Brief summary

This was a Phase 1/2, randomized, observer-blinded, active-controlled trial to assess the Safety and Tolerability of a Recombinant Trivalent Nanoparticle Influenza Vaccine (Tri-NIV) with Matrix M1™ Adjuvant in Healthy Older Adults ≥ 60 Years of Age

Detailed description

Study tNIV-E-101 a randomized, observer-blinded, active-controlled trial designed to evaluate the safety and immunogenicity of Novavax's insect cell-derived, egg-free, influenza vaccine (Tri-NIV) based on recombinant HA nanoparticle antigens, representing the 3 major influenza types/subtypes recommended for inclusion in the 2017 - 2018 seasonal influenza vaccine by the World Health Organization (WHO) and the Center for Biologics Evaluation and Research (CBER) Approximately 330 eligible subjects were enrolled and randomized into 1 of 3 treatment groups Each group consisted of approximately 110 subjects total, stratified by age, gender, and history of receipt of the 2016 - 17 influenza vaccine. On Day 0, subjects in Groups A and B were administered an IM injection of NanoFlu at one of two dose levels; subjects in Group C received the preconfigured comparator (Fluzone HD) at the manufacturer's recommended dose and volume. On Day 21, all Group A and B subjects were administered a rescue injection with a licensed seasonal influenza vaccine. In contrast, all Group C subjects were administered an injection with a sterile saline placebo to maintain the trial blind. Trial follow-up for each subject spanned approximately 1 year from Day 0.

Inclusion criteria

1. Healthy older adults, male or female, 2. Willing and able to give informed consent prior to trial enrollment, and 3. Able to attend trial visits, comply with trial requirements, and provide reliable and complete reports of adverse events.

Exclusion criteria

1. Any ongoing, symptomatic acute or chronic illness requiring medical or surgical care. * Asymptomatic chronic conditions or findings (eg, mild hypertension, dyslipidemia) that are not associated with evidence of end-organ damage are not exclusionary provided that they are being appropriately managed and are clinically stable (ie, unlikely to result in symptomatic illness within the time-course of this trial) in the opinion of the investigator. * Acute or chronic illnesses or conditions which may be reasonably predicted to become symptomatic if treatment were withdrawn or interrupted are exclusionary, even if stable. * Acute or chronic illnesses reasonably expected to be associated with increased risks in the event of influenza infection (eg, cardio-pulmonary diseases, diabetes mellitus, renal or hepatic dysfunction, hemoglobinopathies) are exclusionary, even if stable. * Note that illnesses or conditions may be exclusionary, even if otherwise stable, due to therapies used to treat them (see
