MOLECULARLY TARGETED: HER2/ERBB2 amplification or mutation: myTACTIC Arms F/G/H/I

myTACTIC: An open-label Phase II study evaluating targeted therapies in patients who have advanced solid tumors with genomic alterations or protein expression patterns predictive of response: Arm F: Trastuzumab emtansine plus atezolizumab   Arm G: PH FDC SC  Arm H: PH FDC SC plus chemotherapy Arm I: trastuzumab emtansine plus tucatinib, in patients with ERBB2 gene amplification- or mutation-positive tumors.
