  • 2. Has radiographic disease progression on one or more lines of endocrine therapy for unresectable locally advanced/metastatic HR+/HER2- breast cancer, with one in combination with a CDK4/6 inhibitor.
  • 3. Is a chemotherapy candidate
  • 4. Has an eastern cooperative oncology group (ECOG) performance status of 0 to 1 assessed within 7 days before randomization

You likely can't join if

  • 1. Has breast cancer amenable to treatment with curative intent
  • 2. Has experienced an early recurrence (<6 months after completing adjuvant/neoadjuvant chemotherapy) and therefore is eligible to receive second-line (2L) treatment
  • 3. Has symptomatic advanced/metastatic visceral spread at risk of rapidly evolving into life-threatening complications
  • 4. Has received prior chemotherapy for unresectable locally advanced or metastatic breast cancer
  • 5. Active autoimmune disease that has required systemic treatment in the past 2 years
