Brief Summary
This phase III trial tests whether high-dose vitamin D works in treating androgen-deprivation therapy (ADT)-induced bone loss in patients with prostate cancer who are undergoing androgen-deprivation therapy. Vitamins are substances that the body needs to grow and develop normally. Vitamin D helps the body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets. This trial may help researchers determine if high-dose vitamin D helps keep bones strong, lowers number of falls, and lessens fatigue in men getting androgen-deprivation therapy.

Outcome Measures
Primary Outcomes (4)
Reduction of bone mineral density (BMD) loss as measured at the total hip
Will determine the efficacy of high-dose vitamin D (HDVD) supplementation versus placebo in reducing BMD loss as measured at the total hip via dual-energy x-ray absorptiometry (DXA) at 52 weeks. Will use analysis of covariance (ANCOVA) with group (vitamin D or placebo) as the main factor, baseline timepoint (\[T\]1) BMD as covariate, and week 52 (T3) BMD as the outcome. Study site will be included as a random effect independent of residual error. An initial linear mixed model (LMM) will be fit using Restricted Maximum Likelihood (REML) estimation. The significance of the variance due to study site will be tested using the Wald Test.
At 52 weeks
Reduction of BMD loss as measured at the femoral neck
Will determine the efficacy of HDVD supplementation versus placebo in reducing BMD loss as measured at the femoral neck via DXA at 52 weeks. Will use ANCOVA with group (vitamin D or placebo) as the main factor, baseline (T1) BMD as covariate, and week 52 (T3) BMD as the outcome. Study site will be included as a random effect independent of residual error. An initial LMM will be fit using REML estimation. The significance of the variance due to study site will be tested using the Wald Test.
At 52 weeks
Reduction of BMD loss as measured at the distal radius
Will determine the efficacy of HDVD supplementation versus placebo in reducing BMD loss as measured at the distal radius via DXA at 52 weeks. Will use ANCOVA with group (vitamin D or placebo) as the main factor, baseline (T1) BMD as covariate, and week 52 (T3) BMD as the outcome. Study site will be included as a random effect independent of residual error. An initial LMM will be fit using REML estimation. The significance of the variance due to study site will be tested using the Wald Test.
At 52 weeks
Reduction of BMD loss as measured at the lumbar spine
Will determine the efficacy of HDVD supplementation versus placebo in reducing BMD loss as measured at the lumbar spine via DXA at 52 weeks. Will use ANCOVA with group (vitamin D or placebo) as the main factor, baseline (T1) BMD as covariate, and week 52 (T3) BMD as the outcome. Study site will be included as a random effect independent of residual error. An initial LMM will be fit using REML estimation. The significance of the variance due to study site will be tested using the Wald Test.
At 52 weeks

Eligibility Criteria
You may qualify if:
- Be diagnosed with Stage I-IV prostate cancer without metastases to bone (lymph node involvement and prior diagnosis of a primary cancer is allowed)
- Be age 50 years or older
