High-dose irradiation followed by immunotherapy for high-risk leukemia patients

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

Not applicable Interventional University Of Perugia · NCT06845592

This study is testing a new treatment that combines high-dose radiation with special immune cells to see if it helps patients with high-risk leukemia do better after a stem cell transplant.

What this trial studies

This study evaluates the effectiveness of a treatment approach that combines high-dose total marrow and lymphoid irradiation with adoptive immunotherapy using donor Treg and conventional T cells for patients with high-risk acute leukemia. It focuses on patients who are undergoing allogeneic hematopoietic stem cell transplantation and have specific genetic risks or active disease. The study aims to enhance the potency of the transplantation process to improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 65 with acute myeloid leukemia or acute lymphoblastic leukemia who are eligible for allogeneic hematopoietic cell transplantation.

Not a fit: Patients with low-risk leukemia or those who do not meet the eligibility criteria for transplantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve survival rates and outcomes for patients with high-risk acute leukemia.

How similar studies have performed: While this approach is innovative, similar studies involving high-dose irradiation and immunotherapy have shown promise in improving outcomes for leukemia patients.
