Vaccine Therapy in Treating Women With Metastatic Breast Cancer
A Phase 3 study testing Detox-B adjuvant, THERATOPE STn-KLH vaccine and keyhole limpet hemocyanin in people with Breast Cancer, run by Oncothyreon Canada Inc. at 1 site in Canada.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Vaccines may make the body build an immune response to kill tumor cells. Read more about this study

About this study
Official title: A Multi-Center Phase III Randomized, Controlled Study of Theratope Vaccine for Metastatic Breast Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Vaccines may make the body build an immune response to kill tumor cells. It is not yet known whether THERATOPE vaccine therapy is more effective than standard vaccine therapy in treating metastatic breast cancer.
PURPOSE: Randomized double blinded phase III trial to compare the effectiveness of THERATOPE vaccine therapy with that of standard vaccine therapy in treating women who have metastatic breast cancer.
Read the detailed description
OBJECTIVES: I. Compare time to disease progression in patients receiving THERATOPE vaccine to that of women receiving control vaccine. II. Compare survival in patients receiving THERATOPE vaccine to that of patients receiving control vaccine. III. Document the product safety profile in these patients. IV. Measure the anti-STn, anti-OSM, and anti-KLH antibody titers. V. Evaluate the impact of THERATOPE STn-KLH vaccine on health-related quality of life in these patients.
OUTLINE: The study design is a prospective, double-blinded, randomized study. Patients who have completed first-line chemotherapy for metastatic breast cancer and have either nonprogressive disease or no evidence of disease following completion of first-line chemotherapy (includes bone marrow transplants and stem cell rescue) will be randomized to either the THERATOPE vaccine or the control vaccine. Patients are stratified at entry according to disease status (i.e., either no evidence of disease or nonprogressive disease) and whether or not they are receiving hormonal therapy for metastatic disease while on study. Arm I: Patients receive intravenous cyclophosphamide on day -3, followed by 4 subcutaneous vaccinations with THERATOPE STn-KLH vaccine combined with Detox-B Stable Emulsion at 0, 2, 5, and 9 weeks. Arm II: Patients receive the control treatment of intravenous cyclophosphamide on day -3, followed by 4 subcutaneous vaccinations with keyhole limpet hemocyanin (KLH) vaccine combined with Detox-B Stable Emulsion at 0, 2, 5, and 9 weeks. Patients with stable or responding disease may receive the THERATOPE STn-KLH vaccine or control without Detox-B Stable Emulsion at weeks 13, 17, 21, and 25. Patients without unacceptable toxic effects or disease progression may continue on maintenance therapy at 3 month intervals.
PROJECTED ACCRUAL: Over 120 sites in North America, Europe, and Australia/New Zealand will be participating in the study. A total of 950 women (475 per treatment arm) will be enrolled into the study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Detox-B adjuvant, THERATOPE STn-KLH vaccine and keyhole limpet hemocyanin in people with Breast Cancer, run by Oncothyreon Canada Inc. at 1 site in Canada.
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 26 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00003638, which also lists 1 linked publication.
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 26 Mar 2013.
