Eli Lilly Unveils Promising Phase 1 Data for New FRα Targeting ADC in Platinum-Resistant Ovarian Cancer at 2025 ASCO Annual Meeting

Eli Lilly and Company has announced new Phase 1 clinical trial data for its investigational folate receptor alpha (FRα) targeting antibody-drug conjugate $(ADC)$, LY4170156, at the 2025 ASCO Annual Meeting. The trial focused on women with heavily pre-treated platinum-resistant ovarian cancer, including those previously treated with mirvetuximab soravtansine. The findings revealed an encouraging safety profile and anti-tumor activity across varying doses and FRα expression levels, with a preliminary overall objective response rate of 55% at a potential recommended Phase 2 dose of 4 mg/kg. The ADC comprises an Fc-silent, FRα specific humanized monoclonal antibody linked to exatecan, a topoisomerase I inhibitor. These results suggest potential for expanding treatment options for ovarian cancer patients and will be further investigated in registrational Phase 3 clinical trials.
