Brief Summary

This study aims to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of single, oral ascending doses, and repeat oral doses of GSK1325756 administered to healthy adult male volunteers. This study is the First Time in Human study for 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.

Study Groups

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.

Group Type: EXPERIMENTAL

GSK1325756

Intervention Type: DRUG

Drug will be orally administered in varying amounts over varying time periods as detailed in the 'arms' section.

Placebo

Intervention Type: OTHER

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.

COHORT 2

Interlocking design with Cohort 1. 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 25mg, to 100mg, and 400mg, will be administered over the 6 week long treatment period allowing adequate washout period between doses.

Group Type: EXPERIMENTAL

GSK1325756

Intervention Type: DRUG

Drug will be orally administered in varying amounts over varying time periods as detailed in the 'arms' section.

Placebo

Intervention Type: OTHER

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.

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.

Group Type: EXPERIMENTAL

COHORT 4

Placebo controlled, 14-day, once daily, repeat-dose evaluation with a higher selected dose of GSK1325756 in 14 subjects. Dose selection based on review of safety and tolerability data from cohort 3.

Eligibility Criteria

Inclusion Criteria

• Aspartate Transaminase (AST), Alanine Transaminase (ALT), alkaline phosphatase and bilirubin ≤ 1.5x Upper Limit of Normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and Electrocardiogram (ECG). A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
• Males between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• Subjects must agree to use one of the contraception methods listed below:

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.
• Condom (during non-vaginal intercourse with any partner - male or female) OR
• Condom and occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository) (during sexual intercourse with a female) This criterion must be followed from the time of the first dose of study medication until at least 3-months post-last dose of study drug.
