Cancer-Killing virus shows promise in tough ovarian cancer trial

NCT ID NCT05281471

First seen Jun 24, 2026 · Last updated Jul 10, 2026 · Updated 2 times

Summary

This Phase 3 study tests whether a modified virus called Olvi-Vec, given with chemotherapy and bevacizumab, can help women with ovarian cancer that no longer responds to platinum drugs. About 186 participants will receive either the virus combination or standard chemotherapy. The goal is to see if the virus can make the cancer sensitive to platinum again and slow disease progression.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Olvi-Vec (a modified virus that targets and kills cancer cells), followed by platinum chemotherapy and bevacizumab
What this could lead to
If successful, this could offer a new treatment option for women with hard-to-treat ovarian cancer that has stopped responding to platinum-based chemotherapy.
What could go wrong
This is an early Phase 3 trial with only 186 participants, so results may not apply to all patients. The virus-based therapy may cause side effects or fail to improve outcomes compared to current treatments.
