Study comparing two standard treatments as initial metastatic treatment among patients with visceral metastasis of ER+ HER2- breast cancer, high burden disease: chemotherapy and combination of hormonotherapy with abemaciclib.
EU CTIS ID: 2024-513005-31-00
What this study is testing
The primary objective is to compare the efficacy of standard Endocrine Therapy + Abemaciclib combination versus standard Chemotherapy based on progression-free survival (PFS), in patients with visceral metastases of ER+ HER2- breast cancer, high tumor burden.

Who can take part
You may be able to join if
- Patient must have signed a written informed consent form prior to any study specific procedures
- ER-positive by IHC (>10%) on primary or metastatic disease
- HER2-negative by IHC (score 0 or 1+) and/or Fish/Cish negative
- Non-menopausal women will receive LH-RH agonists before starting the endocrine therapy and every 28 days thereafter. It is recommended that LHRH agonist therapy be started approximately 28 days before the start of hormone therapy
- Adequate renal, hepatic, and hematopoietic functions as defined by the following criteria: Absolute Neutrophil Count (ANC) ≥ 1,500/mm3 or ≥ 1.5 G/L
- Adequate renal, hepatic, and hematopoietic functions as defined by the following criteria: Platelets ≥ 100,000/mm3 or ≥ 100 G/L
You likely can't join if
- Bone lesion only or non-measurable lesion (RECIST V1.1)
- Previous or current malignancies of other histologies within the last 5 years, with the exception of in situ carcinoma of the cervix or the breast, and adequately treated basal cell or squamous cell carcinoma of the skin
- Patient has active systemic bacterial infection (requiring intravenous [IV] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C [for example, hepatitis B surface antigen positive]. Screening is not required for enrollment
- Patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest
- Patient has any serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment [e.g. estimated creatinine clearance < 30 mL/min], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn’s disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea)
- Any drug or plant derivative that may interact with abemaciclib
