Brief Summary

GSK3915393 is a new medicine which is being developed for a chronic lung disease called Idiopathic Pulmonary Fibrosis (IPF). This is a healthy participant study which has two parts. Part A will assess the safety, tolerability, and blood levels of GSK3915393 given as a single dose to healthy participants of Chinese, Japanese, and European ancestries. Part B is a drug-drug interaction (DDI) study that examines the effect of a single dose of GSK3915393 on the blood levels of a single dose of nintedanib, which is an approved drug for IPF.
