Old drug, new hope: atovaquone tested against tough ovarian cancer

NCT ID NCT05998135

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This phase II trial tests whether atovaquone, a drug currently used to treat certain infections, can help control platinum-resistant ovarian cancer. The study enrolls 28 patients whose cancer has progressed within six months of their last platinum-based chemotherapy. Participants will take atovaquone by mouth and undergo regular scans and biopsies to see if the drug slows tumor growth.

Active substance

atovaquone

What this could lead to

If it works, this could offer a new treatment option for ovarian cancer that has stopped responding to standard platinum chemotherapy.

What could go wrong

This is a small, early-phase trial with only 28 participants. The drug is being tested for a new purpose, so it may not work against cancer, and side effects are not yet fully known.
