GlaxoSmithKline and Vir Biotechnology were hopeful that one of their partnered antibodies would carve out a win after getting the invite to a major NIH study in hospitalized Covid-19 patients. But just like Eli Lilly, the pair’s drug couldn’t hit the mark, and now they’ll be left to take a hard look at the game plan. The NIH has shut down enrollment for GSK and Vir’s antibody VIR-7831 in its late-stage ACTIV-3 trial after the drug showed negligible effect in achieving sustained recovery in hospitalized Covid-19 patients, the partners said Wednesday. In what could be an early shot in the battle against drugmakers that whiff on confirmatory studies to support accelerated approvals, the FDA ordered Bristol Myers Squibb late last year to give up Opdivo’s approval in SCLC. Now, Merck is next on the firing line — are we seeing the FDA buckling down on post-marketing offenders? Merck has withdrawn its marketing approval for PD-(L)1 inhibitor Keytruda in metastatic small cell lung cancer as part of what it describes as an “industry-wide evaluation” by the FDA of drugs that do not meet the post-marketing checkpoints on which their accelerated nods were based, the company said Monday. The global pandemic may have roiled economies, killed hundreds of thousands and throttled entire industries, but the only effect it had on biopharma venture investing was to help turbocharge the field to giddy new heights. Below you’ll find the new top 100 venture investors in the industry, ranked by the number of deals they were publicly involved in, as tracked by DealForma chief Chris Dokomajilar. The numbers master then calculated the estimated amount of money they put into each deal — divvying up the cash by the number of players — to indicate how they managed their syndicates. A little more than a week after BrainStorm acknowledged that regulators at the FDA had informed them that the biotech needed more data before it could expect to gain an approval for its ALS treatment NurOwn — while still touting a “clear signal” of efficacy and not ruling out an application — the agency has decided to clarify the record in a most unusual statement. The FDA statement amounts to a straight slap own, offering a different set of efficacy numbers from the company’s public presentation last November and ruling out any chance of statistical significance. Over the last decade, drugmakers have proven JAK inhibitors can treat a smattering of immune-related diseases ranging from rheumatoid arthritis to Covid-19. Now Eli Lilly has pulled out a new one. Lilly and its biotech partner Incyte announced Wednesday that their JAK inhibitor baricitinib effectively regrew patients’ hair in a Phase III trial for alopecia areata, an autoimmune condition that can cause sudden, severe and patchy hair loss. Lilly didn’t break down the results from the 546-patient trial, but the primary endpoint was improvement on a standard score for alopecia symptoms. CRLs. 483s. CBER, CDER and RWE. For biopharma professionals, these acronyms command attention because of the fundamental role FDA plays in drug development. Now Endpoints is doubling down on regulatory coverage, and launching a weekly report focusing on developments out of White Oak, with analysis and insight into what it all means. Coverage will be led by our new senior editor, Zachary Brennan. He joins Endpoints from POLITICO, where he covered pharma. Prior to that he was the managing editor for Regulatory Focus, a news publication from the Regulatory Affairs Professionals Society. All the pieces needed to trigger a third wave of Covid-19 vaccine supply to start washing over the US fell neatly into place over the weekend. After providing for a brief mime of regulatory judiciousness, the FDA stamped their emergency approval on J&J’s Covid-19 vaccine Saturday, adding to the Biden administration’s plan aimed at ending the pandemic in the near term — at least in the US. The CDC came through on Sunday with its stamp of approval and J&J is reportedly expected to start delivering vaccine sometime in the next few days. Soticlestat made it. Takeda is bringing the drug back into its fold more than four years after first entrusting the team at Ovid with the mid-stage clinical work. For all that — generating what they saw as positive Phase II data in Dravet syndrome and Lennox-Gastaut syndrome — the biotech has been rewarded with $196 million in upfront cash, with another $660 million reserved for regulatory and commercial milestones. Merck spent $425 million to buy out OncoImmune in November, presumably under the belief that they could scale up their drug for severe Covid-19 and get it through the FDA on the strength of a Phase III trial the smaller biotech completed in September. The FDA threw a wrench in those plans. The agency told Merck last week that the 203-person study wasn’t sufficient to show the drug was effective. Now, Bloomberg reports, Merck is preparing an additional Phase III study, one that will push results — and any chance of approval — back to the end of the year. When Michael Shpigelmacher started the project, he knew he’d have to fund it himself. Every other effort of its kind was academic, rejected as too risky by investors. Shpigelmacher, a robotics geek and entrepreneur who had drifted into consulting for pharma, wanted to build the real-life equivalent of technology from the 1960s film “Fantastic Voyage,” the one where a submarine crew is shrunk to “about the size of a microbe” and sent on a mission to repair a scientist’s brain. He scanned the literature, found the lab that was working on the most advanced project — at the Max Planck Institute in Germany, it turned out — and started funding them with money from his and his co-founders’ own accounts, along with some seed cash from friends and family.
葛兰素史克公司和Vir Biotechnology公司在接到NIH一项针对住院Covid-19患者的重大研究的邀请后,希望他们合作的抗体之一能够赢得胜利。但就像礼来一样,这对组合的药物不能击中目标,现在他们将被留在认真看比赛计划。 合作伙伴周三表示,NIH已经停止了GSK和Vir的抗体VIR-7831在其晚期Active-3试验中的注册,因为该药物在实现住院的Covid-19患者的持续康复方面显示出可忽略不计的效果。 去年年底,FDA命令百时美施贵宝放弃Opdivo在SCLC的审批,这可能是对那些利用验证性研究来支持加速审批的制药商的一次早期打击。现在,默克是下一个上火线的--我们看到FDA对上市后违法者的严厉打击了吗? 默克公司周一表示,该公司已经撤回了对转移性小细胞肺癌的PD-(L)1抑制剂Keytruda的上市批准,作为FDA对不符合上市后检查点的药物进行“全行业评估”的一部分。 这场全球大流行可能扰乱了经济,夺走了数十万人的生命,扼杀了整个行业,但它对生物制药风险投资的唯一影响是帮助该领域达到令人眩晕的新高度。 根据DealForma首席执行官Chris Dokomajilar的记录,以下是业内前100名风险投资家的排名,根据他们公开参与的交易数量排名。然后,数字大师计算出他们投入每笔交易的估计金额--按玩家人数分配现金--以表明他们是如何管理自己的辛迪加的。 一周多一点后,BrainStorm公司承认FDA的监管机构已经通知他们,该生物技术公司需要更多的数据才能获得ALS治疗NurOwn的批准--同时仍在吹捧疗效的“明确信号”,并不排除申请--该机构决定在一份最不寻常的声明中澄清记录。 FDA的声明完全是对自己的一记耳光,它提供的药效数据与该公司去年11月的公开声明不同,并且排除了任何统计意义的可能性。 过去十年,制药商已经证明JAK抑制剂可以治疗从类风湿性关节炎到COVID-19等一小部分免疫相关疾病。现在礼来又拿出了一个新的。 礼来及其生物技术合作伙伴Incyte周三宣布,他们的JAK抑制剂baricitinib在一项针对斑秃的III期试验中有效地修复了患者的头发。斑秃是一种会导致突然、严重和斑片状脱发的自身免疫性疾病。礼来没有对546名患者的试验结果进行分析,但主要终点是脱发症状标准评分的改善。 CRLS.483s.CBER、CDER和RWE。对于生物制药专业人员来说,这些首字母缩略词之所以引起注意,是因为FDA在药物开发中起着重要作用。现在Endpoints正在加倍扩大监管覆盖范围,并推出一份关注White Oak公司发展的周报,并对这一切意味着什么进行分析和洞察。 报道将由我们新的高级编辑Zachary Brennan领导。他加入了POLITICO的端点,在那里他报道了制药。在此之前,他是管理事务专业人士协会的新闻刊物《管理焦点》的执行编辑。 引发第三波Covid-19疫苗供应开始席卷美国所需的所有部件都在周末顺利就绪。 在短暂地展示了监管的明智性后,FDA于周六紧急批准强生公司的新冠疫苗,为拜登政府旨在近期结束疫情的计划增添了一笔--至少是在美国。CDC于周日通过了批准,强生公司预计将在未来几天内开始提供疫苗。 索蒂克莱斯塔特成功了。 在委托奥维德大学的研究小组进行中期临床工作四年多后,竹田正将这种药物重新纳入自己的阵营。由于所有这些--在Dravet综合征和Lennox-Gastaut综合征中产生了他们认为是积极的第二阶段数据--生物技术公司获得了1.96亿美元的预付现金,另外6.6亿美元用于监管和商业里程碑。 去年11月,默克公司斥资4.25亿美元收购了OncoImmune,大概是因为他们相信,他们可以扩大其治疗重症Covid-19的药物的规模,并借助9月份完成的一项III期试验(规模较小的biotech)通过FDA的审批。 FDA否决了这些计划。该机构上周告诉默克公司,这项203人的研究并不足以证明这种药物是有效的。据彭博社报道,默克公司正在准备一项新的第三阶段研究,这项研究将把结果和任何批准的机会推到今年年底。 当Michael Shpigelmacher开始这个项目时,他知道他必须自己出资。其他类似的努力都是学术性的,被投资者认为风险太大而拒绝。 Shpigelmacher是一名机器人专家,也是一名企业家,曾在制药公司从事咨询工作,他想要建立一种与上世纪60年代电影《神奇航程》中的技术相当的现实生活中的技术,在这部电影中,一名潜艇艇员被缩小到“大约一个微生物的大小”,并被派去修复一名科学家的大脑。他扫描了文献,找到了正在进行最先进项目的实验室--原来是在德国的马克斯普朗克研究所--并开始用他和他的联合创始人自己的账户,以及朋友和家人提供的一些种子资金来资助他们。
