1. wAIHA Treatment Regimen: Group A (50mg group): Orelabrutinib 50 mg, orally, once daily. After 4 weeks of treatment, if still transfusion-dependent or hemoglobin increase is \< 20 g/L, the dose may be increased to 100 mg qd. Treatment can be discontinued if ineffective at 12 weeks.
Group B (100mg group): Orelabrutinib 100 mg, orally, once daily. The treatment course is at least 12 weeks. Treatment can be discontinued if ineffective at 12 weeks.
