Chemo-Free combo for lymphoma shows promise in early trial

NCT ID NCT04268277

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tested a combination of two drugs, pembrolizumab (Keytruda) and rituximab (Truxima), in 22 people with marginal zone lymphoma, a type of blood cancer. The goal was to see if this chemotherapy-free approach could control the disease with fewer side effects than standard chemo. The study was terminated early, so the full results are not yet clear.

Active substance
Pembrolizumab (Keytruda) and Rituximab (Truxima)
What this could lead to
If successful, this could provide a chemotherapy-free treatment option for marginal zone lymphoma, potentially reducing side effects while controlling the disease.
What could go wrong
The trial was terminated early with only 22 participants, so results are limited. It is a small phase 2 study, and the combination may not be as effective as standard chemo or could cause unexpected side effects.
