Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 on the steady-state pharmacokinetics of efavirenz or raltegravir , and vice versa. Steady state is a term which means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Efavirenz and raltegravir are two antiretroviral drugs for treatment of human deficiency virus (HIV) infection. Pharmacokinetics (pk) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

TMC435 is being investigated for treatment of chronic hepatitis C virus (HCV) infection, in combination with Peg-IFN (pegylated interferon) and RBV (ribavirin). About 30% of all HIV infected patients are co-infected with HCV and need treatment for both infections. The results of this study will provide dosing recommendations for coadministration of TMC435 and efavirenz or raltegravir in HIV-HCV co-infected patients. This is a Phase I, open-label (both participant and investigator know the name of the medication given at certain moment), randomized (sequence of treatment with study medications is assigned by chance), crossover trial in 48 healthy volunteers to investigate the pharmacokinetic interaction between TMC435 and an antiretroviral agent (efavirenz or raltegravir), at steady state. The volunteers are being allocated to one of two panels. In Panel 1, volunteers will receive three treatments (treatment A-B-C) in a randomized order. Volunteers will receive TMC435 150 mg q.d., efavirenz 600 mg q.d. and efavirenz 600 mg q.d. + TMC435 150 mg q.d., respectively. All treatments will be administered for 14 days. There will be a washout period (a period where no study drug will be taken in view of having all the medication eliminated from the body before starting a new treatment) of at least 14 days between last intake of study medication in one session and first intake of study medication in the subsequent session. In Panel 2, volunteers will receive three treatments (treatment D-E-F) in a randomized order. Volunteers will receive TMC435 150 mg q.d., raltegravir 400 mg b.i.d. and raltegravir 400 mg b.i.d. + TMC435 150 mg q.d., respectively. All treatments will be administered for 7 days. There will be a washout period of at least 7 days. Pharmacokinetic profiles of all three compounds will be determined through blood samples taken at regular intervals during the study. Safety and tolerability will be assessed during the study period and in follow-up. Blood and urine samples, electrocardiogram (ECG) and vital signs (blood pressure and heart rate) will be taken at screening, before medication intake on Days 1 and 14 and on Day 15 in each session of Panel 1, before medication intake on Days 1 and 7 and on Day8 in each session of Panel 2, 6 hours post dose on Day14 and Day7 in Panel 1 and 2, respectively and at the 2 follow up visits at 1 week and 4-5 weeks after last dose of study medication in the last session. A physical examination will be performed at screening, on Day-1 (= day before first medication intake in each session for both panels) and on Day15 in Panel 1, on Day-1 and on Day8 of Panel 2 and during the 2 follow up visits. Each volunteer will receive 3 treatments for 14 or 7 days (Panel 1 and 2, respectively), minimum 14 or 7 days apart from each other (Panel 1 and 2, respectively). Volunteers in Panel 1 will take oral TMC435 150 mg q.d., oral efavirenz 600 mg q.d. and combined. Volunteers in Panel 2 will take oral TMC435 150 mg q.d., oral raltegravir 400 mg b.i.d. and combined.
