New drug combo shows promise for Tough-to-Treat lymphomas

NCT ID NCT03259503

First seen Jun 26, 2026 · Last updated Jul 31, 2026 · Updated 3 times

Summary

This phase 1 trial tested the safety and best dose of olaparib when added to high-dose chemotherapy for 50 patients with lymphomas that returned or didn't respond to treatment. All patients were scheduled for a stem cell transplant. The goal was to see if the combination could work better than chemotherapy alone, but the main focus was on side effects and dosing.

What this could mean

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

Active substance
Olaparib (a PARP inhibitor) combined with high-dose chemotherapy (busulfan, gemcitabine, melphalan) and sometimes rituximab
What this could lead to
If successful, this combination could offer a new treatment option for patients with hard-to-treat lymphomas who are undergoing a stem cell transplant.
What could go wrong
This is an early phase 1 trial with only 50 participants, so the main goal was safety and dosing, not effectiveness. The added drugs may increase side effects, and it's unclear if the combination works better than standard care.
