About this study

Official title: A Randomized, Double Blind, Placebo-Controlled Trial of Celecoxib Versus Placebo in Men With Prostate Cancer With Rising PSA Following Prostatectomy or Radiation Therapy

The purpose of this study is to learn the effects (both good and bad) that celecoxib has on prostate cancer and patients with prostate cancer. This study is looking at what effects celecoxib has on prostate specific antigen (PSA) level. PSA is a marker specific to prostate cancer. An increase or decrease in this level in the blood can indicate if a patient's prostate cancer is getting worse or better.

Read the detailed description

This study is designed as a randomized, double blind, placebo-controlled study. These are all scientific research methods used to protect the study from personal bias or prejudice.

Patients who participate in this study will be randomly assigned initially to take either celecoxib (the study drug) or placebo (an inactive substance that looks like the study drug). Placebos are used to help determine if the results of a study (good or bad) result from chance or from treatment with the study drug. Patients will have a fifty-fifty chance of initial treatment with the study drug. Neither the patient nor the patient's doctor will know whether he/she is initially receiving the study drug or placebo. Participants who are assigned to initially take placebo may have the opportunity to be treated with celecoxib later in the study.

If patients are found to be eligible for this study and they agree to participate, they will be randomized to either receive celecoxib or placebo to be taken by mouth (as a pill) twice a day, every day for as long as they are in the study. Patients will be given a pill diary to keep track of their medications. While in this study, they will be asked not to take any non-steroidal anti-inflammatory drugs, which includes over-the-counter ibuprofen and many other available drugs. In addition, they will be asked not to take any other selective COX-2 inhibitors (the class of drug that celecoxib is).

While in this study, patients will have evaluations (physical exam and blood) to determine their response to their assigned regimen and to monitor side effects.

Once a month the following will be performed:

  • Review of any side effects
  • Physical Exam
  • Routine blood tests (PSA level, kidney function). About one tablespoon of blood will be taken at each visit.

Every other month starting with month 2:

In addition to the above evaluations, on alternating months starting with month 2, additional routine blood tests (liver function, complete blood count) will be done. This will require an additional tablespoon of blood to be taken at these visits.

Additional blood for research-related testing (about 2-3 tablespoons) will also be drawn during these visits.

Participation in this study will be determined by how well patients tolerate the assigned regimen and by how their disease responds. Patients will continue taking their assigned regimen for 6 months as long as it is felt that their disease is stable (based on their PSA levels) and they are tolerating the treatment. After 6 months or earlier, if the disease progresses, the treatment code will be broken. If patients were on celecoxib, they will be taken off study. The patient's doctor will discuss other available treatment options with him/her at that time, including continuing celecoxib "off study". If patients were on placebo, they will then have the option to begin taking celecoxib. If patients start celecoxib treatment, they will be treated in this study with celecoxib for 6 months or until their disease progresses. After 6 months on celecoxib or sooner, if their disease progresses, they will be taken off study. The patient's doctor will discuss available treatment options with him/her at that time, including continuing celecoxib "off study".

Patients who are taken "off study" will be monitored monthly for patient safety reasons throughout the duration of time that they are receiving celecoxib at the dose level used for this study (400mg twice a day).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

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

  1. To evaluate the biologic activity of celecoxib by comparing the proportion of men with a post-treatment PSA doubling time (PSADT) greater than or equal to 200% pre-treatment PSADT in the celecoxib-treated group compared to the placebo-treated group

Secondary outcomes (3)
  1. To compare changes in PSADT between the first and second six-month treatment periods for those in the placebo-treated group

  2. to correlate COX-2 expression in the patients' original prostate samples with biologic activity of celecoxib (when feasible)

  3. to correlate changes in plasma vascular endothelial growth factor (VEGF) levels in patients with biologic activity of celecoxib

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Celecoxib in people with Prostate Cancer, run by Dana-Farber Cancer Institute at 9 sites 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 7 inclusion and 11 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 9 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To evaluate the biologic activity of celecoxib by comparing the proportion of men with a post-treatment PSA doubling time (PSADT) greater than or equal to 200% pre-treatment PSADT in the celecoxib-treated group compared to the placebo-treated group. 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 9 Dec 2009.
