Thalassemia Major
Conditions
Brief summary
The purpose of the study is to assess the safety and efficacy of haploidentical hematopoietic stem cell transplantation for patients with thalassemia major.
Detailed description
The only curative therapy for thalassemia major remains the replacement of the defective erythropoiesis by allogeneic hematopoietic stem cell transplantation(HSCT). However, this option is unavailable to many patients as a result of a lack of compatible donors.Haploidentical transplantation has been certified as a valuable alternative for hematological malignancy patients lacking a well-matched donor, with results comparable matched HLA-identical sibling donors or unrelated donors.The objective of this study is to test the feasibility of haploidentical HSCT for patients with thalassemia major.
