Drug-drug Interaction (DDI) With a P-gp Inhibitor, Organic Anion Transporting Polypeptide OATP-inhibitor, Food Effect

Effect of P-gp Inhibition, OATP-inhibition and Food on the Kinetics of a Single Oral Dose BI 685509 in Healthy Male Subjects

The primary objective of this trial is to investigate the relative bioavailability of BI 685509 given alone under fasted conditions (Reference, R) compared to the intake after a high fat, high caloric breakfast (Test 1, T1), to combined administration with itraconazole under fasted conditions (Test 2, T2) and to combined administration with rifampin under fasted conditions (Test 3, T3).

The secondary objective is the evaluation and comparison of several pharmacokinetic parameters between the treatments.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: BI 685509 Fasted Conditions; Drug: BI 685509 After Standardised Breakfast; Drug: Itraconazole; Drug: Rifampin

Detailed Description

BI 685509 is a substrate of the drug transporters P-gp and Organic anion transporting polypeptide 1B1 and 1B3 (OATP1B1/OATP1B3). Inhibition of these transport proteins may result in an increased drug exposure which might impact the safety of the patients. Therefore this trial should investigate whether and to what extent the inhibition of P-gp (mediated by itraconazole) and the inhibition of OATP1B1/OATP1B3 (mediated by rifampin) affects kinetics of BI 685509. Itraconazole and rifampin are recommended probe drugs to test in-vivo inhibition of P-gp and OATP1B1/OATP1B3.

Furthermore the food effect will be investigated in this study.
