Trial summary

Multiple trials have shown the efficacy of estrogen therapy in metastatic prostate cancer, and most recently trials have supported the use of transdermal estrogens (patch) in the patient population with a decreased risk of cardiovascular disease as compared to the oral estrogens.

About this study

Official title: Phase II Trial of Transdermal Estradiol in Patients With Hormone Refractory Prostate Cancer

Multiple trials have shown the efficacy of estrogen therapy in metastatic prostate cancer, and most recently trials have supported the use of transdermal estrogens (patch) in the patient population with a decreased risk of cardiovascular disease as compared to the oral estrogens. We plan to study the use of transdermal estrogen at a dose of 0.4mg qd. We will evaluate the toxicities and measure quality of life. We will assess PSA response and measurable disease response. This will be a trial available to the Cancer Institute of New Jersey Oncology Group. We will enroll a total of 33 patients. We will plan to enroll 10 at CINJ.Patients will wear the patches (4) continuously. We will obtain blood work and clinic evaluations every three weeks. We will assess quality of life through a questionnaire given to patient every three weeks.

What participants receive

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

  • Transdermal EstradiolDrug

    application of 4 transdermal estradiol patches, each patch releases a dose of 0.1 mg/day for a total dose of 0.4 mg/day. All four patches will be changed every 7 days. This continuous weekly schedule will be followed until the patient goes off-study.

    The patch will be applied to a clean, dry, intact area of the lower abdomen or the upper quadrant of the buttock. The sites should be rotated weekly. If a patch falls off during the 7 days, a new patch will be applied for the remainder of the 7 day period. At the end of the 7 days all four patches will be changed.

What is being measured

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

  1. Percentage of Patients With PSA Response

    PSA Response is a critical outcome measure used to assess the efficacy of treatments for conditions such as prostate cancer. PSA, or Prostate-Specific Antigen. The PSA Response is a measure of the change in PSA levels before and after a specific treatment intervention.

    Measured: 3 years

Secondary outcomes (4)
  1. To Measure Quality of Life of Participants Receiving Therapy With the Functional Assessment of Cancer Therapy-Prostate Scale (FACT-P).

    Measured: 3 years

  2. Measurable Disease Response Assessment in Participants With Hormone and Chemotherapy Refractory Prostate Cancer

    Measured: 4 years

  3. Time to Progression

    Measured: 3 years

  4. Plateau Level of Estradiol and Testosterone Response in Androgen-Resistant Population With 0.4mg/Day Transdermal Estradiol Patch

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Transdermal Estradiol in people with Prostate Cancer, run by University of Medicine and Dentistry of New Jersey at 6 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 10 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: stopped early, as of the sponsor's last update on 13 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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?

Yes. Results are posted in the registry (first posted 24 Dec 2013). 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?

Percentage of Patients With PSA Response (time frame: 3 years). 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 13 Sep 2023.
