    Data presented from the lowest two dose cohorts (100mg and 200mg ARO-HBV)
    Up to 4.0 log10 reduction in HBsAg observed following three doses of ARO-HBV
    ARO-HBV was generally well-tolerated in HBV patients

PASADENA, Calif.--(BUSINESS WIRE)--Sep. 6, 2018-- Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) will present initial clinical data for ARO-HBV, the company’s third generation subcutaneously administered RNA interference (RNAi) therapeutic being developed as a potentially curative therapy for patients with chronic hepatitis B virus (HBV) infection, at the 18th World Gastroenterologists Summit in Auckland, New Zealand. Data will be presented from the eight patients in the lowest two dose cohorts: 100mg and 200mg. The data demonstrate that three monthly doses of ARO-HBV led to a maximum reduction in circulating HBV surface antigen (HBsAg) of 4.0 log10, with mean reductions of approximately 2.0 log10 on day 85 in the 100 mg cohort and 1.4 log10 on day 71 in the 200mg cohort (currently the last complete data point available). All eight patients achieved greater than 1.0 log10 reductions in circulating HBsAg.

Safety data will be presented across all ten patient cohorts (n=40). ARO-HBV was generally well-tolerated with generally mild and self-limiting injection site adverse events being the most common reported event in chronic HBV patients, occurring in around 10% of injections. The other most commonly reported events included symptoms consistent with upper respiratory tract infection and headache.

These results represent the first clinical data presented on ARO-HBV, which leverages Arrowhead’s proprietary Targeted RNAi Molecules (TRiMTM) platform. The company intends to submit a late-breaking abstract with additional clinical data to the Liver Meeting®, the Annual Meeting of the American Association for the Study of Liver Disease (AASLD), being held in November 2018.

Bruce Given, M.D., Arrowhead’s chief operating officer and head of R&D, said, “These initial results from the first two multiple-ascending dose cohorts of the AROHBV1001 clinical study are encouraging and indicate that ARO-HBV is highly active. In addition, the drug appears to be generally well-tolerated, which is consistent with our experience to date with ARO-AAT, our TRiMTM enabled candidate for the treatment of Alpha-1 liver disease. We intend to submit late-breaking abstracts to the AASLD Liver Meeting for both ARO-HBV and ARO-AAT, and, if accepted, we look forward to presenting more complete data-sets, including additional dose levels and longer follow-up.”

Key new data to be presented at the 18th World Gastroenterologists Summit from the AROHBV1001 Phase 1/2 clinical study in patients with chronic HBV who received three monthly doses of ARO-HBV include the following:

    Mean reduction of HBsAg was 2.0 log10 (99%) on day 85 in cohort 2b (100 mg) and 1.4 log10 (96%) on day 71 in cohort 3b (200 mg)
        These may not represent nadir
    Maximum reduction of HBsAg was 4.0 log10 (99.99%)
    Minimum HBsAg reduction in all patients from cohorts 2b and 3b was 1.2 log10 (93%)
    Activity was demonstrated in all patient types (HBeAg pos/neg, NUC naïve/treated)
    ARO-HBV appeared to be generally well-tolerated

The keynote presentation, titled “Hepatitis B in focus: new biology, new targets and real hope for finite therapy,” will be delivered by Dr. Given on September 7 at 09:45 a.m. NZST. A copy of the presentation (see slides 21-23) can be accessed on the Events and Presentations page under the Investors section of the Arrowhead website.

AROHBV1001 (NCT03365947) is a Phase 1/2 study evaluating the safety, tolerability, and pharmacokinetic effects of single-ascending doses (SAD) of ARO-HBV in healthy adult volunteers, and evaluating the safety, tolerability, and pharmacodynamic effects of multiple-ascending doses (MAD) of ARO-HBV in patients with chronic HBV. Dosing in the SAD portion of the study is complete, and included five cohorts at dose levels of 35, 100, 200, 300, and 400 mg. Dosing in the MAD portion of the study is ongoing, and includes ten cohorts receiving three doses of ARO-HBV either weekly, bi-weekly, or monthly, and includes dose levels of 100, 200, 300, and 400 mg.

Arrowhead在世界胃肠病学家峰会上展示了新的ARO-HBV临床数据,证明了HBsAg减少
2018年9月6日美国东部时间上午7:30

最低剂量组(100mg和200mg ARO-HBV)的数据显示,三剂ARO-HBV ARO-HBV后HBsAg降低4.0 log10,HBV患者普遍耐受良好 - 加利福尼亚州PASADENA - (BUSINESS WIRE) - 九月6,2018- Arrowhead Pharmaceuticals Inc.

    最低剂量组(100mg和200mg ARO-HBV)的数据
    三剂ARO-HBV后观察到HBsAg降低4.0 log10
    ARO-HBV在HBV患者中通常具有良好的耐受性

加利福尼亚州帕萨迪纳 - (美国商业资讯) - 9月Arrowhead Pharmaceuticals Inc.(纳斯达克股票代码:ARWR)将展示ARO-HBV的初步临床数据,该公司的第三代皮下注射RNA干扰(RNAi)治疗药物正在开发,作为慢性乙型肝炎病毒患者的潜在治疗方法。 (HBV)感染,在新西兰奥克兰举行的第18届世界胃肠病学家峰会上。数据将来自最低两个剂量群组中的八名患者:100mg和200mg。数据显示,三个月剂量的ARO-HBV导致循环HBV表面抗原(HBsAg)最大降低4.0 log10,在100 mg组中第85天平均降低约2.0 log10,在第71天降低1.4 log10。 200mg队列(目前可用的最后一个完整数据点)。所有8名患者的循环HBsAg均降低了1.0 log10以上。

将在所有10个患者队列中呈现安全性数据(n = 40)。 ARO-HBV通常具有良好的耐受性,通常轻度和自限性的注射部位不良事件是慢性HBV患者中最常见的报告事件,发生在约10%的注射中。其他最常报告的事件包括与上呼吸道感染和头痛一致的症状。

这些结果代表了ARO-HBV上的第一个临床数据,该数据利用了Arrowhead专有的靶向RNAi分子(TRiMTM)平台。该公司打算在2018年11月举行的肝脏会议®,即美国肝病研究协会(AASLD)年会上提交一份含有其他临床数据的最新摘要。

Arrowhead的首席运营官兼研发负责人Bruce Given博士表示,“AROHBV1001临床研究的前两个多次递增剂量组的初步结果令人鼓舞,表明ARO-HBV具有高度活性。此外,该药似乎通常具有良好的耐受性,这与我们迄今为止与ARO-AAT(我们的TRiMTM能够治疗α-1肝病的候选者)的经验一致。我们打算向AROLD HBV和ARO-AAT的AASLD肝脏会议提交最新的摘要,如果被接受,我们期待提供更完整的数据集,包括额外的剂量水平和更长的随访时间。“

AROHBV1001第1/2期临床研究报告在第18届世界胃肠病学家峰会上提出的关于接受三个月剂量ARO-HBV的慢性HBV患者的重要新数据包括:

    在组群2b(100mg)中第85天HBsAg平均降低2.0log10(99%),第3a组(200mg)第71天平均HBsAg降低1.4log10(96%)
        这些可能不代表最低点
    HBsAg的最大降低为4.0 log10(99.99%)
    所有患者2b和3b患者的HBsAg降低最低为1.2 log10(93%)
    所有患者类型均显示活动(HBeAg pos / neg,NUC幼稚/治疗)
    ARO-HBV似乎通常具有良好的耐受性

主题演讲题为“关注乙型肝炎:新生物学,新目标和有限治疗的真正希望”,将于9月7日上午9:45在新西兰国家公园举行。可以在Arrowhead网站的Investors部分下的Events and Presentations页面(敏感词)问演示文稿的副本(参见幻灯片21-23)。

AROHBV1001(NCT03365947)是一项1/2期研究,评估ARO-HBV单次递增剂量(SAD)对健康成年志愿者的安全性,耐受性和药代动力学影响,并评估多重剂量的安全性,耐受性和药效学效应。慢性HBV患者ARO-HBV的升高剂量(MAD)。在研究的S​​AD部分中给药完成,并且包括剂量水平为35,100,200,300和400mg的五个队列。在研究的MAD部分中给药正在进行中,并且包括每周,每两周或每月接受三剂ARO-HBV的十个群组,并且包括100,200,300和400mg的剂量水平。

截至早上8点,涨幅37.52%,盘中最高点涨幅60%,确实是不错的股市反应,不过还是比较有观望的情绪吧。
按照arc520的试验结果,现在这个药物是有进步的,而且克服了弊端,同时,现在的联合用药思路,应该是比较容易接受的,箭头公司也曾经考虑过联合用药。
但试验么,总有个过程的。相对来说,这个药物已经很快了,直接一二期试验一起上,后效能否巩固,还要看配合的药物能否激发免疫。我个人觉得还是比较乐观的。

Arrowhead在美国大选前夜发布乙肝候选药物ARC-520被FDA叫停
生物360网11-10 11:10

当美国选举占据各大媒体头条新闻时,似乎为了尽量减少曝光,当地时间8日深夜,小市值公司Arrowhead Pharmaceuticals ($ARWR)宣布,其治疗乙肝药物ARC-520被美国FDA叫停临床研究,该药物之前曾被吹捧为可能治愈乙肝感染。Arrowhead公司也因为这则消息在9日上午受到打击,盘前交易中其股价下跌20%左右。
ARC-520旨在对逆转录过程的上游起作用,这和当前标准的核苷酸和核苷类似物起作用的位置类似。ARC-520中RNAs的小干扰(siRNA)旨在减少HBV蛋白以及用于生产病毒DNA的RNA模板水平。它的目的是对所有沉默的乙肝病毒基因产物起作用。
被FDA叫停的是正在12名患者中进行的Heparc-2004研究。公司在一份声明中表示“这是公司对灵长类动物的非临床毒理学研究中使用EX1(肝脏靶向,静脉给药运载工具)后,对所产生的问题做出的响应。”然而,该生物技术公司强调,FDA“没有表明临床试验暂停是基于任何人类临床表现。”
目前,Arrowhead公司还没有收到正式的书面通知。但是在来自FDA的口头通知中,暂停临床试验是由于正在进行的灵长类动物毒理学研究中,其最高剂量的死亡造成的。
Arrowhead公司称,这项研究包含“比人类临床使用更高剂量的EX1”和“高于公司以前的动物毒理学研究中使用的那些剂量”。造成这些动物死亡的原因还不清楚,但Arrowhead认为动物毒理学研究的结果显示与剂量水平有关。
早在8月这家位于加利福尼亚州的生物科技公司就宣布,已经通过投资者筹集了4500万美元现金,以帮助加强其药物研发。9月份公司又与安进公司($AMGN)签约了价值6.74亿美元心血管RNAi协议。
Arrowhead公司正在开发多种基因沉默技术,并向诺华支付了3500万美元购买了大部分RNAi资产以及三个临床前候选药物权益。
2011年,Arrowhead购买了罗氏($RHHBY)RNAi平台,从而把这项技术从大型制药公司迁移到小型生物技术公司。
同时,Arrowhead一直在和RNAi专家Alnylam公司($ALNY)进行竞争,争取获得第一个上市的RNAi药物。
Alnylam公司最近也有自己的麻烦,由于在I 期和II期临床试验时使用最高剂量导致3名患者肝酶升高,结果导致了停止RNAi肝病候选药物ALN-AAT的开发。受此消息影响,在9月下旬交易中损失了约5亿美元的市值。
