Maria Hafez, MD, spotlights the KATHERINE trial in HER2-positive breast cancer, expanding on the respective toxicity profiles of T-DM1 and trastuzumab that were identified in an exploratory safety analysis of the trial; updated outcomes with T-DM1 in those with residual invasive disease after neoadjuvant treatment and surgery; and more.
The addition of tucatinib to ado-trastuzumab emtansine (T-DM1) significantly improved progression-free survival vs placebo plus T-DM1 in patients with previously treated HER2-positive metastatic breast cancer, including those with brain metastases.
Sara Hurvitz, MD, FACP, shares insights into the results of the HER2CLIMB-02 trial, which saw patients with HER2-positive breast cancer benefit from the addition of tucatinib to trastuzumab emtansine (T-DM1).
