An open-label, multicenter, Phase IIIb study to assess the safety and efficacy of ribociclib (LEE011) in combination with letrozole for the treatment of men and pre/postmenopausal women with hormone receptor-positive (HR+) HER2 negative (HER2-) advanced breast cancer (aBC) with no prior hormonal therapy for advanced disease

An open-label, multicenter, Phase IIIb study to assess the safety and efficacy of ribociclib (LEE011) in combination with letrozole for the treatment of men and pre/postmenopausal women with hormone receptor-positive (HR+) HER2 negative (HER2-) advanced breast cancer (aBC) with no prior hormonal therapy for advanced disease

This open-label, single arm, multi-center Phase IIIb study will evaluate the overall
safety and tolerability and clinical efficacy of ribociclib in combination with letrozole in men and pre/postmenopausal women with HR+, HER2- aBC and no prior hormonal treatment for advanced disease. A total of approximately 3,000 patients will be enrolled for treatment with Letrozole (2.5 mg once daily) + Ribociclib (LEE011) 600 mg (day 1 to 21 in a 28 day cycle); goserelin (3.6mg as injectable subcutaneous implant every 28 days) will be used in men and premenopausal women patients. Patients will receive trial treatment until disease progression, death, unacceptable toxicities, physician’s decision, subject/guardian’s decision, protocol deviation, study termination by sponsor, lost to follow-up, technical problems or until 24 months after LPFV whichever event occurs first.
