SecondaryBest Objective Response as Confirmed By The Investigator's Assessment in Participants With HER2-Expressing Advanced Solid Malignant TumorsBaseline up to disease progression, death, lost to follow up, or study discontinuation (whichever comes first), up to approximately 9 months post-dose
Best objective response (BOR) was assessed by the investigator based on Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. Completed response (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.
SecondaryObjective Response Ratio (ORR) as Confirmed By The Investigator's Assessment in Participants With HER2-Expressing Advanced Solid Malignant TumorsBaseline up to disease progression, death, lost to follow up, or study discontinuation (whichever comes first), up to approximately 9 months post-dose
Objective response ratio (ORR) was defined as the proportion of participants who achieved CR and 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.
SecondaryObjective Response Rate as Confirmed By The Investigator's Assessment in Participants With HER2-Expressing Advanced Solid Malignant TumorsBaseline up to disease progression, death, lost to follow up, or study discontinuation (whichever comes first), up to approximately 9 months post-dose
Objective response rate (defined as participants who achieved CR and PR) was 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. ORR with confirmation is Objective Response Rate applying a confirmed response of CR/PR in RECIST version 1.1.
