Substance Patent of Nucleic Acid Delivery Technology
was allowed in Japan
A patent application regarding a drug carrier for the nucleic acids* delivery was allowed on the
basis of an notice of allowance* by the Japanese patent office.
NanoCarrier and Kyoto University proceeds a basic research regarding a next generation platform
technology in relation to a polymeric carrier for an “artificial RNA system” on a basis of the
Research Collaboration Agreement. We, therefore, obtain a substance patent that is applicable to the
platform delivery technology for such nucleic acids due to the allowance in Japan.
Title of the invention:
PARTICULATE COMPOSITION AND PHARMACEUTICAL
COMPOSITION CONTAINING THE SAME
Patent application number: 2011-528907
Patentee:
NanoCarrier Co., Ltd.
Biotechnology-based drugs such as a nucleic acid are widely recognized as the next generation
drugs. However, the stability of such nucleic acids in body is very low and accordingly the utilization
of a carrier is inevitable to deliver appropriately to the target cells, the development of a great
potential carrier is now anticipated.
The Research Collaboration Agreement is intended to develop a novel nucleic acid pharmaceutical
due to a combination of the NanoCarrier’s polymeric micelle and the Kyoto University’s novel
nucleic acid system as is released on August 9, 2011 (http://www.nanocarrier.co.jp/en/news/topics/pdf/e20110809_2.pdf)
and we are running a chemosynthesis and drug efficiency evaluation of the novel pharmaceutical.
The financial forecast for the FY 2012 (April 2011~ March 2012) will not be affected by the allowance.
* Nucleic acids:
A drug candidate constituting of nucleic acids such as DNA and RNA.
*Notice of Allowance:
An official letter from the patent office that shows a good prosecution result when the patent
application is evaluated as a valuable invention to be granted. A patent right will be granted to the
applicant when the notice of allowance is issued and the patent registration fee is paid in by the
applicant.
