Study Summary

This trial studies how well tucatinib works for solid tumors that make either more HER2 or a different type of HER2 than usual (HER2 alterations) The solid tumors studied in this trial have either spread to other parts of the body (metastatic) or cannot be removed completely with surgery (unresectable). All participants will get both tucatinib and trastuzumab. People with hormone-receptor positive breast cancer will also get a drug called fulvestrant. The trial will also look at what side effects happen. A side effect is anything a drug does besides treating cancer.

Primary Outcome

Confirmed ORR was defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria version (v)1.1 as assessed by investigator and was considered as confirmed when subsequent response was at least 4 weeks after initial response. As per RECIST v1.1, CR: disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction
