About this study

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

This is a Phase 1 study of IBI3042, an investigational oral medicine being developed as a potential treatment for overweight and obesity. The study has two parts. Part A will evaluate single doses of IBI3042 in healthy adults. Part B will evaluate repeated doses for 13 weeks in adults with overweight or obesity. The main goal is to assess the safety and tolerability of IBI3042. The study will also evaluate how IBI3042 is processed in the body and explore its effects on body weight and other metabolic measures. Some participants will receive placebo, and some Part B groups will also receive orforglipron for comparison.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Orforglipron and IBI3042 in people with Overweight and Healthy Participants, run by Innovent Biologics (Suzhou) Co. Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 11 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yating Liu (0512-69566088, yating.liu@innoventbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Adverse Events (Part A) (time frame: through study completion, an average of 29 days). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2026.
