Prana's Lead Parkinson's Drug Presented at the 10th International Conference on Alzheimer's and Parkinson's Diseases

Evidence of Novel Neuroprotective Mechanisms With Disease Modification Potential

MELBOURNE, AUSTRALIA--(Marketwire - March 15, 2011) - Prana Biotechnology Limited (NASDAQ: PRAN) (ASX: PBT), announced that its Head of Research, Assoc. Prof. Robert Cherny, presented new data on PBT434, the Company's lead compound in pre-clinical development for Parkinson's Disease on March 12th at the 10th International Conference on Alzheimer's and Parkinson's Diseases in Barcelona. The oral presentation is titled, "PBT434: A Novel Neuroprotective Drug for PD." The presentation will be available later today on Prana's website

Prana previously announced the election of PBT434 as its lead drug candidate in September 2010, when the first efficacy data with the drug was published at the World Parkinson's Congress. Importantly, unlike most other PD drugs on the market or in development today, PBT434 does not artificially manipulate levels of the neurotransmitter dopamine. Dopamine controls motor function, and when the cells that produce dopamine, the substantia nigra, die motor control and function are diminished. Instead, PBT434 works upstream by preventing the initial cascade of substantia nigral cell loss, and the subsequent loss of motor function. The presentation included data from three different animal models supporting the disease modification therapeutic strategy of the drug. 

PBT434 is derived from Prana's 600 strong library of Metal Protein Attenuating Compounds (MPACs) that have been developed as neurologically active, brain penetrant, orally available compounds targeting neurodegeneration.

Geoffrey Kempler, Prana's Executive Chairman commented, "What is so exciting about the development of PBT4343 for Parkinson's Disease is that we hope the drug will treat patients from early diagnosis and minimize dependence on dopamine supplementation which becomes difficult to manage and often ineffective as the disease advances."
