Two-Drug attack on tough lymphoma shows promise in early trial

NCT ID NCT03278782

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether combining two drugs—pembrolizumab (Keytruda), which helps the immune system fight cancer, and romidepsin (Istodax), which blocks cancer cell growth—can safely treat peripheral T-cell lymphoma that has returned or not responded to prior therapy. The trial involves 39 participants and is in early phases (I/II) to check side effects and effectiveness. The goal is to see if the combo works better than either drug alone.

What this could mean

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

Active substance
pembrolizumab (Keytruda) and romidepsin (Istodax)
What this could lead to
If successful, this combination could offer a new treatment option for patients with peripheral T-cell lymphoma that has come back or stopped responding to other therapies.
What could go wrong
This is an early-phase trial with only 39 participants, so results may not apply to all patients. The combination may cause significant side effects, and it is not yet known if it works better than existing treatments.
