A Single-arm Clinical Trial of IMGN853 in Chinese Adult Patients With Platinum-resistant, Epithelial Ovarian Cancer

This is a single-arm, phase III clinical trial of IMGN853 in Chinese adult patients with platinum-resistant, advanced high-grade epithelial ovarian, primary peritoneal or fallopian tube cancer with high expression of folate receptor-α. The objective of this study is to determine the efficacy of IMGN853 in platinum-resistant ovarian cancer (PROC) patients with high folate receptor alpha (FRα) expression. A total of 35 patients will be enrolled. All patients must have measurable disease (per Response Evaluation Criteria in Solid Tumors version 1.1, RECIST v1.1) at baseline and be eligible for receiving IMGN853. All patients will be treated with the IMGN853 monotherapy with a dose at adjusted ideal body weight (AIBW) of 6 mg/kg on Day 1 of every 3-week cycle (Q3W).
