Inclusion criteria

  • Overweight/obese Chinese subjects, who voluntarily sign the Form (ICF), can receive subcutaneous injection, fully understand the content, process and possible adverse reactions of the trial, and are able to follow the regulations on and restrictions specified in this protocol.
  • Male or female, 18 to 50 years of age at signing the ICF (both inclusive).
  • Weight ≥ 50 kg and (BMI) within 24-33 kg/m2 (both ends inclusive) at screening.
  • Subjects of with no birth plan from the signing of ICF to 3 months after the last dose, willingness to take effective measures, and no plan for sperm or ovum donation. Females of childbearing potential must not be lactating and must have negative results of pregnancy tests at screening and Visit 2 (prior to enrollment).

Exclusion criteria

Exclusion Criteria:

  • Subjects with a previous or existing history of heart, liver, kidney, gastrointestinal tract, respiratory system, nervous system, psychiatric disease, malignant tumor and other diseases that are judged by the investigator to have an impact on pharmacokinetics and safety evaluation.
  • History or existing diseases that increase the risk of subjects, such as hypoglycaemia, acute or chronic pancreatitis, pancreatic injury, history of symptomatic gallbladder disease; cholelithiasis with high risk of acute biliary pancreatitis at screening (e.g., silt-like lithiasis, gallbladder ≤ 5 mm in diameter and bile duct stone, etc.).
  • Subjects with previous or existing diseases that significantly affect drug absorption, metabolism or excretion, such as history of active peptic ulcer or haemorrhage, inflammatory bowel disease, abnormal gastric emptying (such as gastric paresis or pyloric stenosis, gastric outlet obstruction), long-term use (continuous for ≥ 1 week) of drugs that affect gastrointestinal motility (including but not limited to domperidone, mosapride, macrolides).
  • Subjects with severe infection or unexplained infection within 4 weeks before screening.
  • Major surgery within 6 months prior to screening, or scheduled surgery or hospitalization during the study.
  • History of drug abuse prior to screening; or positive results for drug abuse at screening.
  • Subjects who used nicotine-containing products within 3 months prior to screening or are screened positive for nicotine in urine.
  • Other factors that make subjects unqualified to participate in this trial as judged by the Investigator.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Oct 2024; primary completion for Mar 2025, 4 months later.

Of 452 industry-sponsored phase 1 interventional studies under Diabetes Mellitus, Type 2, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 11. This study's planned 4 months is below that.

Counting every sponsor, half of 514 studies reached it within 6 months; a quarter within 2 and three quarters within 14.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 1, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
