Antioxidant and Immunomodulator Properties of Viusid in Patients With Chronic Hepatitis C
This study is currently recruiting participants.
Verified by Catalysis SL, October 2008
Sponsored by: Catalysis SL
Information provided by: Catalysis SL
ClinicalTrials.gov Identifier: NCT00778843
  Purpose

The pathogenesis of chronic hepatitis C (CHC) is associated to severe oxidative stress and non-selective immunological disturbance that leads to necro-inflammation and progression of fibrosis. Previous trials suggested that antioxidant and inmunostimulant therapies may have a beneficial effect. The purpose of the study is to evaluate whether Viusid, a nutritional supplement with hepatoprotective properties, could ameliorate the oxidative stress and modulate the immune response in patients with CHC and non-responders to pegylated interferon plus ribavirin, during 24 weeks of treatment.

Further study details as provided by Catalysis SL:

Primary Outcome Measures:
  • The improvement of serum parameters related to oxidative stress (SOD, AT, MDA, MDA/HNE, GPx, GR, AOP, MPO, PAOP, GSH) at 24 weeks (end of the treatment). [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • The improvement of serum parameters related to immune response (IFN alpha, IFN gamma, IL-1 alpha, IL-2, IL-6, IL-10, IL-12, TNF alpha, Anti TNF alpha, Cathepsin L) at 24 weeks (end of the treatment). [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Improvement of aminotransferase levels (ALAT and ASAT) at 24 weeks (end of the treatment). [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Improvement of clinical symptoms and signs at 24 weeks (end of the treatment). [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
