What was measured

An AE was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A SAE was any AE that met any of the following criteria: fatal (i.e., the AE actually causes or leads to death); life-threatening (i.e., the AE, in the view of the investigator, placed the participant at immediate risk of death); required or prolonged inpatient hospitalization; resulted in persistent or significant disability/incapacity (i.e., the AE results in substantial disruption of the participant's ability to conduct normal life functions); congenital anomaly/birth defect in a neonate/infant born to a mother exposed to study drug; significant medical event in the investigator's judgment.

Analysis population: SE population included all randomized participants who received any amount of study treatment.

Groups in this outcome

Trastuzumab

Participants received trastuzumab, 6 mg/kg, IV, Q3W, as a maintenance dose for 14 cycles (1 cycle = 21 days) or until disease recurrence or unacceptable toxicity which ever occurs first.

Trastuzumab Emtansine

Participants received trastuzumab emtansine, 3.6 mg/kg, IV, Q3W for 14 cycles (1 cycle = 21 days) or until disease recurrence or unacceptable toxicity which ever occurs first.
