Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 120 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Baseline, at 1, 3, 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
Baseline, at 1, 3, 6 months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
