A Phase I Randomized, Observer-Blinded, Placebo-Controlled Study to Evaluate the Safety, Tolerability and Immunogenicity of Chiron Corporation's HCV E1E2/MF59 Vaccine Administered to Healthy HCV-Negative Adults
In Brief
A Phase 1 clinical trial evaluating HCV E1E2/MF59 and Placebo for Hepatitis C. Completed, enrolled 60 participants across 1 site.
Detailed Summary
The purposes of this study are to evaluate the safety, tolerability, and effectiveness of a vaccine (the HCV E1/E2/MF59 vaccine) against hepatitis C (HCV). The vaccine will be given to 60 healthy adult volunteers (aged 18-45 years) and the study will compare the immune system (the body's protective response) response to the HCV E1/E2 vaccine given at different dosage levels: 4 micrograms, 20 micrograms, or 100 micrograms in MF59 adjuvant (substance that can improve vaccine effectiveness). The volunteers will be assigned randomly (by chance) to 1 of 4 different groups. Volunteers in each group will receive a shot of the vaccine or a placebo (shot with no medication). Participants will be involved in study related procedures for up to 71 weeks, which includes blood samples, recording symptoms on a diary card, and 4 vaccine or placebo injections.

Interventions
The investigational vaccine contains envelope glycoproteins gpE1 and gpE2 and the adjuvant, MF59. MF59 is a sterile oil-in-water emulsion in a citrate buffer, which comprises 50 percent of the vaccine. The antigen and adjuvant are combined prior to the injection. The volume to be administered is 0.5 mL for all vaccine dose levels. The vaccine has a milky white opacity. Vaccine dosages: 4 mcg, 20 mcg and 100 mcg.
Four doses sterile saline (0.5 mL total volume) at 0, 4, 24, and 28 weeks.
