回复 与病魔抗争 的帖子
这是一个令人沮丧的好消息.
siRNA抗纤维化技术专利拥有者,日本日东电工与美国siRNA制药领域的先行者quarkpharma 公司 决定合作开发siRNA 抗纤维化药物.
对此消息感兴趣的朋友今后可以关注http://www.quarkpharma.com/qbi-en/newslist/QrkNitto/追踪药物研发的最新进展.
令人沮丧的是他们将在2012开始申请美国的新药临床试验(IND),预计到2018年投入应用.
8年10年的太漫长了,或许研发最终失败,或许有人会熬不到,熬到的人也已青春不再,失去了社会打拼的机会,人生只能因为活着而活着.
中国人连想成为人家高级医疗试验的试验品的机会都没有,在国内只能做自己埋单并且被损害的低级试验品.
为什么美国临床试验没有按疾病风险程度对临床实验分等级?
比如相对高风险的进展迅速的肝硬化,晚期癌症等疾病,降低临床实验的条件,缩短临床实验的时间.
这也附合风险受益匹配的原则,应该有一个最优的结果.
Nitto Denko and Quark Pharmaceuticals to Enter into Collaboration to Develop a Novel siRNA Anti-fibrotic Drug
Nitto Denko to use its specialty delivery vehicle, targeting technology for fibrosis with novel therapeutic concepts together with Quark proprietary RNAi technology, novel structures with FTO and siRNA clinical development expertise to file for an IND for a new anti-fibrotic drug
Osaka, Japan and Fremont, CA, July 15, 2010 - Nitto Denko Corporation, Japan’s leading diversified materials manufacturer and Quark Pharmaceuticals, Inc., a world leader in the discovery and development of RNAi-based therapeutics, today announced the initiation of a collaboration and license agreement for the development of siRNA therapeutics for the treatment of fibrotic diseases. These results support the further evaluation of QPI-1007 as a potential novel treatment for glaucoma.
The collaboration is designed to develop siRNA drugs using Quark’s RNAi technologies and novel structures providing freedom to operate in the siRNA intellectual property space and Nitto Denko’s drug delivery technologies for novel therapeutic concepts, currently owned by Nitto Denko. This refers to the concepts developed in a groundbreaking research by Prof. Yoshiro Niitsu of Sapporo Medical University, School of Medicine, Sapporo, as published in Nature Biotechnology Vol. 26 Issue 4 Pg. 431-42 (Apr 2008).
The collaboration will have an initial budget of double-digit million US dollars to achieve the first IND at the US FDA by early 2012.
“We are very pleased to collaborate with Nitto Denko in developing siRNA drugs. This collaboration is a perfect marriage between the core competencies of the two companies; we shall be using our technologies, intellectual property and capabilities to quickly bring drug candidates to clinical stage and Nitto will provide its delivery technologies and therapeutic strategy as well as their world class capabilities in oligonucleotide production." said Daniel Zurr, Ph.D., Quark’s CEO.
Mr. Kageshi Maruyama, Nitto Denko’s Officer, commented: "We are delighted to initiate this siRNA program. We believe siRNA is going to make a very important impact to the field of pharmaceuticals discovery and development. With its production facilities and extensive research, Nitto Denko is geared to have a very active participation in this market. We are pleased to work with Quark, we selected Quark due to the superior characteristics of its siRNA structure and chemical modifications, distinguished for the fact that have caused no immune response and look forward to utilizing this technology to create innovative medicines."
“I am very confident that siRNA drugs directed simultaneously to one or more specific target genes are the appropriate approach for therapies for a number of fibrotic diseases that are currently a totally unmet medical need.” commented Prof. Niitsu. “Our research has demonstrated that the adequate siRNA, appropriately delivered to the liver caused regression of liver fibrosis and significantly prolonged survival time in siRNA treated animals. It is very likely that this approach is suitable to fibrotic diseases in other organs
as well.”
