Description of intervention(s) / exposure
Treatment: Drugs - Herceptin
Treatment: Drugs - Herceptin

No intervention: Observation Arm - Participants who have completed definitive surgery and systemic adjuvant chemotherapy will be observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant. No Herceptin will be provided.

Experimental: Herceptin 1-Year Arm - Participants who have completed definitive surgery and systemic adjuvant chemotherapy will receive Herceptin for 1 year or until disease recurrence, whichever occurs first. Participants will be observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant.

Experimental: Herceptin 2-Year Arm - Participants who have completed definitive surgery and systemic adjuvant chemotherapy will receive Herceptin for 2 years or until disease recurrence, whichever occurs first. Participants will be observed for efficacy and safety until 10 years from individual randomization and for survival until 10 years after enrollment of the last participant.


Treatment: Drugs: Herceptin
Herceptin will be given as a loading dose of 8 milligrams per kilogram (mg/kg) via intravenous (IV) infusion on Day 1, followed by a maintenance dose of 6 mg/kg via IV infusion 3 weeks later and thereafter every 3 weeks.

Treatment: Drugs: Herceptin
Herceptin will be given as a loading dose of 8 mg/kg via IV infusion on Day 1, followed by a maintenance dose of 6 mg/kg via IV infusion 3 weeks later and thereafter every 3 weeks.

Summary
Brief summary
The purpose of this trial is to evaluate Herceptin treatment for 1 year and 2 years (versus observation/no Herceptin) in women with HER2-overexpressing primary breast cancer who have completed (neo-)adjuvant systemic chemotherapy, definitive surgery, and radiotherapy, if applicable. Efficacy and safety will be assessed for 10 years from randomization for each participant. All participants will continue to be followed for survival until 10 years after enrollment of the last participant.
