                    Alnylam Pharma (ALNY) Commences ALN-HBV Phase 1/2 for HBV               
                           
             Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY) announced that it has initiated a Phase 1/2 clinical trial with ALN-HBV, a subcutaneously administered investigational RNAi therapeutic for the treatment of chronic hepatitis B virus (HBV) infection. The Phase 1/2 trial will be conducted initially in normal healthy volunteers, and, then, in chronic HBV patients. Initiation of this trial is based on encouraging pre-clinical data presented at the American Association for the Study of Liver Disease annual meeting in November 2015. The Company expects to report initial clinical data from patients in this study in mid-2017.

"We believe ALN-HBV has the potential to become a best-in-class, once-monthly, subcutaneous treatment regimen for the treatment of chronic HBV infection, including patients with both HBeAg-positive and HBeAg-negative disease” said Laura Sepp-Lorenzino, Ph.D., Vice President, Entrepreneur-in-Residence, and Program Leader for Alnylam’s Hepatic Infectious Disease Strategic Therapeutic Area (STAr). “We are encouraged by the pre-clinical results with ALN-HBV demonstrating potent and durable knockdown of plasma HBV surface antigen (HBsAg) in rodent models of HBV infection. High unmet need remains for safe and effective HBV therapies with the potential to produce functional cures after a finite treatment period.”

The Phase 1/2 trial of ALN-HBV is a randomized, single-blind, placebo-controlled study being conducted in three sequential parts. Part A is a single-dose study designed to enroll up to a total of 24 normal healthy volunteers (NHVs). Part B will be a single-dose study designed to enroll up to a total of 28 patients with chronic HBV infection. Part C will be a multi-dose study designed to enroll up to a total of 48 patients with chronic HBV infection. The primary objective of the study is to evaluate safety and tolerability of single and multiple subcutaneous doses of ALN-HBV. Secondary objectives include evaluation of pharmacokinetics and clinical antiviral activity for ALN-HBV as measured by its effects on serum HBsAg levels in hepatitis B envelope antigen (HBeAg) positive and negative chronic HBV patients.

ALN-HBV utilizes the company's Enhanced Stabilization Chemistry (ESC)-GalNAc-siRNA conjugate delivery platform, which enables high potency and durability with a very wide therapeutic index. Clinical results from other investigational RNAi therapeutic programs in Alnylam's pipeline that utilize ESC-GalNAc technology have demonstrated robust target gene knockdown and durability supportive of the potential for monthly, quarterly and, possibly, bi-annual subcutaneous dosing regimens, facilitating the potential for improved patient adherence.

ALN-HBV Pre-clinical DataPre-clinical study results in rodent HBV models showed that subcutaneous administration of ALN-HBV led to potent and durable knockdown of HBsAg. Single doses of ALN-HBV in mice resulted in an up to 3.6 log10 and a mean of 1.6 log10 reduction of HBsAg 15 days after a single dose. Further, multiple doses of ALN-HBV in rats showed highly durable knockdown, with effects lasting up to 4 months following three weekly doses of ALN-HBV at 3 mg/kg. In addition, ALN-HBV was generally well tolerated in 13-week GLP toxicology studies in rat and non-human primates.

Alnylam公司制药(ALNY)开始ALN-HBV 1/2期乙肝

Alnylam制药公司(纳斯达克股票代码:ALNY)宣布,该公司已经启动了1/2期临床试验ALN-HBV,给予研究用RNA干扰治疗慢性乙型肝炎病毒(HBV)感染的治疗皮下。阶段1/2试验最初将在正常健康志愿者中进行,并且,然后,在慢性HBV患者。这项试验的启动是基于鼓励在美国协会颁发的肝病年会于2015年十一月研究公司预计其在这项研究中,2017年中期患者最初的临床数据,临床前数据。

“我们相信,ALN-HBV有可能成为一个最佳的一流的潜力,用于治疗慢性HBV感染,包括患者兼有HBeAg阳性和HBeAg阴性患者每月一次,皮下治疗方案”劳拉说Sepp- Lorenzino,博士,副总裁,企业家驻场,与项目负责人Alnylam公司的肝脏传染病战略治疗领域(STAR)。“我们正在通过与ALN-HBV展示有力和持久的击倒临床前结果令人鼓舞在HBV感染的啮齿类动物模型等离子体HBV表面抗原(HBsAg)的。最高未满足的需求仍然是具有有限的治疗期后,以产生官能固化的潜在安全和有效的HBV疗法“。

阶段1/2试验ALN-HBV的是一项随机,单盲,安慰剂对照在三个连续部分正在进行研究。 A部分是一个单剂量研究旨在登记最多总共24名正常健康志愿者(NHVS)。 B部分将是单剂量研究,旨在招收最多,共28例慢性HBV感染。 C部分将是一个多剂量研究,旨在招收最多,共48例慢性HBV感染。该研究的主要目的是评价单次和多次皮下剂量的ALN - HBV的安全性和耐受性。如通过其对乙型肝炎包膜抗原(HBeAg)阳性和阴性的慢性HBV患者血清HBsAg水平影响测量的二次目标包括药代动力学的评价和临床的抗病毒活性为ALN - HBV。

ALN-HBV利用公司的增强型稳定化学(ESC)-GalNAc--siRNA缀合物递送平台,这使得高效力和耐久性具有很宽的治疗指数。其他研究性的RNAi治疗方案的临床结果Alnylam公司的管道,利用ESC-半乳糖胺技术已经证明了强大的靶基因敲除和耐用性支持的月度,季度和,潜在的​​可能,每两年一次的皮下给药方案,有利于改善病人的潜力坚持。

ALN-HBV临床前DataPre-临床研究结果在啮齿动物HBV模型显示,ALN-HBV皮下注射导致乙肝表面抗原有力和持久的击倒。小鼠单剂量的ALN-乙肝导致了高达3.6 log10的和单剂量后15天1.6 log10的减少乙肝表面抗原的平均值。此外,在大鼠多剂量ALN-HBV表现出高度耐用的击倒,具有持续效果长达4个月以下3毫克/公斤每周三剂量的ALN-HBV的。此外,ALN - HBV普遍以及在大鼠和非人灵长类动物13周的GLP毒理学研究的耐受性。

SK宣布将停止开发Ionis用于Transthyretin(TTR,一种转运蛋白)淀粉样变性的RNA药物IONIS-TTRrx,原因是临床III期临床试验中发现少数病人(不超过5人)有血小板严重下降副作用,但并未公开是否有病人因此死亡。Ionis股票暴跌40%。在此之前Ionis今年股票已经随着整个生物制药下降了65%。

Ionis原名叫ISIS,由于和臭名昭著的恐怖组织同名所以改成Ionis,也够倒霉的。Ionis是RNA药物的先驱,开始于80年代末。到目前为止只有两个药物上市。

GSK宣布将停止开发Ionis用于Transthyretin
Ionis - TTR 是反义药物(anti-sensense).
