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.
Trastuzumab administered subcutaneously delivered unique immunomodulation effects vs intravenous trastuzumab in patients with treatment-naïve HER2-positive (HER2+) breast cancer
Adjuvant ado-trastuzumab emtansine continued to improve overall survival and invasive disease-free survival vs trastuzumab after 8.4 years of follow-up in patients with HER2-positive early breast cancer and residual invasive disease following neoadjuvant therapy enrolled in the phase 3 KATHERINE trial.
