An Study to Investigate the Recovery, Excretion, and Pharmacokinetics of 14C-GSK1265744 Administered as a Single Oral Dose and a Study to Describe the Pharmacokinetics of a Supratherapeutic Dose of GSK1265744 in Healthy Adult Subjects
October 31, 2013 updated by: ViiV Healthcare
An Open Label, Non-Randomized, Mass Balance Study to Investigate the Recovery, Excretion, and Pharmacokinetics of 14C-GSK1265744 Administered as a Single Oral Dose and a Placebo-Controlled, Randomized Study to Describe the Pharmacokinetics of a Supratherapeutic Dose of GSK1265744 in Healthy Adult Subjects
This will be a two-part study in healthy adults.
Part A is a phase 1, non-randomized, open label, single-dose, single-centre mass balance study utilizing a radiolabeled dose to investigate the recovery, excretion, and pharmacokinetics of oral GSK1265744 in a cohort of 6 healthy adult male subjects.
Subjects will undergo a pre-study screening visit within 30 days of the first dose and those who successfully pass pre-study assessments and meet eligibility criteria will be enrolled into the study to receive the equivalent of a 30 mg dose of GSK1265744 as an oral solution, containing approximately 70 microcuries (mcg Ci) [0.96 millisieverts (mSv)] of radioactivity under fasted conditions.
Blood, urine and fecal samples will be collected for a maximum of 504 hours (21 days) following study drug administration.
In Part B, approximately 10 healthy male and female subjects will be enrolled to evaluate the single-dose safety, tolerability and PK of supratherapeutic dose of GSK1265744 150 mg compared with placebo.
Each subject will receive a single dose of GSK1265744 150 mg or placebo on Day 1 under fasting conditions in the morning.
Blood, urine and fecal samples will be collected for 336 hours (14 days) following dosing.
