New combo aims to tame MALT lymphoma with less radiation damage

NCT ID NCT07554898

First seen Apr 30, 2026 · Last updated Jun 22, 2026 · Updated 11 times

Summary

This phase 2 trial is testing a new approach for adults with early-stage (I-II) MALT lymphoma, a slow-growing cancer. Participants first receive a very low dose of radiation (4 Gy total) over two days, then take a daily targeted drug called orelabrutinib for up to 6 months. The goal is to improve cancer remission while reducing long-term side effects like dry mouth or cataracts that can occur with standard radiation. The study will enroll 60 people across multiple centers to see how well the treatment works and how safe it is.

What this could mean

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

Active substance

Orelabrutinib (a targeted drug) and ultra-low-dose radiation therapy

What this could lead to

If successful, this approach could offer a more effective and less toxic first-line treatment for early-stage MALT lymphoma, potentially reducing long-term side effects from standard radiation.

What could go wrong

This is a small, early-phase (phase 2) study with only 60 participants. The combination may not work better than existing treatments, and orelabrutinib can cause side effects like infections or bleeding. Long-term benefits and risks are still unknown.
