Study Endpoints

Primary Endpoints

Progression Free Survival (PFS) at the Time of Primary Results
From date of randomization until date of progression or date of death from any cause, whichever comes first, assessed up to approximately 39 months

Progression-free survival (PFS) is the time from randomization to the earliest date of RECIST 1.0 assessment of disease progression (with radiological evidence), death from any cause, or censoring. Disease progression was assessed by the Investigator and defined by RECIST v1.0 as a 20% increase in the sum of the longest diameter of target lesions, a measurable increase in a non-target lesion, or the appearance of new lesions.

Secondary Endpoints

Progression Free Survival (PFS) at the Time of Final Analysis
From date of randomization until date of progression or date of death from any cause, whichever comes first, assessed up to approximately 45 months
Overall Survival (OS) (IIT Population)
From date of randomization until date of death from any cause, assessed up approximately 165 months
Overall Survival (OS) (Central HER2+ Population)
From date of randomization until date of death from any cause, assessed up approximately 165 months
