TMC435-TiDP16-C107: This Study Measures the (Possible) Influence of TMC435 on the Activity of a Selected Set of Drug-degrading Proteins by Measuring the Blood Levels of Drugs That Have Been Taken Together With TMC435 and That Are Known to be Specifically Degraded by These Drug-degrading Proteins.

Summary

The purpose of this study is to determine whether TMC435 influences the activity of certain drug-degrading proteins in the human body. The drug-degrading proteins investigated in this study belong to the Cytochrome P (CYP) family and are called CYP1A2, CYP2C9, CYP2D6, CYP3A4 and CYP2C19. The activity of these drug-degrading enzymes are determined by measuring the blood levels of a selected set of drugs, which are taken together with TMC435, and, which are known to be specifically degraded by a certain member of the CYP family. This selected set of drugs (which are taken together and therefore called a "drug cocktail") are considered as "probes" of these respective drug-degrading enzymes. By measuring the levels of these probes in human blood, the activity of these degrading enzymes are being revealed. In this way, we can determine if TMC435 influences in one way or another the activity of one or several of these selected drug-degrading proteins.
