Our labratory analyzes living tumor cells, which are kept in 3-D clusters (microspheroids) that mimic the body’s environment. By examining cells in their native state, we take a snapshot of how they behave when exposed to various drugs, combinations and new targeted therapies. These microspheroids reflect the complex elements of the body’s cellular environment which has proven critical for the accurate prediction of clinical response. A true chemosensitivity test. And, we have been successfully refining and providing this service to patients for 20 years. Founded in 1995, Rational Therapeutics is a fully accredited laboratory with the sole purpose of testing cancer cells to determine which chemotherapy or targeted agent will kill an individual’s cancer cells. Through clinical trials, our technology (the Ex Vivo Analysis of Programmed Cell Death – EVA-PCD) has been shown to double response rates and increase survival times.
