First Patient Enrolled in Regeneron and Bayer HealthCare VEGF Trap-Eye Phase 3 Program in Central Retinal Vein Occlusion
Regeneron received $20 million milestone payment from Bayer HealthCare with dosing of first patient
Phase 2 study of VEGF Trap-Eye in diabetic macular edema fully enrolled
TARRYTOWN, N.Y.--(BUSINESS WIRE)--Regeneron Pharmaceuticals, Inc. (NASDAQ:REGN) today announced that the first patient has been enrolled in the Phase 3 program of VEGF Trap-Eye for the treatment of central retinal vein occlusion (CRVO), a leading cause of blindness in adults. Regeneron received a $20 million milestone payment from Bayer Healthcare that was triggered by the dosing of the first patient in the CRVO program. Regeneron also announced that enrollment in the Phase 2 DA VINCI study of VEGF Trap-Eye in diabetic macular edema (DME) has been completed and data are expected during the first half of 2010.
VEGF Trap-Eye, an investigational drug, is being developed by Regeneron and Bayer HealthCare AG for the potential treatment of eye diseases, including the neovascular form of age-related macular degeneration (wet AMD), DME, and CRVO.
The Phase 3 program in CRVO consists of two multinational, one-year clinical studies. The COPERNICUS (COntrolled Phase 3 Evaluation of Repeated iNtravitreal administration of VEGF Trap-Eye In Central retinal vein occlusion: Utility and Safety) study is being led by Regeneron and the GALILEO (General Assessment Limiting InfiLtration of Exudates in central retinal vein Occlusion with VEGF Trap-Eye) study is being led by Bayer HealthCare. Patients in both studies will receive six monthly intravitreal injections of either VEGF Trap-Eye at a dose of 2 milligrams (mg) or sham control injections. The primary endpoint of both studies is improvement in visual acuity versus baseline after six months of treatment. At the end of the initial six months, patients will be dosed on a PRN (as needed) basis for another six months. All patients will be eligible for rescue laser treatment. Results from both CRVO studies are expected in 2011.
In wet AMD, Regeneron and Bayer Healthcare are evaluating VEGF Trap-Eye in two ongoing Phase 3 studies, known as VIEW 1 and VIEW 2 (VEGF Trap: Investigation of Efficacy and Safety in Wet age-related macular degeneration). Enrollment in these trials is expected to be completed by the end of this year, and data are expected in late 2010.
Regeneron maintains exclusive rights to VEGF Trap-Eye in the United States. Bayer HealthCare has exclusive rights to market VEGF Trap-Eye outside the United States, where the companies will share equally in profits from any future sales of VEGF Trap-Eye.
About CRVO
Over 100,000 people in the United States are estimated to suffer from CRVO, a disease for which there is no current treatment that can be considered standard of care. CRVO is caused by obstruction of the central retinal vein that leads to a back up of blood and fluid in the retina, resulting in retinal injury and loss of vision. The retina can also become "ischemic" (starved for oxygen), resulting in the growth of new abnormal blood vessels that can cause further vision loss and more serious complications. Release of VEGF contributes to increased vascular permeability in the eye and abnormal new vessel growth. It is believed that anti-VEGF treatment may help decrease vascular permeability and edema and prevent the growth of abnormal new blood vessels in the retina in patients with CRVO.
About DME
Diabetic Retinopathy (DR) can lead to significant vision impairment and is a major complication of diabetes. Diabetic Macular Edema (DME) is a common complication of DR that involves fluid collection in the macula. DME is the most prevalent cause of moderate visual loss in patients with diabetes.
DME is a leading cause of adult blindness in the developed world. Severe visual loss is caused by a combination of fluid build-up around the retina and the unnatural growth of blood vessels in the back of the eye.
About VEGF Trap-Eye
Vascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body whose normal role is to trigger formation of new blood vessels (angiogenesis) to support the growth of the body's tissues and organs. It has also been associated with the abnormal growth and fragility of new blood vessels in the eye and vascular permeability and edema. VEGF Trap-Eye is a fully human, soluble VEGF receptor fusion protein that binds all forms of VEGF-A along with the related Placental Growth Factor (PlGF). Investigational VEGF Trap-Eye is a specific blocker of VEGF-A and PlGF that has been demonstrated in preclinical models to bind these growth factors with greater affinity than their natural receptors.
