Regeneron and Bayer Initiate Phase 3 Clinical Program for the Treatment of Wet Age-Related Macular Degeneration in China

Monday, November 28, 2011

Regeneron and Bayer Initiate Phase 3 Clinical Program for the Treatment of Wet Age-Related Macular Degeneration in China02:00 EST Monday, November 28, 2011TARRYTOWN, N.Y. and BERLIN, Nov. 28, 2011 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Bayer HealthCare today announced that they have initiated a Phase 3 clinical trial evaluating the efficacy and safety of EYLEA? (aflibercept) Injection in the neovascular form of age-related macular degeneration (wet AMD) in China. The new trial, named SIGHT, will include approximately 300 patients and will be the largest retinal trial conducted in China.  SIGHT is being led by Bayer. "Currently, only photodynamic therapy with verteporfin is approved as a treatment for wet AMD in China, and it is only approved for the subpopulation of patients with predominantly classic wet AMD," said Kemal Malik, M.D., Head of Global Development and member of the Bayer HealthCare Executive Committee.  "After reporting positive data from our large VIEW program in wet AMD, we look forward to potentially bringing this new treatment to patients with wet AMD in China."About the SIGHT Program The SIGHT (VEGF Trap-Eye: Investigation of Efficacy and Safety in Chinese patients with wet AMD) program consists of a randomized, double-masked, Phase 3 clinical trial evaluating EYLEA (known in the scientific literature as VEGF Trap-Eye) in the treatment of the neovascular form of age-related macular degeneration (wet AMD).  EYLEA will be evaluated for its effect on improving and maintaining vision when dosed as an intravitreal injection on a schedule of 2 milligrams (mg) every two months (following three initial monthly doses), as compared with Photodynamic Therapy (PDT) with verteporfin.  After assessment of the primary endpoint at week 28, all patients, including those on PDT, will receive EYLEA treatment until the end of the study at week 52.  The SIGHT study plans to randomize 300 patients.About Wet AMDAge-related Macular Degeneration (AMD) is a leading cause of acquired blindness.  Macular degeneration is diagnosed as either dry (non-exudative) or wet (exudative).  In wet AMD, new blood vessels grow beneath the retina and leak blood and fluid.  This leakage causes disruption and dysfunction of the retina creating blind spots in central vision, and it can account for blindness in wet AMD patients.  Wet AMD is the leading cause of blindness for people over the age of 65 in the U.S. and Europe.  In China, there were an estimated 540,000 newly diagnosed wet AMD patients over the age of 50 in 2010.About EYLEA? (aflibercept) Injection For Intravitreal InjectionVascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body.  Its normal role in a healthy organism is to trigger formation of new blood vessels (angiogenesis) supporting the growth of the body's tissues and organs.  However, in certain diseases, such as wet age-related macular degeneration, it is also associated with the growth of abnormal new blood vessels in the eye, which exhibit abnormal increased permeability that leads to edema. Scarring and loss of fine-resolution central vision often results.  EYLEA, known in the scientific literature as VEGF Trap-Eye, is a recombinant fusion protein, consisting of portions of human VEGF receptors 1 and 2 extracellular domains fused to the Fc portion of human IgG1 and formulated as an iso-osmotic solution for intravitreal administration.  EYLEA acts as a soluble decoy receptor that binds VEGF-A and placental growth factor (PlGF) and thereby can inhibit the binding and activation of these cognate VEGF receptors.IMPORTANT PRESCRIBING INFORMATIONIn this U.S. EYLEA is indicated for the treatment of patients with neovascular age-related macular degeneration (wet AMD).  The recommended dose for EYLEA is 2 mg administered by intravitreal injection every four weeks (monthly) for the first 12 weeks (3 months), followed by 2 mg once every eight weeks (2 months).  Although EYLEA may be dosed as frequently as 2 mg every four weeks (monthly), additional efficacy was not demonstrated when EYLEA was dosed every four weeks compared to every eight weeks.IMPORTANT SAFETY INFORMATION EYLEA is contraindicated in patients with ocular or periocular infections, active intraocular inflammation, or known hypersensitivity to aflibercept or to any of the excipients in EYLEA.Intravitreal injections, including those with EYLEA, have been associated with endophthalmitis and retinal detachments.  Proper aseptic injection technique must always be used when administering EYLEA.  Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately.Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection, including with EYLEA.  Sustained increases in intraocular pressure have also been reported after repeated intravitreal dosing with VEGF inhibitors.  Intraocular pressure and the perfusion of the optic nerve head should be monitored and managed appropriately.There is a potential risk of arterial thromboembolic events (ATEs) following use of intravitreal VEGF inhibitors, including EYLEA, defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause).  The incidence of ATEs with EYLEA in clinical trials was low (1.8%).Serious adverse reactions related to the injection procedure have occurred in less than 0.1% of intravitreal injections with EYLEA including endophthalmitis, traumatic cataract, and increased intraocular pressure.The most common adverse reactions (greater than or equal to 5%) reported in patients receiving EYLEA were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and increased intraocular pressure.Please see the full Prescribing Information for EYLEA, available online at www.regeneron.com/EYLEA-fpi.pdf. About the EYLEA? (aflibercept) Injection Global CollaborationRegeneron is collaborating with Bayer HealthCare on the global development of EYLEA.  Bayer submitted an application for marketing authorization in Europe for wet AMD in June 2011.Bayer HealthCare will market EYLEA outside the United States, where the companies will share equally the profits from any future sales of EYLEA.  Regeneron maintains exclusive rights to EYLEA in the United States.About Regeneron PharmaceuticalsRegeneron is a fully integrated biopharmaceutical company that discovers, invents, develops, manufactures, and commercializes medicines for the treatment of serious medical conditions.  Regeneron markets two products, ARCALYST® (rilonacept) Injection For Subcutaneous Use and EYLEA?
