Study Summary

Dolutegravir (DTG, GSK1349572 is an integrase inhibitor that is currently in Phase 3 clinical development for the treatment of human immunodeficiency virus (HIV) infection. DTG is primarily metabolized by UDP-glucuronosyltransferase (UGT1A1) with cytochrome P450 (CYP)3A4 pathway as a minor route. Corticosteroids have demonstrated induction effects on UGTs and CYP3A4. Corticosteroids are often used in HIV-infected subjects and have the potential to reduce DTG exposure due to enzyme induction when co-administered. The primary objective of this study is to determine whether concomitant prednisone administration can affect the pharmacokinetics (PK) of DTG. The study is a two part, two period, open label study. Part 1 will evaluate the effect of a high prednisone dose on DTG PK with the potential for an additional Part 2 depending on the results from Part 1. In Part 1, approximately 12 healthy subjects will receive DTG 50mg q24h for 5 days in Period 1. Subjects will then be administered DTG 50mg q24h in combination with prednisone 60mg for 5 days followed by a 5 day taper (total duration of 10 days) in Period 2. PK data of DTG will be obtained from Part 1 and used to inform decision making on the need for Part 2. If DTG exposure is reduced by more than 50% in Part 1, Part 2 will be carried out where a second cohort of subjects will receive DTG 50mg q24h DTG for 5 days in Period 1 followed by DTG 50mg q24h in combination with prednisone 20mg for 5 days followed by a 5 day taper (total duration of 10 days) in Period 2. Safety evaluations and serial PK samples for DTG will be collected during each treatment period. A follow-up visit will occur 7-14 days after the last dose of study drug. All doses of study drugs will be taken following a moderate fat meal. This study will be conducted at one center in the United States, with healthy adult male and female subjects.

Primary Outcome

Samples will be collected at predose and 1, 2, 3, 4, 8, 12 and 24 hours post dose
