Summary

This phase 2 trial is testing whether a two-year maintenance treatment with lenalidomide and rituximab can prevent relapse in patients with primary central nervous system lymphoma who have responded to initial chemotherapy but are not eligible for a stem cell transplant. The study will enroll 30 participants and track how long they live without the cancer progressing. The goal is to improve survival in a group that currently has very poor outcomes after relapse.

What this could mean

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

Active substance

lenalidomide and rituximab (drugs)

What this could lead to

If successful, this maintenance therapy could help prevent relapse and extend survival for patients with primary CNS lymphoma who cannot undergo a stem cell transplant.

What could go wrong

This is a small, early-phase study (30 participants) with no control group. The drugs may cause side effects, and it is not yet known if they will meaningfully improve outcomes.
