Assessing Hematopoietic Cell Transplantation for Myelofibrosis

Prospective Assessment of Allogeneic Hematopoietic Cell Transplantation in Patients With Myelofibrosis

Observational Center for International Blood and Marrow Transplant Research · NCT02934477

This study is trying to see if patients with myelofibrosis who receive a stem cell transplant do better than those who didn't have the transplant.

What this trial studies

This observational study aims to compare outcomes between patients with myelofibrosis who undergo allogeneic hematopoietic cell transplantation (HCT) and a cohort of historical non-HCT controls. Eligible patients include those with primary myelofibrosis, post-essential thrombocythemia myelofibrosis, or post-polycythemia vera myelofibrosis, aged 55 or older with intermediate-2 or high-risk disease. Data will be collected from multiple US academic centers, focusing on both HCT recipients and historical controls to evaluate the effectiveness of the treatment. The study will enroll approximately 650 patients receiving HCT and collect data from around 2,400 historical controls.

Who should consider this trial

Good fit: Ideal candidates are patients aged 55 or older with intermediate-2 or high-risk myelofibrosis.

Not a fit: Patients with low-risk myelofibrosis or those not eligible for HCT may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of HCT for patients with myelofibrosis, potentially improving treatment options.

How similar studies have performed: Previous studies have shown promising outcomes for HCT in similar patient populations, indicating a potential for success in this approach.
