About this study

Official title: A Randomized Trial of Antiestrogen Therapy Versus Combined Antiestrogen and Octreotide Therapy in the Adjuvant Treatment of Breast Cancer in Post-Menopausal Women

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen with or without octreotide may fight breast cancer by blocking the uptake of estrogen. It is not yet known which treatment regimen is more effective for breast cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen with or without octreotide in treating postmenopausal women who have stage I, stage II, or stage III breast cancer.

Read the detailed description

OBJECTIVES: I. Compare event-free, recurrence-free, and overall survival following adjuvant therapy with tamoxifen alone vs. tamoxifen plus octreotide long-acting release formulation in postmenopausal women with stage I/II/III breast cancer. II. Compare the toxicity and quality of life associated with each treatment regimen. III. Compare the effects of each treatment regimen on insulin-like growth factor-I (IGF-I) physiology, and study the relationship between IGF-I physiology and outcome.

OUTLINE: This is a randomized study. Patients are stratified by participating institution, when and whether they receive adjuvant chemotherapy, axillary lymph node status, and hormone receptor status. All patients are randomized within 12 weeks of definitive surgery. Patients receiving adjuvant chemotherapy prior to protocol treatment are randomized within 6 weeks after the last dose of chemotherapy. One group of patients receives daily oral tamoxifen, while a second group receives daily oral tamoxifen plus octreotide (long-acting release formulation) by monthly depot injection. Treatment in both groups continues for 5 years or until disease recurrence or development of a second malignancy. Patients are followed monthly for 4 months, every 4 months for 3 years, and every 6 months thereafter.

PROJECTED ACCRUAL: A total of 850 patients will be entered over 4.2 years in this multicenter study.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing octreotide acetate and tamoxifen citrate in people with Breast Cancer, run by NCIC Clinical Trials Group at 40 sites in 2 countries.

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 1 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in Canada, 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 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?

Event-free survival (time frame: 6 years). 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 NCT00002864, which also lists 8 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 1 Apr 2020.
