Summary
This study tests whether an open labeled placebo—a pill with no active medicine that patients know is a placebo—can reduce fatigue in people with advanced cancer. About 100 participants will either receive the placebo or be placed on a waitlist. The goal is to see if simply taking a placebo can improve fatigue and quality of life.
