Novavax新冠疫苗寄予厚望,后起之秀疟疾疫苗迎来里程碑

2021-04-28 JACKZHAO MedSci原创

戴琪与制药商Novavax一名高管进行了线上会议,讨论增加新冠疫苗产量事宜。

4月27日,美国贸易代表戴琪办公室周二声明表示,戴琪与制药商Novavax高层进行了线上会议,讨论增加新冠疫苗产量事宜。在美国总统拜登称,美国计划与需要援助的国家共享COVID-19疫苗后,拜登说道:“问题是现在,我们必须确保我们还有其他疫苗,例如Novavax和其他可能正在出现的疫苗。政府正在讨论正在决定何时将COVID-19疫苗分发到包括印度在内的其他国家,近来,印度一直在与新冠病例激增作斗争。

同日,韩国总统文在寅会见了总部位于马里兰州的Novavax的首席执行官,并承诺将推动该公司新冠疫苗的迅速批准,该疫苗将通过一家当地生物技术公司生产。韩国官员希望,随着美国,欧洲国家和印度在应对国内疫情爆发的同时加强对疫苗出口的控制,SK Bioscience生产的Novavax疫苗将有助于防止未来几个月可能出现的供应短缺。

据悉,SK Bioscience公司今年已与Novavax签订了生产4000万剂疫苗的合同,生产可能会在6月开始,到9月将有多达2000万剂交付韩国使用。 SK已经在其南部城镇安东的工厂生产由阿斯利康研发的疫苗。

自2020年初以来,由于Novavax致力于开发新冠疫苗,因此受到了广泛关注。NVX-CoV2373是基于基因序列设计,利用Novavax的重组纳米粒子技术创建的纳米颗粒疫苗,可产生源自冠状病毒刺突(S)蛋白的抗原,并包含Novavax的专利皂甙型Matrix-M™佐剂,可增强免疫反应并刺激高水平的中和抗体。其临床试验数据表明,该生物技术公司的新冠候选疫苗NVX-CoV2373似乎很有希望。

今年1月初,Novavax研发的新冠病毒疫苗(NVx-CoV2373)在英国进行三期临床试验中期分析结果显示,其在保护人们免受新冠病毒感染方面的有效性为89.3%,并且发生严重和医疗不良事件的发生率较低。

而且它似乎也能(尽管效果不佳)针对在该国和南非流行的新突变病毒。他们认为该疫苗对较旧的新冠病毒有近96%的有效率,而对新变种有近86%的有效率。该消息发布之际,人们担心在世界各地推出的各种疫苗是否足够强大,足以抵御令人担忧的新变种,并且世界迫切需要新型疫苗来增加稀缺的疫苗供应。

对英国15000人的研究仍在进行中。到目前为止,已有62名参与者被诊断新冠肺炎只有六名参与者接受了疫苗,其余的参与者接受了安慰剂注射。

然而, Novavax在南非进行的另一项2b期临床试验中期结果显示,该疫苗的确有效,但效果却不及针对英国的这种疫苗。南非的研究包括一些艾滋病毒志愿者。在艾滋病毒阴性的志愿者中,这种疫苗似乎有效率为60%。若包括艾滋病毒志愿者在内,总体上该疫苗有效率仅为49.4%。到目前为止,在南非研究中发现的90%的新冠病例是由于新变异毒株引起的。

南非负责该疫苗研究负责人约翰内斯堡威特沃特斯兰德大学的Shabir Madhi说,该研究显示另一个完全不同的问题更加令人担忧,这是人们第二次获得COVID-19的机会。测试表明,将近三分之一的研究参与者以前曾被感染,但安慰剂组中的新感染率相似。他说道:“在南非过去感染并不能防止这种变异病毒感染,似乎没有得到任何保护。”

对于南非试验结果较低的有效性,Novavax表示,将对疫苗进行改良,以更好地针对在南非流行的变异毒株,并计划在第二季度开始试验。

各治疗组的抗IgG棘突蛋白反应水平,C. Keech, et al. Phase 1–2 Trial of a SARS-CoV-2 Recombinant Spike Protein Nanoparticle Vaccine. The New England Journal of Medicine. September 2,2020. DOI: 10.1056/NEJMoa2026920

去年9月发表在《新英格兰医学》结果显示,在使用佐剂的情况下,剂量为5µg的NVX CoV2373与剂量为25µg的NVX CoV2373引发的中和抗体平均几何滴度(GMT)相当,峰值均大于3300,可见其诱导的中和反应即可超过大多数有症状的新冠肺炎康复患者血清中的反应水平。在35天时,从已有数据上看,NVX-CoV2373是安全的,而且其引起的免疫反应超过了新冠患者恢复期的血清水平。Matrix-M1佐剂诱导的CD4+T细胞应答偏向Th1表型。

美国政府此前与Novavax签署了一项16亿美元的协议,以资助其新冠疫苗的后期开发和生产,并规定如果该药在临床试验中获得成功,则Novavax将提供1亿剂疫苗。 Novavax还与澳大利亚,加拿大,英国和印度签署了供应协议。

印度血清研究所(SII)去年也表示,它将从Novavax获得授权以生产COVID-19疫苗。SII指出,将在使用来自Gavi、疫苗联盟和比尔及梅琳达·盖茨基金会的资金,为印度和中低收入国家生产多达1亿剂疫苗。

Novavax最近因其在另一款疟疾疫苗的临床研究中宣布的出色结果而成为关注的焦点。

4月23日,牛津大学Mehreen研究团队在《柳叶刀》杂志在预印本上在线发表了评估疟疾候选疫苗R21的2b期临床试验的结果。结果显示该疫苗的有效率为77%。

该研究招募了来自名为Nanoro的地区的450名参与者,季节性疟疾传播率很高。在三个研究小组中,年龄在5至17个月的参与者接受了5mg R21、25mg或50mg Matrix-M佐剂或狂犬病疫苗(对照)。参与者每四周间隔接受三剂,一年后接受最后一剂第四剂。对该疫苗的安全性,免疫原性和功效进行了一年以上的评估。

研究人员在文章写道,在较高的辅助剂量组中,六个月的疫苗效力为77%,在较低的辅助剂量组中为71%。一年后,高辅助剂量组的疗效保持在77%。这大大高于迄今为止最有效的疟疾疫苗候选者RTS,S / AS01疫苗,在非洲儿童中,该疫苗在12个月内的有效率为55.8%。

从2b阶段的结果来看,Matrix-M似乎可以帮助提高功效非常明显。在这项研究中,给17个月至5岁的儿童服用5毫克R21和25毫克或50毫克的Matrix-M。较低的Matrix-M剂量可达到71%的功效,而较高的剂量则可达到77%的功效。

据报道,两种佐剂的剂量水平都耐受良好,没有严重的反应。此外,接种R21 / Matrix-M的参与者在第三次接种后28天显示出高滴度的疟疾特异性抗NANP抗体,在较高的辅助剂量下几乎翻了一番。尽管抗体滴度会随着时间的流逝而减弱,但是在一年后的第四次给药后,抗体的滴度提高到了与初次接种一系列疫苗后达到的峰值滴度相似的水平。

Lakshmi Mittal和Adrian Hill表示:“这些重大成果支持了我们对这种疫苗潜力的高度期望,其中包括达到世卫规定的具有至少75%功效的疟疾疫苗的目标。疫苗学牛津大学詹纳研究所所长;牛津马丁疫苗计划联合主任,也是该文章合著者。 “在我们的商业伙伴印度血清研究所的承诺下,在未来几年中,每年将至少生产2亿剂疫苗,我们相信这种疫苗可能会对公众健康产生重大影响。

根据许可协议,疟疾疫苗的Matrix-M成分将由Novavax制造并提供给SII,后者有权在该病流行的地区在疫苗中使用Matrix-M,并将向市场上的Novavax支付特许权使用费疫苗的销售。此外,Novavax将拥有在某些国家(主要是在旅行者和军用疫苗市场)销售和分销SII制造的疫苗的商业权利。

R21由牛津大学开发,该大学还参与研发了阿斯利康销售的COVID-19疫苗。R21是通过在多形汉逊酵母中表达重组HBsAg病毒样颗粒而产生的,该颗粒包含与HBsAg10 N端融合的环子孢子蛋白(CSP)的中央重复和C端,由印度血清研究所私人有限公司制造 (SIIPL)。 Novavax公司的Matrix-M佐剂用于增强疟疾疫苗的免疫反应。 Matrix-M还与Novavax的COVID-19候选疫苗及其流感疫苗NanoFlu一起使用。

2019年,全世界估计有2.29亿疟疾病例,估计有409,000例死亡。 5岁以下的儿童是最脆弱的群体,占2019年全球死亡的67%。该疫苗的3期试验已开始在四个疟疾传播率和非洲季节性不同的国家的5个试验地点进行募集,以研究大型疟疾。规模的安全性和有效性。

2019年,全球约有2.29亿疟疾病例,估计有409,000例死亡。 5岁以下的儿童约占死亡人数的三分之二。尽管葛兰素史克公司目前销售疟疾疫苗,但其功效仅在35%至55%之间。如果R21最终获得批准,那将是预防疟疾的真正里程碑。

R21是疫苗的改良形式,目前已在一项正在进行的研究中部署,该研究已在马拉维,肯尼亚和加纳的数十万儿童中使用。该疫苗称为RTS,S或Mosquirix,在一年内有效约56%,在四年内有效36%。

加纳大学阿克拉分校的流行病学专家夸瓦德·科拉姆(Kwadwo Koram)说,R21的设计目的是比Mosquirix更有效,更便宜。但是,在更大的研究中对这种疫苗进行试验时,这项在布基纳法索的纳诺罗完成的试验是否有希望的结果能否持久,还有待观察。

研究的主要作者,纳米罗市健康科学研究所的寄生虫学家哈利杜·廷托说,研究人员计划在一项针对4,800名儿童的大型试验中测试R21。R21的目前成绩令人鼓舞,如果与其他预防措施(例如有效的蚊子控制)结合使用,即使效力低于75%的疫苗也可以帮助减少死亡。

预计该公司将在今年第二季度报告其在美国和墨西哥正在进行的大型后期新冠疫苗研究的数据,截至上周五收盘,该股迄今已上涨133.2%。周二,Novavax Inc. NVAX上涨16.33%,至257.67美元,涨幅为16.33%。
