恩司特韋^[1]（代號：S-217622，商品名：Xocova）^[2]是鹽野義製藥公司與北海道大學合作開發的一種抗病毒藥物，可作為口服活性3C樣蛋白酶抑制劑，用於治療COVID-19感染。^[3]^[4]它是口服的，並且已經成功地針對最近出現的奧米克戎變體進行了測試。^[5]^[6]

歷史[編輯]

它已進入III期臨床試驗。^[7]據報道，日本政府正在考慮允許鹽野木在最後的試驗步驟完成之前申請醫療用途的批准，這可能會加快上市銷售。這種有條件的早期批准系統此前已在日本用於加速其他針對 COVID-19的抗病毒藥物的上市進程，包括瑞德西韋和莫努匹韋。^[8]在一項針對428名患者的研究中，病毒載量降低，但症狀並未顯着減輕。^[9]

如果獲得批准，它將成為第一個治療COVID-19的日本國產藥丸，也是第三個在日本獲得批准的藥丸。2022年2月，該公司向日本監管機構尋求緊急批准。^[9]

鹽野義製藥公司宣布，他們已達成初步協議，一旦該藥物獲得批准，將向日本政府供應100萬劑。這位首席執行官表示，他們有能力每年生產1000萬劑。^[10]
