Detailed Description:

This study will evaluate GSK1265744, which is an investigational, injectable HIV medicine. The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of GSK1265744 in healthy, HIV-uninfected adults. Study researchers will evaluate the use of GSK1265744 for both the prevention of HIV infection (known as pre-exposure prophylaxis [PrEP]) and for the treatment for HIV infection.

Participants will be randomly assigned to one of two groups: Group 1 will receive GSK1265744 tablets (also called oral 744) and injections (also called GSK1265744 long acting or 744LA), and Group 2 will receive placebo tablets and injections. Study visits will occur at study entry and Weeks 2, 4, 5, 6, 9, 13, 17, 18, 23, 29, 30, 35, 41, 53, 65, 77, and 81. From study entry through Week 4, participants will take a GSK1265744 tablet (Group 1) or a placebo tablet (Group 2) once a day. For 1 week after participants stop taking their assigned tablets, study researchers will assess safety and tolerability. If no safety or tolerability concerns are identified, participants will receive two injections of GSK1265744 (Group 1) or placebo (Group 2) at Weeks 5, 17, and 29.

All study visits will include HIV counseling, a physical examination, a medical history review, and a blood collection. Select study visits will include adherence counseling, behavioral and acceptability assessments, a urine collection, an electrocardiogram (ECG), and rectal and/or vaginal swabs.
