About this study

Official title: Evaluation of the Effect of 25-OH-Vitamin D3 Therapy on 15-Prostaglandin Dehydrogenase Expression in Primary Tumor and Normal Colorectal Mucosa in Patients With Colorectal Cancer

This pilot clinical trial studies cholecalciferol in treating patients with colorectal cancer. The use of cholecalciferol may slow disease progression in patients with colorectal cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To compare the expression of 15-hydroxyprostaglandin dehydrogenase (PGDH) messenger ribonucleic acid (mRNA) and protein levels in tumor tissue at baseline and after treatment with 25-hydroxy (OH)-vitamin D3 (cholecalciferol).

II. To compare the expression of 15-PGDH mRNA and protein levels in normal colorectal mucosa at baseline and following treatment with 25-OH-vitamin D3.

SECONDARY OBJECTIVES:

  1. To compare the expression of cyclooxygenase (COX)-1 and COX-2 mRNA in tumor tissues at baseline and after treatment with 25-OH-vitamin D3.

II. To compare levels of prostaglandin E2 (PGE2) in tumor tissue at baseline and after treatment with 25-OH-vitamin D3.

III. To compare the expression of COX-1 and COX-2 mRNA in normal colorectal mucosa at baseline and after treatment with 25-OH-vitamin D3.

IV. To compare levels of PGE2 in normal colorectal mucosa at baseline and after treatment with 25-OH-vitamin D3.

  1. To evaluate the tolerability of a single 100,000 international unit (IU) dose of 25-OH-vitamin D3.

OUTLINE:

Patients receive cholecalciferol orally (PO) 7 days prior to scheduled surgery or endorectal ultrasound. Patients are only followed through surgery or endorectal ultrasound. In case of a vitamin-D-related toxicity, the patient will be followed for resolution of the toxicity, up to 6 months.

Being tested
cholecalciferol, biopsy, protein expression analysis, enzyme-linked immunosorbent assay, laboratory biomarker analysis
Medical subject headings
Colonic Neoplasms, Rectal Neoplasms

Study groupRoleWhat they receive
Treatment (chemoprevention)ExperimentalPatients receive cholecalciferol orally (PO) 7 days prior to scheduled surgery or endorectal ultrasound. Patients with sigmoid colon cancer or clinical stage I rectal cancer would proceed with surgical resection without preceding chemoradiation and will have a portion of normal colorectal mucosa and tumor tissue obtained for research purposes.
Receives: Dietary Supplement: cholecalciferol; Procedure: biopsy; Genetic: protein expression analysis; Other: enzyme-linked immunosorbent assay; Other: laboratory biomarker analysis; Genetic: reverse transcriptase-polymerase chain reaction

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of the expression of 15-PGDH mRNA and protein levels in tumor tissue

    An increase in 15-PGDH expression will be defined as at least a 100% increase in mRNA by real-time reverse transcriptase (RT)-polymerase chain reaction (PCR) compared to baseline. Expression of 15-PGDH protein via ELISA in normal and tumor tissue at baseline and following treatment with vitamin D, as well as the absolute and fold changes will be summarized with descriptive statistics (e.g., mean, median, standard deviation, and interquartile range) and using box plots. In addition, 95% confidence intervals for the mean absolute and fold-changes in 15-PGDH levels will be calculated.

    Measured: 7-14 days after treatment

  2. Comparison of the expression of 15-PGDH mRNA and protein levels in normal colorectal mucosa

    An increase in 15-PGDH expression will be defined as at least a 100% increase in mRNA by real-time reverse transcriptase (RT)-polymerase chain reaction (PCR) compared to baseline. Expression of 15-PGDH protein via ELISA in normal and tumor tissue at baseline and following treatment with vitamin D, as well as the absolute and fold changes will be summarized with descriptive statistics (e.g., mean, median, standard deviation, and interquartile range) and using box plots. In addition, 95% confidence intervals for the mean absolute and fold-changes in 15-PGDH levels will be calculated.

    Measured: 7-14 days after treatment

Secondary outcomes (5)
  1. Comparison of the expression of COX-1 and COX-2 mRNA in tumor tissues

    Measured: 7-14 days after treatment

  2. Comparison of levels of PGE2 in tumor tissue

    Measured: 7-14 days after treatment

  3. Comparison of the expression of COX-1 and COX-2 mRNA in normal colorectal mucosa

    Measured: 7-14 days after treatment

  4. Comparison of levels of PGE2 in normal colorectal mucosa

    Measured: 7-14 days after treatment

  5. Number of patients with grade 3 related toxicities of a single 100,000 IU dose of 25-OH-vitamin D3

    Measured: 18-25 days after treatment

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing cholecalciferol, biopsy and protein expression analysis in people with Mucinous Adenocarcinoma of the Colon and Mucinous Adenocarcinoma of the Rectum, run by Case Comprehensive Cancer Center.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 17 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of the expression of 15-PGDH mRNA and protein levels in tumor tissue (time frame: 7-14 days after treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jan 2014.
