Triple-negative breast cancer (TNBC) is any breast cancer that either lacks or shows low levels of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) overexpression and/or gene amplification (i.e. the tumor is negative on all three tests giving the name triple-negative). [1]
As of November 2015, there are a number of ongoing and recently completed clinical trials of novel targeted agents for HER2+ metastatic breast cancer, e.g. margetuximab. [36] Additionally, NeuVax (Galena Biopharma) is a peptide-based immunotherapy that directs "killer" T cells to target and destroy cancer cells that express HER2. It has entered ...
Trastuzumab deruxtecan is the first approved therapy by the US Food and Drug Administration (FDA) targeted to people with the HER2-low breast cancer subtype. [4] DNA-based classification. Understanding the specific details of a particular breast cancer may include looking at the cancer cell DNA or RNA by several different laboratory approaches ...
Approximately two of every ten breast cancer diagnoses worldwide are triple-negative. [12] Triple-negative breast cancer is a type of breast cancer that tests negative for estrogen receptors, progesterone receptors and human epidermal growth factor receptor 2 (HER2) protein. [12] Therefore, triple-negative breast cancer does not respond to ...
Buparlisib was under investigation as a treatment for advanced or metastatic HER2-negative breast cancer in several phase III clinical trials: . The phase III trial BELLE-2 compared buparlisib + fulvestrant with fulvestrant alone in patients with advanced or metastatic HER2-negative, hormone receptor-positive (HR+) aromatase inhibitor-resistant breast cancer.
The new Fast Track designation is for advanced or metastatic breast cancer in patients with human epidermal growth factor receptor 2 (HER2) low (IHC 1+ or IHC 2+/ISH–) or HER2-negative (IHC 0 ...
Another receptor that often plays a role in breast cancer, although it is not a hormone receptor, is the human epidermal growth factor receptor 2 (HER2). The overexpression of HER2 is determined by immunohistochemistry (IHC), or with fluorescent in situ hybridization in those equivocal cases where IHC does not provide a clear result.
In the United States, it is indicated for the treatment of adults with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine-based therapy; or fulvestrant as initial endocrine-based therapy or following disease progression on endocrine therapy in ...
