Effects of BI 201335 NA on Cytochrome P450 and P-glycoprotein Activity Using a Probe Drug Cocktail in Healthy Volunteers

NCT ID: NCT02182336

Last Updated: 2014-07-18

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 23 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-06-30

Brief Summary

The objective of this trial was to quantify the effect of oral single-dose (480 mg) and steady-state BI 201335 NA (240 mg BID) on intestinal and hepatic cytochrome P450 (CYP) and P-glycoprotein (P-gp) probe drugs as a means of predicting drug interactions. The AUCs for the probe drugs caffeine, warfarin, omeprazole, dextromethorphan, midazolam, and digoxin were assessed.

• Concomitant drugs, nutraceuticals, and herbal remedies that in the opinion of the investigator (in consultation with the BI medical monitor or pharmacokineticist), would interfere with either the absorption, distribution or metabolism of BI 201335 NA, or other study drugs
• Use of drugs, which might reasonably influence the results of the trial or that prolong the QT/QTc interval within 30 days prior to screening until trial completion
