Could a daily aspirin boost ovarian cancer treatment?

NCT ID NCT05080946

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase study is testing whether taking a daily 325 mg aspirin alongside standard chemotherapy can reduce immune-suppressing cells in ovarian, fallopian tube, or peritoneal tumors. About 100 women will take either aspirin or a placebo for up to 5 cycles of chemo. The goal is to see if aspirin makes the tumor more vulnerable to the immune system, potentially improving treatment outcomes.

What this could mean

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

Active substance

Aspirin (325 mg daily)

What this could lead to

If it works, this could point toward a way to make standard chemotherapy more effective for ovarian cancer by reducing immune suppression in the tumor.

What could go wrong

This is a very early, small pilot study (Phase 1) looking at immune markers, not survival. Aspirin may not change tumor immune features, and results may not lead to a new treatment.
