The Parkinson's Pipeline Project was initiated in 2001 in response
to the lengthy, rigorous process of science, which has provided people with
so many medical miracles, and to the trends in research and politics. Spurred
by increases in research funding and the resulting advances of science,
the project focuses on working with industry to deliver the cure. As
illustrated in the diagram, the
project endeavors to fill the gaps between scientific research and new treatments
and between scientific discovery and cures for patients.
Advances in Research Funding and Science
The emphasis on brain science in the "Decade of the Brain", along with
continually growing investments in basic science at NIH and elsewhere,
are adding knowledge of neuro-science an accelerated rate. The burgeoning
reservoir of new scientific knowledge is ripe for translation into dramatic
improvements in treatment for a number of neuro-degenerative diseases.
Parkinson's in particular is poised for a breakthrough. Beginning
with the passage of the Udall Act in 1997, the PD community has been successful
in raising awareness and obtaining public research funding for PD. Indeed
more is known about Parkinson's disease than any other brain disease, and
in the context of large and growing (public and private) investments in bio-medical
science, PD has become a target of emphasis by the National Institutes of
Health (NIH). The NIH Parkinson's Research Agenda adopted in 2000 calls for
$950M in new research funding over 5 years, including significant efforts
in clinical trials and collaboration with industry. Dr. Zerhouni, appointed Director of
the NIH in 2002, has now targeted PD to become the example of a paradigm
of disease oriented research with an emphasis on translational research and
coordination of efforts across Institutes. In a strong partnership with the
NIH, Parkinson's advocates work to keep attention focused on results meaningful
to patients. The first item of business in the NIH-PD Community partnership
is collaboration on recruitment, retention and protection of human
subjects in clinical trials.
Advocacy and Industry
When advocates in Washington met in 1999 with Dr. Harold Varmus,
Director of NIH, he said, "you should be lobbying industry."
Working from the knowledge produced by science (NIH’s primary mission), he viewed the role of
industry as developing, manufacturing and distributing the
treatments. Now, ever closer to a cure, advocates are enlisting private
industry to widen the battle. The dynamics of the pharmaceutical industry
are an important element in the delivery of the cure. Development of a
new drug is a very long and costly endeavor with highly uncertain outcome.
Murphy’s law, “whatever can go wrong will go wrong,” is in full force when
it comes to intervening in the biochemistry of the brain. In addition corporate
strategies, investor expectations, and the size, maturity, and profitability
of the company are also important factors in determining the amount of
investment devoted to developing a drug.
Considerable research efforts are underway by the pharmaceutical industry.
Based on available information, we have compiled a comprehensive listing
of translational and clinical research underway by private industry including
stage of development and enrollment information where applicable:

The Pipeline
Starting from basic science the hunt for new treatments requires a lengthy
process of experimental and translational research and clinical evaluation
by sponsors, who are mostly in the pharmaceutical and biotechnology industry,
to create new drugs and procedures. This process is governed by regulatory
agencies, such as the FDA (U.S. Food and Drug Administration) and the EMEA
(European Medical Evaluation Agency), who set standards for the demonstration
of safe and effective use of new treatments by humans before they are available
to the public. The translational research process alone takes a minimum
of five years, usually more. The clinical research process usually takes
another five or more years. According to the Tufts Center for the
Study of Drug Development, the average time from scientific discovery to
approval is now 14.2 years. Neurological treatments are longer than
the average.
As the ultimate customer of both the regulatory agencies and Industry,
patient groups have a stake in the results of the evaluation process for
new treatments. Science is inherently slow, and for those with a
serious degenerative disease time is an enemy. Patient groups have
common interests with pharmaceutical manufacturers, who have time limited
patent rights, to expedite this process. Actualization of a cure
(See
Illustration) for Parkinson's
disease involves a series of steps starting with translation of basic research
into medical interventions, which must then be proven to be safe and effective,
and lastly, must be accessible to the population. All the science of
the NIH and private foundations plus all the resources of private industry
available to discover and create a breakthrough treatment are funneled through
a critical evaluation and review process of 10 to 15 years or more by the
FDA. Even then the cure is not automatically available to everyone;
it must be filtered through the health care system before it reaches patients.
The pipeline project and the companion Quadpac (Quality Access
and Delivery of Parkinson's Care) program are designed to take those extra
steps to realize the cure.
