Study of IPG1094 Tablets in Chinese Healthy Adults and Obese Adults

9. November 2026 aktualisiert von: Nanjing Immunophage Biotech Co., Ltd

A Phase Ⅰ Clinical Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Preliminary Weight-Loss Effect of IPG1094 Tablets in Chinese Healthy Adults and Obese Adult Participants

This is a Phase I clinical study to evaluate the safety, tolerability, pharmacokinetics and preliminary weight-loss effect of IPG1094 tablets. The study includes three parts: Part A is single ascending dose in healthy volunteers; Part B is multiple ascending dose in healthy volunteers; Part C is multiple-dose exploration in obese adult participants. Subjects will be randomly assigned to receive IPG1094 or matching placebo. Safety, blood drug concentration and weight-related indicators will be followed up.
