The FDA has approved fulvestrant (Faslodex) for use in combination with the CDK4/6 inhibitor abemaciclib (Verzenio) to treat patients with HR+/HER2- advanced or metastatic breast cancer who have progressed after endocrine therapy.
The FDA approved single-agent fulvestrant in August 2017 for postmenopausal women with HR+/HER2- advanced breast cancer who have not received previous endocrine therapy. The drug had previously been approved as a single agent for HR+ patients following progression on endocrine therapy, and in combination with palbociclib (Ibrance) for the treatment of women with HR+/HER2-negative advanced or metastatic breast cancer who progressed following endocrine therapy.
