Using GM-CSF after transplant to improve recovery from blood cancers

Phase II Trial Evaluating the Efficacy and Safety of Sargramostim Post-Infusion of T-Replete HLA Mismatched Peripheral Blood Haploidentical Hematopoietic Stem Cells and With Post Transplant Cyclophosphamide

PHASE2 · Northside Hospital, Inc. · NCT04237623

This study is testing if a drug called GM-CSF can help people recovering from blood cancers after a specific type of stem cell transplant to improve their blood cell counts and reduce infection risks.

What this trial studies

This clinical trial investigates the use of GM-CSF (sargramostim) following haploidentical stem cell transplantation and post-transplant cyclophosphamide to enhance recovery rates of blood cell counts. The study aims to determine if GM-CSF can provide similar benefits to G-CSF while potentially reducing the risk of infectious complications associated with these transplants. Eligible participants include patients with various hematologic malignancies who have a matched related donor. The trial is designed to assess the safety and efficacy of this approach in improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients with hematologic malignancies who have a 5/10 to 8/10 matched related donor and a performance status of 70% or higher.

Not a fit: Patients with poor organ function, HIV-positive status, or severe allergic reactions to GM-CSF may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could lead to faster recovery of blood cell counts and lower infection risks for patients undergoing haploidentical stem cell transplants.

How similar studies have performed: Other studies have shown promising results with GM-CSF in similar contexts, suggesting potential for success in this approach.
