Personalized Medicine
Taking a look at québec’s position in personalized medicine
WITH DR. cLARISSA DeSJARDINS Biotechnology Focus recently sat down with Dr. Clarissa Desjardins, chief executive officer of Cepmed, to discuss personalized medicine.

Cepmed is a non-profit organization dedicated to promoting the science and practice of personalized medicine through research, commercialization and education. It currently participates in several multi-million dollar public-private partnerships in translational medicine that incorporate pharmacogenetic testing into Phase III clinical trials and studies of marketed products. In addition, it funds strategic personalized medicine research projects with high commercialization potential and has embarked on a program to promote the principles of personalized medicine to healthcare practitioners and stakeholders across the country. Founded by the Montréal Heart Institute and Genome Québec, Cepmed makes use of the Beaulieu-Saucier Pharmacogenomics Centre, the Montréal Heart Institute Coordinating Centre and the Montréal Heart Institute Biobank in its projects. It is a Centre of Excellence for Commercialization and Research (CECR) and supported by the Canadian Government, Genome Québec as well as private partners including Pfizer, AstraZeneca, Novartis and Merck.

Biotechnology Focus: Can you give us a brief description of what personalized medicine is? Dr. Clarissa Desjardins: A common definition for personalized medicine is that defined in the President’s Council of Advisors on Science and Technology (PCAST) “Priorities for Personalized Medicine” September 2008, “Personalized medicine is the tailoring of medical Biotechnology Focus / October 2010
treatment to the individual characteristics of each patient. It does not literally mean the creation of drugs or medical devices that are unique to a patient but rather the ability to classify individuals into subpopulations that differ in their susceptibility to a particular disease or their response to a specific treatment. Preventative and therapeutic interventions can then be concentrated on those who will benefit, sparing expense and side effects for those who will not.” Personalized medicine may also be described as giving the right treatment, to the right person, at the right time. A patient’s genetic profile can indicate susceptibility to certain diseases (eg. BRAC1 and BRAC2 for breast cancer, LQTS for inherited arrhythmias) before they become manifest and allow the patient and physician to set out a plan for monitoring and prevention. In addition, a patient’s genes or proteins, as found in blood or other tissues, can indicate whether they are candidates for certain targeted drugs (eg. Her-2-positive breast tumors for Herceptin, BCR/ABL positive for Gleevec, CCR5 receptor for Selzentry HIV treatment), whether they should avoid certain treatments and side effects due to lack of efficacy in their particular tumour type (KRAS mutations, Erbitux, OncotypeDx) and whether certain treatments protocols should be modified to account for their particular way of processing drugs (P450 metabolic enzymes for a large number of current prescribed drugs). This new healthcare paradigm has been aptly named P4TM medicine by Leroy Hood (Institute for Systems Biology) in reference to its four key attributes: it is personalized, taking into account a person’s genetic or protein profile; it is preventative, anticipating health problems and focusing on wellness,
not disease; it is predictive, directing appropriate treatment, and avoiding drug reactions; and it is participatory, empowering patients to take more responsibility for their health and care. Therefore, the term personalized medicine is a concept, alternatively used to describe a social movement, technologies, medical approaches or specific diagnostic tests.
BF: In your opinion, why is personalized medicine such an important thing to invest in and research? CD: Personalized medicine is a disrup-
tive technology and a potential disruptive innovation to the healthcare industry, which means in has the potential to transform healthcare into products and services which are both cheaper and more effective.
BF: Do you feel the government is doing enough as far as supporting research in the area of personalized medicine? CD: First, the government invested in
an organization like Cepmed specifically dedicated to personalized medicine and we are grateful for this. Second, although the usual discourse is to claim that the government needs to invest more in any particular field of research, this does not tell the full story. Although it is true that the Canadian government has historically invested a smaller fraction of GDP in research than certain other countries, it is also a fact that Canadians have not done as well as most other countries in transferring the results of their research into commercial activity. The reasons for this are numerous and complex and not just a factor of the total R&D investment in a specific field.
