Study of IBI354 Versus Investigator's Choice of Chemotherapy in Patients With Platinum-resistant Ovarian, Primary Peritoneal, or Fallopian Tube Cancer

Is NCT06834672 recruiting? Yes, currently enrolling (May 2026). This Phase 3 trial studies multiple treatments including IBI354 and paclitaxel/Gemcitabine/Liposomal doxorubicin for ovarian.

Phase 3RecruitingInnovent Biologics (Suzhou) Co. Ltd.NCT06834672Data as of May 2026

Treatment: IBI354 · paclitaxel/Gemcitabine/Liposomal doxorubicinThis is a multiregional, multicenter, randomized, open-label, phase III study to compare the efficacy, safety, and tolerability of IBI354 monotherapy with investigator's choice of chemotherapy (paclitaxel, gemcitabine, liposomal doxorubicin, or topotecan) in patients with HER2-expressing, platinum-resistant ovarian, primary peritoneal, or fallopian tube cancer. Participants with advanced ovarian, primary peritoneal, fallopian tube cancer who have failed or are intolerant to first-line or more platinum-based chemotherapy will be randomly assigned in a 2:1 ratio to two treatment arms: Experimental Arm: IBI354 monotherapy arm, 12 mg/kg IBI354 on Day 1 of each 3-week cycle; Control Arm: Investigator's choice chemotherapy (paclitaxel, gemcitabine, liposomal doxorubicin, or topotecan)
