Trial overview
Official title: A single-centre, randomized, double-blind (sponsor unblinded), placebo-controlled two-part study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of GSK2982772, in single (in both fed and fasted states) and repeat oral doses in healthy male subjects
Trial description: This study is the first administration of GSK2982772 in humans. The study will evaluate the safety, tolerability, pharmacokinetics (PK), and exploratory pharmacodynamics (PD) of single and repeat oral doses of up to 14 days with GSK2982772 in healthy male subjects. This study is planned to include approximately 52 subjects and will consist of 2 parts: Part A – single ascending dose, randomized, placebo controlled, 4 way crossover. In addition to the crossover treatment periods, up to 8 subjects in cohort 2 will participate in an additional treatment period and receive GSK2982772 with a high-fat meal. Part B – repeat dose, randomized, placebo controlled, sequential-group. In both cohorts of Part A (Cohorts 1 and 2), subjects will be randomized equally (1:1:1:1) to one of 4 treatment sequences. Within each period, allocation of active to placebo treatment will be 3:1. In all cohorts in Part B (Cohorts 3, 4 and 5) subjects will be randomized to GSK2982772 or placebo in a 3:1 ratio. If required, subjects in the additional cohorts in Part A (Cohort 6) and Part B (Cohort 7) will be randomized to GSK2982772 or placebo in a 1:1:1:1 and 3:1 ratio, respectively. The study duration, including screening and follow-up, is not expected to exceed 105 days for any subject in the study.

Accepts healthy volunteers
Yes
- Male subjects between 18 and 65 years of age inclusive, at the time of signing the informed consent.
- Healthy as determined by the Investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, neurological examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the Investigator in consultation with the Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Note: Screened subjects with laboratory values outside of the normal range may be repeated once for inclusion into the study at the discretion of the Investigator.
- Alanine aminotransferase (ALT) and bilirubin >1.5x Upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
