Study on the Safety and Tolerability, Pharmacokinetics and Pharmacodynamics of SHR-2004 Injection in Adult Patients With Atrial Fibrillation

A Phase Ib Clinical Study to Evaluate the Safety and Tolerability, Pharmacokinetics, and Pharmacodynamics of Multiple Subcutaneous Injections of SHR-2004 Injection in Patients With Atrial Fibrillation

This study is an open-label Phase Ib clinical study with the primary objective of evaluating the safety and tolerability of multiple subcutaneous injections of SHR-2004 injection in patients with atrial fibrillation, and the secondary objective is to evaluate its pharmacokinetic (PK), pharmacodynamic (PD) and immunogenicity characteristics.
