Summary

This study is a randomized, open-label, active-controlled, multicenter phase III clinical trial.

It is planned to enroll 300 subjects with platinum-resistant recurrent epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer with HER2 expression. The randomization will be stratified according to the following factors: 1) HER2 immunohistochemistry (IHC) expression status (HER2 IHC 1+ versus HER2 IHC 2+/3+); 2) whether the subject has previously received vascular endothelial growth factor/vascular endothelial growth factor receptor (VEGF/VEGFR) inhibitors such as bevacizumab (yes versus no).

Subjects will be randomly assigned in a 1:1 ratio to receive either the experimental treatment group (SHR - A1811) or the control treatment group (chemotherapy chosen by the investigator, namely liposomal doxorubicin, paclitaxel, topotecan, or gemcitabine).

DRUG

SHR-A1811

Injection SHR - A1811 (hereinafter referred to as SHR - A1811) is an antibody - drug conjugate (ADC) targeting the HER2 protein, independently developed by Suzhou Shengdeya Biopharmaceutical Co., Ltd. (hereinafter referred to as the "sponsor"). It is composed of a recombinant humanized anti - HER2 IgG1 monoclonal antibody (SHR - 1805) conjugated with a small molecule component, SHR169106.

DRUG

Chemotherapy

The treatment regimens for the control group are as follows: Liposomal doxorubicin: Administered intravenously on Day 1 of each 4 - week treatment cycle at a dose of 40 mg/m². Paclitaxel: Given intravenously on Days 1, 8, 15, and 22 of each 4 - week treatment cycle at a dose of 80 mg/m² per administration. Topotecan: Intravenously infused on Days 1, 8, and 15 of each 4 - week treatment cycle at a daily dose of 4 mg/m². Gemcitabine: Infused intravenously on Days 1 and 8 of each 3 - week treatment cycle at a daily dose of 1000 mg/m².
