Study summary

This study is designed to determine the optimal dose of JVRS-100 and assess safety, tolerability and immunogenicity of Fluzone® vaccine administered with JVRS-100 adjuvant at one of three dose levels compared to Fluzone® vaccine administered alone, in 472 adults aged ≥65 years.

Read the detailed description

Approximately 472 subjects will be enrolled in this study. The study population will include elderly male and female subjects aged ≥65 years who are living in the community (including assisted living environments) and who are very fit to moderately frail.

One hundred subjects (approximately 25 in each treatment arms) will be vaccinated, and 14 days will elapse during which safety parameters are monitored by a Data and Safety Monitoring Board (DSMB), before randomizing the remaining 372 subjects.

What researchers measure

Primary outcomes

  1. Safety: The primary safety endpoint of this trial will be the evaluation of adverse events incidence rates between treatment groups.

    Time frame: Active Study Duration

  2. Immunogenicity: Dose-response analysis of HAI geometric mean titers (GMT)

    Time frame: Day 0, 21, 28, Month 4 and 9

Secondary outcomes

  1. Safety: Comparison of AE rates at intervals between treatment groups.

    Time frame: Active Study Duration

  2. Immunogenicity: Comparison of Fluzone® with JVRS-100 by examining seroprotection and seroconversion rates to various antigens, duration of HAI antibody titers, and assessment of cross-reactive HAI responses against drifted strains.

    Time frame: Day 0, 21, 28 and Month 4 and 9

  3. T-cell responses will be measured.

    Time frame: Day 0, 7, 14 and 28
