       9月1日,在新加坡召開的OPTIONS X 2019會(huì)議上,羅氏集團(tuán)第一時(shí)間展示了在研流感藥物Xofluza(baloxavir marboxil)兩項(xiàng)III期臨床試驗(yàn)的積極數(shù)據(jù)。羅氏引領(lǐng)全球抗擊流感的前沿,快隨我們一探究竟!

       Xofluza使接觸感染者后患上流感的風(fēng)險(xiǎn)降低86%

       · BLOCKSTONE研究達(dá)到主要終點(diǎn),與安慰組相比,使用Xofluza的人群更少被檢驗(yàn)出流感,或出現(xiàn)發(fā)燒或至少一種呼吸道癥狀。

       · 無論對(duì)減少普通季節(jié)性流感,或是限制大規(guī)模流感爆發(fā),Xofluza都有望成為便捷、有效的治療方法。

       III期BLOCKSTONE研究表明,在接觸感染流感的家庭成員后,使用Xofluza進(jìn)行預(yù)防治療,相較于安慰劑,可使患上流感的風(fēng)險(xiǎn)顯著降低86%。研究結(jié)果表明,使用Xofluza治療的家庭成員只有1.9%患上流感,而安慰劑治療組的比例為13.6%(p<0.0001)。而且,在不同亞型的甲型流感中,相比于安慰劑,Xofluza均表現(xiàn)出統(tǒng)計(jì)學(xué)上的顯著獲益(H1N1: 1.1% vs 10.6%,p=0.0023;H3: 2.8% vs. 17.5%,p<0.0001)。此外,在流感感染高風(fēng)險(xiǎn)人群(2.2% vs 15.4%,p=0.0435)及更容易患上流感的未滿12周歲(4.2% vs 15.5%,p=0.0339)的兒童接觸中也觀察到這種差異。Xofluza相較于安慰劑表現(xiàn)出可比的安全性,Xofluza的不良事件總體發(fā)生率為22.2%,而安慰劑為20.5%。沒有嚴(yán)重不良事件報(bào)告。

       單劑量Xofluza在兒童流感患者中取得陽性結(jié)果

       · III期MINISTONE-2數(shù)據(jù)顯示,Xofluza在兒童中的安全性與已知的安全性特征一致,且療效與奧司他韋可比。

       · 作為新的單劑口服混懸液給藥,Xofluza是一種潛在的對(duì)兒童更加方便的治療選擇。

       · 兒童患流感的風(fēng)險(xiǎn)高,每年流感并發(fā)癥導(dǎo)致全球?qū)⒔?00萬5歲以下的兒童住院。

       III期MINISTONE-2研究表明,單劑量Xofluza對(duì)未滿12周歲既往健康的兒童流感患者,是一種耐受性良好、有效的潛在流感治療手段。該研究評(píng)估了截至研究第29天出現(xiàn)不良事件(AEs)或嚴(yán)重不良事件的患者比例,結(jié)果表明與Xofluza的已知安全性一致,達(dá)到主要終點(diǎn)。在接受Xofluza治療的參與者中,有46.1%經(jīng)歷至少一次治療引發(fā)的不良事件,而奧司他韋組為53.4%。研究還表明,Xofluza的療效與奧司他韋(一種證實(shí)有效的兒童流感治療方案)可比 。此外,與成人和青少年群體的數(shù)據(jù)一致,與奧司他韋相比,Xofluza使流感病毒從體內(nèi)排出的時(shí)間縮短了兩天多 (病毒排毒中位時(shí)間分別為24.2小時(shí)與75.8小時(shí))。
