About this trial
Therapy with chimeric antigen receptor T (CAR-T) cells has demonstrated activity against refractory hematologic malignancies, however not all tumors respond or remain in response to CD19 targeted CAR-T cells. We posit that CAR-T cells expressing BAFF (BAFF CAR-T cells) can become another strategy to treat refractory hematologic malignancies, even after relapse following cluster of differentiation antigen 19 (CD19) targeting CAR-T treatment. This phase 1 study will evaluate safe dose and provide initial signal of the activity of BAFF CAR-T cells against refractory hematologic malignancies using a single lymphodepletion regimen and using a BAFF CAR-T cell manufacturing process.
Eligibility criteria
Qualifiers
Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia and/or thrombocytopenia. Cutoff levels of Hb <10 g/dL or platelet counts <100 × 10^9/L are generally regarded as indication for treatment.
Massive (i.e., ≥6 cm below the left costal margin) or progressive or symptomatic splenomegaly.
Massive nodes (i.e., ≥10 cm in longest diameter) or progressive or symptomatic lymphadenopathy.
Symptomatic or functional extranodal involvement (e.g., skin, kidney, lung, spine, etc.).
Disqualifiers
Second active (i.e., currently requires antineoplastic therapy) non-B cell lineage malignancy, other than non-melanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast).
Renal failure requiring regular dialysis.
Uncontrolled pulmonary disease or infection.
Cardiovascular disorders including symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmias, myocardial infarction or stroke (including transient ischemic attack, or other ischemic event) within 6 months prior to registration.
