The researchers are doing this study to find out whether obecabtagene autoleucel (obe-cel) is an effective treatment for people with B-cell acute lymphoblastic leukemia (ALL) that is in complete remission (CR, meaning all signs of cancer are gone) with no measurable residual disease (MRD-negative, meaning there are no detectable cancer cells). Participants in this study will have received past treatment for their B-cell ALL, and their disease will be in MRD-negative CR for the first time (first MRD-negative CR).
Inclusion Criteria: * Diagnosis of CD19+ B-cell ALL. * Both Ph-negative and Ph-positive are allowed * Patients with EMD must have detectable disease in the bone marrow (by flow cytometry or molecular methods) in order to follow MRD. * Patients aged ≥ 40 years at time of screening A. * Patients aged 30-39 years (at time of Screening A) are allowed in the presence of high-risk comorbidities or poor tolerability of chemotherapy (e.g. history or experienced pancreatitis with therapy, BMI ≥40kg/m2, underlying liver disease precluding safer administration of pediatric inspired regimens, any fu…
Given as infusion. Obe-cel dose 1: Obe-cel will be administered 3 days (+/- 1 day) after completion of lymphodepleting chemotherapy, allowing a minimum of 48 hour washout from the last dose of lymphodepleting chemotherapy.
