Brief Summary
This is a multicenter, double-blind, randomized, placebo-controlled phase Ⅱ study to evaluate the efficacy, safety, pharmacokinetics, and immunogenicity of YN-011 in subjects with overweight (27 kg/m2 ≤ BMI \< 30 kg/m2, with at least one comorbidity) or obesity (BMI ≥ 30 kg/m2, with or without comorbidities). The entire study period will consist of a 2-week screening period, a 22-week double-blind treatment period, and a 4-week off-treatment follow-up period

Study Arms (5)
Efsubaglutide 20 mg Quaque Week (QW)
EXPERIMENTALThe drug is administered once weekly, starting with a titration dose of 1 mg. The dose is up-titrated every 2 weeks in the sequence of 1 mg → 5 mg → 10 mg → 20 mg, reaching the target dose of 20 mg, the total treatment last for 22weeks.
Efsubaglutide 40 mg QW
EXPERIMENTALThe drug is administered once weekly, starting with a titration dose of 1 mg. The dose is up-titrated every 2 weeks in the sequence of 1 mg → 5 mg → 10 mg → 20 → 40mg, reaching the target dose of 40 mg, the total treatment last for 22weeks.
Efsubaglutide Alfa 40 mg Q2W
EXPERIMENTALThe drug is administered once weekly, starting with a titration dose of 1 mg. The dose is up-titrated every 2 weeks in the sequence of 1 mg → 5 mg → 10 mg → 20 → 40mg,when reaching to target dose of 40 mg, administered the drug every 2weeks. the total treatment last for 22weeks.
Efsubaglutide Alfa 80 mg QW
EXPERIMENTALThe drug is administered once weekly, starting with a titration dose of 1 mg. The dose is up-titrated every 2 weeks in the sequence of 1 mg → 5 mg → 10 mg → 20 → 40mg→ 80mg, reaching the target dose of 80 mg, the total treatment last for 22weeks.
Efsubaglutide Alfa 80 mg Q4W
EXPERIMENTALThe drug is administered once weekly, starting with a titration dose of 1 mg. The dose is up-titrated every 2 weeks in the sequence of 1 mg → 5 mg → 10 mg → 20 → 40mg→ 80mg,when reaching to target dose of 80 mg, administered the drug every 4weeks. the total treatment last for 22weeks.
