PalbocIclib in PreMenopausal Women With ER Positive/HER-2 Negative MetAstatic Breast Cancer — FATIMA  

Metastatic Breast Cancer Clinical Trial

Official title: A Phase II Study of Ovarian Function Suppression And ExemesTane With or Without PalbocIclib in PreMenopausal Women With ER Positive / HER-2 Negative MetAstatic Breast Cancer

Status Recruiting

Clinical Trial Summary

This is an open label, randomized, multicenter, international phase II study for premenopausal patients with hormone receptor positive, HER2 negative metastatic or locally advanced breast cancer. Patients will be randomized to receive either palbociclib + exemestane + OFS (Arm 1) or exemestane +OFS (Arm 2).

Treatment will be continued until disease progression, unacceptable toxicities, or withdrawal of consent.

Clinical Trial Description

There is a strong in-vitro and clinical evidence suggesting that the dual inhibition of CDK 4/6 and ER signaling is a highly effective therapeutic strategy in HR+ MBC. With the unprecedented success of palbociclib in PALOMA-1 trial, several phase 2 and 3 trials are underway to evaluate this agent (and other CDK4/6 inhibitors as well) in the different clinical scenarios of HR+ breast cancer [28].The vast majority of these trials -if not all- are testing these novel agents in postmenopausal patients, which would render the clinical experience of these agents restricted to postmenopausal women (median age was 62 years in PALOMA-1 trial) The scarcity of clinical trials addressing endocrinal therapy in premenopausal women with MBC is, at least in part, related to the fact that the majority of women in western countries are diagnosed with breast cancer during their postmenopausal life. However the situation is rather different in many countries, including those in the Middle East region, where the median age of women diagnosed with breast cancer is below 50 years, and where approximately 50% of these patients are still menstruating.

This study will be the first to explore the therapeutic effects of palbociclib when combined with exemestane and ovarian function suppression (OFS) in premenopausal with hormone receptor positive and HER2 negative MBC, and how it will compare to the classic approach of using OFS plus an aromatase inhibitor. ;
