Overview

Pharmacogenomics (PGx) is the study of the role of inheritance in variation in drug response, either efficacy or toxicity. Research in the Pharmacogenomics and Drug Targets Laboratory focuses on the pharmacogenomics of antineoplastic agents. Most anti-neoplastic drugs have narrow therapeutic indices. Therefore, treatment with these drugs can result in significant, sometimes, life-threatening drug-induced toxicity.

At the same time, the therapeutic response to those agents is variable. For example, aromatase inhibitors (AIs) that are used in the treatment of hormonal receptor positive breast cancer (the most common subtype of breast cancer) can result in severe toxicity causing patients to discontinue the lifesaving treatment. Additionally, 20% of patients experience cancer recurrence despite being on the drugs for many years.

It is important to predict which subpopulations will respond to the treatment in order to achieve better therapeutic effect and to avoid toxicity. This is the goal of pharmacogenomics and the future of medicine — individualized therapy.

Pharmacogenomics is a rapidly growing field, and it has already had real impact on the practice of medicine. Our lab is involved in every aspect of pharmacogenomics research from discovery and translation to implementation of PGx in clinic.
