Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Objective Response Rate Based on The Investigator's Assessment (Unconfirmed) Following DS-8201a Treatment in Participants With HER2-expressing Metastatic and/or Unresectable Breast Cancer
Time Frame: Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to 12 months post-dose
Objective response rate (ORR) was defined as unconfirmed complete response (CR) and partial response (PR) as assessed by the investigator based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. CR was defined as a disappearance of all target lesions and PR was defined as at least a 30% decrease in the sum of diameters of target lesions.
Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to 12 months post-dose
Objective Response Rate Based on The Investigator's Assessment (Unconfirmed) Following DS-8201a Treatment in Participants With HER2-expressing Metastatic and/or Unresectable Breast Cancer
Time Frame: Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to 38 months post-dose
Objective response rate (ORR) was defined as unconfirmed complete response (CR) and partial response (PR) as assessed by the investigator based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. CR was defined as a disappearance of all target lesions and PR was defined as at least a 30% decrease in the sum of diameters of target lesions.
Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to 38 months post-dose

Time Frame: Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to approximately 12 months post-dose
Adverse events (AEs) were to be coded using MedDRA Version 20.1 and assigned severity grades based on Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03. A treatment-emergent adverse event (TEAE) was defined as an AE that occurred, having been absent before the first dose of study drug, or had worsened in severity or seriousness after initiating the study drug until 47 days after last dose of study drug.
Baseline up to withdrawal of consent, progressive disease, or unacceptable toxicity (whichever occurs first), up to approximately 12 months post-dose
