Double-barreled CAR t therapy takes aim at hard-to-treat myeloma

NCT ID NCT05431608

First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time

Summary

This phase 1 trial tests a new approach for people with multiple myeloma that has come back or stopped responding to at least three prior treatments. The study uses two different CAR T cell therapies—one targeting a protein called GPRC5D and another targeting BCMA—given together after a short course of chemotherapy. The goal is to find the safest dose and see if attacking the cancer from two angles can improve outcomes.

What this could mean

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

Active substance
CAR T cells targeting GPRC5D and BCMA
What this could lead to
If successful, this dual-target approach could offer a new treatment option for multiple myeloma that has stopped responding to standard therapies.
What could go wrong
This is an early phase 1 trial with only 15 participants, so safety and effectiveness are not yet established. CAR T therapy can cause serious side effects like cytokine release syndrome.
