Official title

SHARP - Safely Delivered Targeted High-dose Irradiation Followed by Adoptive Immunotherapy with Regulatory and Conventional T Cells to Increase Potency of Hematopoietic Stem Cell Transplantation in High-risk Acute Leukemia

Overview

The study is a monocentric, interventional study that evaluates the efficacy of allogeneic HLA-matched or haploidentical transplantation consisting of an irradiation-based conditioning regimen coupled with donor Treg/Tcon adoptive immunotherapy for high-risk acute leukemia patients.

Interventions

  • Radiation total marrow/lymphoid irradiation
    Combination of 20 Gy TMLI with Treg/Tcon adoptive immunotherapy in allogeneic cell transplantation

Primary outcome measures

  • Number of participants free from disease 2 years after HSCT [Time frame: 2 years]
Secondary outcome measures (3)
  • Number of participants that have reached engraftment 45 days after HSCT [Time frame: 45 days]
  • Number of participants that developed grade ≥ 2 acute GvHD [Time frame: 2 years]
  • Number of participants free from chronic GvHD 2 years after HSCT [Time frame: 2 years]

Eligibility criteria

Inclusion criteria

  • Availability of a hematopoietic stem cell family donor (family or unrelated HLA-matched or HLA-haploidentical with the patient) suitable to be treated with G-CSF (10 mcg/kg/die) for a maximum of 7 days and able to tolerate 2 or more leukaphereses.
  • Age ≥ 18 and ≤ 65 years
