Prana Selected for "Hot Topics" and Alzheimer's Association Press Briefing at ICAD

Dr. Jeffrey Cummings to Present Recent Clinical Trial Results

MELBOURNE, AUSTRALIA--(Marketwire - July 17, 2008) - Prana Biotechnology Limited (NASDAQ: PRAN) (ASX: PBT), a biopharmaceutical company focused on the research and development of treatments for neurodegenerative disorders, today announced that Dr. Jeffrey Cummings, the Chairman of Prana's Research and Development Advisory Board has been invited to present findings from the company's Phase IIa clinical trial during the "Hot Topics" session at the 2008 International Conference on Alzheimer's Disease (ICAD) to be held in Chicago, Illinois. Dr. Cummings will be presenting a talk entitled "Targeting Abeta as a Modifying Therapy of Alzheimer's Disease: Safety, Efficacy and Biomarker Findings of a Phase IIa Randomised, Double-Blind Placebo-Controlled trial of PBT2" on July 30 at 11:15am.

Part of the Alzheimer's Association research program, ICAD is the world's leading forum on dementia research. The conference brings together more than 5,000 researchers, physicians and care providers from 60 different countries. The "Hot Topics" session is devoted to exciting advances in Alzheimer's therapy. Prana's drug, PBT2, is a novel and very promising approach to the treatment of Alzheimer's disease.

During the presentation Dr. Cummings will present data from Prana's latest clinical trial. In the 12 week study in mild Alzheimer's disease patients, PBT2 demonstrated safety and tolerability, reduced Abeta 42 in the cerebrospinal fluid, and improved Executive Function performance in select cognitive tests.

"In 2006 the Alzheimer's Association selected Prana's PBT2 pre-clinical data to be highlighted at ICAD's 'Hot Topics' session. Now, two years later, we are excited to be selected again, this time to discuss our clinical trial results," said Geoffrey Kempler, Prana's Executive Chairman. "This continued interest in PBT2 is very encouraging."

"We know that Abeta requires metals in order to become toxic in the brain and PBT2 protects the brain from this interaction. So we are increasingly optimistic about the prospects of PBT2 as a therapy for Alzheimer's disease, and our inclusion in Hot Topics and the associated Alzheimer's Association Press Briefing at ICAD is indeed very gratifying," concluded Mr. Kempler.

In addition to Dr. Cummings, five of Prana's scientists and consultants have also been invited to present their research at ICAD and will discuss PBT2:

--  Rudy Tanzi, PhD. July 27 at 10:50am
    Professor, Department of Neurology, Harvard Medical School, USA
    Genetic association studies in Alzheimer's disease -- Genetics can be
    used to guide drug discovery and development in AD.

--  Kaj Blennow, PhD. July 28 at 10:30am
    Professor, Neurochemistry Lab, Sahlgrenska University Hospital,
    Gothenburg, Sweden
    Overview of Biomarkers -- Cerebrospinal fluid biomarkers reflect the
    central pathogenic processes in AD, including the deposition of Abeta
    in plaques (the 42 amino acid form of Abeta, Abeta42). PBT2 has been
    shown to reduce Abeta42 in patients with mild AD after 12 weeks of
    treatment.

    Executive Director, Mental Health Research Institute, Victoria,
    Australia
    Rational therapeutic strategies for modifying Alzheimer's disease:
    Abeta oligomers as the validated target

--  Robert Cherny, PhD. July 29 at 3:45pm
    Associate Professor, Mental Health Research Institute, Victoria,
    Australia
    The 8-hydroxyquinoline analog PBT2 rapidly restores cognition and
    reduces soluble Abeta in Alzheimer's transgenic mice

--  Kevin Barnham, PhD. July 30 at 3:00pm  *Hot Topics Session*
    Associate Professor, Department of Pathology, University of Melbourne,
    Victoria, Australia
    Therapeutic inhibition of GSK3beta decreases Abeta oligomers, decreases
    tau phosphorylation, and improves cognition in a mouse model of AD. --
    Further investigations into the mechanism by which Metal Protein
    Attenuating Compounds (MPACs), such as PBT2, can manipulate metals in
    the AD brain.

    -- July 28 at 12:30pm (Poster)
    Second generation MPAC PBT2 inhibits Tau phosphorylation and promotes
    Abeta degradation
