As of May 27, 2025, there is no publicly available information about a collaboration between Biogen and City Therapeutics to develop RNA interference (RNAi) therapies. While both companies are active in the biotech field, this specific partnership has not been reported.
City Therapeutics has been focusing on strategic collaborations with other companies, like Bausch + Lomb, in developing RNAi-based treatments for retinal diseases, including geographic atrophy. Meanwhile, Biogen has forged partnerships, such as the one with C4 Therapeutics, to innovate in neuroscience drug discovery, Reuters reported.
The absence of a partnership between Biogen and City Therapeutics for RNAi therapies does not overshadow the strategic alliances each company has formed in their respective areas. These partnerships highlight ongoing efforts to advance medical treatments through novel biotechnological approaches.
