Creatine Supplementation and Resistance Training to Preserve Muscle Mass and Attenuate Cancer Progression

This is a parallel, double-blind randomized controlled trial to test the effects of 52-weeks of creatine monohydrate supplementation with resistance training (Cr+RT) compared with placebo (PLA) and RT (PLA+RT) with our team's established, effective, home-based, telehealth RT program in 200 metastatic castration sensitive prostate cancer (mCSPC) survivors receiving androgen deprivation therapy (ADT). The study team will evaluate muscle mass, health outcomes (fatigue, physical function, independence, insulin sensitivity, quality of life), and markers or cancer progression (prostate specific antigen, cell-free DNA) at baseline, mid-point, and 52-weeks. RT will be carried out twice weekly with elastic resistance bands, and the study will utilize an established creatine monohydrate supplementation protocol for creatine and PLA delivery.
