PROFAST Intervention in Precursor Multiple Myeloma PROFAST

What's the purpose of this trial?

This is a 4-month randomized trial of a prolonged nightly fasting intervention (PROFAST) in 40 overweight and obese individuals with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and smoldering waldenstrom macroglobulinemia (SWM). The purpose of this study is to understand if fasting for a prolonged period of time during the nighttime hours is a strategy to prevent overweight and obese individuals from developing blood cancer.

This trial is currently open and accepting patients.
