Conditions
Brief summary
This study is designed to provide continued access to intravenous (IV) Herceptin and to evaluate long-term outcomes and overall safety in participants with stable disease and human epidermal growth factor 2 (HER2)-overexpressing metastatic or locally advanced cancer who have completed a prior study with IV Herceptin.
Interventions
Herceptin will be administered as either 2 milligrams per kilogram (mg/kg) once weekly (first dose as a 4-mg/kg loading dose) or 6 mg/kg every 3 weeks (first dose as an 8-mg/kg loading dose) via IV infusion over 90 minutes.

Outcome results
Number of Participants Withdrawn From Study Because of LVEF Dysfunction
LVEF dysfunction was defined as low LVEF measured on two consecutive assessments, with the second assessment performed after 3 weeks of study medication being withheld. Low LVEF included values less than or equal to 39% or values between 40% and 45% (inclusive) with a decrease of 10 or more percentage points from Baseline.
Time frame: From date of enrollment until death or premature withdrawal (maximum 7.4 years of follow-up)
Population: All enrolled participants with available LVEF data were included in the analysis.
