• Submission of a representative tumor specimen that is suitable for next-generation sequencing (NGS) testing and estrogen receptor immunohistochemistry (ER IHC) to determine treatment arm assignment and for central pathology review.
• Submission of the local pathology report and, if available, any associated stained slides that supported the local diagnosis of the histology (to be used for central pathology review)
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
• Adequate hematologic and end-organ function
• For women of childbearing potential: agreement to remain abstinent or use contraception, and agreement to refrain from donating eggs (if applicable)
