Brief Summary

Dolutegravir (DTG) is an HIV-1 integrase inhibitor approved in the United States, Canada, Australia and EU. A dispersible tablet has been developed for pediatric use as an alternative to the granule formulation, already in development, and the approved film-coated tablet. This is a single-center, randomized, open-label, 5-way crossover study in healthy adult subjects. The study will evaluate the relative bioavailability of five dosing regimens: 20 mg DTG pediatric granules (Treatment A) and of DTG 20 mg dispersible tablets (DTG 20 mg DT) after dispersed in: low mineral content(LMC) water (Treatment B); dispersed in CONTREX™ mineral water (Treatment C); dispersed in low mineral content water and consumed after standing for 30 minutes (Treatment D) and dispersed in CONTREX mineral water and consumed after standing for 30 minutes (Treatment E). Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 7-14 days after the last dose of study drug. CONTREX is a trademark of Nestlé Waters Corporation.

• The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
• Lactating females.
• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• Regular use of tobacco- or nicotine-containing products within 60 days prior to screening.
• Unable to refrain from the use of prescription or non-prescription drugs, including vitamins, 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 medication, unless in the opinion of the investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
• The subject's systolic blood pressure is outside the range of 90-140 millimeters of mercury (mmHg), or diastolic pressure is outside the range of 45-90 mmHg, or heart rate is outside the range of 50-100 beats per minute (bpm) for female subjects or 45-110 bpm for male subjects.
