A single intravitreal injection of 125 μg CB 2782-PEG achieved complete, rapid and sustained pharmacodynamic inhibition (>99%) of complement factor 3 (C3) in non-human primates (NHP), supporting dosing three to four times a year
Data support CB 2782-PEG’s potential as a best-in-class anti-C3 ocular therapy
SOUTH SAN FRANCISCO, Calif. and BOULDER, Colo., April 29, 2019 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (NASDAQ: CBIO), and Mosaic Biosciences today announced the presentation of new data on pegylated CB 2782 (CB 2782-PEG), Catalyst’s preclinical anti-C3 candidate being developed for the treatment of geographic atrophy (GA) associated dry age-related macular degeneration (dry AMD) at the 2019 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO), being held in Vancouver, British Columbia, from April 28 - May 2, 2019.
The poster, entitled: “Pegylated CB 2782: A Complement Factor C3-Inactivating Protease and Potential Long-Acting Treatment for Dry AMD,” was presented by Eric Furfine, Ph.D., Mosaic’s Head of Ophthalmology. The data demonstrate CB 2782-PEG’s potential for a superior efficacy profile and improved convenience over clinical candidates in Phase 3 development. A copy of the presentation materials can be accessed on the Events and Presentations section of the Catalyst website. Key highlights include:
“Geographic atrophy, an advanced form of dry AMD, affects over a million people in the United States and can have a devastating impact on vision. Currently there are no approved treatment options for these patients. C3 is the only clinically validated target for GA in dry AMD, therefore CB 2782-PEG’s ability to nearly eliminate C3 with intravitreal dosing three or four times a year has the potential to be a best-in-class therapy,” said Eric Furfine, Ph.D., Head of Ophthalmology at Mosaic.
In 2017 Catalyst and Mosaic entered into a strategic collaboration to develop novel protease-based anti-C3 intravitreal products. Catalyst retains global commercial rights for all collaboration products and Mosaic receives product sublicense fees and/or milestone payments and royalties.
