Trial overview

Official title: A Two Part, Phase I, Randomized, Placebo Controlled, Double Blind Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single and Repeat Escalating Doses of GSK1325756 Solution for Infusion, and Absolute Bioavailability Relative of an Oral Dose, in Healthy Adult Subjects Protocol 201022
Trial description: This will be the first time GSK1325756 Solution for Infusion formulation that has been administered to humans. Prior studies have been performed with oral GSK1325756. The primary objectives of this study are to obtain information on the safety, tolerability, and pharmacokinetics (PK) of single and twice daily intravenous (IV) administration of GSK1325756 in healthy subjects. In Part A, single, escalating doses will be given in the same cohort of subjects after a seven day washout. In addition, the study will evaluate the absolute bioavailability of a single dose of the current oral tablet formulation as compared to the IV formulation in Part A. In Part B, twice daily (BID) intravenous dose administration will be given for 5 days (9 total doses) in two separate cohorts of subjects. Data from this study will provide understanding of the safety, tolerability, and PK of intravenously administered GSK1325756 twice daily to guide dose selection in future clinical studies in patients with viral respiratory tract infections

Primary outcomes:

Number of subjects with adverse events (AEs)

Timeframe: Part A and Part B: from Day -1 until 7 to 10 days post-last dose

Changes over time in clinical laboratory evaluations from pre-dose values

Timeframe: Part A and Part B: from Day -1 until 7 to 10 days post-last dose

Changes over time in vital signs from pre-dose values

Timeframe: Part A and Part B: from Day -1 until 7 to 10 days post-last dose

Changes over time in electrocardiogram (ECG) parameters from pre-dose values

Timeframe: Part A and Part B: from Day -1 until 7 to 10 days post-last dose

GSK1325756 PK parameters following single dose administration in Part A and on Day 1 of Part B

Timeframe: Part A: Pre-dose, 0.5 hour (hr), 1hr (end of infusion/post oral dose), 1.5, 2, 3, 4, 8, 12, 24hrs post-dose in each treatment period.

GSK1325756 PK parameters following repeat dose administration (Part B, Day 5)

Timeframe: Part B: Day 5 at pre-dose, 0.5, 1hr (end of infusion), 1.5, 2, 3, 4, 8, 12 and 24 hrs post-dose

Secondary outcomes:

GSK1325756 PK parameters following single and repeat IV dose administration to assess dose proportionality

Timeframe: Part A: Pre-dose, 0.5hr, 1hr (end of infusion/post oral dose), 1.5, 2, 3, 4, 8, 12, 24hrs post-dose. Part B: Day 1 and Day 5: pre-dose, 0.5, 1hr (end of infusion), 1.5, 2, 3, 4, 8, 12 and (Day 5 only) 24 hrs post-dose. Day 2-4: pre-dose (each dose)

GSK1325756 PK parameters following single IV and oral dose administration of a given dose of GSK1325756 (Part A) to determine the absolute bioavailability

Timeframe: Part A: Pre-dose, 0.5hr, 1hr (end of infusion/post oral dose), 1.5, 2, 3, 4, 8, 12, 24hrs post-dose

GSK1325756 accumulation ratio

Timeframe: Part A: Pre-dose, 0.5hr, 1hr (end of infusion/post oral dose), 1.5, 2, 3, 4, 8, 12, 24hrs post-dose Part B: Day 1 and Day 5: pre-dose, 0.5, 1hr (end of infusion), 1.5, 2, 3, 4, 8, 12 and (Day 5 only) 24 hrs post-dose. Day 2-4: pre-dose (each dose)

GSK1325756 time invariance

Timeframe: Part A: Pre-dose, 0.5hr, 1hr (end of infusion/post oral dose), 1.5, 2, 3, 4, 8, 12, 24hrs post-dose Part B: Day 1 and Day 5: pre-dose, 0.5, 1hr (end of infusion), 1.5, 2, 3, 4, 8, 12 and (Day 5 only) 24 hrs post-dose. Day 2-4: pre-dose (each dose)

GSK1325756 Pre-dose concentrations (C12/Ctau) on Day 2 through 4

Timeframe: Part B: Day 2 to Day 4 (pre-dose; each dose)

Correlation between PK parameters and various safety parameters, if appropriate

Timeframe: Part A and Part B: from Day -1 until 7 to 10 days post-last dose
