瑞士巴塞爾2019年3月5日電 /美通社/ -- 2019年3月4日，諾華公布了一項(xiàng)有關(guān)中國(guó)患者使用司庫(kù)奇尤單抗（俗稱“蘇金單抗”）治療中至重度斑塊狀銀屑病有效性及安全性的最新III期研究數(shù)據(jù)。該III期研究是一項(xiàng)隨機(jī)、雙盲、安慰劑對(duì)照、國(guó)際多中心研究，為期52周，入組患者543名。此次公布的是該研究中針對(duì)441位中國(guó)患者的數(shù)據(jù)。
數(shù)據(jù)顯示，在所有接受司庫(kù)奇尤單抗300毫克治療的中國(guó)患者中，分別有97.7％和80.9％的患者在第12周達(dá)到了PASI 75（即銀屑病面積和嚴(yán)重性指數(shù)改善75%）和PASI 90，87％的患者在第16周達(dá)到PASI 90[1]。
“這次中國(guó)臨床試驗(yàn)的數(shù)據(jù)非常喜人，在療效和安全性方面甚至優(yōu)于一些國(guó)際數(shù)據(jù)。”中華醫(yī)學(xué)會(huì)皮膚性病學(xué)分會(huì)前任主任委員張建中教授作為此次III期研究項(xiàng)目負(fù)責(zé)人表示：“這一結(jié)果或?qū)橹袊?guó)銀屑病治療帶來(lái)革命性變化，將推動(dòng)中國(guó)銀屑病治療策略的整體轉(zhuǎn)變。首先，它有助于整體治療目標(biāo)的提升，有望將銀屑病治療目標(biāo)從PASI 75提高到PASI 90甚至PASI 100；其次，這次III期研究體現(xiàn)了司庫(kù)奇尤單抗很好的安全性。過(guò)去生物制劑僅在光療及系統(tǒng)性治療無(wú)效后才被考慮使用，但未來(lái)這個(gè)順序很可能被改寫，生物制劑有可能成為系統(tǒng)治療的一線藥物，這樣可使更多中重度銀屑病患者及早獲得更好更安全的治療。”
“諾華始終致力于幫助銀屑病患者實(shí)現(xiàn)心中所愿 -- 創(chuàng)想醫(yī)藥，帶來(lái)可實(shí)現(xiàn)皮損清除及全面獲益的治療方式，”諾華免疫學(xué)、肝病和皮膚病學(xué)全球開發(fā)部門負(fù)責(zé)人、中國(guó)地區(qū)開發(fā)負(fù)責(zé)人Eric Hughes先生表示，“我們很高興能首次發(fā)布有關(guān)中國(guó)患者的喜人數(shù)據(jù)，并看到這些數(shù)據(jù)為司庫(kù)奇尤單抗在銀屑病治療的獨(dú)特優(yōu)勢(shì)地位提供有力印證。”
全球100項(xiàng)臨床研究中積累的大量數(shù)據(jù)證明了在每10位患者中有8位可通過(guò)16周司庫(kù)奇尤單抗治療實(shí)現(xiàn)皮損清除或幾乎清除[3]。患者應(yīng)答率可近100%維持長(zhǎng)達(dá)5年[4]。它是一種中和IL-17A的全人源單克隆抗體，在中至重度銀屑病、關(guān)節(jié)型銀屑病以及其它部位銀屑病（頭皮、掌跖和指（趾）甲銀屑病）的治療中體現(xiàn)出快速、持久的療效及安全性[5,6]。

關(guān)于司庫(kù)奇尤單抗
司庫(kù)奇尤單抗是目前首個(gè)也是唯一一個(gè)能特異性抑制白細(xì)胞介素17A（IL-17A）的全人源化生物制劑。IL-17A是參與銀屑病（PsO）、關(guān)節(jié)病型銀屑病（PsA）和強(qiáng)直性脊柱炎（AS）炎癥產(chǎn)生及疾病進(jìn)展的核心致病因子，在發(fā)病機(jī)制中起基石作用[7-10]。IL-17A可以由IL-23依賴性和IL-23非依賴性兩種途徑產(chǎn)生，由先天免疫系統(tǒng)（可由機(jī)械應(yīng)激觸發(fā)）和適應(yīng)性免疫系統(tǒng)的多種細(xì)胞產(chǎn)生[11]。通過(guò)直接作用于不同來(lái)源的IL-17A，司庫(kù)奇尤單抗可抑制這一起基石作用的細(xì)胞因子[8]。
作為一個(gè)成熟產(chǎn)品，司庫(kù)奇尤單抗擁有三大適應(yīng)癥（PsO、PsA、AS）以及超過(guò)200,000名患者5年持續(xù)性療效和安全性數(shù)據(jù)支持[2,6,12,13]。司庫(kù)奇尤單抗擁有快速長(zhǎng)期的療效以及高度穩(wěn)定的良好安全性，幾乎無(wú)注射部位反應(yīng)或疼痛[6,12,14-17]。目前已在包括歐盟國(guó)家和美國(guó)在內(nèi)的80多個(gè)國(guó)家和地區(qū)批準(zhǔn)上市，擁有100項(xiàng)真實(shí)世界和臨床研究支持[2,18]。
