* Initiation or increase in dose of bezafibrate or fenofibrate at any time during the 3 months prior to screening. Participants may join the study on stable doses of these medications, but no change or discontinuation is permitted until completion of the Main Study Period.
* Initiation or increase in dose of any of the following in the 8 weeks prior to screening: rifampicin, naltrexone, naloxone, nalfurafine, or sertraline. Participants may join the study on stable or decreased doses of these medications, but no change in dose is permitted until completion of the Main Study Period.
* Bile acid binding resin use: a participant must discontinue use of cholestyramine, colesevelam, colestipol or colestimide prior to the start of the Initial Study Period (no later than Day-2). Note: these drugs may be administered after completion of the Main Study Period, if clinically indicated.
* Obeticholic acid use: a participant must discontinue use of obeticholic acid at least 8 weeks prior to the start of the Initial Study Period and may not restart until after the end of the study.

* QT interval corrected for heart rate QTc >480 millisecond (msec).
* History of sensitivity to the study treatment or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GlaxoSmithKline (GSK) Medical Monitor, contraindicates their participation in the study.
* History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males or >14 units for females.

Summary
Brief summary
This study is being conducted to evaluate the efficacy, safety and tolerability of GSK2330672 administration for the treatment of pruritus (itch) in participants with primary biliary cholangitis (PBC). Participants will receive either placebo or one of the 4 dose regimens of GSK2330672 (20 milligram \[mg\], 90 mg or 180 mg taken once daily or 90 mg twice daily). Participants on GSK2330672 will also receive placebo tablets to maintain blinding. The study has a prospectively defined adaptive design that will utilize interim data to further inform and potentially optimize the doses under investigation. Hence, additional dose regimen may be added during study. The total duration of a participant in the study will be up to 45 days of screening and 24 weeks of study including follow-up.
