The complexity of individual tumors creates a challenge for physicians to determine the optimal treatment for any given patient. This complexity may also require a combination of therapies to target the multiple pathways a given cancer may exploit to grow and spread. My Personalized Therapeutics is taking a model systems approach to pair patients to customized drug regimens by using fruit fly models of a patient’s cancer to screen hundreds of FDA approved therapies and combinations. We spoke to Laura Towart, co-founder and CEO of My Personalized Therapeutics, about the company’s Personalized Discovery Process, how it works, and why it may lead to better outcomes for cancer patients.
