Dr. Gardner [Kenneth G. and Elaine A. Langone Fellow] is studying acquired resistance to targeted therapies in lung cancer. Many targeted therapies used in cancer treatment are capable of controlling disease for a period of time, but in most cases, the disease finds a way to resist or adapt. For instance, some patients treated with epidermal growth factor receptor (EGFR) inhibitors for adenocarcinoma develop resistance to this class of drugs when their cancer transforms to small cell lung cancer (SCLC). Dr. Gardner is investigating this process using both human and mouse models of lung cancer to identify therapeutic approaches that may treat, prevent, or reverse this type of acquired resistance.
