The study included adult patients ≥18 years old with SAA and TD-NSAA who had no HLA-matched sibling donors or were not suitable for first-line allogeneic hematopoietic stem cell transplantation due to age, complications, patient wishes, etc. After admission, they were treated with standard IST combined with rhTPO for at least 28 days. After discharge, the sequential treatment of EPAG-PFOS (with an initial dose of 150mg/d) was continued for 2 months (8 weeks), and the follow-up was conducted until the 6th month (24 weeks). It was compared with the historical cohort previously treated with IST combined with EPAG to explore the short-term efficacy and safety of this treatment regimen.
