Can a second CAR T-Cell infusion beat lymphoma that returns?

NCT ID NCT04419909

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This early-stage trial is testing whether a second infusion of a patient's own genetically modified immune cells (CAR T-cells) can safely treat B-cell lymphoma that has returned after an initial successful response. The study enrolls people with diffuse large B-cell or follicular lymphoma whose cancer came back at least six months after their first CAR T-cell treatment. The main goal is to check safety, with a secondary look at whether the cancer shrinks or disappears.

What this could mean

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

Active substance
a second infusion of the patient's own genetically modified immune cells (CAR T-cells) targeting CD19
What this could lead to
If it works, this could offer a second chance at remission for people whose lymphoma returns after an initial CAR T-cell success.
What could go wrong
This is a very early, small Phase 1 safety trial, so it is unclear whether retreatment will be effective or safe. Side effects from CAR T-cells can be severe, including cytokine release syndrome and neurological problems.
