Foselutoclax is an investigational new drug that is being evaluated for the treatment of age-related eye diseases, particularly diabetic macular edema (DME) and wet age-related macular degeneration (AMD). Developed by Unity Biotechnology, this senolytic compound acts as a potent inhibitor of Bcl-xL, a protein that senescent cells rely on for survival.^[1] Foselutoclax is designed to selectively eliminate senescent cells in the retina, potentially addressing the underlying causes of vision loss in these conditions.^[2]
