A Prospective Single-arm Trial on Human Leukocyte Antigen (HLA) Mismatched Unrelated Allogeneic Hematopoietic Stem Cell Transplantation
This study is a single center, prospective, single arm exploratory clinical trial that includes patients with hematological malignancies who are indicated for allogeneic hematopoietic stem cell transplantation (allo HSCT) but lack suitable donors. This project plans to use highly mismatched unrelated HLA mismatched donors. Ultimately, an unrelated human leukocyte antigen (HLA) mismatched allo HSCT transplantation plan will be established to improve the disease prognosis of this group of patients and truly enter the era of everyone has a donor for allo HSCT.
• Adult patients (18-60 years old) with hematological malignancies and indications for hematopoietic stem cell transplantation;
• Non blood donors without human leukocyte antigen (HLA) high-resolution typing ≥ 9/10, or those who have difficulty finding non blood donors due to urgent medical conditions;
• No suitable HLA matching haploidentical donor available;
• There are suitable unrelated HLA mismatched (HLA high-resolution typing\<9/10) donors;
• The subjects or their legal representatives shall sign an informed consent form before the start of the clinical study.
