New CAR t therapy targets tough lymphoma

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Informed Consent: Signed informed consent by the participant or legally authorized representative. 2. Age \& Performance Status: * Age ≥ 18 years * ECOG performance status ≤ 2 3. Diagnosis \& Disease Criteria: * Histologically confirmed B-NHL, including LBCL, MCL, and FL/MZL subtypes meeting specified prior treatment conditions. * BAFF-R expression on lymphoma cells required. 4. Measurable Disease: Tumor ≥1.5 cm on CT/PET scan or evidence of disease in blood, BM, GI, skin, or spleen. 5. Prior CAR T-cell Therapy: Allowed if ≥ 3 months since last treatment and CD19 CAR-T persistence \< 5% before leukapheresis. 6. Organ Function \& Laboratory Criteria: * Hematologic: ANC ≥ 1000/μL, Platelets ≥ 75,000/μL (exceptions for BM involvement). * Liver Function: Bilirubin ≤ 1.5x ULN (except Gilbert's), AST/ALT \< 3x ULN. * Renal Function: CrCl ≥ 50 mL/min. * Cardiac \& Pulmonary: LVEF ≥ 45%, QTcF ≤ 480 ms, O₂ saturation \> 91% on room air. 7. Infectious Disease Screening: Seronegative for HIV, active HBV, active HCV (or undetectable viral load if positive). 8. Reproductive Considerations: * Negative pregnancy test for females of childbearing potential. * Use of effective contraception or abstinence through 3 months post-treatment. Exclusion Criteria: 1. Prior Therapies \& Transplants: * Prior allogeneic SCT. * Autologous SCT \< 6 months before leukapheresis. * Concurrent systemic steroids or chronic immunosuppressant use. 2. Disease-Specific Exclusions: * Cardiac lymphoma involvement. * Need for urgent therapy due to tumor-related complications (e.g., bowel obstruction). 3. Medical Conditions: * Active autoimmune disease requiring immunosuppressants. * Primary immunodeficiency. * Cardiac conditions, including NYHA Class III/IV heart disease, arrhythmia, recent MI (≤ 6 months), stroke (≤ 6 months), or significant VTE (≤ 6 months). * Neurologic conditions, including prior optic neuritis, CNS inflammatory diseases, or seizure disorders. * History of malignancy, unless resected/treated with curative intent or in remission for ≥ 3 years. * Uncontrolled systemic infections or active CNS lymphoma. 4. Pregnancy \& Breastfeeding: Females who are pregnant or nursing. 5. Other Considerations: * Investigator-determined safety concerns. * Potential noncompliance with study procedures.
