Engineered immune cells take aim at Hard-to-Treat leukemia
NCT ID NCT06927466
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This early-stage trial is testing an investigational therapy called B019, which uses a patient's own immune cells engineered to recognize and attack leukemia cells. The study focuses on people with B-cell acute lymphoblastic leukemia that has returned or not responded to standard treatments. The main goal is to assess the safety and tolerability of B019, while also looking at how well it works and how long any response might last.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- B019, a CAR-T cell therapy given as an intravenous infusion
- What this could lead to
- If successful, this could lead to a new treatment option that may put leukemia into remission for people who have run out of standard options.
- What could go wrong
- This is an early-phase trial with a small number of participants, so safety and effectiveness are not yet proven. CAR-T therapy can cause serious side effects, including cytokine release syndrome and neurological issues.
