While effective, the smallpox vaccine is currently not recommended for routine use in the general public due to safety concerns (\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"http:\/\/www.bt.cdc.gov\/agent\/smallpox\/vaccination\">http:\/\/www.bt.cdc.gov\/agent\/smallpox\/vaccination<\/jats:ext-link>\n                    ). Safe and effective countermeasures, particularly those effective after exposure to smallpox, are needed. Currently, SIGA Technologies is developing the small-molecule oral drug, tecovirimat (previously known as ST-246), as a postexposure therapeutic treatment of orthopoxvirus disease, including smallpox. Tecovirimat has been shown to be efficacious in preventing lethal orthopoxviral disease in numerous animal models (G. Yang, D. C. Pevear, M. H. Davies, M. S. Collett, T. Bailey, et al., J. Virol.\n                    <jats:bold>79:<\/jats:bold>\n                    13139\u201313149, 2005; D. C. Quenelle, R. M. Buller, S. Parker, K. A. Keith, D. E. Hruby, et al., Antimicrob.

Furthermore, in clinical trials thus far, the drug appears to be safe, with a good pharmacokinetic profile. In this study, the efficacy of tecovirimat was evaluated in both a prelesional and postlesional setting in nonhuman primates challenged intravenously with 1 \u00d7 10\n                    <jats:sup>8<\/jats:sup>\n                    PFU of\n                    <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">Variola virus<\/jats:named-content>\n                    (VARV; the causative agent of smallpox), a model for smallpox disease in humans. Following challenge, 50% of placebo-treated controls succumbed to infection, while all tecovirimat-treated animals survived regardless of whether treatment was started at 2 or 4 days postinfection. In addition, tecovirimat treatment resulted in dramatic reductions in dermal lesion counts, oropharyngeal virus shedding, and viral DNA circulating in the blood. Although clinical disease was evident in tecovirimat-treated animals, it was generally very mild and appeared to resolve earlier than in placebo-treated controls that survived infection. Tecovirimat appears to be an effective smallpox therapeutic in nonhuman primates, suggesting that it is reasonably likely to provide therapeutic benefit in smallpox-infected humans.\n                  <\/jats:p>","DOI":"10.1128\/aac.00977-13","type":"journal-article","created":{"date-parts":[[2013,10,7]],"date-time":"2013-10-07T23:08:58Z","timestamp":1381187338000},"page":"6246-6253","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":89,"title":["Efficacy of Tecovirimat (ST-246) in Nonhuman Primates Infected with Variola Virus (Smallpox)"],"prefix":"10.1128","volume":"57","author":[{"given":"Eric M.","family":"Mucker","sequence":"first","affiliation":[{"name":"United States Army Medical Research Institute of Infectious Diseases (USAMRIID), Fort Detrick, Frederick, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arthur J.","family":"Goff","sequence":"additional","affiliation":[{"name":"United States Army Medical Research Institute of Infectious Diseases (USAMRIID), Fort Detrick, Frederick, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua D.","family":"Shamblin","sequence":"additional","affiliation":[{"name":"United States Army Medical Research Institute of Infectious Diseases (USAMRIID), Fort Detrick, Frederick, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Douglas W.","family":"Grosenbach","sequence":"additional","affiliation":[{"name":"SIGA Technologies, Inc., Corvallis, Oregon, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inger K.","family":"Damon","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason M.","family":"Mehal","sequence":"additional","affiliation":[{"name":"Division of High-Consequence Pathogens and Pathology, CDC, Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert C.","family":"Holman","sequence":"additional","affiliation":[{"name":"Division of High-Consequence Pathogens and Pathology, CDC, Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darin","family":"Carroll","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadia","family":"Gallardo","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria A.","family":"Olson","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cody J.","family":"Clemmons","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Hudson","sequence":"additional","affiliation":[{"name":"Poxvirus and Rabies Branch, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis E.","family":"Hruby","sequence":"additional","affiliation":[{"name":"SIGA Technologies, Inc., Corvallis, Oregon, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-127-8_Part_1-199710150-00010"},{"key":"e_1_3_3_3_2","volume-title":"Smallpox and its eradication","author":"Fenner F","year":"1988","unstructured":"FennerF HendersonDA AritaI JezekZ LadnyiID. 1988.
