1. Study population:It is applicable to male participants with genetically confirmed and clinically confirmed Duchenne muscular dystrophy (DMD), aged between 6 and 10 years. 2. Research period:The main research period of this clinical study is one year. Participants were tested during the baseline period and were followed up on days 0, 7, 14, 21, 60, 120, 200, and 360. 3.

Safety laboratory evaluation, laboratory safety monitoring, including hematology, blood biochemistry, urine analysis (including troponin I, CK and CK - MB) and blood coagulation function, as well as complement. All common medication will be recorded. All adverse events, including abnormal complete blood cell count results, will be continuously tracked until they are resolved or stabilized. Only treatment-related adverse events (TEAE) will be summarized. AEs will be based on MedDRA and organ systems are recorded and archived. The classification and terminology related to AEs will be described according to the version of CTCAE v6.0.
