Prana Secures Key PBT2 Patent in Japan and Completes Core IP Suite
MELBOURNE, AUSTRALIA--(Marketwire - April 11, 2011) - Prana Biotechnology (
Geoffrey Kempler, Prana's Executive Chairman, said: "This decision by the Japanese Office to grant a claim to PBT2 completes a suite of core patent rights protecting this asset in key markets including the United States, Europe, Japan and Australia, further bolstering our commercialization plans in both Huntington's and Alzheimer's Disease."
The Japanese patent has a twenty year term expiring on 16 July 2023, with a possible extension of term of up to 5 years under pharmaceutical protection provisions. Importantly there is no post-grant opposition process in Japan whereby third parties can register objections following this decision. In 2010, the company announced the grant of similar claims in Europe and the decision of the United States Patent Office to extend the term of the patent granted in the United States**.
PBT2 was selected from Prana's Metal Protein Attenuating Compound (MPAC) library as its lead development compound in Alzheimer's Disease in 2004 and has since successfully completed Phase I and Phase IIa* trials. The MPAC library has expanded and matured to generate over 600 novel, neurologically active compounds with leads in Parkinson's Disease, brain cancer and other potential neurological indications. Geoffrey Kempler noted, "Generating patentable and differentiated MPACs is the foundation of Prana's therapeutic pipeline."

** Patent term in the United States is calculated as 21 December 2025 which may be extended by the application of pharmaceutical extension of term provisions. In Europe the patent term, as for Japan, is to 16 July 2023 with possible extension of term of up to 5 years under pharmaceutical extension provisions.
