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)

Description

A Phase I trial to determine the safety of targeted immunotherapy with daratumumab (DARA) IV after total body irradiation (TBI)-based myeloablative conditioning and allogeneic hematopoietic cell transplantation (HCT) for children, adolescents, and young adults (CAYA) with high risk T-cell acute lymphoblastic leukemia (T-ALL) or T-cell lymphoblastic lymphoma (T-LLy). Pre- and post-HCT NGS-MRD studies will be correlated with outcomes in children, adolescents, and young adults with T-ALL undergoing allogeneic HCT and post-HCT DARA treatment. The study will also evaluate T-cell repertoire and immune reconstitution prior to and following DARA post-HCT treatment and correlate with patient outcomes.Total body irradiation (TBI)-based myeloablative allogeneic hematopoietic stem cell transplantation (HCT) using best available donor. Daratumumab (DARA) treatment post-HCT: Phase 1: 3 dose levels to determine safety (15 patients) Dose expansion cohort (DEC): Further evaluation of PK and PD (cor
