- Registration Number
- NCT00448305
- Lead Sponsor
- MediGene
- Brief Summary
The purpose of this study is to assess the efficacy, safety and tolerability of a therapy with EndoTAG-1 + paclitaxel in combination and EndoTAG-1 alone as a rescue therapy for patients with relapsed or metastatic triple receptor negative breast cancer (a special subgroup of breast cancer).
- Detailed Description
Breast cancer is still a major public health problem worldwide, as it is by far the most frequent neoplasm in women. In recent years so-called "profiling of breast cancer" with expression arrays has become common and it was suggested that the results will allow individualization of care. Breast cancer may now be subclassified into luminal, basal, and HER-2 subtypes with distinct differences in prognosis and response to therapy. About 80% of all basal-like-breast cancers possess a so-called "triple-receptor-negative" phenotype.
Patients with "triple receptor negative breast cancer" have a complete absence of hormone receptors incl. HER-2, an aggressive clinical course and a paucity of treatment options. The only therapeutic option is chemotherapy and in this respect the choice of cytostatic agents is limited. Against this background, the study tries to find another therapeutic option by combining a vascular-disrupting activity with the cytostatic effects of paclitaxel in the study drug EndoTAG-1.
Comparison: EndoTAG-1 + paclitaxel (combination therapy) and EndoTAG-1 (monotherapy) in comparison to paclitaxel (control group)
