Interventional
Description of intervention(s) / exposure
Treatment: Drugs - GSK3179106
Treatment: Drugs - Placebo

Experimental: Cohort 1 - Subjects will receive 1 placebo and 3 escalating doses in one of the four treatment periods. The planned dose range is 10 mg to 200 mg. A review of safety and tolerability will occur prior to administration of the next dose level and the same procedure will be followed for each escalating dosing period. The actual doses to be administered may be adjusted based on safety, tolerability, and pharmacokinetic data at previous dose levels; these dose adjustments may involve either an increase or a decrease in the planned dose for both Cohorts 1 and 2

Experimental: Cohort 2 - Cohort 2 will proceed after completion of the treatment periods in Cohort 1. Subjects assigned to Cohort 2 will participate in up to 4 dosing periods which include up to 2 escalating doses and placebo in Periods 1 and 2, and a pilot food effect in Periods 3 and 4. A review of safety and tolerability will occur prior to administration of the next dose level and the same procedure will be followed for each escalating dosing period. The actual doses to be administered may be adjusted based on safety, tolerability, and pharmacokinetic data at previous dose levels; these dose adjustments may involve either an increase or a decrease in the planned dose for both Cohorts 1 and 2


Treatment: Drugs: GSK3179106
GSK3179106 will be provided as white to slightly colored round or oblong tablet for oral administration with unit dose strength of 5 mg, 25 mg and 100 mg

Treatment: Drugs: Placebo
Placebo will be provided as white to slightly colored round or oblong tablet for oral administration with unit dose strength to match actives across all strengths

Eligibility
Key inclusion criteria
* Between 18 and 55 years of age inclusive, at the time of signing the informed consent.
* Healthy as determined by the investigator based on a medical evaluation including medical history, physical 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.
* History of regular bowel habits.
* Male or Female Males: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until at least five half-lives of study medication after the last dose of study medication.

1. Vasectomy with documentation of azoospermia.
2. Male condom plus partner use of one of the contraceptive options below:

Contraceptive subdermal implant, Intrauterine device or intrauterine system, Oral Contraceptive, either combined or progestogen alone Injectable progestogen, Contraceptive vaginal ring.

This is an all-inclusive list of those methods that meet the following GlaxoSmithKline (GSK) definition of highly effective: having a failure rate of less than 1 percentage (%) per year when used consistently and correctly and, when applicable, in accordance with the product label. For non-product methods (e.g., male sterility), the investigator determines what is consistent and correct use.

The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.

Females: A female subject is eligible to participate if she is of non-reproductive potential defined as: Pre-menopausal females with one of the following:

Documented tubal ligation Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion Hysterectomy Documented Bilateral Oophorectomy Postmenopausal defined as 12 months of spontaneous amenorrhea in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause (refer to laboratory reference ranges for confirmatory levels). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.

* Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in this protocol.
Minimum age
18 Years
Maximum age
55 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
* Alanine Transferase (ALT) and bilirubin >1.5x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
* Previous diagnosis of IBS.
* Estimated Glomerular Filtration Rate <60 milliliters per minute 1.73 square meter (mL/min/1.73m^2).
* Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
* History of gastroesophageal reflux disease (GERD), dyspepsia, gastrointestinal (GI) bleeding, GI surgery that could affect motility
* A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.
* A positive pre-study drug/alcohol screen.
* A positive test for human immunodeficiency virus (HIV) antibody.
* History of regular alcohol consumption within 6 months of the study defined as: an average weekly intake of >14 standard drinks. One standard drink is equivalent to 10 grams (g) of alcohol: 285 ml of beer, 100 ml of wine or 30 ml of 40% alcohol by volume distilled spirits.
* Current smoker or use of nicotine containing products within the past 3 months or unable to abstain from smoking tobacco or the use of nicotine-containing products while on study.
* Unable to refrain from consumption of red wine, seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 1 day prior to the first dose of study drug on Day 1 of each dosing period, until completion of the last PK blood sample time point for that dose period.
* Corrected QT interval to Fridericia's formula (QTcF) >450 milliseconds (msec)
* 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.
* 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 for each dosing period until Day 4 of each dosing period, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety. Paracetamol (<=2 grams per day) is acceptable.
* 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).
* Exposure to more than 4 investigational medicinal products within 12 months prior to the first dosing day
* Unwillingness or inability to follow the procedures outlined in the protocol.
* Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
