A Study of CD19 Targeted CAR T Cell Therapy in Pediatric Patients With Relapsed or Refractory B Cell Acute Lymphoblastic Leukemia (B ALL) and Aggressive Mature B-cell Non-Hodgkin Lymphoma (B NHL)
A Single-Arm, Open-Label, Multicenter, Phase 1b/2 Study Evaluating the Safety and Efficacy of AUTO1 (Obecabtagene Autoleucel [Obe-cel]) in Pediatric Patients With CD19-positive Relapsed/Refractory (R/R) B Cell Acute Lymphoblastic Leukemia (B ALL) or R/R Aggressive Mature B Cell Non-Hodgkin Lymphoma (B NHL).

Summary
This is a Phase 1b/2 study to evaluate the safety and efficacy of autologous T cells engineered with a chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 in pediatric patients with relapsed or refractory (r/r) B cell acute lymphoblastic leukemia (B ALL) and r/r B cell Non-Hodgkin lymphoma (B NHL).
Eligibility
Inclusion Criteria7
- \< 18 years old at screening
- ≥ 6 kg body weight at screening
- Pediatric patients with r/r B ALL
- r/r CD19-positive aggressive mature B including the B NHL subtypes: i) diffuse large B cell lymphoma, ii) Burkitt's lymphoma, iii) primary mediastinal large B cell lymphoma, iv) high-grade B cell lymphoma (not otherwise specified).
- Karnofsky (age ≥ 10 years) or Lansky (age \< 10 year) performance status score ≥ 50%.
- In participants with B ALL, local documentation of CD19 expression on leukemic blasts in the BM, peripheral blood, or cerebrospinal fluid or biopsy done no more than 30 days prior to consent.
- Adequate renal, hepatic, pulmonary, and cardiac function.
Exclusion Criteria6
- Diagnosis of chronic myelogenous leukemia in lymphoid blast crisis.
- History or presence of clinically relevant central nervous system (CNS) pathology unrelated to CNS leukemia.
- Presence of active or uncontrolled fungal, bacterial, viral, or other infection requiring systemic antimicrobials for management.
- Received prior (\< 3 months before obe cel infusion) stem cell transplantation.
- Prior CD19 targeted therapy other than blinatumomab.
- Experienced Grade ≥ 3 neurotoxicity following blinatumomab.
Interventions
Following lymphodepletion with chemotherapy (cyclophosphamide and fludarabine) patients will be treated with anti-CD19 chimeric antigen receptor (CAR) T cells
