For Monkeypox arising a “public health emergency of international concern”, Anhui Poly’s forward-looking layout of Brincidofovir and Tecovirimat APIs, facilitate the prevention and control of monkeypox disease

     Director-General of World Health Organization Tedros declared that the monkeypox arose a “public health emergency of international concern” on August 14. This is the second time in just over two years that the WHO has declared that the monkeypox arose a “public health emergency of international concern”. More than 15,600 monkeypox cases have been reported so far this year, surpassing last year’s total, including 537 deaths, according to the WHO.

     On August 13, the Africa Centres for Disease Control and Prevention declared that the monkeypox epidemic is an African public health emergency and called on African countries to take urgent action to avoid the continued spread of monkeypox on the continent. According to the Africa Centres for Disease Control and Prevention on August 8, at least 16 countries in Africa have been affected by monkeypox outbreaks. Africa has reported 160% more monkeypox cases this year compared to the same period in 2023.

     Anhui Poly’s forward-looking layout of monkeypox disease prevention and control drugs, Brincidofovir and Tecovirimat APIs (self-developed and manufactured), facilitate the prevention and control of monkeypox epidemic.

1、Tecovirimat

爱游戏·(中国)官方网站2.png

     Tecovirimat (also known as ST-246) is a small molecule, broad-spectrum membrane protein inhibitor, by inhibiting the activity of the VP37 protein of the orthopxvirus, preventing the formation of the virus-specific envelope complex, preventing the export of infectious envelope virus particles, thereby inhibiting the transmission of the virus between cells and remote transmission. It has strong activity against orthopoxvirus such as variola virus, monkeypox virus, vaccinia virus and etc.

     Developed by Siga Technologies, Tecovirimat was granted orphan drug status by the FDA for the treatment of poxvirus infections in 2010, and was approved for marketing in 2018 for the treatment of smallpox in adults and children with a weight of at least 13kg, and is the first approved anti-smallpox drug. In 2022, the European Medicines Agency approved it for the treatment of smallpox, monkeypox, vaccinia, and vaccinia complications following smallpox vaccination.

     According to the information published on the website of the Centers for Disease Control and Prevention (CDC), Tecovirimat has been used in the off-label (compassionate use) form to treat patients infected with monkeypox virus since the outbreak of monkeypox disease in 2022, and has a positive effect on reducing the amount of virus in the body.

     On September 15, 2023, the National Health Commission announced that according to the relevant provisions of the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases, monkeypox would be included in Category B infectious diseases from September 20, 2023, and the prevention and control measures of Category B infectious diseases would be taken accordingly. The Monkeypox Prevention and Control Plan formulated and issued by the National Disease Control and Administration Center and the National Health Commission still focuses on prevention, and there is no mention of effective antiviral treatment plan.

     Brincidofovir (also known as CMX001) is an orally active lipophilic form of cidofovir (CDV), a prodrug of cidofovir that is designed to release cidofovir within cells. It has stronger in vivo and in vitro activity than CDV against certain herpes viruses, adenoviruses and orthopoxviruses, and is an antiviral drug used to treat cytomegalovirus, adenovirus, smallpox and Ebola virus infections. It is indicated for the treatment of human smallpox disease caused by smallpox virus in adult and child patients, including newborns. On June 04, 2021, the U.S. Food and Drug Administration approved Brincidofovir tablets and oral suspension for the treatment of smallpox.
