Over the next 10 to 15 years, the worldwide pharmaceutical market is expected
to grow from about $300+ billion (2003 data on world-wide pharmaceutical
industry reports) to over a trillion dollars, driven primarily by the flood
of new drug targets some of them having been identified through genomics
and through the co-development of drugs and accompanying genomics response
tests. The primary objective of DNAPrint®‘s near term research
and development efforts in pharmacogenomics will be to expand our library
of predictive drug response tests to include multiple therapeutic areas which
include commonly used FDA approved drug therapies. Longer term, this
work will provide us the expertise to apply pharmacogenomics methods to our
own developing drug pipeline, to reduce the risk and expense of the clinical
trial process. A primary purpose of Phase II is for the drug-developer to
learn how to improve the drug’s response and better target the patient
population for the pivotal Phase III; if the drug works better in a segment
of the population then the company can design more effective Phase III clinical
trials to focus on that specific group of patients thereby maximizing the
efficacy and minimizing the side effects of the new medication. However,
most pharmaceutical companies and Clinical Research Organizations (CRO’s)
that run the trials; still do not employ powerful genome-based methods to
characterize their patients during the trial process. We hope that
by using our technology, we will be able to target our drugs to segments
of the population that are genetically compatible and thereby enjoy a higher
trial and post-market success rate. In many respects, we hope our medicines
will be more compatible with our patients over a longer period of time.
Although much of our efforts at present are mainly focused
on third-party drugs – those manufactured by other companies, we have
recently licensed in our first lead drug candidate, PT-401 a dimer of Erythropoietin. The
Erythropoietin monomer currently in the market is used to treat the anemia
associated with chronic renal (kidney) failure, anemia observed in cancer patients
on chemotherapy and in Zidovudine-treated HIV-infected patients, and in surgery
patients to reduce the need for allogeneic blood transfusions. PT-401
will be developed for similar indications and also for the treatment of new
conditions not related to anemia.
We currently have several pharmacogenomic tests
in development:
OVANOME™ - DNAPrint® scientists are working on a genomic-based
diagnostic tool to match ovarian cancer patients with the most suitable form
and dose of chemotherapy. Currently, cancer patients are treated with anti-cancer
drugs whose efficacy is known in terms of population averages. In reality,
individual cancer patients exhibit unpredictable and unique responses to virtually
all commonly used chemotherapeutic compounds. Individual genetic differences
have long been suspected to play a role in this variable drug response and
this is particularly true for the current standard of care for ovarian cancer – Paclitaxel
(Taxol) / Carboplatin (manufactured by Bristol-Myers Squibb). For cancer patients,
decisions about treatment regimes are often fateful, and second chances at
treatment are sometimes not successful. A better understanding of the relationship
between genes and drug response can replace the current trial and error process
of chemotherapy treatment and guide physicians and patients toward the optimal
treatments at the outset of therapy. In early March 2000, DNAPrint™ announced
success with this project at the Society of Gynecological Oncologists meeting
in Miami, and at the BIO IT World Expo in Boston.
Our scientists have identified several Single Nucleotide Polymorphism
(“SNP”) markers whose haploid alleles are predictive for non-response
to the Taxol and Carboplatin drug combination.
The next step for OVANOME™ is to be tested in prospective
clinical trials. These trials will give the final validation and determine
the clinical usefulness of the predictive test. . Our Chief Medical Officer,
Hector J. Gomez, MD, PhD will lead the clinical development process.
FDA rules regarding pharmacogenomics testing are still evolving
and everyone in the industry is seeking additional guidance from the FDA on
this issue. Until OVANOME™ is FDA approved or deemed to not require
FDA approval, we plan on generating revenues by developing and testing OVANOME
and similar tests for other drugs through physician guided Investigative New
Drug studies. Recently, we announced that we have begun a formal
evaluation of patient’s and patient samples in conjunction with the Moffitt
Cancer Center and associated Groups of specialists.
STATINOME™ - This test is currently being developed
for the cardiac drug market, and is expected to enable a classification of
patients as adverse responders or normal responders to a class of drugs known
as “statins”. Statins are drugs used to treat patients who are
at increased risk of heart disease. Approximately 50% of the U.S. population
is at risk of heart disease as a result of high cholesterol. While statins
have been demonstrated to be effective at cholesterol reduction, decreasing
incidence of heart disease by 10.3% from 1990 to 1994, adverse reactions can
include liver damage and kidney failure as well as potentially fatal muscle
degradation. Approximately 2-5% of patients must discontinue statin use due
to these adverse side effects. Once perfected, we believe STATINOME™ should
be able to improve the rewards associated with taking statins by reducing the
risks associated with adverse response sometimes seen in minority of patients.
In addition to OVANOME™, we have initiated several
studies for cancer drugs with the H. Lee Moffitt Cancer Research Center in
Tampa, FL (colon cancer, post-operative nausea and vomiting in cancer patients
undergoing surgery and multiple Myeloma). We hope to develop the additional
expertise to help us better guide the clinical development of compounds that
we will be acquiring for our own drug development pipeline.
