Relative Bioavailability Study in Healthy Subjects

Completed · Phase 1

Conditions studied: Infections, Bacterial

In brief

Part 1 of this study will assess the relative bioavailability of GSK1322322 administered as one of three investigational tablets compared to powder in a bottle formulation. Pharmacokinetics of these three tablets will be evaluated and the investigation tablet with the optimal PK profile will be progressed to Part 2. In Part 2 the investigational tablet selected from Part 1 will be coadministered with food alone, an H2 blocker alone, or an H2 blocker given in combination with ascorbic acid to evaluate the effect on GSK1322322 pharmacokinetics. Plasma GSK1322322 PK profile, safety, and tolerability will be assessed from each dose group.

You may not qualify if…

• The subject has a positive pre-study drug/alcohol screen.
• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).

• History of regular alcohol consumption within 6 months of the study defined in the protocol.
• The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
• Exposure to more than four new chemical entities within 12 months prior to the dosing day.
• Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
