Modified second transplantation for patients with graft failure

Second Haploidentical Transplantation with Modified Regimen for Graft Failure After the First Allogeneic Stem Cell Transplantation

Not applicable Interventional Peking University People's Hospital · NCT06512545

This study is testing a new approach to a second stem cell transplant for patients who didn't fully recover after their first transplant to see if it helps them get better, especially with their platelet counts.

What this trial studies

This study investigates a modified regimen for second allogeneic stem cell transplantation in patients who have experienced graft failure after their first transplant. The aim is to enhance hematopoietic reconstitution and improve recovery outcomes, particularly focusing on patients who have not fully recovered their platelet counts. It is a prospective, single-arm study that evaluates the safety and efficacy of this new approach. The study includes patients with hematological malignancies who meet specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates are patients aged 14 and older with hematological malignancies who have experienced graft failure within 180 days of their first allogeneic stem cell transplantation.

Not a fit: Patients with active infections, organ dysfunction, or severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery rates and outcomes for patients suffering from graft failure after stem cell transplantation.

How similar studies have performed: Previous studies have shown encouraging results with similar approaches, but this specific modified regimen is novel.
