Will tarloxotinib finally break the HER2 barrier in lung cancer?
The HER2 gene is a well-known driver of breast cancer, where changes in this gene are found in about 1-in-5 cases of the disease. HER2 also contributes to about 3 percent of lung cancers, representing about 6,500 patients per year. But while drugs like trastuzumab and lapatinib have proven effective in silencing the action of...
