Personalized Medicine
Personalized medicine (also known as precision medicine) is an approach to disease prevention and treatment that takes into account individual variability in genes, environment, and lifestyle for each person. It aims to tailor medical care to the specific characteristics of the patient and their disease.
Key Pillars
- Genomic Profiling: Analyzing a patient’s DNA to identify mutations or biomarkers that drive disease progression.
- Targeted Therapies: Using drugs designed to interfere with specific molecular targets associated with cancer growth and progression.
- Personalized Vaccines: Developing vaccines tailored to the unique neoantigens present in a patient’s tumor.
Clinical Applications in Oncology
mRNA Cancer Vaccines
Recent advancements in mRNA-technology have enabled the development of personalized cancer vaccines. These vaccines are designed to train the immune system to recognize and attack tumor-specific neoantigens.
- Moderna & Merck Collaboration: A significant milestone in personalized oncology involves the combination of a personalized mRNA vaccine with Keytruda (pembrolizumab).
- Indication: Adjuvant therapy for patients with Melanoma who have undergone surgical resection of high-risk disease.
- Mechanism: The vaccine (Intismeran Autogene) is custom-made based on the patient’s tumor mutational profile, while Keytruda acts as an immune checkpoint inhibitor to enhance the immune response.
- Trial Results: Positive Phase 3 trial results have been announced, demonstrating efficacy in preventing recurrence.

Other Areas
- Pharmacogenomics: Adjusting drug dosages based on metabolic enzyme profiles (e.g., CYP450 variants).
- Liquid Biopsies: Using circulating tumor DNA (ctDNA) for early detection and monitoring of treatment response.
