A Study to Assess the Safety and Immunogenicity of M-001 Influenza Vaccine as a Primer to TIV in Elderly Volunteers

Summary

"Multimeric-001" (M-001) has been recently developed, containing conserved, common linear influenza epitopes that activate both cellular and humoral arms of the immune system against a wide variety of influenza A and B strains. Apart from its direct action, M-001 is an attractive candidate for priming immune responses to seasonal influenza vaccine in the elderly population. The current clinical study was designed to assess M-001's standalone and priming action in subjects over 65 years old. This is a second Phase II study comprising 120 participants. Eligible subjects were randomized to receive to receive either two sequential non-adjuvanted or a single non-adjuvanted or a single adjuvanted intramuscular injection of 500 mcg M-001 (treatment), or one placebo (saline) injection, before receiving the TIV.
