1.Primary Outcome
Title Percentage of Participants Experiencing Any Treatment Emergent Adverse Events and Serious Treatment Emergent Adverse Events
Hide Description

Treatment-emergent adverse events (TEAEs) were defined as any adverse events (AEs) that begin or worsen on or after the start of study drug through 30 days after the last dose of study drug. The severity was graded based on the National Cancer Institute's Common Terminology Criteria for Adverse Events Version 4.03. An AE that met one or more of the following outcomes was classified as serious:

  • Fatal
  • Life-threatening
  • Disabling/incapacitating
  • Results in hospitalization or prolongs a hospital stay
  • A congenital abnormality
  • Other important medical events may also be considered serious AEs if they may require medical or surgical intervention to prevent one of the outcomes listed above

Per planned analysis, populations to be used for evaluation of this outcome measure were as follows: Triple Negative Breast Cancer (TNBC) Target Population, HR+/HER2- Metastatic Breast Cancer (mBC) Population, Metastatic Urothelial Cancer (mUC) Population, and Overall Safety Population.

Time Frame First dose date up to last dose (maximum duration: 55.2 months) plus 30 days
