上海2023年6月30日 /美通社/ -- 6月29日,中國國家藥品監(jiān)督管理局(NMPA)藥品審評(píng)中心(CDE)正式授予勃林格殷格翰罕見皮膚病創(chuàng)新靶向生物制劑圣利卓®(通用名:佩索利單抗注射液)用于預(yù)防泛發(fā)性膿皰型銀屑?。℅eneralized Pustular Psoriasis,GPP)發(fā)作新增適應(yīng)癥優(yōu)先審評(píng)審批資格。該擬定新適應(yīng)癥于5月11日全球率先在華遞交上市申請(qǐng),早于歐美日,開創(chuàng)了行業(yè)先河!值得一提的是4月19日該擬定新適應(yīng)癥已被CDE授予突破性療法認(rèn)定。此前圣利卓®在中國已獲批用于治療成人GPP發(fā)作的適應(yīng)癥也曾獲得CDE優(yōu)先審評(píng)審批資格和突破性療法認(rèn)定。
優(yōu)先審評(píng)是國家藥品監(jiān)督管理局藥品審評(píng)中心(CDE)為鼓勵(lì)研究和創(chuàng)制新藥,滿足臨床用藥需求,加快創(chuàng)新藥品審評(píng)速度而設(shè)置。再次被納入優(yōu)先審評(píng)審批將進(jìn)一步推動(dòng)該新適應(yīng)癥在中國獲批的步伐,讓中國的GPP患者能進(jìn)一步從這一創(chuàng)新的產(chǎn)品中獲益。
GPP是一種罕見的、復(fù)發(fā)性或持續(xù)發(fā)作的皮膚疾病[1],[2],據(jù)統(tǒng)計(jì)在中國每100,000人中僅有1~2人患GPP[3],中國約計(jì)2萬名GPP患者。GPP發(fā)作時(shí),患者的皮膚會(huì)變紅,并在身體各區(qū)域爆發(fā)出許多無菌性的膿皰,出現(xiàn)發(fā)熱、寒戰(zhàn)和皮膚疼痛性病變的癥狀,嚴(yán)重時(shí)會(huì)引起器官衰竭和感染性并發(fā)癥,甚至危及生命。GPP發(fā)作時(shí),不僅嚴(yán)重程度無法預(yù)測(cè),其發(fā)作的時(shí)間同樣難以捉摸。該疾病可能隨時(shí)發(fā)作,持續(xù)數(shù)周,并需要數(shù)月才能痊愈,許多患者甚至在兩次GPP發(fā)作之間持續(xù)出現(xiàn)癥狀。疾病發(fā)作的不可預(yù)測(cè)性和嚴(yán)重程度極大地影響了患者的生存質(zhì)量[4],[5],因此患者迫切需要可以有效預(yù)防GPP發(fā)作且安全的療法。
近年來,有研究發(fā)現(xiàn)膿皰型銀屑病與白細(xì)胞介素-36(IL-36)通路相關(guān)。白細(xì)胞介素-36受體是免疫系統(tǒng)內(nèi)的一種信號(hào)通路,可在包括GPP在內(nèi)的許多炎癥性疾病中發(fā)揮作用[4],[6],[7]。圣利卓®是一款新型人源化選擇性抗體,可阻斷白介素-36受體(IL-36R)的激活,從而抑制GPP的炎癥信號(hào)通路。
圣利卓®關(guān)鍵性EFFISAYIL ? 2臨床試驗(yàn)用于評(píng)價(jià)圣利卓®與安慰劑相比在具有GPP病史的患者中預(yù)防GPP發(fā)作的有效性和安全性。今年1月該臨床試驗(yàn)公布概要結(jié)果,已達(dá)到其主要和關(guān)鍵次要終點(diǎn),研究結(jié)果顯示圣利卓®能顯著預(yù)防GPP發(fā)作長(zhǎng)達(dá)48周[8],[9],其安全性數(shù)據(jù)與此前圣利卓®開展的臨床試驗(yàn)數(shù)據(jù)呈現(xiàn)一致性。EFFISAYIL ? 2臨床試驗(yàn)的完整數(shù)據(jù)結(jié)果將于7月初在2023年第25屆世界皮膚病學(xué)大會(huì)上公布。
