Exercise Training and NR Supplementation Trial to Improve Fitness in AYA HCT Survivors

Phase 2RecruitingNCT05194397

Children's Hospital of Philadelphia80 enrolled

Overview

This will be a randomized, placebo-controlled trial with a 2x2 factorial design testing the effects of an NAD+ precursor (NR) and exercise on skeletal muscle quality and VO2max in AYA HCT survivors. The primary outcome is the change in muscle strength (isometric knee extension) from baseline to 16 weeks. Key secondary outcomes are the change in muscle strength (ankle plantarflexion) from baseline to 16 weeks, the change in grip strength from baseline to 16 weeks, the change in lower extremity muscle mass from baseline to 16 weeks, the change in muscle OXPHOS capacity from baseline to 16 weeks, and the change in aerobic capacity (VO2 max) from baseline to 16 weeks.

Adolescents and young adults (AYAs) who undergo hematopoietic cell transplantation (HCT) are at an especially high risk of developing sarcopenia (loss of skeletal muscle mass), which occurs earlier than would be expected from advancing age alone. This is important as not only it doubles their risk for non-relapse mortality, but it also leads to premature cardiovascular disease. The investigators propose a mechanistic randomized controlled trial of home-based remotely supervised exercise (aerobic and resistance) training and supplementation with nicotinamide riboside, a precursor of NAD+, a metabolite that is critical for muscle metabolism, in AYA survivors of HCT. The findings will lay the critical groundwork for future trials to prevent or mitigate the myriad downstream adverse effects of low muscle mass in AYA HCT survivors.

Nicotinamide RibosideDIETARY_SUPPLEMENT

Investigators will use (Good Manufacturing Process) GMP-grade 300 mg capsules of the dietary supplement nicotinamide riboside (ChromaDex, Irvine CA). NR is distributed by ChromaDex, Inc., Irvine, CA. NR is available as 300 mg capsules. The dietary supplement will be re-labeled by the Hospital of the University of Pennsylvania (HUP) Investigational Drug Service according to FDA regulations, including subject and physician name and NR or Placebo 300 mg capsules.

PlaceboDIETARY_SUPPLEMENT

The matched placebo will contain the same excipients without the active supplement and is generally recognized as safe. The placebo will be covered in an identical capsule (NR will be covered in the same capsule)

Exercise InterventionOTHER

The exercise program consists of at-home training sessions and will include aerobic and strengthening components designed to progress persons gradually to 150-300 minutes of the equivalent of moderate aerobic activity, and twice weekly strengthening over 16 weeks. For aerobic training, the eventual intensity and duration goal (adapted for each person as necessary) will be for persons to train at 70-80% of peak 2MSPT heart rate 20-45 minutes 3-5 days/week. For resistance exercises the goal will be a load/weight that results in fatigue after 3 sets of 10-12 repetitions on 8-10 exercises 2 days/week.
