Four years after the GDNF phase II trials for  pump infusion delivery of GDNF were terminated by Amgen.... Further research and analysis has supported the belief that GDNF is one of the most promising neuroprotective therapies in the pipeline.  Hopefully AMT will move decisively ahead and will successfully develop GDNF gene therapy in the not too distant future.

AMT Obtains License to Amgen's GDNF Gene to Develop Treatment for
Parkinson's Disease with AMT's Proprietary Gene Therapy Platform     
(18/09/08 09:12 CET)

Amsterdam, The Netherlands - September 18, 2008 - Amsterdam Molecular
Therapeutics (Euronext: AMT), a leader in the field of human gene
therapy, today announced that it obtained a license from Amgen to use
their GDNF gene for the development of a gene therapy treatment for
Parkinson's disease. The combination of this gene with AMT's
proprietary adeno-associated virus (AAV) gene therapy platform could
potentially allow the development of an effective, long-term treatment
for this progressive and crippling disease.

Parkinson's disease is the second most common neurodegenerative
disease. It usually affects people over 65 with an estimated total of
4.5 million patients worldwide. Due to increasing life expectancy of
the general population, the number of patients with Parkinson's
disease is expected to double to around 9 million patients between now
and the year 2030.

Patients with Parkinson's disease slowly lose control of their
muscles, resulting in tremors, stiffness, slowness of movement, and
lack of coordination and thus in a serious loss of quality of life.
Parkinson's is caused by degeneration and death of nerve cells in a
specific part of the brain. These cells produce dopamine, a substance
necessary for communication between nerve cells involved in the
coordination of movement. Current therapies are limited to treatment
of symptoms. There are no therapies available that slow down or halt
the progression of the disease.

A new way to deliver the GDNF gene
"This license from Amgen offers us a unique opportunity to combine
our gene technology and know-how with the GDNF gene as a tool to
create a potential breakthrough in the treatment for this common and
severely debilitating disease," said Ronald Lorijn, CEO of AMT  "We
believe our gene therapy approach could be an effective way to deliver
the gene to the regions of the brain affected by Parkinson's disease."

Protect and improve nerve cells with GDNF
The GDNF gene contains the information for a protein necessary for the
development and survival of nerve cells. AMT will combine this gene
with its own proprietary technology to develop a gene therapy
treatment that aims to protect and enhance the function of the nerve
cells that produce dopamine. The positive effect of GDNF on nerve
cells has been shown in several animal studies, making it an
attractive candidate for the treatment of Parkinson's disease.. AMT
believes that its gene-delivery platform may potentially provide a
solution for delivering GDNF to the brain.

About Amsterdam Molecular Therapeutics
AMT has a unique gene therapy platform that to date appears to
circumvent many if not all of the obstacles that have prevented gene
therapy from becoming a mainstay of clinical medicine. Using
adeno-associated viral (AAV) vectors as the delivery vehicle of choice
for therapeutic genes, the company has been able to design and
validate what is probably the first stable and scalable AAV production
platform. As such, AMT's proprietary platform holds tremendous promise
for thousands of rare (orphan) diseases, especially the ones that are
caused by one faulty gene. AMT currently has a product pipeline with
seven products at different stages of development.
