This is a Study to Evaluate the Pharmacokinetics and Safety of IBI362 in Chinese Adolescents With Obesity

September 7, 2025 updated by: Innovent Biologics (Suzhou) Co. Ltd.

A Randomised, Double-blind, Placebo-controlled Trial to Assess Safety, Tolerability and Pharmacokinetics of IBI362 in Chinese Obese Adolescent Subjects

The study is a first-in-pediatric assessment of the safety, tolerability, and pharmacokinetic characteristics of multiple doses of IBI362 in Chinese adolescent subjects with obesity. It employs a multicenter, randomized, double-blind, and placebo-controlled trial design. The study plans to enroll 36 adolescents (aged ≥12 years and <18 years) with obesity who have experienced less than a 5% decrease in Body Mass Index (BMI) after at least 12 weeks of diet and exercise control.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 362-dose1-4mg
The starting dose for the subjects is 2 mg, administered once weekly for 4 consecutive weeks. If the subject shows good tolerability, the dose will then be escalated to 4 mg, also given once weekly, for another 8 weeks (with an escalation rate of increasing 2 mg every 4 weeks until reaching the target dose).
Drug: IBI362
IBI362 SA.QW
Experimental: 362-dose2-6mg
Subjects start at a dose of 2 mg, administered once weekly for 4 consecutive weeks. Following this, if the subject demonstrates good tolerability#, the dose will be escalated to 4 mg, also administered once weekly, for another 4 weeks. After observing the subject's tolerability again, if it remains favorable#, the dose will be further escalated to 6 mg, administered once weekly, for another 4 weeks (dosing will increase by 2 mg every 4 weeks until reaching the target dose of 6 mg)
Drug: IBI362
IBI362 SA.QW
Experimental: 362-dose3-Placebo
Administration is via subcutaneous injection once weekly; the mode and form of placebo administration are consistent with those of IBI362, with continuous dosing over a 12-week period.
Drug: IBI362 placebo
