REFRaME-01 STRO-002-GM3
A Phase 2/3 study to investigate the efficacy and safety of luveltamab tazevibulin versus IC chemotherapy in women with ovarian cancer (including fallopian tube or primary peritoneal cancers) expressing FOLR1.
Trial summary:
This is a randomized, multicenter, international, open-label, 2-part, Phase 2/3 study designed to assess the efficacy and safety of luveltamab tazevibulin versus IC chemotherapy in subjects with relapsed platinum-resistant epithelial ovarian cancer expressing FOLR1.
Part 1 will consist of 2 luveltamab tazevibulin dosing cohorts (Cohort A and Cohort B), with subjects randomized 1:1. Part 1 will be used to select the optimized dosing regimen.
Part 2 will further evaluate the efficacy and safety of the selected dosing regimen versus IC chemotherapy.
Luveltamab tazevibulin will be administered intravenously (IV) over a 1-hour infusion time every 3 weeks.
Receptor status / problem studied:
