Study Evaluating KTE-C19 in Pediatric and Adolescent Subjects With Relapsed/Refractory B-precursor Acute Lymphoblastic Leukemia
The primary objectives of this study are to evaluate the safety and efficacy of KTE-C19 in pediatric and adolescent participants with relapsed/refractory (r/r) B-precursor acute lymphoblastic leukemia (ALL).
