Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Signed informed consent prior to any study related procedures.
2. Male or female 50 to75 years of age (both inclusive) at screening.
3. Subjects who the Investigator believes will comply with the requirements of the protocol.
4. Judged by the Investigator to have no serious illness based on medical history, physical examination, ECG, vital signs and blood and urine assessments at screening.

Non-menopausal females have to use contraceptive methods with a failure rate of \< 1% to prevent pregnancy (combined \[oestrogen and progestogen containing\] hormonal contraception associated with inhibition of ovulation \[oral, intravaginal, transdermal\], progestogen- only hormonal contraception associated with inhibition of ovulation \[oral, injectable, implantable\], intrauterine device \[IUD\], intrauterine hormone-releasing system \[IUS\], bilateral tubal occlusion, sexual abstinence). Any male partner should be willing to use condom or should be vasectomized.

Exclusion Criteria

7. Diagnosis of asthma with poor disease control as assessed by the Investigator.
8. 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.
9. Use of any parenteral or oral corticosteroids within 30 days prior to screening. Inhaled steroids are allowed.
10. Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.

12. Any history of Guillain-Barré syndrome.

14. Participation in blood donation within 3 months or plasma donation within 1 month prior to Visit 2.

16. History or any illness/condition that, in the opinion of the Investigator, might interfere with the results of the study or pose additional risk to the subjects due to participation in the study.
