Engineered immune cells show promise against tough lymphoma
NCT ID NCT02601313
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 study tested a single infusion of brexucabtagene autoleucel (KTE-X19), a CAR T-cell therapy, in 105 patients with relapsed or refractory mantle cell lymphoma. The treatment aims to help the body's own immune cells recognize and attack cancer. Results showed that many patients achieved a response, offering hope for those who have run out of standard options.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- brexucabtagene autoleucel (KTE-X19) CAR T cells
- What this could lead to
- If successful, this could provide a powerful treatment option for patients with hard-to-treat mantle cell lymphoma, potentially leading to long-term remission.
- What could go wrong
- This is a phase 2 trial with a relatively small number of participants. CAR T-cell therapy can cause serious side effects like cytokine release syndrome and neurological problems. Not all patients responded, and long-term durability is still being studied.

Key Inclusion Criteria: Up to 5 prior regimens for Mantle cell lymphoma. Prior therapy must have included: * Anthracycline or bendamustine-containing chemotherapy and * Anti-CD20 monoclonal antibody therapy and * Ibrutinib or acalabrutinib At least 1 measurable lesion Platelet count ≥ 75,000/uL Creatinine clearance (as estimated by Cockcroft Gault) \> or = to 60 mL/min Cardiac ejection fraction ≥ 50%, no evidence of pericardial effusion as determined by an echocardiogram (ECHO), and no clinically significant electrocardiogram (ECG) findings Baseline oxygen saturation \>92% on room air. Key Exclusion Criteria: * Known history of infection with human immunodeficiency virus (HIV) or hepatitis B (HBsAG positive) or hepatitis C virus (anti-HCV positive). A history of hepatitis B or hepatitis C is permitted if the viral load is undetectable per standard serological and genetic testing * History of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, cerebral edema, posterior reversible encephalopathy syndrome, or any autoimmune disease with central nervous system (CNS) involvement * Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring IV antimicrobials for management. Note: Other protocol defined Inclusion/Exclusion criteria may apply.
