Purpose

This study is a Phase IIa, randomized, multi-site, two-arm, double-blinded study to evaluate the safety, tolerability, and acceptability of GSK1265744 long acting injectable formulation (744 LA) in adult male subjects. To evaluate the safety and tolerability of the injectable agent, 744 LA (800 milligrams (mg) dose administered at three time points at 12 week intervals) through Week 41 in HIV-uninfected men. Eligible participants will be randomized in a 5:1 ratio to receive 744 LA or matching placebo. Participants will receive daily oral 744 (30 mg tablets) or matching placebo for 4 weeks during the Oral Phase of the study, followed by a one week washout period. Following safety lab assessments from the Oral Phase, participants will enter the Injection Phase and receive Intramuscular (IM) injections of 744 LA or placebo at three time points at 12 week intervals. IM injections will consist of 800 mg of 744 or a matching control

Primary Outcome Measures

  • Number of Participants With Any Grade 2 or Higher Event in the Injection Phase [ Time Frame: Up to Week 41 ]
    Clinical adverse event (AE) were graded using the Division of Acquired Immunodeficiency Syndrome (DAIDS) table for grading the severity of adult and pediatric AE Version 1.0, December 2004; Clarification August 2009. The grades were: 1 (mild)=Symptoms causing no or minimal interference with usual social and functional activities; 2 (moderate)= Symptoms causing greater than minimal interference with usual social and functional activities; 3 (severe)= Symptoms causing inability to perform usual social and functional activities; 4 (potentially life threatening): Symptoms causing inability to perform basic self-care functions or medical or operative intervention indicated to prevent permanent impairment, persistent disability, or death. Data has been presented for any Grade 2 or higher event in the injection phase for injection phase (Week 5- Week 41).
  • Number of Participants Who Recieved Injection Site Reaction (ISR) Related Concomitant Medication in the Injection Phase [ Time Frame: Up to Week 41 ]
    The concurrent medications that were consumed by participants during the injection phase were of the class nervous system, musculo-skeletal system, genito urinary systems and sex hormones, various, respiratory system, dermatologicals, alimentary tract and metabolism, sensory organs, systemic hormonal preparations, excluding sex hormones, blood and blood forming organs, cardiovascular system. The participants who took medication from any of the above class of during the injection phase (Week 5-Week 41) have been presented.
  • Number of Participants Who Experienced Grade 2 or Higher Laboratory Results in the Injection Phase [ Time Frame: Up to Week 41 ]
    The severity of laboratory results was graded according to the DAIDS table for grading the severity of adult and pediatric AE Version 1.0, December 2004; Clarification August 2009. The DAIDS displays events as Grades 1-5 based on this general guideline: Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening. Data for Number of participants who experienced grade 2 or higher laboratory results in the injection phase (Week 5-Week 14) have been presented.
  • Number of Participants Who Had Abnormal Electrocardiogram (ECG) Findings in the Injection Phase [ Time Frame: Up to Week 41 ]
    Full 12-lead ECGs included heart rate, PR, QRS, QT and QTc intervals. Measurements were taken from the participant following 5 minutes of rest in a semi-supine position. ECGs were performed at Week 5, Week 17, Week 29 and Week 41 in the injection phase (Week 5-Week 41). ECG abnormalities characterized as abnormal-not clinically significant (A-NCS) and abnormal-clinically significant (A-CS) upto Week 41 have been presented. There were no A-CS findings for ECG in the injection phase.
  • Change From Baseline in Vital Sign Assessment for Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) in the Injection Phase [ Time Frame: Baseline (Week 5) to Week 41 ]
    Vital signs measurements were performed for SBP and DBP following 5 minutes of rest. Baseline was defined as the first injection at Week 5 for the injection phase. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline value at Week 17, Week 29 and Week 41.
  • Change From Baseline in Vital Sign Assessment for Heart Rate (HR) in the Injection Phase [ Time Frame: Baseline (Week 5) to Week 41 ]
    Vital signs measurements were performed for HR following 5 minutes of rest. Baseline was defined as the first injection at Week 5 for the injection phase.

The sample collected 12 Week following each injection served as the pre-dose sample for the subsequent dosing interval. Two additional samples were collected 4 and 8 Week after the first injection (Week 9 and Week 13), and 1 additional sample was collected 6 Week following the second and third injections (Week 23 and Week 35). Assessment was carried out for Ctau defined as the concentration at the end of the dosing interval and Cmax defined as the maximum observed plasma concentration.

The sample collected 12 Week following each injection served as the pre-dose sample for the subsequent dosing interval. Two additional samples were collected 4 and 8 Week after the first injection (Week 9 and Week 13), and 1 additional sample was collected 6 Week following the second and third injections (Week 23 and Week 35). Assessment was carried out for tmax defined as the time to the maximum observed plasma concentration and t½ defined as the time taken for the concentration of drug in the blood to decrease by half of the original amount.
