About TEMBEXA^®
TEMBEXA^® is an oral antiviral approved by the FDA in June 2021 for the treatment of human smallpox disease caused by variola virus in adult and pediatric patients, including neonates. TEMBEXA^® is formulated as 100 mg tablets and 10 mg/mL oral suspension dosed once weekly for two weeks. The oral suspension formulation is particularly important for patients who have difficulty swallowing due to age or medical status.

Important Information about TEMBEXA® (brincidofovir)
TEMBEXA^® is an orthopoxvirus nucleotide analog DNA polymerase inhibitor and is indicated for the treatment of human smallpox disease in adult and pediatric patients, including neonates.

Limitations of Use: TEMBEXA^® is not indicated for the treatment of diseases other than human smallpox disease. The effectiveness of TEMBEXA^® for the treatment of smallpox disease has not been determined in humans because adequate and well-controlled field trials have not been feasible and inducing smallpox disease in humans to study the drug’s efficacy is not ethical. TEMBEXA^® efficacy may be reduced in immunocompromised patients based on studies in immune deficient animals.

TEMBEXA^® has a BOXED WARNING for increased risk for mortality when used for longer duration. An increased incidence of mortality was seen in TEMBEXA^®-treated subjects compared to placebo-treated subjects in a 24-week clinical trial when TEMBEXA^® was evaluated in another disease.

The Warnings and Precautions for TEMBEXA^® include:

• Elevations in Hepatic Transaminases and Bilirubin: May cause increases in serum transaminases (ALT or AST) and serum bilirubin. Monitor liver laboratory parameters before and during treatment.
• Diarrhea and Other Gastrointestinal Adverse Events: Diarrhea and additional gastrointestinal adverse events including nausea, vomiting, and abdominal pain may occur. Monitor patients, provide supportive care, and if necessary, do not give the second and final dose of TEMBEXA^®.
• Coadministration with Related Products: TEMBEXA^® should not be coadministered with intravenous cidofovir.
• Embryo-fetal Toxicity: May cause fetal harm. Advise individuals of childbearing potential of the potential risk to the fetus and to use effective contraception.
• Carcinogenicity: TEMBEXA^® should be considered a potential human carcinogen. Do not crush or divide TEMBEXA^® tablets.
• Male Infertility: Based on testicular toxicity in animal studies, TEMBEXA^® may irreversibly impair fertility in individuals of reproductive potential.

Common adverse reactions (occurring in at least 2% of TEMBEXA^®-treated subjects) were diarrhea, nausea, vomiting, and abdominal pain.

About Smallpox
Smallpox is a highly contagious disease caused by the variola virus. Historically, smallpox was one of the deadliest diseases in history with a case fatality rate of approximately 30 percent. Despite successful eradication of smallpox in the 1970s, there is considerable concern that variola virus could reappear, either through accidental release or as a weapon of bioterrorism. According to the U.S. Centers for Disease Control and Prevention, variola virus is ranked in the highest risk category for bioterrorism agents (Category A) due to its ease of transmission, high mortality rate, and potential to cause public panic and social disruption. Based on a recent report – The Department of Health and Human Services Fiscal Year 2023 Public Health and Social Services Emergency Fund Justification of Estimates for Appropriations Committee – smallpox remains a threat of high concern to both the domestic and international community.
