Checkpoint inhibitors are a very promising avenue for treating cancer. Imagine the immune system is a car, complete with brake and accelerator pedals, telling it when to move forward and attack, and when to stay still. Checkpoint inhibitors disengage the immune system’s brakes, allowing it to attack the cancer cells at full speed. Already approved to treat melanoma and certain lung cancers, therapies like Yervoy (ipilimumab), Keytruda (pembrolizumab), Opdivo (nivolumab), and others may have applications in dozens of additional cancer types.
