- Participant-recalled weights in the 3 months prior to screening are documented and used to calculate percentage weight change for the purpose of assessing the eligibility criterion (≤5%);
- Calibrated weights obtained at the site (e.g. Screening (D-35 to D-3 for SAD, D-35 to D-2 for MAD) and Check-in (D-2 for SAD, D-1 for MAD) visits) are compared to confirm stability between screening and check-in on the standardized, controlled scale;

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing SYH2082 Injection in people with Overweight or Obesity, run by CSPC ZhongQi Pharmaceutical Technology Co., Ltd. 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 42 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 23 Oct 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. 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 Clinical Trials Information Group officer (86-0311-69085587, ctr-contact@cspc.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Adverse Events as a measure of safety and tolerability of SYH2082 (time frame: SAD: Screening period up to day 57 MAD: Screening period up to day 85). 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 23 Oct 2026; AzTrials last refreshed its copy on 27 Oct 2026.
