A Study to Evaluate the Effects of ASA404 Alone or in Combination With Taxane-based Chemotherapies on the Pharmacokinetics of Drugs in Patients With Advanced Solid Tumor Malignancies

Summary

The purpose of this study is to evaluate the potential inhibitory effects of ASA404 on CYP1A2, CYP2C9, CYP3A4 and CYP2C19 mediated metabolism on the respective probe drugs caffeine, diclofenac, simvastatin, and omeprazole, respectively. This will be accomplished by the simultaneous administration of four substrates as part of a cocktail in order to characterize the potential for in-vivo drug-drug interactions. This cocktail approach has been proposed per FDA guidance as a screening tool for potential in-vivo drug-drug interactions Compared to the individual administration of specific probes in multiple studies, simultaneous administration of multiple in-vivo probes of drug-metabolizing enzymes offer several distinct advantages such as minimizing the confounding influence of inter-individual and intra-individual variability over time. Substrates for the CYP enzymes were chosen based on the FDA guidance recommendations taking into account that 1. The substrates are specific for the individual CYP enzymes, 2. There are no interactions among these substrates; and 3. The study will be conducted in a sufficient number of subjects.
