Trial Outcomes & Findings for Study of HCV Genotype 1 Patients in the UK Treated With ViraferonPeg and Rebetol (Study P05269)(COMPLETED) (NCT NCT00724373)

NCT ID: NCT00724373

Last Updated: 2015-09-25

Results Overview

Identify subgroups of genotype 1 participants to better understand factors affecting response rates \& treatment outcomes \& to provide predictive models of refractory or responsive phenotypes to aid in HCV treatment, management, \& drug development. Treatment success is defined as those who had achieved sustained virological response (i.e. undetectable viraemia 24 weeks post therapy completion).

Recruitment status

COMPLETED

Target enrollment

442 participants

Primary outcome timeframe

Data will be collected from the start of first exposure to pegylated interferon alfa-2b and ribavirin combination therapy. Participants who have successfully completed treatment will have data collected for a follow-up period of at least 24 weeks.

PRIMARY outcome

Timeframe: Data will be collected from the start of first exposure to pegylated interferon alfa-2b and ribavirin combination therapy. Participants who have successfully completed treatment will have data collected for a follow-up period of at least 24 weeks.

Population: Number of participants who had treatment success.

Identify subgroups of genotype 1 participants to better understand factors affecting response rates \& treatment outcomes \& to provide predictive models of refractory or responsive phenotypes to aid in HCV treatment, management, \& drug development. Treatment success is defined as those who had achieved sustained virological response (i.e. undetectable viraemia 24 weeks post therapy completion).
