Engineered donor cells take on tough lymphomas and leukemias
NCT ID NCT05878184
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tests SC291, a CAR T-cell therapy made from donor cells, in 16 adults with relapsed or refractory B-cell non-Hodgkin lymphoma or chronic lymphocytic leukemia. The goal is to check safety and see if the treatment can shrink tumors. Because it uses donor cells, it could be available faster than personalized therapies, but it also carries risks of immune reactions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SC291 (a type of CAR T-cell therapy made from donor cells)
- What this could lead to
- If it works, this could provide a new treatment option for people with hard-to-treat blood cancers who have run out of standard therapies.
- What could go wrong
- This is a very early (Phase 1) trial with only 16 participants, so safety and effectiveness are not yet proven. There are risks of serious side effects like cytokine release syndrome or immune reactions.
