About this study

Official title: A Phase II Trial of Two Doses of Conjugated Estrogens (Premarin) in Patients With Androgen-Independent Prostate Cancer

The purpose of this study is to see if Premarin is useful against androgen-independent prostate cancer and to help understand how drugs such as Premarin may work.

Read the detailed description

Patients will be randomly assigned to one of two study groups (arm A or Arm B). Arm A will receive 1.25mg of Premarin once daily and arm B will receive 1.25mg of Premarin three times a day. Patients will also receive coumadin daily to help prevent thromboembolic disease.

After reviewing the first 30 patients on Arm A, it was determined that arm A (low dose Premarin) was not effective. Arm A was then closed and patients on Arm A were given the choice to switch to Arm B.

Treatment will continue until there is evidence of disease progression or unacceptable side effects.

Every 4 weeks while receiving Premarin, a physical exam and blood work will be performed. Every 12 weeks a CT scan of the abdomen and pelvis and a bone scan will be performed.

Patients will also be encouraged to undergo standard preventative breast irradiation prior to starting Premarin or up to 4 weeks after starting treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Premarin in people with Prostate Cancer, run by Dana-Farber Cancer Institute at 3 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 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 16 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 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?

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 efficacy of two different doses of Premarin in the treatment of patients with androgen-independent prostate cancer. 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 16 Jun 2011.
