A Three-Part Phase 3 Study of Sofetabart Mipitecan in Participants With Platinum-Resistant (Part A) and Platinum-Sensitive (Parts B and C) Ovarian Cancer
United States, Australia, Austria1,630 participantsStarted 2025-10-22
Plain-language summary
This is a clinical study that has three parts. It is testing a potential new medicine called Sofetabart Mipitecan (Sofe-M) for people with certain types of ovarian, peritoneal, and fallopian tube cancers. Part A enrolls participants with platinum-resistant cancer, meaning their disease progressed during or within six months of platinum-based chemotherapy. Parts B and C enroll participants with platinum-sensitive cancer, whose disease responded and remained controlled for at least six months after completing platinum treatment. The researchers want to find out if Sofe-M works better than the standard treatments that doctors use now and to better understand how safe it is. Each participant's time in the study will depend on how they respond to the treatment.

Inclusion Criteria:
Part A, B, and C:
* Have histologically confirmed high-grade serous or endometrioid ovarian, primary peritoneal, or fallopian tube cancer.
* Have confirmed availability of tumor tissue block or slides
* Have radiographic progression on or after most recent line of systemic anticancer therapy
* Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
* Have measurable disease per RECIST v1.1
Part A:
* Have platinum-resistant disease, defined as radiographic progression less than or equal to (≤)6 months of the last administration of platinum therapy.
* Have previously received 1 to 3 prior lines of systemic cytotoxic therapy. Up to 4 lines of prior cytotoxic therapy is allowed if one of those lines is mirvetuximab soravtansine.
* Have received prior bevacizumab treatment, unless documented contraindication or intolerance.
* Have received treatment with a poly (ADP-ribose) polymerase inhibitor (PARPi) if known to have a somatic or germline breast cancer gene (BRCA) mutation, if clinically indicated, unless documented contraindication or intolerance.
Part B and C:
* Have relapsed after first-line platinum-based chemotherapy and have platinum-sensitive disease defined as radiographic progression greater than (\>)6 months of their last administration of platinum therapy
* Have previously received 1 to 2 prior lines of systemic cytotoxic chemotherapy
Part B:
\- Have previously received a PARPi, per local product label, with progression…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
