Targeted immunotherapy for high-risk T-cell leukemia and lymphoma in young patients

Phase I Trial of Targeted Immunotherapy With Daratumumab Following Myeloablative TBI-Based Conditioning and AlloHCT in Children, Adolescents and Young Adults With High Risk T-Cell Acute Lymphoblastic Leukemia and Lymphoma (ALLO-T-DART)

Phase 1 Interventional New York Medical College · NCT04972942

This study is testing a new treatment called daratumumab for young patients with high-risk T-cell leukemia and lymphoma to see if it is safe and helps improve their outcomes after a stem cell transplant.

What this trial studies

This Phase I trial evaluates the safety of daratumumab (DARA) administered after total body irradiation (TBI)-based myeloablative conditioning and allogeneic hematopoietic cell transplantation (HCT) in children, adolescents, and young adults with high-risk T-cell acute lymphoblastic leukemia (T-ALL) or T-cell lymphoblastic lymphoma (T-LLy). The study includes pre- and post-HCT assessments of minimal residual disease (MRD) and immune reconstitution to correlate these factors with patient outcomes. Participants will receive DARA in a structured treatment schedule, including induction, consolidation, and maintenance phases. The trial aims to identify the optimal dosing and safety profile of DARA in this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates are children, adolescents, and young adults aged 0-39 years with high-risk T-cell ALL or relapsed T-cell lymphoma who are eligible for allogeneic stem cell transplantation.

Not a fit: Patients with uncontrolled infections, prior stem cell transplants, or significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and survival rates for young patients with high-risk T-cell leukemia and lymphoma.

How similar studies have performed: While targeted immunotherapy is a growing field, this specific approach combining TBI and DARA in this patient population is novel and has not been extensively tested in prior studies.
