本期看點(diǎn):
1. 賽諾菲(Sanofi)公布,其在研呼吸系統(tǒng)療法lunsekimig在兩項(xiàng)2期臨床試驗(yàn)中均達(dá)到主要終點(diǎn)及關(guān)鍵次要終點(diǎn),分別在中重度哮喘和慢性鼻竇炎伴鼻息肉(CRSwNP)患者中展現(xiàn)出積極療效。
2. Praxis Precision Medicines宣布,其反義寡核苷酸(ASO)療法elsunersen在針對早發(fā)性癲癇型SCN2A發(fā)育性與癲癇性腦病(SCN2A-DEE)兒童患者開展的1/2期臨床試驗(yàn)中取得積極結(jié)果。治療使患者癲癇發(fā)作頻率較基線降低77%。

Lunsekimig:2期試驗(yàn)結(jié)果公布
賽諾菲日前公布其在研呼吸系統(tǒng)療法lunsekimig的2期臨床研究結(jié)果。該藥物是一種新型雙特異性納米抗體,由五個連接的抗體片段構(gòu)成,旨在同時阻斷胸腺基質(zhì)淋巴細(xì)胞生成素(TSLP)和白細(xì)胞介素-13(IL-13)兩條炎癥信號通路,這兩種通路被認(rèn)為是哮喘及相關(guān)疾病中導(dǎo)致組織損傷的重要炎癥驅(qū)動因素。研究結(jié)果顯示,在兩項(xiàng)針對慢性呼吸系統(tǒng)疾病的2期研究中,lunsekimig均達(dá)到主要終點(diǎn)及關(guān)鍵次要終點(diǎn),相比安慰劑顯示出明確療效。同時,在所有研究中該藥物整體耐受性良好,安全性特征可接受。

具體來看,在AIRCULES 2b期研究中,lunsekimig在中重度哮喘患者中達(dá)到主要終點(diǎn)和關(guān)鍵次要終點(diǎn),無論患者的生物標(biāo)志物狀態(tài)如何均顯示療效。研究結(jié)果表明,與安慰劑相比,該療法可在統(tǒng)計(jì)學(xué)和臨床意義上顯著減少疾病急性加重,并改善肺功能指標(biāo)——支氣管擴(kuò)張劑使用前的一秒用力呼氣容積(pre-BD FEV1)。此外,在DUET 2a期概念驗(yàn)證研究中,lunsekimig在慢性鼻竇炎伴鼻息肉患者中同樣達(dá)到主要終點(diǎn)及關(guān)鍵次要終點(diǎn),在第24周時與安慰劑相比顯著改善鼻息肉評分、患者報(bào)告的鼻塞/阻塞評分以及Lund-Mackay計(jì)算機(jī)斷層掃描評分。
Elsunersen:公布1/2期臨床試驗(yàn)數(shù)據(jù)
Praxis Precision Medicines近日宣布,其在研療法elsunersen在EMBRAVE臨床1/2期試驗(yàn)A部分中取得積極結(jié)果。該研究在早發(fā)性癲癇型SCN2A發(fā)育性與癲癇性腦病兒童患者中開展。Elsunersen是一種ASO療法,旨在選擇性降低SCN2A基因表達(dá),從而直接靶向早發(fā)性癲癇型SCN2A-DEE的致病機(jī)制,用于治療攜帶SCN2A功能獲得性突變患者的癲癇發(fā)作及其他相關(guān)癥狀。

研究結(jié)果顯示,在療效方面,與安慰劑相比,elsunersen治療使患者癲癇發(fā)作頻率較基線降低77%(p=0.015,95% CI:33–92)。同時,57%的患者實(shí)現(xiàn)了至少連續(xù)28天無癲癇發(fā)作。療效在開放標(biāo)簽延長期(OLE)中可持續(xù)長達(dá)一年。此外,與安慰劑組未觀察到改善相比,所有接受elsunersen治療的患者在睡眠、運(yùn)動功能、肌張力、注意力或神經(jīng)精神運(yùn)動發(fā)育等指標(biāo)上均出現(xiàn)改善。在安全性方面,elsunersen整體耐受性良好。
Muzastotug:公布1/2期臨床試驗(yàn)數(shù)據(jù)
日前,天演藥業(yè)公布其在研藥物 掩蔽型抗CTLA-4 SAFEbody安全抗體 muzastotug治療無肝轉(zhuǎn)移MSS CRC(晚期微衛(wèi)星穩(wěn)定型結(jié)直腸癌)1b/2期臨床研究的最新數(shù)據(jù)。 截至2026年1月24日的最新數(shù)據(jù)截點(diǎn),共有67例無肝轉(zhuǎn)移的MSS CRC患者(包括腹膜轉(zhuǎn)移亞群)接受了muzastotug(10 mg/kg或20 mg/kg)聯(lián)合帕博利珠單抗治療。

在該研究劑量擴(kuò)展階段的65例可評估患者中,10 mg/kg劑量組(N=39)的中位無進(jìn)展生存期(mPFS)為4.8個月,20 mg/kg劑量組(N=26)mPFS為6.7個月。值得注意的是,在接受誘導(dǎo)/維持給藥方案(20 mg/kg單次負(fù)荷劑量 + 10 mg/kg每3周一次)的14例患者中,mPFS顯著延長至15.4個月,而未采用該策略的12例20 mg/kg每6周一次(Q6W)給藥患者中,mPFS為4.9個月。這一差異進(jìn)一步印證了誘導(dǎo)/維持方案的重要性,目前該方案正于正在進(jìn)行的隨機(jī)2期試驗(yàn)中接受評估。此外,10 mg/kg劑量組的中位總生存期(OS)達(dá)到19.8個月(中位隨訪時間23.8個月)。20 mg/kg劑量組的中位OS尚未達(dá)到(中位隨訪13.1個月)。20 mg/kg劑量組患者的1年OS率為80.8%,而10 mg/kg劑量組患者在12個月時的OS率為70.1%,24個月時為48%。
