TWO NIH INITIATIVES LAUNCH INTENSIVE EFFORTS TO DETERMINE GENETIC AND
ENVIRONMENTAL ROOTS OF COMMON DISEASES
President's FY07 Budget Calls for $40 Million a Year Boost for
Multi-Year Effort; Companies to Commit More Than $25 Million to Launch
Genetics Project This Summer

The Department of Health and Human Services (HHS) today announced the
creation of two new, closely related initiatives to speed up research on
the causes of common diseases such as asthma, arthritis and Alzheimer's
disease.

One initiative boosts funding at the National Institutes of Health (NIH)
for a multi-institute effort to identify the genetic and environmental
underpinnings of common illnesses. The other initiative launches a
public-private partnership between NIH, the Foundation for the National
Institutes of Health (FNIH) and major pharmaceutical and biotechnology
companies, especially Pfizer Global Research & Development of New
London, Conn.; and Affymetrix Inc. of Santa Clara, Calif., to accelerate
genome association studies to find the genetic roots of widespread
sicknesses. The genetic analysis component of the two initiatives is
highly complementary.

GENES AND ENVIRONMENT INITIATIVE
HHS Secretary Mike Leavitt announced on Monday that the President's
budget proposal for fiscal year (FY) 2007 includes $68 million for the
Genes and Environment Initiative (GEI), a research effort at NIH to
combine a type of genetic analysis and environmental technology
development to understand the causes of common diseases. The FY 2007
budget represents a $40 million increase above the $28 million already
planned for these efforts in the NIH budget.

If approved by Congress, this additional federal funding will begin in
FY 2007 and continue for multiple years. Of the first year's funding,
$26 million will go to genetic analysis and $14 million for the
development of new tools to measure environmental exposures that affect
health.

"The discoveries made through these efforts will ultimately lead to
profound advances in disease prevention and treatment," Secretary
Leavitt said. "These are the kinds of innovative efforts that we should
support. We must seize the historic opportunity provided by the Human
Genome Project and the International HapMap Project, to speed up the
discovery of the genetic causes of common diseases like diabetes and
hypertension. At the same time, it's critical that we also understand
the environmental contributors to sickness, and the interplay among
genes and environment. There is not a moment to be lost."

GEI will have two main components: a laboratory procedure for
efficiently analyzing genetic variation in groups of patients with
specific illnesses and a technology development program to devise new
ways of monitoring personal environmental exposures that interact with
genetic variations and result in human diseases.

The proposed federal funding level will enable GEI to perform genetic
analysis - or genotyping -- studies for several dozen common diseases.
The exact diseases to be studied will be determined by peer review. An
initial survey of existing NIH-supported clinical studies identified
more than 100 with sufficient numbers of already characterized patients
to get this effort started. In addition, NIH expects to develop four new
environmental monitoring devices a year.

"This initiative would not have been possible a year or two ago," said
Elias A. Zerhouni, M.D., Director of the National Institutes of Health,
an agency within the Department of Health and Human Services. "This is a
tangible result of the nation's increased investment in medical research
over the past 10 years. We are now poised to combine what we have
learned from years of population studies, with newly available
technologies, developed with NIH support. These technologies reduced the
cost of genotyping by more than 100-fold, making such a comprehensive
effort affordable. Equally important, this effort will dramatically
increase our understanding of the environmental factors of health and
disease, and help us develop novel measures of gene-environment
interactions. We stand on the threshold of creating a future that will
revolutionize the practice of medicine by allowing us to predict
disease, develop more precise therapies and, ultimately, pre-empt the
development of disease in the first place."

PUBLIC-PRIVATE PARTNERSHIP
At the same time, a public-private partnership between NIH, FNIH, which
is a non-profit foundation established by Congress to support the
mission of the NIH; Pfizer and Affymetrix is being created to further
accelerate this important research on the genetic association studies.

The new partnership, called the Genetic Association Information Network
(GAIN), is being launched with a $5 million donation from Pfizer to set
up the management structure and $15 million worth of laboratory studies
to determine the genetic contributions to five common diseases.
Affymetrix, a biotech company that develops the types of tools used in
these kinds of genetic studies, will contribute enough laboratory
resources to study two additional common diseases. On average, it costs
about $3 million to carry out one study.

"We've translated early information from genetic research into valuable
medicines for HIV/AIDS, heart disease and the prevention of organ
rejection," said Martin Mackay, Ph.D., Senior Vice President Worldwide
Research & Technology, Pfizer Research & Development. "But these
advances have only scratched the surface of possible revolutionary
approaches to treat and cure diseases. Pfizer, the NIH and other
public/private biomedical research interests have complementary missions
greater than the sum of their parts. Our hope is that this
public/private initiative will encourage a deeper collective
understanding of the genetic factors of disease for major new
therapeutic advances."

GAIN will be an FNIH-managed partnership that includes NIH, industry,
foundations, individuals and advocacy groups. Governance will include an
executive committee, a steering committee, as well as peer review and
data access committees.

"Our partnership with pharmaceutical and biotech companies to speed up
this research exemplifies the aim Congress had in mind when it
established the Foundation for the National Institutes of Health to
support the mission of NIH," said John E. Porter, Vice Chairman of the
foundation's Board of Directors. "Through the financial support of the
private sector, NIH will now be able to launch into this exciting
initiative immediately. Moreover, the interaction of scientists from the
public and the private sector dramatically increase the likelihood that
this initiative will get off to a quick and efficient start that will
genuinely produce important advances for all patients."

GENETIC FACTORS
The genetic analysis of both GAIN and GEI will focus on the alternative
spellings -- called single nucleotide polymorphisms or SNPs -- that
normally occur in the order of the 3 billion DNA base pairs or letters
that make up a person's genome. SNPs are like single-letter misspellings
of a word. Most of these genetic variations are biologically
meaningless. But a small fraction of these SNPs alter the function of a
gene -- often only slightly. The combination of many slightly altered
genes may significantly increase the risk of a specific disease, but
identifying such a complex set of genetics changes is challenging.
Finding these disease-causing variants is one of the highest priorities
of current biomedical research.

"Virtually all diseases have a hereditary component, transmitted from
parent to child through the three billion DNA letters that make up the
human genome," said Francis S. Collins, M.D., Ph.D., Director of the
National Human Genome Research Institute at NIH and chairman of the GAIN
Steering Committee and co-chairman of the NIH Coordinating Committee for
GEI. "But progress in identifying the genetic factors that influence
health or disease, or even the response to treatment, is difficult. Both
initiatives promise to rapidly identify the myriad genes in an
individual that, taken together, contribute to an increased risk of
illness -- or that increase the chances of a healthy life. As the
genetic underpinnings of health and common diseases become clearer,
researchers will be empowered to develop targeted treatments that either
prevent illness from occurring or treat it effectively once it does."

There are about 10 million common SNPs in the human population. Scanning
the genomes of large numbers of patients for such a large number of
variants would be prohibitively expensive. Fortunately, a major shortcut
has been discovered that reduces the workload about 30-fold. The
International HapMap Project, led by the NIH and completed in October
2005, demonstrated that the 10 million variants cluster into local
neighborhoods, called haplotypes, and that they can be accurately
sampled by as few as 300,000 carefully chosen SNPs. New technological
systems allow these SNPs to be systematically studied in high-throughput
facilities that dramatically lower the cost.

For each study of 1,000 to 2,000 patients with a specific disease and a
similar number of people who do not have the illnesses (controls), an
investment of $3 million to $6 million (depending on the number of
patients and controls) is needed for the first stage of genotyping.
Follow-up studies to validate the results with additional patients and
controls, data analysis, and patient management expenses will add to
these basic costs. It is important to note, however, that these costs
are a small fraction of what has already been invested in enrolling
these study subjects, examining them, carrying out extensive laboratory
investigations, and collecting their DNA.

The genotyping work itself will be performed by either commercial or
government laboratories. The initial GAIN genotyping supported by Pfizer
will be carried out by Perlegen Sciences, Inc., of Mountain View,
Calif., and will start in late summer 2006; Pfizer is contributing these
Perlegen-produced genotypes as an "in kind" donation to the project. A
similar arrangement will be worked out with Affymetrix. Federally funded
genotyping for GEI will be managed by an NIH coordinating committee
under the usual government rules, subject to competition between
research facilities, and begin in FY 2007.

The research will lead directly to the identification of major genetic
susceptibility factors for common diseases of substantial public health
impact -- disorders such as heart disease, diabetes, cancer, stroke,
Alzheimer's disease, schizophrenia, osteoporosis, asthma, cataracts,
hypertension, Parkinson's disease, autism and obesity. The target
diseases and the populations studied have yet to be selected and will be
subject to a peer-review process.

ENVIRONMENTAL FACTORS
Genes alone do not tell the whole story. Recent increases in chronic
diseases like diabetes, childhood asthma, obesity or autism cannot be
due to major shifts in the human gene pool. They must be due to changes
in the environment, including diet and physical activity, which may
produce disease in genetically predisposed persons. Therefore, GEI will
also invest in innovative new technologies to measure environmental
toxins, dietary intake and physical activity, and to determine an
individual's biological response to those influences, using new tools of
genomics, proteomics and metabolomics.

"Differences in our genetic makeup certainly influence our risks of
developing various illnesses," said David A. Schwartz, M.D., Director of
the National Institute of Environmental Health Sciences, also part of
NIH, and co-chairman of the NIH Coordinating Committee for GEI. We only
have to look at family medical histories to know that is true. But
whether a genetic predisposition actually makes a person sick depends on
the interaction between genes and the environment. We need better tools
to evaluate environmental exposures, dietary intake and activity levels,
and then to determine how those risk factors interact with specific
genotypes to either maintain health or lead to disease. Without these
more precise measures of exposure, it will be very difficult to figure
out why certain people develop disease and others do not. We also need
to find out why a disease has such a different prognosis from one person
to the next. Given the recent advances in biomedical research, this is
the right time to take on this challenge."

To determine how the environment, diet and physical activity contribute
to illness, investments will be made in emerging technologies, such as
small, wearable sensors that can measure environmental agents that have
contact with the body and individual measures of activity. Devices also
will be developed that measure changes in human biology, which can be
observed in samples of blood or urine. In aggregate, these new tests
will provide the precision needed to help determine how these factors
influence the genetic risk of developing disease. The goal is to produce
devices for application to eventual population studies, to speed up data
processing, to enhance accuracy and to reduce cost.

With the $14 million annual investment in the environmental component of
this initiative, NIH will develop technologically advanced measures of
dietary intake, precise personalized measures of physical activity, and
biological measures that identify prior exposures to potential toxins
such as metals and solvents. NIH also will assess disease indicators
like inflammation and oxidative stress that are known to be influenced
by environmental toxins.

The National Center for Biotechnology Information, a part of the
National Library of Medicine at NIH, will develop databases to manage
the vast amount of genetic, medical and environmental information that
will emerge from these initiatives. To encourage rapid research
advances, and in keeping with the principles pioneered by the Human
Genome Project and increasingly common in such pre-competitive
public/private partnerships, all data generated through these
initiatives will be placed in the public domain.
