FDA approves drug to treat smallpox (Tembexa) (06 04 2021)

The U.S. Food and Drug Administration today approved Tembexa (brincidofovir) to treat smallpox. Although the World Health Organization declared smallpox, a contagious and sometimes fatal infectious disease, eradicated in 1980, there have been longstanding concerns that the virus that causes smallpox, the variola virus, could be used as a bioweapon.

Before its eradication in 1980, the variola virus mainly spread by direct contact among people. Symptoms typically began 10 to 14 days after infection and included fever, exhaustion, headache, and backache. A rash consisting of small, pink bumps progressed to pus-filled sores before it crusted over and scarred. Complications of smallpox included encephalitis (inflammation of the brain), corneal ulcerations (an open sore on the clear, front surface of the eye), and blindness.

Although naturally occurring smallpox no longer exists, concerns about potential uses of variola virus as a bioweapon has made smallpox drug development an important component of the U.S. medical countermeasures response.

Because smallpox is eradicated, the effectiveness of Tembexa was studied in animals infected with viruses that are closely related to the variola virus. Effectiveness was determined by measuring animals’ survival at the end of the studies. More animals treated with Tembexa survived compared to the animals treated with placebo. FDA approved Tembexa under the agency’s Animal Rule, which allows findings from adequate and well-controlled animal efficacy studies to serve as the basis of an approval when it is not feasible or ethical to conduct efficacy trials in humans.

Safety information to support approval of Tembexa was derived from clinical trials of the drug for a non-smallpox indication, primarily from patients who received hematopoietic stem cell transplants. An increased risk of death was seen in another disease (Cytomegalovirus disease - a viral infection) when Tembexa was used for a longer-than-recommended duration (longer than once a week for two weeks on days 1 and 8). Tembexa is only approved for the treatment of smallpox.

The most common side effects when using Tembexa are diarrhea, nausea, vomiting, and abdominal pain.

Tembexa received priority review, fast track and orphan drug designations. Priority review directs overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis or prevention of serious conditions when compared to standard applications. Fast track is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. Orphan drug designation provides incentives to assist and encourage the development of drugs for rare diseases.

Tembexa was developed in conjunction with the U.S. Department of Health and Human Services’ Biomedical Advanced Research and Development Authority (BARDA). FDA granted approval of Tembexa to Chimerix Inc.

There were internet rumors of an outbreak of smallpox in Yemen. I did a search and didn't find any credible sources. I did find this. A drug to treat smallpox was approved last year.

There hasn’t been a case of smallpox in the wild in 45 years.

It was reported that some the Covid vaccines were developed before the disease existed, too. Somebody must know something. Should be fun to see if Ivermectin will work on smallpox.

“It was reported that some the Covid vaccines were developed before the disease existed, too. Somebody must know something. Should be fun to see if Ivermectin will work on smallpox.”

SARS first appeared in the early 2000’s.

One of Fauci’s failures is to not have come up with a treatment to have ready if there were ever an epidemic.

That’s his job. Utter derelection of duty.

maybe Fauci has another lab somewhere working on Gain of Function with this virus. For research purposes only, ya' unnerstan.

My wife and I watched the smallpox scene in “1883” and she remarked that their treatment of the infected guy was “pretty extreme.” I face palmed.
