Linperlisib in the Treatment of aPRCA

Linperlisib 40 mg, orally, once daily. Following 2 weeks of treatment, efficacy was assessed. If the reticulocyte count remained \<20×10⁹/L, the dose was escalated to 60 mg, once daily. After an additional 2 weeks of therapy, a second efficacy assessment was performed. Patients failing to achieve partial response (PR) underwent further dose escalation to 80 mg, once daily. Treatment was discontinued if PR was not attained after 8 weeks at the maximum dose. Responding patients maintained therapy at their effective dose level. The core study period comprised 12 weeks, with responders continuing treatment at the investigator's discretion.
