Summary
Brief summary
This is a Phase II, multicenter, open-label, randomized study to compare the efficacy of
venetoclax in combination with fulvestrant compared with fulvestrant alone in women with ER+,
HER2-negative, locally advanced or Metastatic Breast Cancer (MBC) who experienced disease
recurrence or progression during or after treatment with CDK4/6i therapy for at least 8
weeks. As of 9th October 2020, participants in the Venetoclax + Fulvestrant arm, have all
discontinued Venetoclax treatment and have continued on Fulvestrant treatment alone.
