New combo aims to fight recurrent brain tumors

NCT ID NCT05345002

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests a combination of two drugs—all-trans retinoic acid (ATRA) and retifanlimab—in 55 people with recurrent IDH-mutant glioma, a type of brain tumor. The goal is to see if the combo can shrink tumors or slow their growth. Participants take ATRA pills for 14 days each cycle and get retifanlimab infusions every 28 days, continuing until the disease worsens or side effects become too severe.

What this could mean

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

Active substance

All-trans retinoic acid (ATRA) and retifanlimab (a PD-1 inhibitor)

What this could lead to

If it works, this could offer a new treatment option for people with recurrent IDH-mutant glioma, potentially shrinking tumors and delaying progression.

What could go wrong

This is a small, early-phase trial (55 people) with no control group. The combination may not work better than existing treatments, and side effects from immunotherapy and ATRA could be significant.
