Can a common antioxidant boost CAR T-Cell therapy for lymphoma?
NCT ID NCT05081479
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests whether adding N-Acetylcysteine (N-AC), an antioxidant, to standard CAR T-cell therapy (Yescarta) is safe for people with lymphoma. Nine participants receive different doses of N-AC to find the highest dose with few side effects. The goal is to see if N-AC can improve the tumor environment and make the CAR T cells work better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- N-Acetylcysteine (N-AC) given with axicabtagene ciloleucel (Yescarta) CAR T-cell therapy
- What this could lead to
- If it works, this could make CAR T-cell therapy more effective for lymphoma by improving the tumor environment.
- What could go wrong
- This is a very early phase 1 trial with only 9 participants, so it's mainly checking safety. The benefit is uncertain, and side effects from the combination are unknown.
