E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To show that concomitant use of telaprevir (1125 mg BID) does not lead to a relevant decrease (> 20%) in the paroxetine parameter AUC0-24h compared to paroxetine alone. |
|
E.2.2 | Secondary objectives of the trial |
To determine the ratio of the geometric means (medians) of the paroxetine PK parameters Cmax and C24h for the combination therapy of telaprevir (1125 mg BID) and paroxetine (20 mg QD) versus paroxetine (20 mg QD) alone.
To determine the short-term safety of combined use of paroxetine 20mg QD with telaprevir-containing HCV treatment.
To assess the short-term HCV RNA response of telaprevir-containing HCV treatment (week 4 response) with concomitant use of paroxetine.
To assess telaprevir pharmacokinetics 1125 mg BID (AUC0-12h, Cmax, C12h) when co-administered with paroxetine 20mg QD.
