Description of intervention(s) / exposure
Digoxin is a substrate of P-gp and influences intestinal absorption, renal tubular secretion and biliary-intestinal secretion. Therefore, drugs that inhibit P-gp have the potential to alter digoxin pharmacokinetics. The primary objective of this study is to determine the effect of multiple once-daily doses of HM30181A on the single-dose PK of digoxin.
Eligible participants will receive a single oral tablet dose of digoxin 0.25mg and will provide blood samples for analysis for 6 days post-dosing (Treatment Period 1). After at least a 10 day washout, Treatment Period 2 will start. Participants will receive daily oral tablet doses of 15mg HM30181A for 3 days. One hour after the third dose (i.e. Day 3) they will receive another single oral tablet dose of digoxin 0.25mg. Blood samples will be collected for days 1-8, and at Day 17. Safety will be monitored regularly with laboratory tests, recording of AEs, ECGs and vital signs. Participants will be resident at the Zenith Clinical Site for dosing (all doses will be under the direct supervision of study site staff) and days when multiple blood samples are required.

Outcomes
Primary outcome [1] 305779 0
The primary objective of the study is to determine the effect of multiple once-daily doses of HM30181A on the single-dose pharmacokinetics of digoxin.
The primary endpoint will be the ratio of the AUC0-8 of digoxin in the plasma after digoxin administration on Day 3 after HM30181A in Treatment Period 2 vs digoxin administration alone in Treatment Period 1.
Timepoint [1] 305779 0
Blood samples for determination of plasma concentrations of digoxin will be collected on:
Treatment Period 1: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 72, 96 and 120 hours, and Day 17 post-dose digoxin.
Treatment Period 2: Days 1, 2 and 3: predose HM30181A. Days 3-8: pre-dose digoxin and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 72, 96 and 120 hours, and Day 17 post-dose Day 3 digoxin

Summary
Brief summary
HM30181 methanesulfonate monohydrate is a novel orally administered P-glycoprotein (P-gp) inhibitor that was discovered and originally developed by Hanmi Pharmaceutical Co., Ltd., Seoul, South Korea. The compound is in clinical development and is orally administered in combination with chemotherapeutic agents (paclitaxel, irinotecan) to enhance the oral bioavailability of these agents.
Digoxin is a substrate of P-gp and influences intestinal absorption, renal tubular secretion and biliary-intestinal secretion. Therefore, drugs that inhibit P-gp have the potential to alter digoxin pharmacokinetics. HM30181A has low systemic bioavailability and is present in plasma at concentrations that are far below those calculated to inhibit systemic or renal P-gp. Thus, it is anticipated that any effect of HM30101A on the bioavailability of digoxin will be due to its effect on the gastrointestinal (GI) P-glycoprotein, and not upon renal clearance.
