Condition chronic hepatitis c
Treatments vitamin d +pegylated interferon + ribavirin, pegylated interferon + ribavirin
Phase phase 3
Sponsor Cairo University
Start date May 2012
End date February 2014
Trial size 80 participants
Trial identifier NCT01655966, RAIL002


Chronic hepatitis C is endemic in Egypt with a high prevalence of the resistant genotype 4. Conventional standard of care treatment has modest response with only 50% sustained virologic response. Recent reports have suggested an augmented response with the addition of vitamin D. This is a prospective randomized trial to assess the effectiveness of adding vitamin D to standard of care for chronic hepatitis C genotype 4.

Group A: comprises 40 treatment-naive chronic hepatitis c patients who will receive the standard of care treatment: peginterferon Alfa 2a 160 ug once weekly and weight-based ribavirin 1000 or 1200 mg/day (based on body weight < 75 kg or ≥ 75 kg, respectively) in divided doses for 48 weeks.
pegylated interferon + ribavirin
pegylated interferon 160ug once weekly Ribavirin (> 75kg:1200 mg, <75kg:1000mg daily)48 weeks
Group B: comprises 40 treatment-naive chronic HCV patients who will receive oral vitamin D 1mcg once daily plus peginterferon alfa-2a (160ug once weekly) and weight-based ribavirin 1000-1200 mg daily (based on body weight < 75 kg or ≥ 75 kg, respectively) in divided doses for 48 weeks.
