Merck收购OncoImmune

新泽西州凯尼沃思 & 马里兰州罗克威尔 -默克公司(Merck,在美国与加拿大以外称MSD)与临床阶段的私营生物制药公司OncoImmune今日宣布,双方已达成最终协议:默克将通过一家子公司以4.25亿美元现金收购OncoImmune全部流通股。此外,OncoImmune的股东未来还可获得基于销售额的里程碑付款以及监管里程碑付款。OncoImmune近期公布了其首个候选药物CD24Fc治疗重度及危重型COVID-19III期研究中期积极结果。 

全球可能有数百万患者将发展为重度或危重型COVID-19,他们亟需有显著疗效的新治疗方式,“默克研究实验室总裁Roger M. Perlmutter博士表示,“最新临床研究支持CD24Fc在标准治疗基础上,为需要吸氧支持的COVID-19患者带来额外获益,因此它将成为默克抗击新冠疫情在研药物和疫苗管线的重要补充。” 

OncoImmune公布的203名受试者(占计划入组人数75%)中期分析显示,接受单剂CD24Fc治疗的重度/危重型COVID-19患者,按临床试验方案定义的临床改善概率较安慰剂组提高60%,而死亡或呼吸衰竭风险降低逾50%。详细结果将投稿同行评审医学期刊。 

“OncoImmune团队在III期试验中为CD24Fc用于重度及危重型COVID-19患者提供了有力证据,”OncoImmune联合创始人兼首席执行官刘阳博士表示,“我们期待与默克的科学家制造团队以及监管机构合作,加速这一潜在重要疗法的全球开发。” 

根据协议,在收购完成前,OncoImmune将把与CD24Fc项目无关的部分权利和资产剥离给一家由现有股东持有的新公司;交易交割时,默克将向该新公司投资5000万美元并成为股东。本次收购需获《哈特-斯科特-罗迪诺反垄断改进法》批准并满足其他惯例交割条件,预计2020年底前完成。OncoImmune的法律顾问为Goodwin Procter LLP,财务顾问为Guggenheim Securities。 

关于SAC-COVID 3期临床试验 

SAC-COVID 3期临床试验(NCT04317040)是一项随机,双盲,安慰剂对照试验,旨在评估CD24Fc治疗住院的、需要氧气支持(含普通氧疗、高流量氧疗及机械通气)的住院COVID-19患者的安全性和有效性。受试者被随机分为两组,治疗组在第1天接受标准治疗并通过静脉输注单剂量CD24Fc,安慰剂组在第1天接受标准治疗加安慰剂。这项多中心的3期临床试验于20204月开始,已有243名患者入组,并于20209月停止招募。
