Fulvestrant and/or Trastuzumab as First-Line Therapy in Treating Postmenopausal Women With Stage IV Breast Cancer
A Phase 2 study testing Faslodex and Herceptin in people with Breast Cancer, run by Translational Oncology Research International at 3 sites in United States.
Trial summary
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Read more about this study

About this study
Official title: Phase II Randomized Trial of Faslodex and Herceptin, Alone and Combined, in the First - Line Treatment of Hormone Receptor-Positive, HER-2/Neu-Overexpressing Metastatic Breast Cancer
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving fulvestrant together with trastuzumab is more effective than giving fulvestrant or trastuzumab alone in treating breast cancer.
PURPOSE: This randomized phase II trial is studying how well fulvestrant and/or trastuzumab works as first-line therapy in treating postmenopausal women with stage IV breast cancer.
Read the detailed description
OBJECTIVES:
Primary
- Compare the overall objective response rate in postmenopausal women with estrogen receptor (ER)- and/or progesterone receptor (PR)-positive, HER2/neu-overexpressing stage IV breast cancer treated with first-line therapy comprising fulvestrant and/or trastuzumab (Herceptin®).
Secondary
- Compare the duration of response in patients treated with these regimens.
- Compare overall survival of patients treated with these regimens.
- Compare the antitumor activity of these regimens, in terms of time to disease progression, in these patients.
- Compare the clinical benefit of these regimens in these patients.
- Determine the safety and toxicity of these regimens in these patients.
- Correlate HER2/neu expression and ER and/or PR expression with response in patients treated with these regimens.
OUTLINE: This is a randomized, controlled, open-label, multicenter study. Patients are stratified according to prior adjuvant endocrine therapy (yes vs no). Patients are randomized to 1 of 3 treatment arms.
- Arm I: Patients receive fulvestrant intramuscularly on days 1 and 15 of course 1 and then on day 1 only in all subsequent courses.
- Arm II: Patients receive trastuzumab (Herceptin®) IV over 30-90 minutes on days 1, 8, 15, and 22.
- Arm III: Patients receive fulvestrant as in arm I in combination with trastuzumab as in arm II.
In all arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 8 weeks.
PROJECTED ACCRUAL: A total of 120 patients (40 per treatment arm) will be accrued for this study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free Survival
Of the two treated patients on this trial, the records show that one patient who received Herceptin only completed 3 cycles of therapy, while the second patient who received Herceptin in combination with Faslodex completed 9 cycles of therapy. The last survival data collected from October to November 2008 showed that these two participants were alive at that time.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Faslodex and Herceptin in people with Breast Cancer, run by Translational Oncology Research International 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 28 inclusion and 13 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 19 Oct 2020. 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?
Yes. Results are posted in the registry (first posted 11 Feb 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?
Progression-free Survival (time frame: 5 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 19 Oct 2020; AzTrials last refreshed its copy on 7 Nov 2026.
