Pharmacokinetics, Safety, and Tolerability of GS-1427, an Oral Prodrug of a Potent and Selective α4β7 Integrin Inhibitor, in Healthy Participants. (PubMed, J Clin Pharmacol) - "The bioavailability of tablet versus capsule formulations and the effect of food and an acid-reducing agent (omeprazole) on exposure were also assessed. All AEs were grade 1 in severity and no serious AEs or deaths were reported. The pharmacokinetics, safety, and tolerability results from this study support further evaluation of GS-1427 in a phase 2 trial in patients with UC."

Discovery of GS-1427: A potent and selective, oral α4β7 inhibitor for the treatment of inflammatory bowel disease (ACS-Fall 2025) - "This pathway has been clinically validated for the treatment of inflammatory bowel disease (IBD) with the approval of vedolizumab, a monoclonal antibody that targets α4β7 disrupting its binding to MadCAM-1. GS-1427 demonstrates in vivo activity comparable to an antibody control in a preclinical model of T cell gut trafficking, and is efficacious in a murine IBD disease model. This presentation will describe the discovery, preclinical evaluation, and early clinical data for GS-1427, which is currently in Phase 2 clinical trials for ulcerative colitis."
