Summary

This pilot study tests whether adding the blood thinner tinzaparin to standard chemotherapy can improve outcomes for women with advanced ovarian cancer. About 40 participants will receive either chemotherapy plus tinzaparin or chemotherapy alone. The main goal is to see if tinzaparin affects a key tumor marker called CA-125.

What this could mean

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

Active substance: Tinzaparin (Innohep), a blood thinner
What this could lead to: If it works, this could point toward a way to make chemotherapy more effective for advanced ovarian cancer.
What could go wrong: This is a very small, early pilot study. It may not show a clear benefit, and the blood thinner carries a risk of bleeding.
