NCT02624219

Brief Summary

This is a Phase I randomized, double-blind, controlled trial in 275 males and non-pregnant females, 19 to 64 years old, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity, and immunogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine manufactured by bioCSL administered at different dosages (7.5 or 15 mcg of HA/0.5 mL dose) given with or without AS03 or MF59 adjuvants manufactured by GlaxoSmithKline Biologicals and Novartis Vaccines and Diagnostics, respectively.

You may not qualify if:

  • \. Have an acute illness\*, as determined by the site principal investigator or appropriate sub-investigator, within 72 hours prior to study vaccination. \*An acute illness which is nearly resolved with only minor residual symptoms remaining is allowable if, in the opinion of the site principal investigator or appropriate sub-investigator, the residual symptoms will not interfere with the ability to assess safety parameters as required by the protocol. 2. Have any medical disease or condition that, in the opinion of the site principal investigator or appropriate sub-investigator, is a contraindication to study participation\*\*. \*\*Including acute or chronic medical disease or condition, defined as persisting for at least 90 days, that would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or may interfere with the evaluation of responses or the subject's successful completion of this trial. 3. Have immunosuppression as a result of an underlying illness or treatment, or use of anticancer chemotherapy or radiation therapy (cytotoxic) within 3 years prior to study vaccination. 4. Have known active neoplastic disease or a history of any hematologic malignancy. Non-melanoma skin cancers are permitted. 5.

Refer as well to the list of AESIs. 12. Have a history of alcohol or drug abuse within 5 years prior to study vaccination. 13. Have any diagnosis, current or past, of schizophrenia, bipolar disease, or other psychiatric diagnosis that may interfere with subject compliance or safety evaluations. 14.

Have taken oral or parenteral (including intraarticular) corticosteroids of any dose within 30 days prior to study vaccination. 16. Have taken high-dose inhaled corticosteroids within 30 days prior to study vaccination. High-dose defined as \>840 mcg/day of beclomethasone dipropionate CFC or equivalent. 17. Received a licensed live vaccine within 30 days prior to the first study vaccination, or plan to receive a licensed live vaccine within 30 days before or after each study vaccination. 18. Received a licensed inactivated vaccine within 14 days prior to the first study vaccination, or plan to receive a licensed inactivated vaccine within 14 days before or after each study vaccination. 19. Received immunoglobulin or other blood products (with exception of Rho D immunoglobulin) within 90 days prior to study vaccination. 20. Received an experimental agent7 within 30 days prior to the first study vaccination, or expect to receive an experimental agent8 during the 13-month trial-reporting period. 7Including vaccine, drug, biologic, device, blood product, or medication. 8Other than from participation in this trial. 21. Are participating or plan to participate in another clinical trial with an interventional agent\*\*\*\* that will be received during the 13-month trial-reporting period. \*\*\*\*Including licensed or unlicensed vaccine, drug, biologic, device, blood product, or medication. 22. Prior participation in a clinical trial of influenza A/H5 vaccine\*\*\*\*\* or have a history of influenza A/H5 virus actual or potential exposure or infection prior to the first study vaccination. \*\*\*\*\*And assigned to a group receiving influenza A/H5 vaccine, does not apply to documented placebo recipients. 23. Occupational exposure to or substantial direct physical contact (Note) with birds in the past year or during the 21 days after each study vaccination. Note: Casual contact with birds at petting zoos, county or state fairs, or having pet birds does not exclude subjects from study participation. 24. Female subjects who are breastfeeding or plan to breastfeed at any given time from the first study vaccination until 30 days after the last study vaccination. 25. Plan to travel outside the US (continental US, Hawaii, and Alaska) within 21 days after each study vaccination.
