- Primary Outcome Measures
Name Time Method Number of Participants With Best Objective Response Based on Independent Central Review (Confirmed and Unconfirmed) Following DS-8201a Treatment in Participants With Human Epidermal Growth Factor Receptor 2 (HER2)-Expressing Advanced Colorectal Cancer Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to 18 months post-dose Best objective response was reported based on independent central review. As per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1, CR was defined as a disappearance of all target lesions, PR was defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD; at least a 20% increase in the sum of diameters of target lesions.

Duration of response was measured for responding participants (CR or PR) only. Month was calculated as (duration of response days × 12)/365.25 for duration of response and calculated as (time to response days × 12)/365.25 for time to response.
