  • Increased liver enzymes more than 2.5 times above the upper reference level.
  • Positive serology for HIV, HCV antibody or HBsAg.
  • Any acute medical situation (e.g. acute infection, ongoing flu symptoms) with or without fever within 48 hours of vaccination, which is considered of significance by the Principal Investigator.
  • Pregnant or lactating women at entry to study and those who are unwilling to agree to continue to use acceptable methods of contraception for two months after completion of the study (if applicable).

Arm Description

64 subjects received 2 injections of Adjuvanted Multimeric-001, 500 mcg with an interval of 21 days and then 60 days later were further immunized with a 15% dose of commercial seasonal trivalent vaccine (season 2011).

32 subjects received 2 injections of PBS (Phosphate Buffered Saline) with an interval of 21 days and then were further immunized 60 days later with a 15% dose of commercial seasonal trivalent vaccine (season 2011).

32 subjects received Adjuvanted PBS (Placebo) with an interval of 21 days.

24 subjects received 2 injections on the same day, one injection containing Adjuvanted Multimeric-001 500 mcg and the other containing TIV 15%.

Outcomes

Primary Outcome Measures

Number of Participants with Adverse Events as a Measure of Safety and Tolerability
Number of Participants with Adverse Events possible/probably related to the study drug in each group were similar in the experimental and control groups.
Anti Multimeric-001 antibodies
Direct Elisa assay to test the titer of human antibodies that recognize the Multimeric-001 protein. Humoral immunity was manifested 21 and 60 days post immunization by significantly elevated anti-M-001 IgG levels among subjects administered twice with adjuvanted M-001

Secondary Outcome Measures

Hemagglutination Inhibition (HAI) test for anti influenza antibodies
The serum is tested for its ability to adhere to influenza virus and thus inhibit the Hemagglutination reaction. Adjuvanted M-001 co-administered with partial dose of TIV (Vaxigrip, 50%) was effective in enhancing immunity to influenza-related antigens, as manifested by increased HAI antibody responses toward viruses contained in the TIV as well as toward non-TIV virus strains.
