简要总结
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.
详细描述
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 which include screening hematology, chemistry and erythrocyte sedimentation rate (ESR) laboratory evaluations. 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. The primary objectives of this study is to assess 1) the safety and reactogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine and 2) the serum hemagglutination inhibition (HAI) and neutralizing (Neut) antibody responses to a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of two doses administered intramuscularly at different dosages (7.5 or 15 mcg of HA/0.5 mL dose) given with or without AS03 or MF59 approximately 21 days apart. The secondary objectives of this study are to 1) assess study vaccine-related unsolicited non-serious adverse events following receipt of two doses of a monovalent inactivated influenza A/H5N8 virus vaccine, 2) assess medically attended adverse events (MAAEs) including new-onset chronic medical conditions and immune-mediated or auto-inflammatory adverse events of special interest following receipt of two doses of a monovalent inactivated influenza A/H5N8 virus vaccine, and 3) assess the serum HAI and Neut antibody responses to a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of one dose administered intramuscularly at different dosages (7.5 or 15 mcg of HA/0.5 mL dose) given with or without AS03 or MF59. This study will span approximately 24 months. Subject participation duration will span approximately 13 months.

入选标准
- •Provide written informed consent prior to initiation of any study procedures.
- •Are able to understand and comply with planned study procedures and be available for all study visits.
- •Are males or non-pregnant females, 19 to 64 years old, inclusive.
- •Are in good health. Note: As determined by medical history and physical examination to evaluate acute or currently ongoing chronic medical diagnoses or conditions, defined as those that have been present for at least 90 days, that would affect the assessment of the safety of subjects or the immunogenicity of study vaccinations. Chronic medical diagnoses or conditions should be stable for the last 60 days. This includes no change in chronic prescription medication, dose, or frequency as a result of deterioration of the chronic medical diagnosis or condition in the 60 days prior to enrollment. Any prescription change that is due to change of health care provider, insurance company, etc., or that is done for financial reasons, as long as in the same class of medication, will not be considered a deviation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome, as determined by the site principal investigator or appropriate sub-investigator, will not be considered a deviation of this inclusion criterion. Subjects may be on chronic or as needed (prn) medications if, in the opinion of the site principal investigator or appropriate sub-investigator, they pose no additional risk to subject safety or assessment of reactogenicity and immunogenicity and do not indicate a worsening of medical diagnosis or condition. Similarly, medication changes subsequent to enrollment and study vaccination are acceptable provided there was no deterioration in the subject's chronic medical condition that necessitated a medication change, and there is no additional risk to the subject or interference with the evaluation of responses to study vaccination. Note: Topical, nasal, and inhaled medications (with the exception of inhaled corticosteroids as outlined in the Subject Exclusion Criteria (see Section 5.1.2)), herbals, vitamins, and supplements are permitted.
