A Study of Drug-drug Interaction Between Ritonavir and TMC435350 in Healthy Volunteers
11. oktober 2013 opdateret af: Tibotec Pharmaceuticals, Ireland
Phase I, Open-label Trial in Healthy Subjects to Evaluate the Drug-drug Interaction Between Ritonavir at Steady-state and TMC435350, a Viral Protease Inhibitor Against Hepatitis C Virus, After the First and the Last Dose of a Multiple Dosing Regimen
The purpose of this study is to evaluate the drug-drug interaction between steady-state concentrations of CYP3A4 or ritonavir and TMC435350 after its first and the last dose of the multiple dosing regimen and to explore the short term safety and tolerability of multiple doses of 200 mg of TMC435350 administered alone and in combination with 100 mg of ritonavir.

Detaljeret beskrivelse
This trial is a Phase I, open label trial (meaning that both the research physician and study participants will know which medication is being administered during the trial) in 12 healthy volunteers (referred to as participants) to investigate the effect of ritonavir, a marketed product used in several HIV medications, on the plasma levels of TMC435350, a new investigational drug in process of development for the treatment of hepatitis-C virus (HCV) infections.
TMC435350 is a protease inhibitor (PI), a class of drugs that selectively inhibit the replication of the virus thereby inhibiting the progression of HCV infection.
Plasma levels of TMC435350 are circulating levels of TMC435350 in the blood that are important for the antiviral activity of TMC435350.
Ritonavir has the ability to increase the circulating levels of other compounds administered on the same day as Ritonavir.
The trial will consist of 2 sequential sessions (Session 1 and Session 2) and all participants enrolled in the study will enter each session.
In Session 1, participants will take TMC435350 200mg orally (by mouth) once daily for 7 days.
There will be a waiting period of at least 7 days to allow any drug left in the body after the last treatment in Session 1 to be eliminated before the start of Session 2 (referred to as a "washout period").
In Session 2, participants will take ritonavir 100 mg orally twice daily on Days 1 to 15 and TMC435350 200mg once daily on Days 6 to 12.
All study drugs in both treatment sessions will be taken under fed conditions (i. e., participants will eat a standard breakfast within approximately 30 minutes before they take study drug).
Full pharmacokinetic profiles of TMC435350 (to investigate how the drug moves through the body, including the absorption, distribution, metabolism and elimination of the drug) will be determined from blood samples obtained on Days 1 and 7 of Session 1 and on Days 6 and 12 of Session 2. Safety and tolerability will be recorded continuously.
The total duration of treatment in the study for each participant will be approximately 30 days (includes 7 days of treatment in Session 1, 16 days of treatment in Session 2, and a washout period of at least 7 days between treatment sessions).
