What was measured
The Objective Response Rate (ORR) is the percentage of participants who achieved a best overall response of Complete Response (CR) or Partial Response (PR), assessed by Investigator based on RECIST version 1.1. The best overall response is the best overall response (BOR) recorded from the start of the study treatment until the end of treatment and includes CR, PR, stable disease (SD), progressive disease (PD) and not evaluable (NE) as assessed by Investigator based on 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 SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD (at least a 20% increase in the sum of diameters of target lesions). Unconfirmed ORR and BOR (not confirmed by Investigator) and confirmed ORR and BOR (confirmed by Investigator) are reported.
Analysis population: Objective response rate (ORR) and best overall response (BOR) were assessed in the Response Evaluable Set.
Groups in this outcome
DS-8201a
Participants with HER2-overexpressing (IHC 3+ or IHC 2+/ISH+) advanced gastric or gastroesophageal junction adenocarcinoma, whose disease had progressed on two prior regimens, were randomized to receive DS-8201a once every 3 weeks.
Physician's Choice Irinotecan
Participants with HER2-overexpressing (IHC 3+ or IHC 2+/ISH+) advanced gastric or gastroesophageal junction adenocarcinoma, whose disease had progressed on two prior regimens, were randomized to receive irinotecan monotherapy as prescribed by the physician before enrollment.
Physician's Choice Paclitaxel
Participants with HER2-overexpressing (IHC 3+ or IHC 2+/ISH+) advanced gastric or gastroesophageal junction adenocarcinoma, whose disease had progressed on two prior regimens, were randomized to receive paclitaxel monotherapy as prescribed by the physician before enrollment.
Physician's Choice Overall
Participants with HER2-overexpressing (IHC 3+ or IHC 2+/ISH+) advanced gastric or gastroesophageal junction adenocarcinoma, whose disease had progressed on two prior regimens, were randomized to receive either irinotecan or paclitaxel monotherapy as prescribed by the physician before enrollment.
