研究目的:

1.评价Nb120抗体应用于发热伴血小板减少综合征患者的临床安全性; 2.评价Nb120抗体是否降低发热伴血小板减少综合征患者重症率和病死率; 3.评价Nb120抗体是否能够促进发热伴血小板减少综合征患者临床症状的改善和缩短住院时间; 4.评估Nb120抗体在发热伴血小板减少综合征患者中的药效动力学(PD),包括对病毒载量的影响、血小板数量的变化、白细胞数量的变化以及其他实验室指标的改善情况; 5.测定Nb120抗体在发热伴血小板减少综合征患者体内的药代动力学(PK),包括半衰期、清除率、分布容积和生物利用度等。  

Objectives of Study:

1.To evaluate the clinical safety of Nb120 antibody in patients with Severe Fever with Thrombocytopenia Syndrome (SFTS). 2.To determine whether Nb120 antibody reduces the incidence of severe disease and mortality in patients with SFTS. 3.To assess whether Nb120 antibody promotes clinical symptom improvement and shortens hospitalization time in patients with SFTS. 4.To evaluate the pharmacodynamic (PD) effects of Nb120 antibody in patients with SFTS, including its impact on viral load, platelet count, white blood cell count, and other laboratory parameters. 5.To characterize the pharmacokinetics (PK) of Nb120 antibody in patients with SFTS, including half-life, clearance, volume of distribution, and bioavailability.
