What was measured

Individual steady state predicted exposure, as assessed by median AUC (measured as mg multiplied by \[\*\] day per liter \[L\]) calculated for all treated participants using the nominal dosage schedule administered as an IV infusion. Individual steady state AUC was calculated using all available PK samples from all timepoints.

Analysis population: Pharmacokinetic (PK) population: all participants with at least 1 measurement of trastuzumab serum concentration associated with a documented trastuzumab dosing history.

Groups in this outcome

Trastuzumab + Fluoropyrimidine/Cisplatin (FP + H)

Participants received trastuzumab plus fluoropyrimidine (EITHER 5-FU or capecitabine, at the investigator's discretion) and cisplatin once every 3 weeks (one cycle) for a maximum of 6 cycles (except as noted) as follows: trastuzumab 8 mg/kg, IV, on Day 1 (Cycle 1), followed by 6 mg/kg, IV (Cycles 2 onward, administered until disease progression); cisplatin 80 mg/m\^2 IV on Day 1; and EITHER 5-FU 800 mg/m\^2 continuous IV infusion on Days 1 through 5 OR capecitabine 1000 mg/m\^2 tablets, PO BID from the evening of Day 1 through the morning of Day 15.
