Open Labeled Placebo in Reducing Cancer Related Fatigue in Patients With Advanced Cancer

This phase II/III trial studies an open labeled placebo to see how well it works compared with waitlist control in reducing cancer related fatigue in patients with cancer that has spread to other places in the body. A placebo is not a drug and is not designed to treat any disease or illness. Recent studies have found that cancer related fatigue symptoms in cancer survivors are improved with open labeled placebo (that is, patients know they are taking a placebo). It is not yet known how well an open labeled placebo works when compared with waitlist control in reducing cancer related fatigue.
