Combining Umbilical Cord Blood Transplantation with Reduced-Toxicity Conditioning for High-Risk Blood Cancers

Total Body Irradiation/ Fludarabine/ Busulfan/ Cyclophosphamide (TFBC) Combined With Umbilical Cord Blood Transplantation (UCBT) in the Treatment of High-risk Malignant Hematological Diseases

Not applicable Interventional The First Affiliated Hospital of Soochow University · NCT05929092

This study is testing a new way to treat high-risk blood cancers like leukemia by using a gentler conditioning process before patients receive umbilical cord blood transplants to see if it helps them recover better.

What this trial studies

This study investigates the effectiveness of a reduced-toxicity myeloablative conditioning regimen combined with umbilical cord blood transplantation (UCBT) in treating patients with high-risk malignant hematological diseases such as leukemia and multiple myeloma. The approach aims to improve patient outcomes by enhancing neutrophil engraftment and reducing treatment-related complications. Patients will undergo a conditioning regimen that includes busulfan, cyclophosphamide, and fludarabine before receiving UCBT. The study will evaluate the safety and efficacy of this combined treatment in a clinical setting.

Who should consider this trial

Good fit: Ideal candidates are patients aged 14 to 70 with high-risk malignant hematological diseases who meet specific health criteria.

Not a fit: Patients with low-risk hematological diseases or those who do not meet the health criteria for the study may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates and quality of life for patients with high-risk malignant hematological diseases.

How similar studies have performed: Previous studies have shown promising results with similar approaches, particularly in improving engraftment and survival rates in patients undergoing umbilical cord blood transplantation.
