Lilly's early ovarian cancer study found disease controlled in every patient.
Eli Lilly's experimental drug, sofetabart mipitecan (Sofe-M), showed promising results in a Phase 1 study for ovarian cancer, with a 100% disease control rate in patients. Sofe-M, an FRα-targeting antibody-drug conjugate, is being studied in multiple Phase 3 trials. The company aims to address the unmet need in platinum-sensitive ovarian cancer treatment.
