Another monoclonal antibody, Pertuzumab, which inhibits dimerisation of HER2 and HER3 receptors, was approved by the FDA for use in combination with trastuzumab in June 2012. 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 .
Cells with none of these receptors are called basal-like or triple negative. HER2-low has some HER2 proteins on the cell surface, but not enough to be classified as HER2-positive. [4] 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]
Trastuzumab deruxtecan is indicated for the treatment of adults with unresectable (unable to be removed with surgery) or metastatic (when cancer cells spread to other parts of the body) HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting and for adults with locally advanced or metastatic HER2-positive gastric or gastroesophageal ...
The HER2 gene (also known as HER2/neu and ErbB2 gene) is amplified in 20–30% of early-stage breast cancers. [44] Trastuzumab is a monoclonal antibody targeting HER2, inducing an immune-mediated response that causes internalization and recycling of HER2. It may also upregulate cell cycle inhibitors such as p21 Waf1 and p27 Kip1. [58]

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).

Stocks pulled back Friday morning as bond yields reached higher. Mixed initial jobless claims data sent the 10-year Treasury yield to a seven-month high on Thursday.
Trastuzumab is the anti-HER2 antibody; emtansine refers to the linker-drug (SMCC-DM1). The "ado-" prefix was added at the request of the FDA to help prevent dispensing errors . [ 31 ] [ 20 ] [ 32 ] During preclinical development and clinical trials, the drug was also known as trastuzumab-DM1 or trastuzumab-MCC-DM1 (after the codename for ...
