| Measure | Time frame | Description |
|---|---|---|
| Safety and tolerability of single dose administration of CM559 in healthy male subjects: Adverse events (AEs), physical examinations, vital signs, 12-lead electrocardiograms (ECGs), magnetic resonance imaging (MRI), laboratory tests, etc. | Up to 99 Days | All adverse events (AEs) collected from all subjects from the time of signing the informed consent form (ICF) to the completion of the study (or early withdrawal), including clinical manifestations, severity, occurrence time, end time, treatment measures, and outcomes, as well as their correlation with the investigational drug. Any clinically significant abnormalities found during the physical examinations, vital signs examination, ECGs examinations and laboratory tests.
