BIOTHRAX® (Anthrax Vaccine Adsorbed)

Suspension for Intramuscular or Subcutaneous Injection

Initial U.S. Approval: 1970

INGREDIENTS AND EXCIPIENTS

BioThrax® (Anthrax Vaccine Adsorbed) is a sterile, milky-white suspension for intramuscular or subcutaneous injections made from cell-free filtrates of microaerophilic cultures of an avirulent, nonencapsulated strain of Bacillus anthracis. The production cultures are grown in a chemically defined protein-free medium consisting of a mixture of amino acids, vitamins, inorganic salts, and sugars. The final product, prepared from the sterile filtrate culture fluid contains proteins, including the 83kDa protective antigen (PA) protein, released during the growth period and contains no dead or live bacteria. The final product is formulated to contain 1.2 mg/mL aluminum, added as aluminum hydroxide in 0.85% sodium chloride. The final product is formulated to contain 25 mcg/mL benzethonium chloride and 100 mcg/mL formaldehyde, added as preservatives.

INDICATIONS AND USAGE

BioThrax is a vaccine indicated for the active immunization for the prevention of disease caused by Bacillus anthracis in persons 18 through 65 years of age. BioThrax is approved for:

  1. Pre-exposure prophylaxis of disease in persons at high risk of exposure.
  2. Post-exposure prophylaxis of disease following suspected or confirmed Bacillus anthracis exposure, when administered in conjunction with recommended antibacterial drugs.

The efficacy of BioThrax for post-exposure prophylaxis is based solely on studies in animal models of inhalational anthrax. (1)

USE IN SPECIFIC POPULATIONS

Pregnancy Category D. [See Warnings and Precautions (5.3)]

Healthcare practitioners are encouraged to register women who receive BioThrax during pregnancy in Emergent’s vaccination pregnancy registry by calling 1-619-553-9255.

Male Fertility: A retrospective study was performed at an in-vitro fertilization clinic to evaluate whether BioThrax may impact reproductive function in men. This study compared semen parameters, embryo quality, and pregnancy outcomes in 254 male clients who stated that they had received BioThrax, with those of 791 male clients who did not.2 Prior receipt of BioThrax did not influence semen parameters (including concentration, motility, and morphology), fertilization rate, embryo quality or clinical pregnancy rates.

Nursing Mothers

It is not known whether BioThrax is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when BioThrax is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established for BioThrax.

Geriatric Use

BioThrax has not been approved for use in patients greater than 65 years of age.

Pregnancy: Advise women of potential risk to the fetus. (5.3, 8.1) Pregnancy registry available, contact BioThrax (Anthrax) Vaccine in Pregnancy Registry (Phone: 1-619-553-9255). (8.1)
