-6 antibody is administered in combination with at least one additional therapeutic agent. Examples of additional therapeutic agents that can be administered in combination with the anti-hIL-6R antibody in the practice of the methods of the present invention include, but are not limited to, corticosteroids and any other compounds known to treat, prevent or ameliorate uveitis and / or macular edema in human subjects. Specific non-limiting examples of additional therapeutic agents that can be administered in combination with the anti-hIL-6R antibody in the context of the methods of the present invention include, but are not limited to, methotrexate and prednisone. In the methods, the additional therapeutic agent(s) can be administered simultaneously with the anti-hIL-6R antibody or sequentially. For example, a pharmaceutical formulation containing both the anti-hIL-6R antibody and at least one additional therapeutic agent can be made for simultaneous administration. The amount of an additional therapeutic agent to be administered in combination with an anti-hIL-6R antibody in practicing the methods of the present invention can be readily determined using routine methods that are known and readily available in the art.

[0246] The present disclosure of the present invention provides a method of ameliorating symptoms associated with uveitis, comprising any of the following:

[0247] A method comprising administering to a subject in need thereof 100 to 200 mg of sarilumab (SAR153191) every two weeks and 15 to 80 mg of prednisone per day.

[0248] A method comprising administering to a subject in need thereof about 200 mg of sarilumab (SAR153191) every two weeks and 15 to 80 mg of prednisone per day. EXAMPLES

[0249] Example 1 Anti-IL6R antibodies are effective in treating uveitis and / or macular edema in humans. A study was performed to evaluate the efficacy and safety of sarilumab administered subcutaneously every 2 weeks (q2w) in patients with non-infectious, intermediate, posterior or total uveitis.

[0250] This was a randomized, double-masked, placebo-controlled, parallel-group study. Randomization was 2:1 (sarilumab:placebo) and patients were stratified by vitreous haze (VH) level (VH=4 vs. VH<4), macular edema (Yes, No) and uveitis etiology (systemic and idiopathic).

[0251] The primary objectives were to evaluate: efficacy of sarilumab 200 mg q2w at week 16 in patients with noninfectious uveitis (NIU); change in best corrected visual acuity (BCVA); safety of subcutaneous sarilumab in patients with NIU; change in macular edema; change in other signs of ocular inflammation; effect on retinal vascular leakage; effect of sarilumab on reducing concomitant immunosuppressive therapy at week 16; change in ocular inflammation in the anterior chamber; pharmacokinetics (PK) of sarilumab in patients with NIU; and immunogenic anti-drug antibodies (ADAs). Effect on serum biomarkers of inflammation such as high-sensitivity C-reactive protein (hs-CRP) and serum amyloid A (SAA); effect on underlying systemic disease in time; effect of sarilumab on ocular disease at week 52; effect of sarilumab on reducing concomitant immunosuppressive therapy at week 52; and characteristics of uveitis at the time of symptom exacerbation were also evaluated.

[0252] The study included two periods: Main treatment period (Part A): At enrollment, patients had to have already been receiving treatment with prednisone or equivalent steroids (either as monotherapy or in combination with methotrexate); sarilumab or placebo was added to continued therapy. After two study treatment injections (4th visit), if improvement was confirmed in at least two consecutive evaluations, tapering of background therapy was initiated according to the prescribed rules. Clinical (efficacy and safety) evaluations were performed every other week for 16 weeks. Extension Treatment Period (Part B): If a patient completed Part A and was confirmed as a responder, he / she continued the same double-masked treatment until the completion of 1 year (last injection at week 50). Clinical (efficacy and safety) evaluations were performed every 4 weeks.

[0253] In addition, there were two further options: Open-label treatment period (Part C): Patients who progressed at week 16 or were confirmed non-responders at any time in Part A were eligible to continue treatment with open-label sarilumab in Part C, at the investigator's discretion and in participating countries where this procedure was permitted. Patients were treated for up to an additional 34 weeks (up to 18 additional injections). Efficacy and safety assessments were performed. Patients were offered an optional genomics substudy to accumulate DNA and RNA for research purposes. Randomization of approximately 57 patients (assuming 80% statistical power for the comparison of an expected 59% response with sarilumab and an expected 20% response with placebo) was planned.

[0254] Patients with non-infectious intermediate, posterior or pan-uveitis with active disease or recently active (active in the past 3 months) disease. Patients were to receive corticosteroids as the sole immunosuppressive therapy or in combination with methotrexate. No other immunosuppressive therapy was permitted. Patients had to be receiving oral prednisone (≥15 mg and <80 mg / day [or equivalent oral corticosteroid]) orally or equivalent intravenously, intramuscularly or subcutaneously, either as the sole immunosuppressive therapy or in combination with methotrexate (MTX) (≤25 mg / week).

[0255] The primary endpoints were (1) at least a 2-step reduction in VH (Miami 9-point scale) determined in the study eye at week 16 or (2) the proportion of patients with a prednisone or equivalent oral corticosteroid dose of <10 mg / day at week 16. Other efficacy endpoints at week 16 included baseline change in central retinal thickness (CRT), best corrected visual acuity, corticosteroid dosage, retinal vascular leakage (FA) (pilot), and clinical assessment scores (pilot).

[0256] Subjects A total of 58 patients were randomized: 38 patients in the sarilumab group and 20 patients in the placebo group. All 58 patients were exposed to the IMP (investigational medicinal product) and were included in the mITT (modified intent to treat) population. For clarity, the mITT population includes all randomized patients who received at least one IMP injection. A total of 28 (73.7%) patients in the sarilumab group and 13 (65.0%) patients in the placebo group completed the primary treatment period (Part A); one patient in the placebo group was not included in the completion population due to a non-evaluable primary efficacy endpoint (VH assessment) at week 16.

[0257] Baseline demographics and patient characteristics were balanced between treatment groups (Table 1). Of note, the number of patients with macular edema (defined as CRT = 300 μm) was lower in the sarilumab group compared with the placebo group (21 [55.3%] vs. 13 [65.0%], respectively).

[0258] [Table 3]

[0259] The median baseline corticosteroid dose was 20 mg / day. Of the 58 patients, 1 (1.7%) had a corticosteroid dose less than 15 mg / day at baseline, 45 (77.6%) had a corticosteroid dose of 15 or 20 mg / day at baseline, 12 (20.7%) had a corticosteroid dose of 20 or 40 mg / day at baseline, and 0 patients had a corticosteroid dose of more than 40 mg / day at baseline. Furthermore, the majority of patients, 55 (94.8%), had active disease at baseline, and in 29 (50%) patients this was total uveitis.

[0260] The median time from initial diagnosis was 17.92 months (1.49 years), which was higher in the placebo group (24.02 months) when compared with the sarilumab group (17.58 months).

[0261] At baseline, the number of patients with adjudicated VH<4 was higher in the sarilumab group (49 patients [86.0%]) compared with the placebo group (17 patients [85.0%]). The median adjudicated CRT at baseline was 1.0 vs. 1.0 in the placebo group (308.0 μm). In comparison, the percentage of patients with macular edema (defined as CRT ≥ 300 μm) was lower in the sarilumab group compared to the placebo group (i.e., 18 patients [48.6%] in the sarilumab group vs. 14 patients [70.0%] in the placebo group, respectively). See Table 2.

[0262] [Table 4]

[0263] [Table 5]

[0264] Investigator ocular assessments of VH<4 and VH<3 at baseline are listed in Table 3 below. A total of 14 (24.1%) patients had VH=4; 9 patients ([23.7%]) were identified in the sarilumab group and 5 patients ([25.0%]) were identified in the placebo group). The number of patients with BCVA=70 letters at baseline was lower in the sarilumab group compared to the placebo group (i.e., 23 patients [60.5%] in the sarilumab group vs. 16 patients [80.0%] in the placebo group, respectively). The majority of patients (55 patients; 94.8%) presented with abnormal fluorescein angiograms (FA) at baseline. See Table 3.

[0265] [Table 6]

[0266] [Table 7]

[0267] [Table 8]

[0268] [Table 9]

[0269] [Table 10]

[0270] Of note, discrepancies were observed between investigator and adjudicated assessments of VH. In more than 52.6% of the patient population, the adjudicated assessment of VH was milder than the investigator assessment. Furthermore, there was a proportion of patients with a difference of 2 or more levels between both assessments. Therefore, a further sensitivity analysis for the primary endpoint using investigator VH values ​​was included. No difference was observed between investigator and adjudicated assessments of CRT in 55.2% of patients, and in 12 (20.7%) patients, the adjudicated assessment of CRT was milder than the investigator assessment.

[0271] Dosage and duration Exposure to injections was comparable in both groups, with a mean of 14.1 weeks of IMP injection exposure during the 16 weeks of Part A. Overall compliance was also comparable in both groups; all 58 patients received at least 80% of the theoretical dose.

[0272] efficacy Primary Efficacy Endpoint The primary endpoint (proportion of patients with a 2-step reduction in VH or corticosteroid dose <10 mg / day at week 16) analysis was based on adjudicated VH values. The results of the primary endpoint analysis are shown in Table 4.

[0273] The proportion of patients with a 2-step reduction in VH or a corticosteroid dose <10 mg / day was higher in the sarilumab group (46.1%) when compared with placebo (30.0%), but the difference was not statistically significant (p=0.2354).

[0274] A primary efficacy endpoint was chosen to investigate the efficacy of sarilumab in reducing ocular inflammation associated with uveitis, which was expected to include patients with significant VH scores, in whom a reduction in VH values ​​was essential. Finally, the recruited population showed lower VH values, since patients with severe VH were treated with concomitant immunosuppressive medications that were not tolerated in this study.

[0275] Further endpoints (e.g., BCVA) aimed to assess the effect of sarilumab on functional parameters.

[0276] Comparisons of the proportion of responders between the two treatment groups were performed for each of the complete data sets using the Cochran-Mantel-Haenszel (CMH) test at a two-sided alpha level of 0.10.

[0277] [Table 11]

[0278] [Table 12]

[0279] The results of the sensitivity analysis of a 2-step reduction in VH or a corticosteroid dose <10 mg / day, which considered missing responder status as non-responder, were similar to the primary analysis (see Table 6).

[0280] Components for the proportion of patients with ≥2-stage reduction in VH or a dose of prednisone or equivalent oral corticosteroid <10 mg / day at week 16, in which missing responders were considered non-responders, were also calculated.

[0281] [Table 13]

[0282] Other Primary Efficacy Endpoints The proportion of patients with a 2-step reduction in VH or a corticosteroid dose <10 mg / day was nominally significantly higher in the sarilumab group (64.0%) compared to placebo (35.0%) (p=0.0372). See Table 7. Components for the proportion of patients with ≥2-step reduction in VH or a prednisone or equivalent oral corticosteroid dose <10 mg / day at Week 16 based on investigator readings were also calculated. See Table 8.

[0283] [Table 14]

[0284] [Table 15]

[0285] Key Secondary Efficacy Endpoints Change from baseline in assessed VH Statistically significant differences in adjudicated VH change from baseline were observed between the sarilumab and placebo treatment groups. The LS mean change in adjudicated VH from baseline to week 16 was , was higher in the sarilumab group (-0.87) compared with the placebo group (-0.13), with a LS mean difference vs. placebo of -0.74 (90% CI: -1.223 to -0.262); p = 0.0127. See Table 9.

[0286] [Table 16]

[0287] Vitreous Haze Value Preliminary Conclusion At baseline, only seven patients in this population presented with VH >=4. In general, severely ill patients were more difficult to recruit to this study, as the standard of care for severely ill patients includes several concurrent immunosuppressive therapies that were prohibited in this study. Furthermore, discrepancies in VH assessments from pretreatment evaluations between the investigator and the rater were noted. At week 16, investigator assessment The proportion of patients with a 2-step reduction in VH by adjudication or a corticosteroid dose <10 mg / day was statistically significantly higher in the sarilumab group (64.0%) compared to placebo (35.0%) (OR: 3.7 (90% CI: 1.3 to 10.4, p = 0.0372). Furthermore, the change in VH by adjudicated assessment was statistically significantly greater when compared to the placebo group (LS mean difference vs. placebo of -0.74 (90% CI: -1.223 to -0.262, p = 0.0127).

[0288] Prednisone or oral corticosteroid dose At week 12, after five injections of sarilumab, notable differences in oral corticosteroid doses were observed when compared with the placebo group.

[0289] The LS mean change in prednisone or oral corticosteroid dose from baseline to week 16 was higher in the sarilumab group (-11.20 mg / day) compared with the placebo group (-7.85 mg / day), but the difference was not statistically significant.

[0290] Determined central retinal thickness The LS mean change in adjudicated CRT from baseline to week 16 decreased more in the sarilumab group (-35.4 μm) when compared to the placebo group (-8.9 μm), with a placebo LS mean difference of -26.5 (90% CI: -50.41 to -2.68) (p=0.0683). Because eight patients in the study presented with very high baseline CRT values ​​that were more likely to show improvement (Table 10), the MMRM model planned in SAP for the mITT population was not suitable to fit the change in adjudicated CRT (confirmed by the Studentized residual plot). An analysis evaluating the change from baseline in adjudicated CRT in the mITT population excluding patients with high baseline CRT was also performed and is detailed in Table 10. Excluding patients with high baseline CRT, the LS mean change in adjudicated CRT from baseline to week 16 decreased in the sarilumab group (-5.27 μm) and increased in the placebo group (1.79 μm), with a placebo LS mean difference of -7.06 (90% CI: -22.022 to 7.904) (p=0.4328). The LS mean change in adjudicated CRT from baseline to week 16 decreased in the sarilumab group (-6.4%) compared with no change in the placebo group, with a placebo LS mean difference of -6.4% (90% CI: -12.374 to -0.350) (p=0.0825) (Table 10).

[0291] [Table 17]

[0292] Best corrected visual acuity BCVA remains the most clinically relevant functional parameter in the treatment of uveitis. Other important variables (VH, CRT, FA findings) remain definitive inflammatory markers for the demonstration of efficacy of new treatments. At week 10, after four injections of sarilumab, a statistically significant improvement in BCVA was observed (Table 11).

[0293] A statistically significant difference in the change in BCVA from baseline to week 16 was observed. The LS mean change in BCVA from baseline to week 16 was significantly greater in the placebo group (3.87 LS mean difference vs. placebo was 4.65 (90% CI: 1.091 to 8.201); p = 0.0333. The mean improvement in the sarilumab group was 8.93 letters (almost two lines on the ETDRS chart) compared with 3.60 letters in the placebo group.

[0294] [Table 18]

[0295] BCVA and CRT Preliminary Conclusions At week 16, patients in the sarilumab group demonstrated a statistically significant improvement in BCVA compared to placebo (LS mean difference vs. placebo of 5.8 (90% CI: 1.99 to 9.67; p = 0.0153)). The mean reduction in adjudicated CRT (i.e., macular edema) was numerically higher in the sarilumab group when compared to the placebo group (LS mean difference vs. placebo 5.8 (90% CI: 1.99 to 9.67; p = 0.0153).

[0296] Anterior chamber cell score Inflammatory activity in the anterior chamber was validated through quantification of cells and proteins in the aqueous humor (Tyndall phenomenon or SUN classification). The percentage of patients with an anterior chamber cell score = 0 or at least a 2-grade reduction was similar in the sarilumab and placebo groups, 86.2% and 86.7%, respectively. Results of a sensitivity analysis that considered patients with missing data at week 16 as non-responders were similar to the original analysis.

[0297] Percentage of patients with a prednisone dose ≤ 5 mg / day (or equivalent corticosteroid) at Week 16 The proportion of patients with a prednisone dose ≤ 5 mg / day (or equivalent corticosteroid) at week 16 was similar in the sarilumab and placebo groups, 41.4% and 40.0%, respectively. Results of a sensitivity analysis that considered patients with missing data at week 16 as non-responders were similar to the original analysis. Mean changes from baseline prednisone or oral corticosteroid doses by time-windowed visits during the main treatment period were also analyzed.

[0298] Percentage of patients with a 2-step reduction in vitreous haze based on the Miami 7-point scale at 16 weeks The proportion of patients with a 2-step reduction in VH based on the Miami 7-point scale was higher in the sarilumab group (21.4%) compared with placebo (7.7%), but the difference was not statistically significant (p=0.3164). Results of a sensitivity analysis that considered patients with missing data at week 16 as non-responders were similar to the original analysis.

[0299] Exploratory Efficacy Endpoints At the end of the extended treatment period (week 52), the percentages of responders (≥2-grade reduction in adjudicated vitreous haze or prednisone dose <10 mg / day [or equivalent oral corticosteroid]), non-responders, and patients with no adjudicated response were similar in both treatment groups (Table 12). A ≥2-grade reduction was observed in 7.9% of patients in the sarilumab group compared with zero in the placebo group.

[0300] Patients who deteriorated or were confirmed non-responders at week 16 were eligible to continue treatment with sarilumab in the open-label period, part C. Of the 21 patients who entered the open-label phase, 8 (38.1%) had a corticosteroid dose <10 mg / day at week +36 and were considered responders.

[0301] [Table 19]

[0302] Change from baseline in vitreous haze at Week 52 (+36 weeks in Part C) The difference in change from baseline in adjudicated VH observed at week 16 was maintained at week 52 in patients who entered the extension treatment period. The change in adjudicated VH (according to the Miami 9-point scale) at week 52 was -1.1 in the sarilumab group and -0.4 in the placebo group.

[0303] Patients in the open-label period showed smaller VH reductions than patients who received sarilumab in the extension period. No change from baseline in adjudicated VH (according to the Miami 9-point scale) was observed at week +36, with the largest change (-0.4) observed after week 28.

[0304] Percentage of patients with prednisone dose ≤ 5 mg / day or < 10 mg / day (or equivalent oral corticosteroid) at Week 52 (Week +36 in Part C) The majority of patients in the treatment extension period had a prednisone dose ≤ 5 mg / day, which was similar in the sarilumab and placebo groups at 85.7% and 87.5%, respectively. In the open-label period, the percentage of patients with a prednisone dose < 10 mg / day was 61.5%. , and 53.8% for those taking ≦5 mg / day.

[0305] Percentage of patients with anterior chamber score = 0 or a reduction in score of 2 or more steps at Week 52 (Week +36 in Part C) At week 52, the percentage of patients who were responders (anterior chamber score = 0 or at least a 2-level reduction in score) was smaller in the sarilumab group than in the placebo group. Of the 21 patients who received sarilumab in the open-label period, 12 (57.1%) were responders. Descriptive statistics of anterior chamber cell scores by time-windowed visits were analyzed for the main and extension periods and the open-label period.

[0306] Change from baseline in best corrected visual acuity at Week 52 (+36 weeks in Part C) The difference in change in BCVA from baseline to week 16 was maintained at week 52 in patients who entered the extension treatment period. The data show that the change in BCVA at week 52 was greater in the sarilumab group compared to the placebo group.

[0307] Patients in the open-label period demonstrated improvement in BCVA, with a change from baseline BCVA of 4.5 ETDRS letters at week +36, with the greatest change (5.9 ETDRS letters) observed at week +28.

[0308] Change from baseline in central retinal thickness (generated automatically by device and software from focused spectral domain optical coherence tomography at week 52 (week +36 in part C)) The improvement in adjudicated CRT observed in patients in the sarilumab group at week 16 was maintained through week 52. The mean change from baseline adjudicated CRT at week 52 was -71.1 μm in the sarilumab group compared with -3.4 μm. However, it should be noted that patients who continued on the study into the extension period were considered responders at the end of the main treatment period.

[0309] Improvements in adjudicated CRT were also observed in patients in the open-label period. Data show that the mean change from baseline adjudicated CRT at week +36 was -37.5 μm.

[0310] Efficacy Data Analysis At week 16, the proportion of patients with a 2-stage reduction in VH by adjudicated assessment or a corticosteroid dose <10 mg / day was higher in the sarilumab group (46.1%) compared with the placebo group (30.0%), but the difference was not statistically significant (p=0.2354).

[0311] At week 16, the proportion of patients with a 2-step reduction in VH or a corticosteroid dose <10 mg / day as assessed by investigator was higher in the sarilumab group (64.0%) compared with the placebo group (35.0%; nominal p=0.0372). Other sensitivity analyses using observed cases and considering missing responder status as non-responders produced results similar to the primary analysis.

[0312] Secondary efficacy endpoint results showed statistically significant differences in adjudicated VH, BCVA, adjudicated CRT, and change from baseline CRT at 16 weeks. The LS mean change in adjudicated VH from baseline to week 16 was higher in the sarilumab group (-0.9) compared to placebo (-0.1), with a LS mean difference vs. placebo of -0.7 (90% CI: -1.223 to -0.262); p=0.0127. The LS mean change in BCVA from baseline to week 16 was 2.2 vs. placebo (3.5) Compared with placebo, LS mean difference was significantly higher in the sarilumab group (9.3), LS mean difference vs. placebo was 5.8 (90% CI: 1.99 to 9.67); p = 0.0153. The LS mean change in adjudicated CRT from baseline to week 16 decreased more in the sarilumab group (-35.4 μm) compared with placebo (-8.9 μm), LS mean difference vs placebo was -26.5 (90% CI: -50.41 to -2.68); p=0.0683. The LS mean change in adjudicated CRT from baseline to week 16 decreased in the sarilumab group (-6.4%) compared with no change in the placebo group (0.0%), LS mean difference vs placebo was -6.4% (90% CI: -12.374 to -0.350); p=0.0825.

[0313] When patients with high baseline CRT were excluded, adjudicated CRT decreased in the sarilumab group and increased in the placebo group at week 16. These data yielded an LS mean difference for sarilumab versus placebo of -7.06 (90% CI: -2.022 to 7.904; p=0.4328). Secondary endpoint analyses of anterior chamber cell score and proportion of patients with a prednisone dose ≤ 5 mg / day (or equivalent corticosteroid) at week 16 were not observed to have statistically significant differences between the sarilumab and placebo treatment groups.

[0314] Exploratory endpoint analyses showed that the differences in change from baseline in adjudicated VH, change from baseline in BCVA, and change from baseline in CRT observed at week 16 were maintained at week 52. Secondary pharmacodynamic analyses showed that both hs-CRP and SAA levels decreased from week 4 in the sarilumab group compared with the placebo group, and that suppression was maintained through week 52.

[0315] Primary and secondary analyses of patients at 52 weeks Tables 13-16 below show patient predisposition, underlying etiology, and baseline disease characteristics of the patients analyzed in this study.

[0317] [Table 21]

[0318] [Table 22]

[0319] [Table 23]

[0320] The data show that VH, BCVA and CRT were all improved in patients treated with sarilumab for 16 weeks compared to placebo-treated patients. At week 52, the sarilumab group continued to show an advantage over the placebo group, especially in terms of improving CRT in patients with demonstrable macular edema at baseline. The data described herein show that sarilumab was effective in increasing BCVA and resolving macular edema in patients with severe uveitis.
