New drug cocktail shows promise for tough ovarian cancers

NCT ID NCT03462342

Summary

This study tested a combination of two drugs, AZD6738 and olaparib, in 123 women with recurrent ovarian cancer. The goal was to see if the combo is safe and how well it shrinks tumors or delays cancer growth. Participants had either platinum-sensitive or platinum-resistant cancer, and some had already stopped responding to PARP inhibitors. The trial looked at side effects, tumor response, and how long patients lived without their cancer getting worse.

What this could mean

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

Active substance

AZD6738 (ATR inhibitor) and olaparib (PARP inhibitor)

What this could lead to

If successful, this combination could offer a new treatment option for women with recurrent ovarian cancer, potentially slowing disease progression even after other treatments have failed.

What could go wrong

This is a Phase 2 trial with 123 participants, so results are still early. The combination may cause significant side effects, and not all patients may respond, especially those resistant to PARP inhibitors.
