Standard therapy for chronic hepatitis C virus (HCV) is (Peg/RBV) combination therapy obtaining sustained virologic response (SVR) in 77% of naïve patients with genotype 1-3 Studies rarely address the issues of improving host factors. The current study examines whether adding vitamin D with Peg/RBV, a potent immunomodulator, could improve viral response(SVR)compared to Peg/RBV.

Condition Intervention Phase
Chronic Hepatitis C
Dietary Supplement: Vit D
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Randomized, Multi-center, Phase IV Open-label Study Evaluating the Antiviral Efficacy of Addition of Vitamin D in Patients With Treatment Naïve Chronic Hepatitis C Receiving Peginterferon Alfa-2a Plus Ribavirin

Primary Outcome Measures:
  • Number of participants with Sustained virologic response (SVR) [ Time Frame: 24w after completing Peg/RBV ] [ Designated as safety issue: No ]
    Compare the number of participants with HCV RNA is not detected in the blood at 24 weeks post-treatment between vitamin D and control group.

Secondary Outcome Measures:
  • Number of participants with End of treatment response (ETR) [ Time Frame: 48 weeks at Genotype 1, 24 weeks at Genotye 2 and 3 ] [ Designated as safety issue: No ]

    Compare the number of participants with HCV RNA is not detected in the blood at the end of treatment between two groups.

    HCV RNA pCR perform at 48 weeks in genotye 1, at 24 weeks in Genotye 2 and 3

  • Number of participants with Rapid virological response (RVR) [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Compare the number of participants with HCV RNA is notdetectable in the blood at week 4 of treatment between vitamin and control group

  • Number of participants with Early virological response (EVR) [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Compare the number of participants with HCV RNA cannot be detected in the blood at week 12 of treatment between viatmin and control group

Estimated Enrollment: 222
Study Start Date: September 2011
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Peginterferon alfa 2a+Ribavirin
standard of care for HCV : peginterferon alfa 2a and ribavirin
Experimental: Vit D+Peginterferon alfa 2a+Ribavirin
VitD+Peginterferon alfa 2a+Ribavirin
Dietary Supplement: Vit D

Detailed Description:
The working hypothesis is that Adding vitamin D to conventional Peg/RBV therapy for naïve, genotype 1-3 patients with chronic HCV infection significantly improves RVR, EVR additionally.
