What was measured

PFS was defined as the time from start of study treatment (Cohort A) or date of randomization (Cohort B) to documented disease progression (as determined by BICR per RECIST v1.1) or death from any cause, whichever occurred first. PD was defined as: at least one new malignant lesion, which also included any lymph node that was normal at baseline (\<1.0 cm short axis) and increased to \>=1.0 cm short axis during follow-up or at least a 20% increase in post-baseline sum of the diameters (PBSD) taking as reference the minimum sum of the diameters (MSD). In addition, the PBSD must also demonstrate an absolute increase of at least 0.5 cm from the MSD.

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 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.
