About this study
Official title: Phase II Study Of The Trifunctional Bispecific Anti-HER-2/Neu x Anti-CD3 Antibody Ertumaxomab In Patients With HER-2/Neu Overexpressing (3+ Or 2+/FISH+) Metastatic Breast Cancer Progressing After Trastuzumab Treatment
This study has the purpose to demonstrate clinical efficacy of the investigational new drug ertumaxomab in patients with human epidermal growth factor receptor-2 (HER-2/neu) overexpressing (3+ or 2+ with a positive Fluorescence In Situ Hybridization (FISH) test result) metastatic breast cancer progressing after trastuzumab treatment.
Ertumaxomab is a trifunctional bispecific antibody targeting Her-2/neu on tumor cells and CD3 on T cells. Trifunctional antibodies represent a new concept for targeted anticancer therapy. This new antibody class has the capability to redirect T cells and accessory immune effector cells (e.g. macrophages, dendritic cells [DCs] and natural killer [NK] cells) to the tumor site. According to preclinical data, trifunctional antibodies activate these immune cells, which can trigger a complex anti-tumor immune response.
Read the detailed description
This study is an open-label, non-randomized, uncontrolled, two-stage phase II study evaluating the efficacy and safety of ertumaxomab. Ertumaxomab will be administered three times at 7 day intervals by constant rate 3 hour intravenous (i.v.) infusions according to the following dose schedule: 10 µg (day 0); 100 µg (day 7 ± 1 day) and 100 µg (day 14 ± 1 day) (flat doses).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing ertumaxomab in people with Metastatic Breast Cancer and Advanced Breast Cancer, run by Neovii Biotech at 5 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?
The sponsor lists 9 inclusion and 19 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 29 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States, 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 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 29 Apr 2011). 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?
Clinical Efficacy Measured by Objective Response Rate (Best Response During the Course of the Study) (time frame: patients are monitored for 6 months). 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 NCT00522457, which also lists 5 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 29 Apr 2011.
