Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with Sustained virologic response (SVR)	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.	24w after completing Peg/RBV
Secondary	Number of participants with End of treatment response (ETR)	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	48 weeks at Genotype 1, 24 weeks at Genotye 2 and 3
Secondary	Number of participants with Rapid virological response (RVR)	Compare the number of participants with HCV RNA is notdetectable in the blood at week 4 of treatment between vitamin and control group	Week 4
Secondary	Number of participants with Early virological response (EVR)	Compare the number of participants with HCV RNA cannot be detected in the blood at week 12 of treatment between viatmin and control group	Week 12
