Anthrax AV7909 Boost Evaluation Study

Exclusion Criteria

• •1. Has an acute illness, as determined by the site investigator, within 72 hours prior to study IP administration.
• •* An acute illness that is nearly resolved, with only minor residual symptoms remaining, is allowable if, in the opinion of the site investigator, the residual symptoms will not interfere with the ability of study staff to assess safety parameters as required by the protocol.
• •* If the subject's temperature is above 100.4°F, indicating illness, the subject may be re-assessed for eligibility a minimum of 24 hours later.
• •2. Has a history of severe reactions to components of AV7909.
• •3. Has a history of anthrax disease, suspected exposure to anthrax, or previous vaccination with any anthrax vaccine.
• •4. Has recently diagnosed or poorly controlled human immunodeficiency virus (HIV).
• •5. Has an acute or chronic hepatitis B or hepatitis C infection, as identified through laboratory testing.
• •\- A subject who has been effectively treated for hepatitis C, as evidenced by a negative hepatitis C ribonucleic acid (RNA) confirmation test, and who no longer requires antiviral therapy is not excluded.
• •6. Is suffering from or has a history of neuralgia, paresthesia, neuritis, convulsions, or encephalomyelitis within 90 days prior to Screening, or a family history of Guillain-Barré syndrome.
• •7. Has a history of alcohol or drug abuse within 5 years prior to Screening.
• •8. Has any diagnosis, current or past, of schizophrenia, bipolar disease, or any other psychiatric diagnosis that may, in the opinion of the site investigator, interfere with subject compliance or safety evaluations.
• •9. Is taking herbal medicines/preparations that are known to have a direct or indirect effect on the immune system.
• •10. Presence of tattoos on both upper arms that would cover or partially cover all potential vaccination sites.
• •11. Clinically relevant signs of pathology or conduction disturbances documented by electrocardiogram (EKG).
• •12. Has taken corticosteroids as follows within 30 days prior to Screening.
• •* Oral or parenteral corticosteroids at a dose of ≥20 mg daily and/or
• •* High-dose (\>800 mcg/day of beclomethasone di-iso-propionate chlorofluorocarbon \[CFC\] or equivalent) inhaled corticosteroids.
• •13. Female of childbearing potential who has a positive urine pregnancy test or who is currently breastfeeding.
• •14. Has had any vaccination (licensed or under Emergency Use Authorization \[EUA\]; any type) within the 30 days prior to the planned first study IP administration.
• •15. Is immunosuppressed due to an underlying disease or medication, use of anticancer chemotherapy (cytotoxic), or radiation therapy.
• •16. With the exception of basal or squamous cell skin cancer, has known active neoplastic disease, including hematologic malignancy.
• •17. Has received an investigational agent within 30 days prior to the planned first study IP administration.
• •18. Has any laboratory test result or clinical findings (including vital signs) that singly or in combination are likely to unfavorably alter the risks of subject participation or to confound study safety or immunogenicity results, in the opinion of the site investigator. Additionally, the following are exclusionary:
• •1. Has any clinically significant Grade 3 laboratory or vital sign result, or any Grade 4 laboratory or vital sign result (regardless of assessed significance) at Screening.
• •2. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>2 times the upper limit of normal (ULN), or bilirubin \>1.5 times the ULN unless isolated Gilbert's syndrome.
• •3. Creatinine \>1.5 times ULN for age and sex.
• •4. White blood cell count \<3,000/µL or \>12,500/µL; absolute neutrophil count \<1,200/µL; absolute lymphocyte count \<750/µL; hemoglobin \<10 g/dL females, or \<11.5 g/dL males; platelet count \<75,000/µL.
• •5. Hemoglobin A1c (HbA1c) \>7.0% at Screening.
• •19. Has any disease or medical condition that, in the opinion of the site investigator, might confound interpretation of safety or immunogenicity.
