Evaluation of Pharmacokinetic Interaction Between GSK3640254 and Caffeine, Metoprolol, Montelukast, Flurbiprofen, Omeprazole, Midazolam, Digoxin, and Pravastatin in Healthy Adults

• Status: Completed
• Trial end date: 2021-03-09

Summary

This is an open-label, single sequence study that is being conducted to investigate the potential drug-drug interaction (DDI) when GSK3640254 is co-administered with a cocktail of cytochrome P450 (CYP) enzymes and transporter probe substrates in healthy participants. This study will aid in understanding these interactions and resulting changes in exposure (if any) when drugs that are metabolized via these pathways are given in combination with GSK3640254. The study will consist of a Screening period and 3 sequential treatment regimens. Participants will be administered a single dose of probe substrate drugs (caffeine 200 milligram (mg), metoprolol 100 mg, montelukast 10 mg, flurbiprofen 100 mg, omeprazole 40 mg, midazolam 5 mg, digoxin 0.25 mg and pravastatin 40 mg) on Day 1, followed by washout of 10 days. Participants will then receive GSK3640254 200 mg once daily on Days 11 to 20 followed by co-administration of probe substrate drugs with GSK3640254 on Day 21. The total duration of the study will be approximately 54 days including Screening. Approximately 20 participants will be treated in the study.
