SOUTH SAN FRANCISCO, Calif., Dec. 19, 2019 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (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).
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 profile predicts a competitive human intravitreal dosing only three or four times a year. ARVO presentation materials can be accessed on the Events and Presentations section of the Catalyst website.

This press release contains forward-looking statements that involve substantial risks and uncertainties. Such statements include statements about potential milestone payments and royalties, the potential uses and benefits of CB 2782-PEG to treat geographic atrophy or dry AMD, the potential for CB 2782-PEG to be a best-in-class therapy, and to have human dosing three or four times per year. Actual results or events could differ materially from the expectations disclosed in the forward-looking statements as a result of various important factors, including, but not limited to, the risk that development of CB 2782-PEG may be delayed or unsuccessful, that human trials will not replicate the results from animal studies, that potential adverse effects may arise from the testing or use of CB 2782-PEG, the risk that Biogen may cease development of CB 2782-PEG, competition and other risks described in the “Risk Factors” section of the Company’s quarterly report filed with the Securities and Exchange Commission on November 7, 2019, and in other filings with the Securities and Exchange Commission.
