Phase 2 Study Assessing the Clinical Activity and Safety of Obecabtagene Autoleucel as a Consolidation in Patients With Newly Diagnosed High-risk B-cell Acute Lymphocytic Leukemia (ALL)
Trial Parameters
Brief Summary
The goal of this clinical research study is to learn if obecabtagene autoleucel (obe-cel) can help to control newly diagnosed, high-risk B-cell ALL when given as consolidation therapy. Consolidation therapy is given after the first phase of treatment.
