This is an open-label, Part I/2/3 Phase 1 clinical study to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity of a single subcutaneous injection of CU-20401 in healthy Chinese population, and to recommend an appropriate dose for subsequent clinical studies.


In Part 1, 3 dose groups (dose group A1) were prespecified : 0.04 mg/dose; Dose Group A2 : 0.075 mg/dose; Dose Group A3 : 0.15 mg/dose). Eligible subjects were enrolled in the order from the low dose group to the high dose group (A1 → A2 → A3), and all subjects in the first dose group completed dosing.All examinations (vital signs, physical examination, laboratory tests, 12-lead ECG, abdominal wall color ultrasonography, etc.) will be performed during the dosing observation period and the follow-up period. Only after the investigator confirms that no subject meets the criteria for discontinuation of escalation, the next dose group can be started. Two subjects will be enrolled in each dose group for at least 24 h, and the remaining 4 subjects will not be enrolled until no safety events have occurred.

B2 (if any) to receive the established dose. All examinations (vital signs, physical examination, laboratory tests, 12-lead ECG, abdominal wall color ultrasonography, etc.) will be performed during the dosing observation period .All subjects may enter Part 3 of the study after the investigator confirms that all subjects have completed the visit on D7 and have no intolerable safety events.

Eligible subjects were sequentially enrolled in dose group C1 and dose group C2 (if any) to receive the established dose. All examinations (vital signs, physical examination, laboratory tests, 12-lead electrocardiogram, abdominal wall color ultrasonography, etc.) were performed during the dosing observation period .All subjects could end the study after the investigator confirmed that all subjects completed the visit on D29 of the follow-up period and no intolerable safety events occurred.
