Professor Espina provides an overview of how individualized cancer treatment is determined
Every individual’s disease is different. Personalized medicine strives to provide the right medicine for the right patient with the lowest toxicity. Personalized cancer therapy using proteomics involves molecular profiling of the patient’s cancer cells to map the susceptible drug targets and thereby guide therapy. Research, like that being done by the Center for Applied Proteomics and Molecular Medicine, provides strategies for personalized treatment with the goal of providing physicians key missing molecular information about the disease in each of their patients and improving the quality of life for patients.
Drs. Lance Liotta and Emanuel Petricoin III, co-directors of George Mason University’s Center for Applied Proteomics and Molecular Medicine (CAPMM), are pioneers in the field of patient-tailored research and personalized medicine. Using a novel and first of its kind drug target mapping technology that creates a unique profile or “fingerprint” of which drug targets are activated in each patient’s tumor, CAPMM’s researchers are tailoring treatment for each patient based on the unique characteristics of the patient's cells. Their goal – to offer hope by making diseases such as cancer and Alzheimer’s manageable for every patient.
The Side-Out Metastatic Breast cancer trial was announced at the annual meeting of the American Society of Clinical Oncology (ASCO) and is expected to expand into phase two this month.
The pilot study was the first of its kind to utilize novel protein activation mapping technology along with the genomic fingerprint of cancer as a way to find the most effective treatment. Results indicate that while prior standard chemotherapy failed the 25 women who participated in the 2.5 year pilot study, nearly half of the patients enrolled in the Side-Out trail had at least a 30 percent increase in progression-free survival.
This molecular approach creates opportunities for new therapies. For example, if a breast tumor shares the same protein pathway activation shared with lung cancer, then the drug developed to hit that target for lung cancer can be used now for breast cancer. The pilot study included only FDA-approved drugs currently on the market. Additional studies are expected to fold in new drugs as they become available with experimental drug.

Based on the results of this trial, CAPMM and the Side-Out Foundation are expanding this study to a new trial that is set to launch within the next month.
