NCT06845592

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Number of participants free from disease 2 years after HSCT

    The primary objective of the study is to reduce the incidence of disease relapse after irradiation-based conditioning regimen and Treg/Tcon adoptive immunotherapy-based allogeneic transplantation from HLA-matched or haploidentical donors in high-risk acute leukemia patients.

    2 years

Secondary Outcomes (3)

  • Number of participants that have reached engraftment 45 days after HSCT

    45 days

  • Number of participants that developed grade ≥ 2 acute GvHD

    2 years

  • Number of participants free from chronic GvHD 2 years after HSCT

    2 years

Study Arms (1)

TMLI based contioning and Treg/Tcon adoptive immunotherapy in allogeneic cell transplantation

EXPERIMENTAL

All enrolled patients will receive a 20Gy-TMLI based conditioning regimen followed by the infusion of donor graft and Treg/Tcon adoptive immunotherapy

Radiation: total marrow/lymphoid irradiation

Interventions
