What this trial studies

This first-in-human, open-label Phase 1 study uses dose-escalation and dose-optimization to find a safe and tolerable dose of MEN2501 as a single agent for adults with platinum-resistant ovarian, primary peritoneal, or fallopian tube cancer. The trial will measure safety, tolerability, pharmacokinetics, pharmacodynamics, and any signs of antitumor activity. Participants will receive escalating doses at the study site with regular safety labs, imaging, and PK/PD sampling to guide dose decisions. Cohorts may expand at recommended doses to further characterize preliminary activity and side effects.

Who should consider this trial

Good fit: Ideal candidates are adults with histologically confirmed high-grade serous ovarian cancer, primary peritoneal cancer, or fallopian tube cancer whose disease is platinum-resistant (not platinum-refractory) and who meet protocol health and laboratory criteria.

Not a fit: Patients with primary platinum-refractory disease, non-eligible tumor histologies, significant organ dysfunction, or inability to travel to the study site are unlikely to benefit from this trial.

Why it matters

Potential benefit: If MEN2501 proves safe and active, it could provide a new treatment option that shrinks tumors or slows disease progression in patients with platinum-resistant ovarian cancer.

How similar studies have performed: MEN2501 is being tested in humans for the first time, so there are no prior human data for this agent, while other experimental therapies in platinum-resistant ovarian cancer have shown mixed results.
