Phase I Study of GSK2982772 in Japanese Healthy Male Participants

The study plans to enroll approximately 12 subjects. The main objective of the study is to assess the safety, tolerability and pharmacokinetics (PK) of the three times a day (TID), dosing of GSK2982772, in Japanese healthy male subjects. The study will comprise of four study periods each at least 7 days in duration with subjects in-house for 4 nights (through 72 hrs after the first dose). During each treatment period (TP), subjects will be admitted to the unit the day before dosing and will be discharged after completion of the 72 hours post-dose assessments. There will be a washout of atleast 7-days between the TP doses for each individual, post which there will be 7-days follow-up. The dose range proposed in this study is based on a low starting dose, which will be escalated to the highest dose that is intended for the Phase 2b dose range study. The decision to proceed to the next dose-level, of GSK2982772 within the study will be made by principal investigator and GSK Medical Monitor per each dosing periods. The study duration is approximately 22 weeks.
