About this study

Official title: Molecular Targeting of 15-LOX-1 for Apoptosis Induction in Human Colorectal Cancers

Primary Objective:

  • To determine whether celecoxib downregulates GATA-6 expression to upregulate 15-LOX-1 expression and induce apoptosis in human rectal tumors, researchers will measure GATA-6 and 15-LOX-1 expression, 13-S-HODE levels, and apoptosis rates in normal and colorectal polyp epithelial tissues before and after 6 months of celecoxib treatment of patients with familial adenomatous polyposis (FAP).
Read the detailed description

Celecoxib is a drug that was developed to treat arthritis. However, celecoxib may also help to stop or slow the growth of colon and rectal tumor cells.

At the start of the study, you will be asked questions about your medical history, have a complete physical exam, and have around 2 tablespoons of blood drawn for blood tests as part of your routine care for familial adenomatous polyposis. Also, blood tests such as fasting blood glucose and lipid profiling (cholesterol, LDL, HDL and triglyceride) will be assessed to determine eligibility. Women who are able to have children must have a negative blood pregnancy test within 14 days of starting celecoxib.

Before your scheduled colonoscopy, you will fill out a form asking about any medications and nutritional supplements that you are taking. In addition, you will be asked to complete a diet history. This will help researchers to evaluate patients' dietary habits. The questionnaire takes about 15 minutes to complete. You will also have around 1 teaspoon of blood drawn to measure the amount of celecoxib in your blood. Then, during your already scheduled colonoscopy procedure, you will have additional tissue biopsies (the size of a pencil tip) of your colon taken. For a colonoscopy procedure, a flexible tube with a light attached to the end is used to look inside your colon/lower gut. The biopsies will be taken through the flexible tube using a special cutting tool. Up to 23 biopsy samples may be taken. The biopsies should take about 20 extra minutes to complete.

After the procedure, you will start taking celecoxib by mouth once every 12 hours for 6 months. You will also have around 1 teaspoon of blood drawn to measure the amount of celecoxib in your blood at the completion of month 2 and 4 of celecoxib treatment. At the end of the 6 month treatment period, you will have another colonoscopy procedure. This is an additional procedure performed solely for this study and is not part of your standard of care for the treatment of familial adenomatous polyposis. A second set of biopsies will be taken (23 maximum). These biopsy samples will be studied and compared to the samples taken before treatment with celecoxib. You will also have around 1 teaspoon of blood drawn to measure the amount of celecoxib in your blood.

You will be contacted by phone 72 hours after your first dose of celecoxib and then every 2 weeks for the study to check for any side effects you may be experiencing.

The maximum amount of time you will remain on this study is 6 months. If at any time, you experience any intolerable side effects, you will be taken off the study.

This is an investigational study. Celecoxib is FDA approved and commercially available for familial adenomatous polyposis patients to reduce polyp formation. Up to 40 patients will take part in this study. All will be enrolled at M. D. Anderson.

What is being measured

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

  1. 13-HODE Colonic Tissue Levels

    13-HODE colonic tissue levels measured by Liquid chromatography and tandem mass spectrometry measurements (LC/MS/MS) in colorectal normal and polyp tissues

    Measured: Baseline to post 6 months of celecoxib treatment

Secondary outcomes (1)
  1. PGE2 Colonic Tissue Levels

    PGE2 colonic tissue levels measured by Liquid chromatography and tandem mass spectrometry measurements (LC/MS/MS) in colorectal normal and polyp tissues

    Measured: at the baseline colonoscopy (or sigmoidoscopy in patients who had undergone colectomy) before the initiation of celecoxib, and the follow-up colonoscopy or sigmoidoscopy was performed after celecoxib treatment (month 6)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Celecoxib and Colonoscopy Biopsy in people with Familial Adenomatous Polyposis, run by M.D. Anderson Cancer Center at 1 site in United States.

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 8 inclusion and 19 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: finished, as of the sponsor's last update on 13 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Feb 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

13-HODE Colonic Tissue Levels (time frame: Baseline to post 6 months of celecoxib treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00503035, which also lists 2 linked publications.

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 13 Feb 2023.
