The prior study used a combination of chemotherapy consisting of carboplatin, paclitaxel and a third targeted anti-cancer drug. In this study the investigators are testing the combination of carboplatin, nano-albumin bound paclitaxel and durvalumab. Nano-albumin bound paclitaxel has been shown to be more active against other types of squamous cancers than regular paclitaxel. It is FDA approved for squamous lung cancer, but experimental for head and neck cancer. Durvalumab is an experimental drug that uses the body's own immune system to fight the cancer. Doctors hope that combining Durvalumab with 2 chemotherapy drugs will be effective in treating SCCHN. Durvalumab on its own has been studied in patients with SCCHN and initial results have shown that some subjects' cancer has responded to it.
