About this study

The aim of this study is to analyze cases of human epidermal growth factor receptor (HER) 2-positive metastatic breast cancer (MBC) of the last 10 years at the University Hospital of Zurich to assess the efficacy of the treatment with trastuzumab in HER2-positive MBC and to find out associations between different variables and the outcome. The aim is to find out probable prognostic factors and patterns of disease progression. Prognostic factors could optimize treatment approaches and result in a delay of disease progression.

Read the detailed description

Human epidermal growth factor (HER2) is a receptor tyrosine kinase and regulates diverse functions in normal cells such as growth, differentiation and survival of cells. In 25-30 per cent of breast cancer HER2 gene is amplified, what result in abnormally high levels of encoded HER2 protein in malignant cells. Overexpression or amplification of HER2 is associated with an aggressive form of breast cancer seen by significantly shortened disease-free survival and overall survival.

Trastuzumab, a humanized monoclonal antibody against the extracellular domain of HER2, inhibits the growth of breast tumor cells by receptor internalization, inhibition of cell-cycle progression and recruitment of immune-effector cells. Trastuzumab, as the first anti-HER2 therapy, is approved since 1998 in the United States and since 2000 in European countries for the treatment of HER2-overexpressing metastatic breast cancer (MBC). Single therapy as well as combination with chemotherapy has significantly improved the outcome of these women. Shown by longer time to disease progression, longer duration of response, lower rate of death at 1 year, longer survival and a 20 per cent reduction in the risk of death.

But still is little known about the long-term outcome nor patterns of disease progression of HER2-positive MBC. A few case reports showed a prolonged complete remission in HER2-positive MBC under an anti-HER2 treatment (trastuzumab, T-DM1, pertuzumab). These cases had some common characteristics such as negative hormone receptor status and metastasis to the live. Another hypothesis is a worse prognosis for patients with early development of CNS metastases.

Questions about this trial

What is this clinical trial studying?

An observational study of ERBB2 and Breast Cancer, run by University of Zurich at 1 site in Switzerland.

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 2 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 25 Sep 2015. 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 Switzerland. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Konstantin J Dedes, Dr.med. (+41 44 255 11 11, konstantin.dedes@usz.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to disease progression (time frame: up to 120 months). 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 25 Sep 2015.
