Adjuvant Ribociclib With Endocrine Therapy in Hormone Receptor+/HER2- High Risk Early Breast Cancer (EarLEE-1)

ClinicalTrials.gov Identifier: NCT03078751

Brief Summary:
This is an open label, multi-center protocol for U.S. patients enrolled in a study of ribociclib with endocrine therapy as an adjuvant treatment in patients with hormone receptor-positive, HER2-negative, high risk early breast cancer

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Ribociclib Drug: Adjuvant endocrine therapy Phase 2

Detailed Description:
While adjuvant endocrine therapy (ET) is effective in reducing risk of recurrence in patients with hormone receptor (HR)-positive early breast cancer (EBC), recurrences are still common, especially in patients with unfavorable clinical, pathological and/or molecular features. Ribociclib, a CDK4/6 inhibitor, demonstrated clinical efficacy with tolerable toxicity when added to ET in patients with HR-positive, HER2-negative advanced breast cancer. The purpose of this study is to evaluate the preliminary safety and tolerability of ribociclib to standard adjuvant ET in patients with HR+, HER2- high-risk EBC.
