| Eligibility |
Inclusion Criteria:
1. Male or non-pregnant females, 18 through 65 years of age, inclusive.
2. Willing and able to provide written informed consent prior to initiation of study
procedures.
3. In relatively stable health, as determined by medical history and physical
examination. Any chronic medical diagnoses or conditions should be stable and well
managed, with no significant changes expected during the study period, and in the
opinion of the site investigator, will not impact the ability to assess safety and/or
immunogenicity per the study design.
4. If a female of childbearing potential who is sexually active, agrees to use an
acceptable method of birth control from Screening to Day 396 and has used a reliable
birth control method for at least 2 months prior to Screening.
1. Female of childbearing potential is defined as post onset menarche and
pre-menopausal person capable of becoming pregnant. This does not include females
who meet any of the following conditions: a) menopausal >2 years; b) tubal
ligation >1 year; c) bilateral salpingo-oophorectomy; or d) hysterectomy.
2. Adequate contraception is defined as a contraceptive method with a failure rate
of less than 1% per year when used consistently and correctly and when
applicable, in accordance with the product label, for example: oral
contraceptives, either combined or progestogen alone; injectable progestogen;
implants of etenogestrel or levonorgestrel; estrogenic vaginal ring; percutaneous
contraceptive patches; intrauterine device or intrauterine system; the female
subject has exclusively female sexual partners; partner is sterile or otherwise
unable to produce sperm (information on the person's sterility can come from the
site personnel's review of the subject's medical records or interview with the
subject regarding her medical history); male condom combined with a vaginal
spermicide (foam, gel, film, cream, or suppository); or male condom combined with
a female diaphragm, either with or without a vaginal spermicide (foam, gel, film,
cream, or suppository).
5. Available for all study visits, willing to participate in all study procedures, and
not planning to relocate from the area for the duration of the study.
6. Has a body mass index (BMI) greater than 18.0 and less than 35.0 kg/m2, inclusive
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.
