Kisqali is indicated for the treatment of women with hormone receptor (HR)positive, human epidermal growth factor receptor 2 (HER2)negative locally advanced or metastatic breast cancer in combination with an aromatase inhibitor or fulvestrant as initial endocrine-based therapy, or in women who have received prior endocrine therapy.

In pre or perimenopausal women, the endocrine therapy should be combined with a luteinising hormonereleasing hormone (LHRH) agonist.
