简要总结
This study is designed as a Phase Ib/II trial. The phase Ib cohort will enroll patients with severe aplastic anemia (SAA) who have failed to respond to intensified immunosuppressive therapy. In contrast, the phase II cohort will include newly diagnosed and treatment-naïve patients with SAA. A Safety Review Committee (SRC), chaired by the principal investigators, will be established to oversee patient safety throughout the study. Suppose the Phase Ib results demonstrate acceptable safety and tolerability. In that case, the data will be submitted to the Ethics Committee for review, and, upon approval, the study will advance to Phase II.
Phase Ib uses a 3+3 dose-escalation design with two cohorts: 150 mg golidocitinib orally every other day (low dose) or once daily (high dose). Phase II is a single-arm trial with Simon's two-stage optimal design.

Experimental
Phase Ib:
Dose escalation follows the "3+3" principle. Participants will receive golidocitinib 150 mg every other day (qod) or 150 mg once daily (qd) for 12 consecutive weeks. Based on the clinical trial data obtained (e.g., safety, maximum tolerated dose), the recommended Phase II dose (RP2D) will be determined following discussion by the SRC.
Phase II:
Participants will receive golidocitinib at the RP2D in combination with intensive immunosuppressive therapy for 12 consecutive weeks.
intensive immunosuppressive therapy regimen:
- Porcine anti-lymphocyte globulin (pALG): 25 mg/kg/day or Rabbit anti-thymocyte globulin (rATG): 3.0 mg/kg/day × 5 days,
- Cyclosporine: 3-5 mg/kg/day,
- Eltrombopag: 15 mg/day.
干预措施: Golidocitinib Capsules (Drug)
