Sofetabart mipitecan (Sofe-M) in combination with bevacizumab demonstrated a 79% confirmed objective response rate and 100% disease control rate, with similar activity observed across FR α expression levels Clinical activity with Sofe-M was maintained even in patients with prior PARP inhibitor exposure, patients who typically experience poor outcomes with platinum-based chemotherapy Sofe-M is currently being studied in both platinum-sensitive and platinum-resistant ovarian cancer in multiple Phase 3 studies as part of the FRAmework-01 master protocol INDIANAPOLIS, Oct. 24, 2026 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY ) today announced new Phase 1 data showing that its investigational folate receptor alpha (FRα) antibody-drug conjugate (ADC) sofetabart mipitecan (Sofe-M) plus bevacizumab achieved a confirmed objective response rate (cORR) of 79% and a disease control rate (DCR) of 100% in patients with platinum-sensitive ovarian cancer (PSOC). A cORR of 79% or higher was seen in both poly (ADP-ribose) polymerase inhibitor (PARPi)-treated and PARPi-naïve patients. These data will be shared in an oral presentation at the European Society for Medical Oncology (ESMO) Annual Congress in Madrid, Spain. FRα is expressed in almost all ovarian cancers, at much higher levels than in healthy tissue, making it a target that can help direct treatment to tumor cells. Sofe-M is an...
