Detailed Description:

This is a study in healthy volunteers to investigate the safety, tolerability, pharmacokinetics (the body's effect on the drug) and pharmacodynamics (the drug's effect on the body) of single and repeat doses of 800 mg GSK2586184. The effect of food and gender on pharmacokinetics will also be investigated following single dosing.

The study is made up of 2 groups of healthy subjects. The first group consists of 6 female subjects who will receive a single dose of 800mg GSK2586184 (study medication) during 2 seperate sessions. One session will involve the female subjects taking the study medication with food and the other session will involve study medication being taken without food. The safety and tolerability of the study medication in female subjects and the effect of food on the pharmacokinetics of the study medication will be investigated.

The second group will consist of 12 healthy male subjects participating in 2 sessions. 8 subjects will receive study medication and 4 will receive placebo (dummy medication) during the course of the study. Neither they or their study doctor will know which one they are given. Each male subject will receive a single dose of study medication or placebo followed by 13 days of twice daily dosing of study medication or placebo. Each dose will be taken with food.The single dose results from this group of subjects will be compared to the female group to investigate the effect of gender on pharmacokinetics. The safety and pharmacokinetics of repeat dosing will be investigated. The effect of repeat dosing on kidney function and the immune system will also be investigated.

The study will take place in the SGS Clinical Pharmacology Unit in Antwerp, Belgium. A pharmaceutical company, GlaxoSmithKline, is funding the study.

  • History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol and the following can be used as a guide: a half-pint (~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits
  • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first 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)
  • The subject is unwilling to abstain from alcohol consumption from 48 hr prior to dosing until discharge from the clinic, and for 24 hr prior to all other out-patient clinic visits
  • Exposure to more than four new chemical entities within 12 months prior to the first dosing day
  • Unable to refrain from the 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 malignancy, except for adequately treated non-invasive cancer of the skin (basal or squamous cell) or cervical carcinoma in situ (>2 yrs prior to dosing)
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period
  • Subjects with a history of or a current thyroid disease or epilepsy
  • Subjects exposed to radiation in the 6 months, (except for X-ray/CT examinations of the extremities) prior to the first GFR assessment (Day -2) (cohort B only)
