A Study to Evaluate the Safety, Tolerability and Blood Levels of GSK3915393 Administered to Healthy Participants of Chinese, Japanese and European Ancestry and to Assess Effects of GSK3915393 on Nintedanib

Phase 1
Completed
Conditions
Idiopathic Pulmonary Fibrosis
Interventions
Registration Number
NCT06625489
Lead Sponsor
GlaxoSmithKline
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.

Exclusion Criteria

History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention or interfering with the interpretation of data Participants with systolic blood pressure (BP) greater than (>) 140 millimeter of mercury (mmHg) or diastolic BP > 90 mmHg at screening or pulse rate outside the range of 40 to 100 beats per minute (bpm) will be excluded from the study Alanine transaminase (ALT) or aspartate aminotransferase (AST) >1× upper limit of normal (ULN) Total bilirubin >1.5×ULN; Participants with Gilbert's syndrome can be included with total bilirubin >1.5×ULN as long as direct bilirubin is less than or equal to (≤) 1.5×ULN Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones) QT interval corrected (QTc) >450 milliseconds (msec) at Screening visit based on the average of triplicate ECGs Unable to refrain from the use of prescription or non-prescription drugs, including vitamins, probiotics, antacids, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study intervention, unless in the opinion of the Investigator and the Medical Monitor, the medication will not interfere with the study procedures or compromise participant safety
