Errors in Affiliations

In the Original Investigation titled “Tucatinib vs Placebo, Both in Combination With Trastuzumab and Capecitabine, for Previously Treated ERBB2 (HER2)-Positive Metastatic Breast Cancer in Patients With Brain Metastases: Updated Exploratory Analysis of the HER2CLIMB Randomized Clinical Trial,”¹ there were errors in the 11th author’s affiliations. Dr Curigliano’s affiliation was “Istituto Europeo di Oncologia, IRCCS, University of Milano, Milan, Italy” but should be “Istituto Europeo di Oncologia, IRCCS, Milano, Italy” and “University of Milano, Milano, Italy.” This article was corrected online.
