Original description

The goal of this study is to learn about the safety and tolerability of IBI3042, an investigational oral drug that activates the glucagon-like peptide-1 (GLP-1) receptor. The study will also assess how IBI3042 moves through the body and explore its effects on body weight and related measures. Researchers will evaluate whether single and multiple oral doses of IBI3042 can be administered with acceptable safety and tolerability.Read full original descriptionShow less

An Exploratory Study of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single-Dose IBI3042 in Healthy or Overweight Participants and Multiple-Dose IBI3042 in Overweight or Obese Participants

The goal of this study is to learn about the safety and tolerability of IBI3042, an investigational oral drug that activates the glucagon-like peptide-1 (GLP-1) receptor. The study will also assess how IBI3042 moves through the body and explore its effects on body weight and related measures. Researchers will evaluate whether single and multiple oral doses of IBI3042 can be administered with acceptable safety and tolerability.

The study has two parts. In Part A, healthy or overweight participants will receive a single oral dose of IBI3042 or placebo. In Part B, overweight or obese participants will receive multiple oral doses of IBI3042 or placebo over 29 days. Participants will be assigned to different dose groups, and dose escalation will be guided by safety, tolerability, and available drug concentration data from earlier groups.

Participants will undergo safety assessments and blood sampling during the study. These assessments will include medical examinations, vital signs, laboratory tests, and electrocardiograms. In Part B, researchers will also assess changes in body weight, body mass index, waist circumference, and other metabolic measures.

Inclusion: Aged 18 to 55 years, inclusive; For Part A: BMI ≥20 and<28 kg/m\^2 and body weight ≥50 kg; For Part B: BMI ≥24 and ≤40 kg/m\^2, with stable body weight during the 3 months prior to screening; Female participants of childbearing potential and male participants with female partners of childbearing potential must agree to use highly effective contraception during the study and for 90 days after the last dose; Able and willing to comply with study procedures and voluntarily provide written informed consent.

Exclusion: Use of medications that may significantly affect gastrointestinal motility, appetite, or drug absorption within 3 months prior to screening; Use of prescription or over-the-counter medications, dietary supplements, or herbal medicines within 2 weeks or 5 half-lives prior to screening, except as permitted by the protocol; Participation in another drug or medical device clinical study within 3 months prior to screening or within 5 half-lives of the investigational drug, as applicable; Known or suspected hypersensitivity to any component of the study drug or to GLP-1 receptor agonists; History of diabetes or abnormal glycemic parameters at screening; Personal or family history of thyroid C-cell carcinoma or multiple endocrine neoplasia syndrome type 2 (MEN 2A or 2B), or calcitonin ≥20 ng/L at screening; History of acute or chronic pancreatitis, or clinically significant pancreatic enzyme elevation at screening; Clinically significant hematologic, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, or neurologic disease that may increase study-related risk or interfere with study assessments; History of malignancy within 5 years, except for basal cell or squamous cell skin cancer; Any other condition that, in the investigator's opinion, makes the participant unsuitable for participation in the study; Clinically significant abnormalities in physical examination or laboratory tests at screening.
