(Nasdaq: CBIO), today announced it has entered into a global license and collaboration agreement with Biogen Inc. (Nasdaq: BIIB) for the development and commercialization of pegylated CB 2782 (CB 2782-PEG) for the potential treatment of geographic atrophy (GA) associated dry age-related macular degeneration (dry AMD).\n Under the terms of the agreement, Biogen will receive an exclusive worldwide license to develop and commercialize CB 2782-PEG and Catalyst’s other anti-C3 proteases for the potential treatment of dry AMD. Catalyst will perform pre-clinical and manufacturing activities and Biogen will be solely responsible for funding the pre-clinical and manufacturing activities and performing Investigational New Drug (IND)-enabling activities, worldwide clinical development, and commercialization. Catalyst will receive a $15 million upfront payment and is eligible to receive up to $340 million in clinical, regulatory, and commercial milestone payments plus future tiered royalties based on net sales. \"We believe Biogen is an excellent collaborator for our anti-C3 ophthalmology program,” said Nassim Usman, Ph.D., president and chief executive officer of Catalyst. “Geographic atrophy, an advanced form of dry AMD, can have a devastating impact on vision, affects over a million people in the United States and is a significant market opportunity with no approved therapies. CB 2782-PEG could offer clinically meaningful efficacy through prolonged and complete suppression of C3, a clinically validated target in GA.” Catalyst presented preclinical data on CB 2782-PEG at the 2019 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) in Vancouver, British Columbia. The comprehensive study demonstrated CB 2782-PEG’s potential for efficacy and improved convenience. Key highlights included an increase in CB 2782’s ocular half-life following PEGylation without compromising activity. Importantly, a single intravitreal injection of 125 μg CB 2782-PEG in non-human primates eliminated greater than 99% of the C3 from the vitreous humor for at least 28 days. This pharmacodynamic pro...
