Arms Assigned Interventions
Experimental: COHORT 1
Interlocking design with Cohort 2. Single dose; treatment period over 2 days such that two subjects will receive GSK1325756 and at least one subject will receive placebo on Day 1. The remaining subjects will be dosed on day 2 of each treatment period assuming adequate safety from Day 1. Placebo and an escalation of GSK1325756 from 10mg, to 50mg, and 200mg, will be administered over the 6 week long treatment period allowing adequate washout period between doses.
Drug: GSK1325756
Drug will be orally administered in varying amounts over varying time periods as detailed in the 'arms' section.
Other: Placebo
Placebo will be orally administered to at least 4 subjects in each treatment period of each cohort. In each sequence in each cohort, all subjects will receive one dose of placebo.

Experimental: COHORT 3
Placebo controlled, 14-day, once daily, repeat-dose evaluation with one selected dose of GSK1325756 in 14 subjects. Dose selection based on review of safety and tolerability data from cohorts 1 and 2.
Drug: GSK1325756

Detailed Description:

This study will evaluate the safety, tolerability, pharmacokinetics(PK) and pharmacodynamics (PD) of single and repeat oral doses of GSK1325756 in healthy, male volunteer subjects, including the assessment of the effect of GSK1325756 on ex vivo 'C-X-C Motif Ligand 1' (CXCL1)-induced 'Cluster of Differentiation 11b' (CD11b) cell surface expression on peripheral blood neutrophils. Selective antagonism of the interaction between 'C-X-C Receptor Type 2' (CXCR2) and its various chemokine ligands provides a potential strategy for reducing the underlying inflammation that contributes to the progression of Chronic Obstructive Pulmonary Disease (COPD). This study is the first administration of GSK1325756 to humans and will be conducted in four cohorts.

Cohorts 1 and 2 will comprise of a double-blind, placebo-controlled, single dose escalation of GSK132576 in healthy adult males in two interlocking cohorts.

The data generated from this single dose escalation component of the study (safety, tolerability, and where applicable, PK profile, and, if available, PD data) will enable decisions regarding progression from one to dose the next higher dose later within Cohorts 1 and 2. This data will also be reviewed in decisions regarding study progression to repeat dosing in Cohorts 3 and 4, and the most suitable doses of GSK1325756 that should be selected for these repeat dose cohorts.

To prevent pregnancy in a female partner or to prevent exposure of any partner to the investigational product from a male subject's semen, male subjects must use one of the following contraceptive methods:

  • Abstinence, defined as sexual inactivity consistent with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • Significant cardiac, pulmonary, metabolic, renal, gastrointestinal or other conditions that in the opinion of the investigator and/or GSK medical monitor, places the subject at an unacceptable risk as participant in this trial

  • A positive test for HIV antibody.
  • History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males. One unit is equivalent to 8 grams of alcohol: a half-pint (~240 milliLitres(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: 3 months, 5 half-lives or twice the duration of the expected biological effect of the investigational product (whichever is longer).
  • Exposure to more than four new chemical entities within 12 months prior to the first 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. Prescription and non-prescription non-steroidal anti-inflammatory drugs are not permitted.
  • 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.

  • Subject is mentally or legally incapacitated.
  • Consumption of red wine, seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.
