Official title
Phase 1/1b Study of T-allo10 Infusion After HLA-Partially Matched Related or Unrelated TCR αβ+ T-cell/ CD19+ B-cell Depleted Allogeneic Hematopoietic Stem Cell Transplantation (αβ Depleted-HSCT) in Children and Young Adults Affected by Hematologic Malignancies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine the safety of a cell therapy, T-allo10, after αβdepleted-HSCT in the hopes that it will boost the adaptive immune reconstitution of the patient while sparing the risk of developing severe Graft-versus-Host Disease (GvHD). The primary objective of Phase 1a is to determine the recommended Phase 2 dose (RP2D) administered after infusion of αβdepleted-HSCT in children and young adults with hematologic malignancies. A Phase 1b extension will occur after dose escalation, enrolling at the RP2D for the T-allo10 cells determined in the Phase 1 portion to evaluate the safety and efficacy of infusion of T-allo10 after receipt of αβdepleted-HSCT. Additionally, Phase 1b aims to explore improvements in immune reconstitution. All participants on this study must be enrolled on another study: NCT04249830
