  Purpose

This randomized clinical trial studies how well cholecalciferol supplement works in treating patients with localized prostate cancer undergoing observation. Cholecalciferol may help prostate cancer cells become more like normal cells, and to grow and spread more slowly.


Condition Intervention Phase
Adenocarcinoma of the Prostate
Stage I Prostate Cancer
Stage II Prostate Cancer
Stage III Prostate Cancer
Stage IV Prostate Cancer
Dietary Supplement: cholecalciferol
Drug: placebo administration
Other: active surveillance
Other: laboratory biomarker analysis
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study

Primary Outcome Measures:
  • PSA response [ Time Frame: Up to 21 months ] [ Designated as safety issue: No ]
    Assessed by approximate t tests.


Secondary Outcome Measures:
  • Pattern of response of PSA dynamics [ Time Frame: Up to 21 months ] [ Designated as safety issue: No ]
    Analyzed using the mixed model approach.

  • Absolute change in PSA [ Time Frame: Up to 21 months ] [ Designated as safety issue: No ]
    Analyzed using the mixed model approach.

  • Toxicity as assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 [ Time Frame: Up to 21 months ] [ Designated as safety issue: Yes ]
    Will be compared as difference in proportion with 95% confidence intervals.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the prostate-specific antigen (PSA) response with oral high dose vitamin D3 supplementation (cholecalciferol) in patients with localized, histologically proven adenocarcinoma of the prostate who have not received any treatment for prostate cancer ever and have chosen expectant management.

SECONDARY OBJECTIVES:

I. To examine the pattern of response of PSA dynamics as well as the absolute change in PSA following vitamin D3 supplementation.

II. Assess the toxicity of vitamin D3 supplementation in men with prostate cancer.

TERTIARY OBJECTIVES:

I. Track occurrence of infections, deep venous thrombosis, vascular events and falls in the study population.

II. To evaluate relationship between cytochrome P450 family 24 (CYP24), 27B1, single-nucleotide polymorphism (SNPs) and serum 25(OH) vitamin D response to oral D3 supplementation.

III. To assess the changes in functional assessment in response to 25(OH) vitamin D supplementation.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive cholecalciferol orally (PO) once daily (QD) for 9 months in the absence of disease progression or unacceptable toxicity. After a wash-out period of 3 months, patients cross-over to Arm II.

ARM II: Patients receive placebo PO QD for 9 months in the absence of disease progression or unacceptable toxicity. After a wash-out period of 3 months, patients cross-over to Arm I.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Male

Criteria

Inclusion Criteria:

  • Any patient with clinically localized, histologically proven adenocarcinoma of prostate who has not received any treatment for prostate cancer ever and has chosen active surveillance (treatment for prostate cancer is defined as prostatectomy, androgen deprivation, brachytherapy or a full course of external beam irradiation)
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Willingness to comply with study guidelines
  • Willingness and ability to consent
  • Vitamin D supplementation should not be done in any form other than that prescribed
  • 25(OH) D3 level less than 40ng/ml within 3 months of initiation of study; most recent 25 hydroxy D level within last 3 month would be used

Exclusion Criteria:

  • History of malabsorption syndrome (e.g., pancreatic insufficiency, celiac disease, tropical sprue)
  • Creatinine > 2.0mg/dL
  • Corrected serum calcium level of > 10.5 mg/dL (Serum Corrected Calcium= Serum Calcium + 0.8(4-Serum Albumin)
  • Most recent PSA value more than 18 months ago
  • Prior or current therapy for prostate cancer
  • Documented history of nephrolithiasis within the past 5 years
  • Patients receiving finasteride (Proscar) or dutasteride (Avodart) or men who have received either agent within 90 days of entry are ineligible
  • Ineligible if taking > 2000IU of vitamin D per day
