About this study

Official title: A PHASE III TRIAL OF THE USE OF LONG TERM TOTAL ANDROGEN SUPPRESSION FOLLOWING NEOADJUVANT HORMONAL CYTOREDUCTION AND RADIOTHERAPY IN LOCALLY ADVANCED CARCINOMA OF THE PROSTATE

RATIONALE: Patient abstract not available

PURPOSE: Patient abstract not available

Read the detailed description

OBJECTIVES: I. Compare locoregional control, disease-free survival, and overall survival in patients with carcinoma of the prostate who are considered at high risk of relapse and receive long-term adjuvant zoladex (ZDX) vs. no adjuvant treatment following neoadjuvant ZDX/flutamide and radiotherapy. II. Compare sexual function in patients treated with these two regimens.

OUTLINE: Randomized study. Arm I: Neoadjuvant Antiandrogen Therapy and Releasing Factor Agonist Therapy plus Radiotherapy. Flutamide, FLUT, NSC-147834; and Zoladex, ZDX, NSC-606864; plus external-beam irradiation using megavoltage equipment with energies of at least 4 MV (at least 6 MV preferred). Arm II: Neoadjuvant Antiandrogen Therapy and Releasing Factor Agonist Therapy plus Radiotherapy followed by Adjuvant Releasing Factor Agonist Therapy. FLUT; and ZDX; plus external-beam irradiation using equipment as in Arm I; followed by ZDX.

PROJECTED ACCRUAL: 1,508 patients will be accrued over 2 years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing flutamide, goserelin acetate and low-LET cobalt-60 gamma ray therapy in people with Prostate Cancer, run by Radiation Therapy Oncology Group.

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

Who may be eligible to take part?

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 28 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?

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00767286, which also lists 44 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 28 Jan 2014.
