epirubicin.
- Patient with a known hypersensitivity to any of the excipients of ribociclib and/or ET - Patient with distant metastases of breast cancer beyond regional lymph nodes (stage IV according to AJCC 8th edition) and/or evidence of recurrence after curative surgery.
- Patient is concurrently using other anti-neoplastic therapy with the exception of adjuvant ET
- Patient has had major surgery, chemotherapy or radiotherapy within 14 days prior to randomization

- Patient has a concurrent invasive malignancy or a prior invasive malignancy whose treatment was completed within 2 years before randomization
- Patient has known HIV infection, Hepatitis B or C infection
- Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality
- Patient is currently receiving any of the following substances within 7 days before randomization - Concomitant medications, herbal supplements, and/or fruits that are known as strong inhibitors or inducers of CYP3A4/5 or Medications that have a narrow therapeutic window and are predominantly metabolized through CYP3A4/5
- is currently receiving or has received systemic corticosteroids ≤ 2 weeks prior to starting trial treatment
- Patient has impairment of GI function or GI disease that may significantly alter the absorption of the oral trial treatments
- Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the Investigator's judgment, cause unacceptable
safety risks, contraindicate patient participation in the clinical trial or compromise compliance with the protocol
- Participation in other studies involving investigational drug(s) within 30 days prior to randomization or within 5 half-lives of the investigational drug(s) (whichever is longer), or participation in any other type of medical research judged not to be scientifically or medically compatible with this trial. If the patient is enrolled or planned to be enrolled in another study that does not involve an investigational drug, the agreement of the Medical Monitor is required to establish eligibility.
- Pregnant or breast-feeding (lactating) women or women who plan to become pregnant or breast-feed during the trial.
additional exclusion criteria as per full protocol may apply. |
