It's considered a targeted therapy, an EGFR monoclonal antibody, but is still "referred " to as chemo sometimes, I do, just to save explaining. It's been around for a while, since the early 90's for colon cancer, but didn't get approval by the FDA, and stocks were dumped by Imclone big wigs, and reason why Martha Stewart went to jail for insider trading, but it had geen since was taken over, and approved, and approved for metastic HNC, and later for first line therapy. I had it in 2012 along with Taxotere. Its doesnt work in about 5% of HNC patients, but there is no assay, unlike colon/rectal, there is, and doesn't work in 40% of colon cancers who have a muted KRAS protein. The main side effect is the facial rash, which is consiered the drug to the to be working, and rarely, is an allergic reaction, cardiac arrest, which can be deadly. There is an ongoing clinical trails with Erbitux vs Cisplatin that is not completed yet. You can use the search to see the previous discussions, abstracts, some which I posted. I've seen some that say its just ad good as cisplatiin, and some, maybe not.
