Phase 3 Study Comparing AZD5335 to Mirvetuximab Soravtansine or Chemotherapy in Women with Platinum-Resistant High-Grade Ovarian, Fallopian Tube, or Peritoneal Cancer

What this Trial Is About

This research aims to evaluate the effectiveness of AZD5335 compared to standard treatments in women with high-grade, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer. The study focuses on whether AZD5335 improves progression-free survival PFS among participants with either high or low levels of folate receptor alpha FR. Approximately 1100 adult women will be enrolled and divided into two groups based on their FR levels. Participants will be randomized within each group to receive either AZD5335 or the relevant standard treatment. Those with high FR levels will receive AZD5335 or mirvetuximab soravtansine, while those with low FR levels will receive AZD5335 or a chemotherapy agent chosen by the investigator, including paclitaxel, pegylated liposomal doxorubicin, or topotecan. Treatments are given intravenously, and participants will continue treatment until disease progression or other reasons for stopping. During the study, participants will undergo regular tumor assessments to monitor disease status. Researchers will follow all participants over time to evaluate overall survival. Safety and efficacy data will be reviewed periodically by an independent committee. The primary outcome is progression-free survival, measured for up to about five years. The study completion is expected by late 2029.
