Brief summary: The current study is designed to assess the safety, tolerability, pharmacokinetics (PK), gastrointestinal (GI) transit time and pharmacodynamic (PD) biomarkers of repeat oral doses of GSK3179106 administered for 14 days in normal healthy subjects. It is a randomized, double-blind, placebo-controlled, ascending cohort study. A total of 48 subjects will be randomized (8 subjects/cohort) with 3:1 allocation to GSK3179106 or matching placebo.


Eligibility criteria: Inclusion Criteria:

* Capable of giving signed informed consent which includes compliance with the requirements and restrictions

Exclusion Criteria:

* ALT and bilirubin \>1.5xupper limit of normal (ULN) (isolated bilirubin \>1. ULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%).
