Number of subjects who experienced a maximum severity of Grade 3 or higher post-baseline laboratory abnormality, including either hematology or chemistry. Grades are defined using National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE), version 5.0

Groups in this outcome

Cohort I

Participants with advanced or metastatic biliary tract cancer with HER2 amplification by in situ hybridization (ISH) and HER2 overexpression by immunohistochemistry (IHC) which includes IHC 2+ or 3+

Cohort II

Participants with advanced or metastatic biliary tract cancer with HER2 amplification by ISH and HER2 IHC 0 or 1+.
