What Foselutoclax is
The most advanced senolytic in humans: an injected BCL-xL inhibitor that matched the biologic aflibercept on vision at most timepoints in a Phase 2b for diabetic macular edema.
Foselutoclax (Unity Biotechnology) kills senescent cells by blocking BCL-xL, the survival protein those cells depend on. Given as an eye injection, it improved vision by 5 or more letters at weeks 24 and 36 in the ASPIRE Phase 2b and was non-inferior to aflibercept at 9 of 10 timepoints, though investors judged the result mixed.
Mechanism: Inhibition of BCL-xL removes the anti-apoptotic signal senescent cells rely on, inducing their selective death.
Regulatory history: Investigational; Phase 2b
