Experimental drug aims to boost CAR-T power against lymphoma
NCT ID NCT07361224
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests whether adding a drug called CLS-015 to standard CAR-T cell therapy can help people with large B-cell lymphoma whose disease is stable or getting worse. CLS-015 works by breaking down NETs, which are immune-trapping webs that may block CAR-T cells. The study will enroll 12 adults and focus on safety, not yet on cure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CLS-015 (a drug that breaks down NETs) given alongside CAR-T cell therapy
- What this could lead to
- If it works, this could improve how well CAR-T therapy fights large B-cell lymphoma, especially in patients whose disease is stable or progressing.
- What could go wrong
- This is a very early Phase 1 trial with only 12 participants, so safety and effectiveness are not yet proven. The added drug may cause side effects or not improve outcomes.
