Abstract: To evaluate the safety, tolerability, pharmacokinetics and acceptability of the injectable agent, GSK1265744 long-acting injectable (744LA), in healthy, HIV-uninfected men and women. It is a multi-site, double-blind, two-arm, randomized, placebo-controlled trial of the safety, tolerability, and acceptability of 744LA. HPTN-077 will study HIV-uninfected men and women at low to minimal risk for acquiring HIV infection, ages 18 to 65. of approximately 176 men and women, randomized 3:1, with 132 in the active drug arm, and 44 in the placebo arm. It is anticipated that approximately 60% of the enrolled participants will be women. Participants will be randomized to receive daily oral GSK1265744 (30 mg tablets) or daily oral placebo for 4 weeks, followed by a one-week washout, to assess safety and tolerability before they receive injections. After safety and tolerability assessments from the oral phase have been completed (if no concerns are identified), participants will enter the injection phase of the study and will receive two intra-muscular (IM) gluteal injections of 744LA (800 mg, administered as two 400 mg injections) or placebo (matching vehicle control) at three study visits performed at 12-week intervals.
