What was measured

cORR was defined as the percentage of participants with confirmed CR or PR according to RECIST v1.1. CR was defined as the disappearance of all target lesions and each target lymph node must have reduction in short axis to less than (\<)1.0 centimeter (cm). PR was defined as at least a 30 percentage (%) decrease in post-baseline sum of the diameters (sum of the longest diameter for all target lesions plus the sum of the short axis of all the target lymph nodes at current evaluation) taking as reference the baseline sum of diameters.

Analysis population: The Full Analysis Set included all participants who were enrolled and received any amount of study treatment and had HER2+ tumors as defined by one or more protocol required local tests. Data for cohort A and B was combined as prespecified in the statistical analysis plan (SAP).

Groups in this outcome

Tucatinib+Trastuzumab (Cohorts A+B)

Participants received Tucatinib 300 mg PO BID on Days 1 to 21 of each 21-day cycle. Trastuzumab 8 mg/kg by IV infusion on Day 1 of Cycle 1 and 6 mg/kg on Day 1 of each subsequent cycle until PD, death, withdrawal of consent, study closure, or alternative therapy.
