A Clinical Study Evaluating the Safety and Efficacy of GT801 Injection in Adult Patients With Relapsed/Refractory CD19-positive B-cell Hematologic Malignancies and Autoimmune Hemolytic Anemia

The goal of this clinical study is to evaluate the safety and efficacy of GT801 injection in adult patients with relapsed/refractory CD19-positive B-cell hematologic malignancies and autoimmune hemolytic anemia. Interim analysis conducted when 2 patients complete primary endpoint measurement.

CD20 Monoclonal Antibody Combined With BTK Inhibitor for the Treatment of Refractory Immune-related Cytopenia

This study aims to utilize anti-CD20 monoclonal antibodies to eliminate peripheral B cells and reduce the mechanism of autoantibody production, as well as combine the mechanism of BTK inhibitors (BTKi) blocking the B cell receptor signaling pathway and inhibiting B cell activation and proliferation, for the treatment of refractory immune-related cytopenia. In this study, it includes the salvage treatment of immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA), expecting to achieve a synergistic and enhancing effect. This study aims to select Zuberitamab, a human-mouse chimeric anti-CD20 monoclonal antibody, and the BTKi Orelabrutinib as combination therapy options. The clinical efficacy of the Zuberitamab-Orelabrutinib combination therapy (overall response rate, duration of sustained remission) will be evaluated, along with its safety profile (including infections, bleeding, cardiac toxicity), to provide a theoretical basis for their combined use in treating refractory immune-related thrombocytopenia (ITP and AIHA).

A Multicenter, Prospective, Randomized Controlled Study Comparing Glucocorticoid Combined With Sirolimus With Monotherapy of Glucocorticoid in the Treatment of Newly Diagnosed Mild Autoimmune Hemolytic Anemia

This study is a prospective, multicenter, randomized controlled trial. A total of 216 adult patients with newly diagnosed wAIHA were planned to be included and randomly assigned in a 1:1 ratio to the experimental group (glucocorticoid combined with sirolimus) or the control group (glucocorticoid monotherapy). The initial dose of sirolimus in the experimental group was 1mg/d, adjusted according to the blood drug concentration. The target concentration was 4-12ng/mL, and the treatment course was 6 months. Both groups of hormones were gradually reduced according to the standard protocol. All patients were followed up for 24 months, and the differences between the two groups at endpoints such as the hormone-free sustained response rate at the 12th month were compared.

Orelabrutinib in the Treatment of Relapsed/Refractory AIHA

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. Patients who respond and tolerate the drug well may continue treatment for up to 52 weeks or longer to observe long-term efficacy and safety. 2. cAIHA Treatment Regimen: Group C (150mg group): Orelabrutinib 150 mg, orally, once daily. The treatment course is at least 12 weeks. Patients who respond and tolerate the drug well may continue treatment for up to 52 weeks or longer to observe long-term efficacy and safety.
