A clinical trial to evaluate the antiviral drug tecovirimat, also known as TPOXX, in adults and children with monkeypox has begun in the Democratic Republic of the Congo (DRC). The trial will evaluate the drug’s safety and its ability to mitigate monkeypox symptoms and prevent serious outcomes, including death. The National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health, and the DRC’s National Institute for Biomedical Research (INRB) are co-leading the trial as part of the government-to-government PALM partnership. Collaborating institutions include the U.S. Centers for Disease Control and Prevention (CDC), the Institute of Tropical Medicine Antwerp, the aid organization Alliance for International Medical Action (ALIMA) and the World Health Organization (WHO).
TPOXX, made by the pharmaceutical company SIGA Technologies, Inc. (New York), is approved by the U.S. Food and Drug Administration for the treatment of smallpox. The drug impedes the spread of virus in the body by preventing virus particles from exiting human cells. The drug targets a protein that is found on both the virus that causes smallpox and the monkeypox virus.
