協(xié)和麒麟宣布,惠爾金?(莫格利珠單抗)已獲國家藥品監(jiān)督管理局(NMPA)的正式批準(zhǔn),用于治療既往接受過系統(tǒng)性治療的復(fù)發(fā)或難治性塞扎里綜合征(SS)或晚期(III/IV)蕈樣肉芽腫(MF)成人患者。

       協(xié)和麒麟宣布,惠爾金®(莫格利珠單抗)已獲國家藥品監(jiān)督管理局(NMPA)的正式批準(zhǔn),用于治療既往接受過系統(tǒng)性治療的復(fù)發(fā)或難治性塞扎里綜合征(SS)或晚期(III/IV)蕈樣肉芽腫(MF)成人患者[2]。惠爾金®是中國首 個也是唯一獲批用于治療SS和MF的靶向CCR4的生物制劑[1]。莫格利珠單抗是一款同類首 創(chuàng)的人源化單克隆抗體(mAb),靶向C-C趨化因子受體4(CCR4)[3],后者是在SS和MF癌癥細(xì)胞上存在持續(xù)表達(dá)的一種蛋白質(zhì)[4],[5],[6]。一旦惠爾金®與CCR4相結(jié)合,會在人體免疫系統(tǒng)中激活更多的免疫細(xì)胞,進(jìn)而破壞癌細(xì)胞[7]。

       皮膚T細(xì)胞淋巴瘤(CTCL)屬于罕見型非霍奇金淋巴瘤,SS和MF是CTCL的最常見的兩種亞型[8],可累及患者皮膚、血液、淋巴結(jié)和內(nèi)臟器官[9]。CTCL較罕見,每10萬人中約有24名患者[10]。歐洲MF的年發(fā)病率約為1/11萬~1/35萬[11],而SS的年發(fā)病率為1/1000萬[12]。這兩種亞型加起來約占所有CTCL病例的65%[9]?;颊咂毡樯钯|(zhì)量差、誤診率高且晚期缺乏靶向治療藥物,通常會出現(xiàn)皮損、發(fā)癢、疼痛以及不可預(yù)知的皮膚癥狀,并可能會導(dǎo)致進(jìn)一步的并發(fā)癥,從而影響他們的預(yù)期壽命[3],[13]。由于CTCL與濕疹及牛皮癬等常見皮膚病相似[14],患者平均需要2-7年才能得到確診[15]。晚期患者的預(yù)后明顯更差,約半數(shù)患者(52%)的生存期僅為5年[16]。

       協(xié)和麒麟中國總經(jīng)理李韻表示:"惠爾金®于2021年7月獲得藥品審評中心授予的優(yōu)先審評資格,現(xiàn)已獲國家藥品監(jiān)督管理局的正式批準(zhǔn)。我們感謝監(jiān)管機(jī)構(gòu)對莫格利珠單抗的加速批準(zhǔn),這展示了政府為具有高度未被滿足醫(yī)療需求的中國患者帶來創(chuàng)新藥物的決心。這也為中國的塞扎里綜合征和蕈樣肉芽腫患者帶來了希望,他們將能獲得我們這款同類首 創(chuàng)藥物。協(xié)和麒麟通過追求生命科學(xué)和技術(shù)的進(jìn)步來創(chuàng)造新的價值,我們致力于將更多創(chuàng)新性藥物帶入中國,從而造福廣大中國患者。"

       中國醫(yī)學(xué)科學(xué)院腫瘤醫(yī)院石遠(yuǎn)凱教授表示:"塞扎里綜合征和蕈樣肉芽腫給患者的生活質(zhì)量帶來了沉重的負(fù)擔(dān)。莫格利珠單抗的獲批上市,將為中國這類患者帶來一種全新作用機(jī)制的治療選擇。莫格利珠單抗改善了患者癥狀和生活質(zhì)量,患者的皮膚病變和血液學(xué)指標(biāo)對莫格利珠單抗治療呈現(xiàn)出顯著和持久的效果,中位無進(jìn)展生存期顯著延長。"

       此次獲批是基于MAVORIC研究的結(jié)果。該研究是目前針對SS和MF患者最大規(guī)模的臨床試驗(yàn)[3]。研究結(jié)果表明,惠爾金®組患者的疾病控制時間是對照藥物伏立諾他組患者的兩倍多(中位無進(jìn)展生存期:7.7個月 vs 3.1個月)[3]。在處于各疾病階段的MF/SS患者中,惠爾金®的應(yīng)答率均高于伏立諾他*[3]?;轄柦?reg;和伏立諾他組患者的確認(rèn)總緩解率分別為28%和5%(p<0.001)[3]。惠爾金®的總體耐受性良好,安全性可控[2],[17]。

       MAVORIC研究還評估了患者報告的癥狀體驗(yàn)和生活質(zhì)量(QoL)。結(jié)果表明,與接受伏立諾他治療的患者相比,接受惠爾金®的患者在癥狀、情緒、功能和整體生活質(zhì)量方面均得到改善,體現(xiàn)在大部分功能和癥狀領(lǐng)域。總體而言,這些研究結(jié)果表明,與伏立諾他組相比,惠爾金®組患者的疾病及癌癥特異性狀況相關(guān)生活質(zhì)量和總生活質(zhì)量均得到改善,同時生活質(zhì)量快速惡化的風(fēng)險呈具有統(tǒng)計(jì)學(xué)意義的顯著降低[18]。

       關(guān)于惠爾金®(莫格利珠單抗)

       惠爾金®是一款同類首 創(chuàng)人源化單克隆抗體(mAb),旨在與C-C趨化因子受體4(CCR4)相結(jié)合?;轄柦?reg;與CCR4結(jié)合后,會在人體免疫系統(tǒng)中激活更多的免疫細(xì)胞,進(jìn)而破壞癌細(xì)胞[7]?;轄柦?reg;使用協(xié)和麒麟專有的POTELLIGENT®技術(shù),可增強(qiáng)人體對治療的自然免疫反應(yīng),從而提高對癌細(xì)胞的殺傷力。FDA已授予惠爾金®突破性療法和孤兒藥認(rèn)定[19],[20]。此外,惠爾金®還于2016年被歐盟委員會(EC)授予孤兒藥認(rèn)定[21]。惠爾金®是首 個也是唯一在中國和世界其他地區(qū)獲批的靶向CCR4的生物制劑[22]。
