Patients with an excessive number of the HER2 protein or amplification of the gene will see benefit from treatment with trastuzumab, Mittendorf says.
Clinical Pearls
The E75 vaccine is a piece of the HER2 protein and is the best peptide with respect to presentation by antigen-presenting cells to be shown to T cells. E75 fits well into the HER2 story, Mittendorf says, as it is effective in patients with any degree of HER2 expression. For the vaccine to be effective, the immune system simply needs to recognize any amount of HER2.
