Sean Parker’s cancer institute may have found a blood test to see if patients will respond to treatment

Scientists in collaboration with tech billionaire Sean Parker’s Institute for Cancer Immunotherapy may have found a way to predict whether melanoma patients will respond to treatments that target the PD-1 (programmed cell death protein) pathway in tumors through a simple blood test, according to a paper in the scientific journal Nature.

The former Facebook president launched the institute with his moniker and persuaded hundreds of top scientists within various research universities across the U.S. to form an alliance to solve cancer using cutting-edge immunotherapy, floating $250 million of his own $3 billion fortune to do so.
