Weighing Treatment Options

The Manalis Lab’s suspended microchannel resonator platform has been adapted into a tool for predicting patient responses to specific cancer drugs. In collaboration with the laboratory of Keith Ligon at Dana-Farber Cancer Institute, researchers measured glioblastoma cells before and after treatment with the chemotherapy TMZ in order to detect tiny changes in mass which indicate treatment response. Only half of glioblastoma patients respond to TMZ, and the genetic marker for TMZ is not a reliable predictor of sensitivity for all patients. A study appearing in Cell Reports and funded in part by the MIT Center for Precision Cancer Medicine demonstrated that the method accurately predicted response to TMZ. Travera, co-founded by Manalis and Ligon, is currently testing patient samples from several cancer types with the aim of developing clinically validated lab tests.
