IBI3042: a first-in-human dose-finding study in adults with overweight or obesity

Official title: A Phase I Study to Evaluate Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Characteristics of Single-Dose IBI3042 in Healthy Participants and Multiple-Dose IBI3042 in Overweight or Obese Participants

Run by Innovent Biologics (Suzhou) Co. Ltd. · NCT07793019 · Data updated 2026-11-12

This is a Phase 1 trial testing IBI3042 in healthy adults and adults with overweight or obesity to see if it is safe and tolerable and to get a sense of how it works in the body, with some groups comparing to a placebo and, in Part B, to orforglipron.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-55 with BMI 20-29.9 for Part A; BMI 24-40 with stable weight for 3 months for Part B.

Probably not a fit

Participants who do not meet BMI criteria, have contraindicated medical histories, or who experience adverse effects may not receive direct benefit.

What this trial studies

This is a two-part Phase 1 study of IBI3042. Part A will test single doses in healthy adults to assess safety and how the drug is processed by the body. Part B will test repeated dosing for 13 weeks in adults with overweight or obesity, evaluating safety, tolerability, pharmacokinetics, and effects on weight and metabolic parameters. Some participants will receive placebo, and Part B may include a comparator group receiving orforglipron. The study aims to establish initial safety signals and dosing guidance for future trials.

Why it matters

Potential benefit: Participants may experience weight-related metabolic insights and safety data that could support future development of IBI3042 for overweight or obesity.

How similar studies have gone: Previous studies of related GLP-1 pathway approaches have shown safety signals and weight-related effects in early phases, but results for IBI3042 specifically are not yet established.
