H5N8 Mix and Match With or Without AS03 or MF59 in Healthy Adults: Immunology

Completed · Phase 1

Conditions studied: Avian Influenza

In brief

This is a Phase I cohort-randomized, double-blind, controlled trial designed to assess the safety, reactogenicity, and immunogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine administered at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants. This study will be conducted at 6 sites and enroll 150 (up to 380) males and non-pregnant females, 19 to 64 years old, inclusive who are in good health and meet all eligibility criteria. The entire study duration is approximately 24 months and each subject participation duration is approximately 13 months. The primary objectives are: 1) To assess the safety and reactogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of two doses administered intramuscularly at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants approximately 21 days apart. 2) To assess the serum HAI and Neut antibody responses to a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of two doses administered intramuscularly at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants approximately 21 days apart.

Who can join

Age: 19 and older, up to 64. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• 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.
• 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.
• Oral temperature is less than 100.0°F.
• Pulse is 50 to 115 bpm, inclusive.
• Systolic blood pressure is 85 to 150 mmHg, inclusive.
• Diastolic blood pressure is 55 to 95 mmHg, inclusive.
• Erythrocyte sedimentation rate (ESR) is less than 30 mm per hour.
• Alanine aminotransferase (ALT) is less than 44 IU/L for females or is less than 61 IU/L for males.
• Creatinine is less than 1.11 mg/dL for females or is less than 1.38 mg/dL for males.
• White blood cells (WBC) are greater than 3.9 x10\^3/µL and less than 10.6 x10\^3/µL.
• Hemoglobin (Hgb) is greater than 11.4 g/dL for females or is greater than 12.4 g/dL for males.
• Platelets are greater than 139 x10\^3/µL and less than 416 x10\^3/µL.
• Total bilirubin is less than 1.3 mg/dL.
• Women of childbearing potential must use an acceptable contraception method from 30 days before first study vaccination until 60 days after last study vaccination.
• Not sterilized via tubal ligation, bilateral oophorectomy, hysterectomy, or successful Essure® placement (permanent, non-surgical, non-hormonal sterilization) with documented radiological confirmation test at least 90 days after the procedure, and still menstruating or < 1 year of the last menses if menopausal.
• Includes, but is not limited to, non-male sexual relationships, abstinence from sexual intercourse with a male partner, monogamous relationship with vasectomized partner who has been vasectomized for 180 days or more prior to the subject receiving the first study vaccination, barrier methods such as condoms or diaphragms with spermicide or foam, effective intrauterine devices, NuvaRing®, and licensed hormonal methods such as implants, injectables, or oral contraceptives ("the pill).
• Women of childbearing potential must have a negative urine or serum pregnancy test within 24 hours prior to study vaccination.

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.
• 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.
