VX-950-TiDP24-C133 - A Phase I Study Investigating the Interaction Between Telaprevir and Escitalopram
2010年12月16日 更新者:Tibotec BVBA
A Phase I, Open-label, Randomized, Crossover Trial in 16 Healthy Subjects to Investigate the Potential Pharmacokinetic Interaction Between Telaprevir and Escitalopram at Steady-state
The purpose of this study is to investigate the effect of steady-state telaprevir (TVR) 750 mg q8h (3 times a day, every 8 hours) on the steady-state pharmacokinetics of escitalopram 10 mg q.d.
(once a day), 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.
TVR is being investigated for the treatment of chronic hepatitis C virus (HCV) infection.
Pharmacokinetics (pk) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.
調査の概要
詳細な説明
Telaprevir is being investigated for treatment of chronic HCV infection, in combination with Peg-IFN (pegylated interferon) and RBV (ribavirin).
Peg-IFN plus RBV are currently an accepted methode for treating HCV.
Treatment with Peg-IFN plus RBV for HCV infection is associated with a high rate of depression.
The results of this study will provide dosing recommendations for coadministration of Telaprevir (TVR) and escitalopram in HCV-infected patients.
This is a Phase I, open-label (both participant and investigator know the name of the medication), randomized (study medication assigned by chance), crossover trial in 16 healthy participants to investigate the pharmacokinetic interaction between escitalopram and TVR, both at steady state.
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.
The participants will receive two treatments (treatment A-B or treatment B-A) in a randomized order.
In Treatment A, participants will receive escitalopram 10 mg once daily (q.d.) for 7 days.
In Treatment B, participants will receive TVR 750 mg every 8 hours (q8h) for 14 days, with coadministration of escitalopram 10 mg q.d.
from Day 8 to Day 14.
There will be a washout period (a period where no treatment 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.
All study medication will be taken with food.
Escitalopram will be taken once daily in the morning.
During coadministration of TVR and escitalopram, the first dose of TVR should be taken together with escitalopram in the morning.
Pharmacokinetic profiles of the two compounds will be measured through blood samples taken at regular intervals during the study and safety and tolerability will be assessed during the study period and in follow-up.
Safety and tolerability evaluations will be recorded at regular intervals throughout the trial period.
Blood and urine samples, electrocardiogram (ECG) and vital signs (blood pressure and hart rate) will be taken at screening, before medication intake on days 1 and 7 in each session and on day 14 in treatment B and at the 2 follow up visits at 5-7 and 30-32 days after last dose of drug in the last session.
A physical examination will be performed at screening, on day before first medication intake in each session and during the 2 follow up visits.
Participants in Treatment A will receive oral escitalopram 10 mg once daily for 7 days and in Treatment B participants will receive TVR 750 mg q8h from Day 1 to Day 14, with coadministration of escitalopram 10 mg q.d.
from Day 8 to Day 14.
