Study in HCV-Infected Patients to Determine the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of JNJ-47910382

9. maj 2014 opdateret af: Janssen R&D Ireland

A Phase Ib, Randomized, Double-Blind, Placebo-Controlled Trial in Caucasian Genotype 1 Chronic HCV-Infected Subjects to Determine the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of Repeated Doses of JNJ-47910382 Given in Different Doses and Dose Regimens

The purpose of this study is to determine the safety, tolerability, pharmacokinetics (what the body does to the medication) and antiviral activity of JNJ-47910382 when administered in different dosing regimens in Caucasian genotype-1 chronic HCV-infected patients.

Detaljeret beskrivelse

This is a Phase Ib, double-blind (neither physician nor patient knows the treatment that the patient receives), randomized (the study drug is assigned by chance), placebo-controlled study in treatment-naïve (someone who has never used drugs for HCV infection), Caucasian genotype 1 chronic HCV-infected patients. The study consists of a screening period, a 9-day treatment period (with 5 days of actual medication intake) and a 4-week follow-up period. The patients will be divided over 4 panels of 10 patients each that will be initiated sequentially. In each panel patients will receive JNJ-47910382 or placebo during 5 consecutive days. JNJ-47910382 or placebo will be administered once daily or twice daily. Within each panel, 5 patients of genotype-1a and 5 patients of genotype-1b will be enrolled. Patients will be randomly assigned to receive active treatment or placebo in such a way that 4 patients of each genotype receive active treatment and 1 subject of each genotype receives placebo. The pharmacokinetic profile of JNJ-47910382 will be assessed in each panel. HCV RNA kinetics (HCV RNA level) and HCV resistance will be studied and biomarkers at the messenger RNA (mRNA), protein and cell level will be explored. The entire study duration for each participant will be approximately four weeks.
