"The preclinical studies to date provide very strong support for developing volociximab for ophthalmic indications. It represents a potential breakthrough for the treatment of AMD.”"

PRINCETON, N.J., CAMBRIDGE, Mass., & REDWOOD CITY, Calif.--(BUSINESS WIRE)--Ophthotech Corp. (Ophthotech), a privately held biopharmaceutical company focused on developing ophthalmic therapies for back-of-the-eye diseases, Biogen Idec Inc. (NASDAQ: BIIB) and PDL BioPharma, Inc. (NASDAQ: PDLI) today announced that they have entered into an exclusive worldwide licensing agreement for an anti-angiogenesis antibody to treat Age-Related Macular Degeneration (AMD). Under the terms of the agreement, Biogen Idec and PDL have granted Ophthotech worldwide development and commercial rights to all ophthalmic uses of volociximab (M200). Volociximab is an investigational monoclonal antibody targeting α5β1 integrin, a key protein involved in the formation of blood vessels, a process known as angiogenesis. Biogen Idec and PDL will each receive an equity position in Ophthotech as well as a combination of development milestone payments and royalties on future product sales. Other terms, including financial terms, related to the agreement have not been disclosed.

α5β1 integrin is a critical survival factor for proliferating endothelial cells involved in angiogenesis, said Samir Patel, MD, president and CEO of Ophthotech. "The preclinical studies to date provide very strong support for developing volociximab for ophthalmic indications. It represents a potential breakthrough for the treatment of AMD.

"There remains a significant unmet need in treating AMD, and we're pleased that Ophthotech, founded by leaders in the development of new therapeutics for this disease, has chosen to explore the potential of volociximab in AMD," said Faheem Hasnain, executive vice president, oncology and rheumatology strategic business unit, Biogen Idec.

"We believe the anti-angiogenesis properties of volociximab, coupled with Ophthotech's expertise in developing ophthalmic therapies, provide an excellent opportunity to maximize volociximab's value," said L. Patrick Gage, PhD, PDLs interim CEO.

Separately, Biogen Idec and PDL are co-developing volociximab in solid tumor cancers and the companies retain rights in all other indications pursuant to their September 2005 collaboration agreement.

About Age-Related Macular Degeneration (AMD)

AMD is the leading cause of blindness for people over the age of 55 in the United States and Europe. There are two forms of AMD, namely "dry" and "wet" AMD. The "wet" form is characterized by the growth of new blood vessels into the central region of the retina. These new vessels cause severe visual loss due to retinal damage caused by subsequent leakage and scar formation. Anti-VEGF therapies and photodynamic therapies have been approved for wet AMD. Dry AMD accounts for up to 90 percent of all cases of AMD. There is no approved therapy for "dry" AMD, which afflicts 8 million patients in the United States and an additional 8 million in Europe. Visual loss in "dry" AMD is typically not as severe as "wet" AMD, however, over time, dry AMD can progress to the wet form of the disease.
