Primary Outcome Measures
NameTimeMethod
Main Objective: To determine the objective response rate (ORR) of DS-8201a in HER2-expressing advanced metastatic colorectal cancer patients;Secondary Objective: •To evaluate duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). ORR assessed by the investigator is also evaluated.<br>•To evaluate the safety of DS-8201a<br>•To determine the pharmacokinetics (PK) of DS-8201a;Primary end point(s): Objective response rate (ORR) per imaging assessment - Percentage of participants with objective response per independent central imaging<br>facility review based on Response Evaluation Criteria In Solid Tumors<br>(RECIST) version 1.1;Timepoint(s) of evaluation of this end point: every 6 weeks
