Linerixibat and Obeticholic Acid Drug Interaction Study in Healthy Subjects

Phase 1

Completed

Conditions: Cholestasis

Interventions: Drug: GSK2330672 (linerixibat)
Drug: Obeticholic acid

Registration Number: NCT04053023

Lead Sponsor: GlaxoSmithKline

Brief Summary: In participants with inadequate response/intolerance to ursodeoxycholic acid (UDCA) taking obeticholic acid (OCA) who experience pruritus (due to primary biliary cholangitis \[PBC\], OCA, or both) the addition of linerixibat to OCA therapy may be considered following marketing approval. It is therefore important to characterize any potential effect of linerixibat on the pharmacokinetics of OCA in humans at clinically relevant dosages. Accordingly, a drug-drug interaction (DDI) study with linerixibat (potential perpetrator) and OCA (potential victim) will be conducted to inform both future clinical trials with linerixibat and the potential concomitant administration of these drugs in a clinical setting. This is a single-center, one part (with optional second part) open-label, single sequence crossover, drug interaction study to investigate the effect of linerixibat on plasma concentrations of OCA and OCA conjugates in healthy participants. Approximately 19 participants will be enrolled in part A and further 19 participants in part B (if performed) in the study and will have a phone call follow-up till 7-14 days post-last linerixibat dose.

Inclusion Criteria

Between 18 and 80 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, vital signs, laboratory tests, and ECG. A participant with a clinical abnormality or laboratory parameter (i.e., outside the reference range for the population being studied), which is not specifically listed in the eligibility criteria, may be included only if the investigator agrees in consultation with the GlaxoSmithKline (GSK) medical monitor and documents in the source documentation that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures or outcomes.
