NCT03437304

Brief Summary

This is a Phase I/II, randomised, multicentre, partially double-blind (group 1, 2, 4 and 5), parallel-group study designed to primarily evaluate the safety, tolerability and immune response in older adults (age 50 to 75 years) following Immunose™ FLU vaccination at 5 sites in Sweden. A total of 300 subjects will be randomised to 1 of 7 treatment groups. The hypothesis is that Immunose™ FLU is safe and tolerable and will increase the influenza-specific mucosal immune response in older adults.

  • Diagnosis of laboratory-confirmed influenza in the 2017/2018 season.
  • Use of any investigational drug product within 3 months before screening or planned use during the study period, including the safety follow-up period.

  • History of any anaphylactic reaction and/or serious allergic reaction following a vaccination, a proven hypersensitivity to any component of the study vaccine (e.g., to eggs or egg product as well as ovalbumin, chicken protein, chicken feathers, influenza viral protein, kanamycin, gentamycin, neomycin sulphate, formaldehyde and sodium deoxycholate).
  • Diagnosis of asthma with poor disease control as assessed by the Investigator.
  • Potent immunosuppressive therapy including cytostatics, antibodies, drugs acting on immunophilins, interferons and other drugs used to prevent rejection of organ transplants, within 6 months before screening.
  • Use of any parenteral or oral corticosteroids within 30 days prior to screening. Inhaled steroids are allowed.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
  • Any progressive or severe neurologic disorder, seizure disorder or Guillain-Barré syndrome.
  • Any history of Guillain-Barré syndrome.
  • Received blood, blood products and/or plasma derivatives or any administration of immunoglobulin preparation within the 3 months prior to Visit 2, or planned during the study.
  • Participation in blood donation within 3 months or plasma donation within 1 month prior to Visit 2.
  • History of substance or alcohol abuse within the past 2 years.
