Analysis population: Adverse events were assessed in the Safety Analysis 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.
Exploratory: Naïve HER2 IHC 2+/ISH-, DS-8201a
Non-randomized participants with HER2 IHC 2+/ISH- advanced gastric or gastroesophageal junction adenocarcinoma who received DS-8201a once every three weeks.
Exploratory: Naïve HER2 IHC 1+, DS-8201a
Non-randomized participants with HER2 IHC 1+ advanced gastric or gastroesophageal junction adenocarcinoma who received DS-8201a once every 3 weeks.
