The Effect of Exercise and Nicotinamide Riboside Muscle Health and Insulin Resistance in Survivors of Childhood Cancer (NCT05023993)

The Effect of Exercise and Nicotinamide Riboside on Muscle Health and Insulin Resistance in Adult Survivors of Childhood Cancer With Prediabetes: A Pilot Feasibility Study

🔵 Active, Not Recruiting Observational / Diagnostic 📋 Clinical Research Protocol Sponsor: City of Hope Medical Center

🩺 Plain-English Summary (8th-Grade Level)

This trial studies the effect of exercise and nicotinamide riboside on muscle health and insulin resistance in adult survivors of childhood cancer with prediabetes (elevated blood sugar level that is not high enough to be considered diabetes). Nicotinamide riboside is a dietary supplement which is similar to vitamin B3. Information collected in this study may help the future development of regimens to improve metabolic outcomes such as muscle health and insulin resistance (when the body is not normally responding to insulin) in childhood cancer survivors.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (9 items) and avoid the listed exclusions (7 items).

Location: City of Hope Medical Center — Duarte, California

Age range: 18 Years
