An Exploratory Study of Single-Dose and Multiple-Doses IBI3042 in Healthy, Overweight, or Obese Participants

NCT07802899 | Not Yet Recruiting Phase 1

• 1 other identifier: CIBI3042T001
• Study Type: interventional
• Target: 94
• Locations: 1 country
• Sites: 1

Brief Summary

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.

• 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.
• Use of medications that may significantly affect gastrointestinal motility, appetite, or drug absorption within 3 months prior to 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.

Study Design

• Study Type: interventional
• Phase: phase 1
• Allocation: RANDOMIZED
• Masking: TRIPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, OUTCOMES ASSESSOR
• Masking Details: Participants, care providers and outcome assessors are blinded to treatment assignment. Most investigators remain blinded. Selected unblinded investigators (dose-escalation committee members) have access to treatment allocation for safety evaluation and dose-escalation decision-making.
• Purpose: TREATMENT
• Intervention Model: SEQUENTIAL
• Sponsor Type: OTHER
• Responsible Party: SPONSOR INVESTIGATOR
• PI Title: Chief Physician

Model Details: Sequential group-assignment design, including single ascending dose (SAD) phase and multiple ascending dose (MAD) phase. Cohort A0 receives IBI3042 in a non-randomized manner. Participants in other cohorts are randomized to receive IBI3042 or matching placebo.
