3. července 2026 aktualizováno: Shanghai Yinnuo Pharmaceutical Technology Co., Ltd.

A Randomized, Double-blind, Placebo-controlled Phase Ib Study to Evaluate the Safety,Tolerability, Pharmacokinetics and Pharmacodynamics of Multiple Doses of Efsubaglutide Alfa in Chinese Adolescents With Obesity

This is a Phase Ib, randomized, double-blind, placebo-controlled clinical study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of Efsubaglutide Alfa Injection following multiple-dose administration in Chinese adolescent participants with obesity.

Přehled studie

Detailní popis

The prevalence of obesity in adolescents is rising and threatening physiological and psychological health. Different from adults with obesity, there is still no approved drug to manage the obesity in adolescents, In order to provide the therapeutical option earlier, the weight-reduction study in obese adolescents is planned. The primary objective of this Phase Ib study is to evaluate the safety, tolerability, and pharmacokinetic (PK) characteristics of multiple doses of Efsubaglutide Alfa at different dose levels in Chinese adolescent participants with obesity. The secondary objectives include the evaluations of the pharmacodynamic (PD) effects, PK-PD relationship , and immunogenicity of multiple doses of Efsubaglutide Alfa at different dose levels. This randomized, double-blind, placebo-controlled, parallel-group study will enroll a total of 36 adolescent participants aged 12 to 17 years with obesity . 36 participants will be randomized in a 3:1 ratio to receive Efsubaglutide Alfa or placebo administered subcutaneously once weekly (QW) for up to 12 weeks. Safety will be monitored throughout the study by assessment of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), adverse events of special interest (AESI), laboratory parameters, vital signs, and 12-lead electrocardiograms.
