HID-HSCT Versus IST as First-line Treatment for SAA
Starting soon · Not applicable
Conditions studied: Aplastic Anaemia
In brief
This study aims to compare the efficacy and safety of HLA-haploidentical hematopoietic stem cell transplantation (HLA-haplo HSCT) versus optimal immunosuppressive therapy (IST) as first-line treatments for severe aplastic anemia (SAA) through a real-world cohort design. The selection of treatment regimens for subjects is based on clinical decision-making in real-world practice, comprehensively considering factors including patient age, donor matching status, comorbidities, and treatment preferences, with non-randomized group allocation.

Who can join
Age: 14 and older, up to 70. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
