Eksperimentel: Zuberitamab-Orelabrutinib combination therapy
This study is designed as a non-randomized, single-arm, open-label clinical trial.
Patients with refractory immune-related cytopenia, including immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA), are intended for enrollment.
The treatment regimen and schedule are as follows: anti-CD20 monoclonal antibody (Zuberitamab): 100 mg per dose on Days 1, 8, 15, and 22; BTK inhibitor (Orelabrutinib): 50 mg once daily (qd) from Day 1 to Day 90.
|
This is a novel combination regimen of anti-CD20 monoclonal antibody plus BTKi, specifically designed for patients with refractory immune-related cytopenia.
