Study of Brexucabtagene Autoleucel (KTE-X19) in Participants With Relapsed/Refractory Mantle Cell Lymphoma (Cohort 1 and Cohort 2)
Purpose
The goal of this clinical study is to test how well the study drug, brexucabtagene autoleucel (KTE-X19), works in participants with relapsed/refractory (r/r) mantle cell lymphoma (MCL).
Condition
- Relapsed/Refractory Mantle Cell Lymphoma

- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
Up to 5 prior regimens for MCL. 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.
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.

Experimental Axicabtagene ciloleucel/brexucabtagene autoleucel (KTE-X19) |
Participants with relapsed/refractory mantle cell lymphoma (MCL) will receive conditioning chemotherapy (CTE) consisting of fludarabine 30 mg/m^2/day and cyclophosphamide 500 mg/m^2/day intravenous (IV) infusion for 3 days followed by a single infusion of axicabtagene ciloleucel at a targeted dose of 2 x 10^6 anti-CD19 chimeric antigen receptor (CAR) T cells/kg on Day 0 or brexucabtagene autoleucel (KTE-X19) at a targeted dose of 2 x 10^6 CAR T cells/kg, with a maximum dose of 2 x 10^8 anti-CD19 CAR T cells for participants ≥ 100 kg on Day 0 in Cohort 1 or brexucabtagene autoleucel at a targeted dose of 0.5 x 10^6 anti-CD19 CAR T cells/kg, with a maximum dose of 0.5 x 10^8 anti-CD19 CAR T cells for participants ≥ 100 kg on Day 0 in Cohort 2. |

Detailed Description
Study KTE-C19-102 enrolled participants with r/r MCL who have been treated with up to 5 prior regimens including a Bruton's tyrosine kinase inhibitor (BTKi) in Cohort 1 and Cohort 2. However, to fulfill FDA Postmarketing Requirement, Cohort 3 is added to the study. It will include participants with r/r MCL who have been treated with up to 5 prior regimens but have not received prior therapy with a BTKi. The primary analysis in Cohort 1 and Cohort 2 is already completed. Data for Cohort 3 will be analyzed separately. Therefore, details for Cohort 3 were registered separately (NCT04880434) on ClinicalTrials.gov as this cohort will not be part of the main study analysis. After the end of KTE-C19-102, subjects who received an infusion of anti-CD19 CAR T cells will complete the remainder of the 15-year follow-up assessments in a separate long-term follow-up study, KT-US-982-5968
