Further study details as provided by Roswell Park Cancer Institute:

Primary Outcome Measures:
  • Pattern of Response of Serum 25(OH) D3 Levels [ Time Frame: Baseline, at 1, 3, 6 months ]
    Change from Baseline in Serum 25(OH) D3 Levels at 1, 3, and 6 Months at dose levels 4000, 6000, 8000 and 10000 IU. Statistical analysis was done using one sample t-test.


Secondary Outcome Measures:
  • Pattern of Response of Parathormone [ Time Frame: Baseline, at 1, 3, 6 months ]
    Change from Baseline in PTH Levels at 1, 3, and 6 Months at dose levels 4000, 6000, 8000 and 10000 IU. Statistical analysis was done using one sample t-test.

  • Toxicity [ Time Frame: Baseline, at 1, 3 and 6 months ]
    Number of treated patients that had serious adverse events.

  • Occurrence of Infections, Deep Vein Thrombosis, Vascular Events, and Falls [ Time Frame: Baseline, at 1, 3 ,6 months ]
    Number of participant with occurrence of infections, deep venous thrombosis, vascular events and falls

Detailed Description:

OBJECTIVES:

Primary

  • To examine the pattern of response of serum 25(OH) D3 levels following cholecalciferol (vitamin D3) supplementation at four different oral doses in patients with prostate cancer.

Secondary

  • To examine the pattern of response of parathormone (PTH) following vitamin D3 supplementation in these patients.
  • To assess the toxicity of vitamin D3 supplementation in men with prostate cancer.

Tertiary

  • To track occurrence of infections, deep vein thrombosis, vascular events, and falls in these patients.

OUTLINE: Patients are randomized to 1 of 4 treatment arms.

  • Arm I: Patients receive 4,000 IU of oral cholecalciferol (vitamin D3) once daily.
  • Arm II: Patients receive 6,000 IU of vitamin D3 once daily.
  • Arm III: Patients receive 8,000 IU of vitamin D3 once daily.
  • Arm IV: Patients receive 10,000 IU of vitamin D3 once daily. Treatment in all arms continues for 6 months in the absence of disease progression or unacceptable toxicity.
