  Purpose

This is a study of HMB plus amino acids in older men with prostate cancer starting androgen deprivation therapy (ADT). The investigators hypothesize that the use of this nutritional supplementation will decrease the loss of muscle mass and strength that occurs when men start ADT.


Condition Intervention Phase
Recurrent Prostate Cancer
Drug: Standard of care ADT + (HMB + arginine + glutamine)

Primary Outcome Measures:
  • Prospectively measure the change in body composition in older men with prostate cancer (PCa) recurrence starting on ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Prospectively measure the fatiguability and muscle size using MRI/Phosphorus MRI spectroscopy (31P-MRS) in older men with PCa recurrence starting on ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
  • Prospectively analyze muscle fiber cross sectional area and fiber type using muscle biopsy in a subset of men with PCa recurrence starting ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
  • Prospectively measure the change in strength in older men with PCa recurrence starting on ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
  • Prospectively measure the change in physical performance measures in older men with PCa recurrence starting on ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
  • Prospectively measure the change in falls in older men with PCa recurrence starting on ADT, comparing those who receive HMB + AG versus those who do not. [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]

Detailed Description:

It is well established that older patients experience age-related loss of muscle mass and function (sarcopenia), presumably due to an imbalance of protein synthesis versus protein breakdown. In addition, studies have shown that men who start on ADT experience increased muscle protein breakdown and decreased synthesis. β-hydroxy-β-methylbutyrate (HMB), a leucine metabolite, has been shown to slow protein breakdown. When HMB is given with arginine and lysine (which support protein synthesis) in randomized trials, researchers have shown that elderly men and women who receive this nutritional supplementation experience improvement in fat-free mass, strength, functionality and protein synthesis when compared with controls. In addition, patients with advanced cancer who experienced weight loss of at least 5% have also been shown to benefit from HMB, with supplementation resulting in a significant increase of fat-free mass when compared to controls. Thus, it seems reasonable that older men with prostate cancer starting on ADT who experience lean muscle loss as a result of aging and ADT, may achieve some benefit from supplementation with HMB as well. Use of HMB in men with prostate cancer has not been reported.
