Glossary Term
Precision Medicine
Definition
Precision medicine is an innovative approach to medical treatment and healthcare that uses information about an individual's genetic makeup, environment, and lifestyle to tailor treatment plans and interventions. Unlike the traditional "one-size-fits-all" approach, precision medicine seeks to customize healthcare for each patient, optimizing the effectiveness of treatments by targeting the specific factors influencing their health. This can involve using genetic testing, molecular profiling, and other diagnostic tools to better understand disease mechanisms and predict how patients will respond to different therapies.
Relevance to the MedTech Industry
Precision medicine aims to provide more personalized and effective healthcare by taking into account the unique genetic, environmental, and lifestyle factors that affect an individual’s health. This approach aims to improve treatment outcomes, reduce adverse effects, and increase the overall efficiency of healthcare by offering tailored interventions that are more likely to be successful for specific patients.

Examples of Precision Medicine Applications
Oncology:
In cancer care, precision medicine allows for the use of genomic testing to identify specific mutations in tumors, enabling oncologists to prescribe targeted therapies that are more likely to be effective.
Example: The use of NGS to identify mutations in non-small cell lung cancer (NSCLC) to guide treatment decisions, such as the use of targeted EGFR inhibitors.
Cardiovascular Diseases:
Precision medicine can be used to tailor cardiovascular treatments by analyzing genetic predispositions to heart disease, response to certain medications, and risk factors like cholesterol levels or blood pressure.
Example: Genetic tests that predict a patient’s response to statins or blood thinners, allowing for personalized management of cholesterol and heart disease risk.
Rare Genetic Disorders:
For patients with rare genetic disorders, precision medicine enables the identification of mutations that cause disease, leading to customized therapies or even gene therapies designed to address the root cause of the condition.
Example: Gene therapy for Duchenne muscular dystrophy, which targets the genetic mutation causing muscle degeneration and aims to slow the progression of the disease.
Pharmacogenomics:
Pharmacogenomics is the study of how genetic variations affect an individual’s response to drugs. By incorporating pharmacogenomic testing, clinicians can prescribe the most effective medications while minimizing adverse drug reactions.
Example: Genetic testing to determine the optimal dose of warfarin, an anticoagulant, based on the patient’s CYP450 enzyme variants to avoid bleeding complications.
Related Terms
Genomics: The study of the genome, or complete set of genes, in an organism, which is central to precision medicine in understanding the genetic basis of diseases.
Biomarker: A biological molecule or characteristic used as an indicator of a disease or condition, important for diagnosing or predicting treatment response in precision medicine.
Companion Diagnostics: Tests designed to guide the use of specific therapies based on molecular or genetic characteristics, often used in conjunction with targeted therapies.
Targeted Therapy: A treatment strategy that uses drugs or other substances to specifically target molecular pathways or mutations that drive disease, commonly used in precision medicine, particularly in cancer.
Pharmacogenomics: The study of how genetic variations affect drug responses, used to personalize treatment plans and optimize drug efficacy and safety.
