- Pfizer
- Brief Summary
The goal of this study is to evaluate the efficacy and safety of tucatinib in combination with trastuzumab and capecitabine in participants with unresectable locally advanced or metastatic HER2+ breast cancer who have had prior treatment with taxane anti-cancer agent, trastuzumab, pertuzumab and trastuzumab emtansine (T-DM1). The primary hypothesis is that the confirmed objective response rate (cORR) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) as determined by independent central review (ICR) for the combination of tucatinib, trastuzumab and capecitabine, is greater than 20%.

- Primary Outcome Measures
Name Time Method Confirmed Objective Response Rate(cORR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 Determined by Independent Central Review (ICR): Japanese Participants From date of first dose until first documented disease progression or start of new anticancer therapy, whichever occurred first (maximum up to 17.8 months) cORR was defined as percentage of participants with confirmed complete response (CR) or partial response (PR), per RECIST version 1.1. CR: disappearance of all target lesions. Any pathological lymph nodes must have a reduction in short axis to \<10 millimeter(mm). PR: a \>=30% decrease in the sum of diameters of target lesions, taking as a reference the baseline sum diameters. Only response assessments before first documented progressive disease(PD) or new anti-cancer therapies were considered. PD: at least a 20% increase in sum of diameters of target lesions, taking as reference the smallest sum on study(included baseline sum if smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Appearance of one or more new lesions was also considered PD. Participants with missing data were considered non-responders. cORR was determined by ICR. Two-sided 90% exact confidence interval was based on Clopper-Pearson method.
