Targeted Immunotherapy After Myeloablative TBI-Based Conditioning & AlloHCT in CAYA with High Risk T-Cell ALL & Lymphoma

Phase 1

Conditions
T-cell Acute Lymphoblastic Leukemia
T-Cell Acute Lymphoblastic Lymphoma
Interventions
Registration Number
NCT04972942
Lead Sponsor
New York Medical College
Brief Summary

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.

Detailed Description

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 (correlative studies/exploratory endpoints) to guide future selection of RP2D (15 patients)

Treatment Schedule:

1. Induction: DARA IV weekly x 8 doses (Weeks 1-8)

2. Consolidation: DARA IV every 2 weeks x 8 doses (Weeks 9-24)

3. Maintenance: DARA IV every 4 weeks (Stop at Day +270)
