Antag Therapeutics, a leading biopharmaceutical company focused on targeting the Glucose-Dependent Insulinotropic Polypeptide (GIP) receptor to pioneer novel treatments for obesity, today announced that the U.S. Food and Drug Administration (FDA) has accepted its Investigational New Drug (IND) application for its lead molecule, AT-7687. This milestone enables Antag Therapeutics to initiate its Phase I clinical trial, which will evaluate the safety, tolerability, and pharmacokinetics of AT-7687 in both healthy lean and healthy obese subjects. The study will also explore AT-7687 as a monotherapy and in combination with semaglutide, a GLP-1 receptor agonist, in healthy obese individuals.
AT-7687 is a peptide GIP receptor antagonist designed for once-weekly subcutaneous administration. Highly translational preclinical studies have shown that AT-7687 attenuates weight gain and enhances GLP-1-mediated weight loss while improving lipid profiles, particularly LDL, independent of weight change. Importantly, these benefits are not associated with gastrointestinal side effects. The upcoming Phase I trial will assess safety, tolerability, and pharmacokinetics of AT-7687 alone and in combination with semaglutide in healthy lean and healthy obese subjects.
