  • Participants will be assessed to be in good health by the investigator, such as no clinically relevant abnormalities that will affect participant safety in the opinion of the investigator based on medical history, physical examination, clinical laboratory assessments (hematology, serum chemistry, coagulation, urinalysis, TH), and 12-lead ECG.

About this study

A Phase 1, double-blind, randomized study to evaluate the safety, tolerability, pharmacodynamics, and pharmacokinetics of single dose and multiple doses of CG-0416 in healthy participants. HongKong Curegene Innovation Co. Limited is developing the study drug CG-0416 as a potential new treatment for overweight and obesity. The purpose of this research is to investigate the safety, tolerability (if any side effects occur), pharmacokinetics (the amount of study drug or any of its breakdown products in your body) and pharmacodynamics (how the study drug affects your body), of single and multiple oral doses of a study drug called CG-0416.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CG-0416 in people with Overweight and Obesity, run by HongKong Curegene Innovation Co., Limited at 1 site in Australia.

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 7 inclusion and 31 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: opening soon, as of the sponsor's last update on 24 Jul 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 Australia. 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. 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 Philip Ryan, MD (61-0385939801, p.ryan@nucleusnetwork.com.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine number of participants with treatment-related adverse events as assessed by CTCAE v6.0 of single dose and multiple doses of CG-0416 in healthy participants. (time frame: up to 3 weeks). The study lists 3 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 24 Jul 2026.
