Trastuzumab, Gemcitabine, CisplatintrastuzumabParticipants received an initial loading dose of 4 milligrams per kilogram (mg/kg) trastuzumab intravenous (i.v.) on Day 3 of Cycle 1, followed by weekly doses of 2 mg/kg i.v until disease progression; 1200 mg per square meter (m2) gemcitabine i.v. on Days 1, 8, and 15 of Cycles 1 through 6; and 70 mg/m2 cisplatin i.v. on Day 2 of Cycles 1 through 6.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Were Progression Free at 12 and 24 MonthsScreening, and Months 12 and 24
Progression-Free Survival (PFS) - Percentage of Participants With an EventScreening, Day 1 of Cycles 1 through 6, every 4 weeks until end of treatment, up to 33 months

PFS was defined as the time from the first dose of study treatment to the first documentation of objective tumor progression or death due to any cause.

Progression-Free Survival - Time to EventScreening, Day 1 of Cycles 1 through 6, every 4 weeks until end of treatment, up to 33 months

The median time, in months, from the first dose of study treatment to PFS event.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS) - Percentage of Participants With an EventScreening, Day 1 of Cycles 1 through 6, every 4 weeks until end of treatment, up to 36 months

OS was defined as the time from the start of study treatment to date of death due to any cause.

Overall Survival - Time to EventScreening, Day 1 of Cycles 1 through 6, every 4 weeks until end of treatment, up to 36 months

The median time, in months, from the start of study treatment to OS event.

Percentage of Participants Surviving at 12 and 24 MonthsScreening, and Months 12 and 24
Percentage of Participants Achieving Complete Response (CR), Partial Response (PR), or Stable Disease (SD)Screening, Day 1 of Cycles 1 through 6, every 4 weeks until end of treatment, up to 33 months

Per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1): CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must have decreased to normal \[(short axis less than (\<) 10 millimeters (mm)\]. No new lesions. PR was defined as greater than or equal to (≥) 30 percent (%) decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. SD was defined as not qualifying for CR, PR, or Progressive Disease (PD).
