A Phase IV Study to Collect Data on the Efficacy and Safety of RIBociclib in Older Women With Breastcancer

Korábbi kezelés

• Patients who received any CDK4/6 inhibitor previously.
• Patient who received any prior systemic antihormonal therapy or chemotherapy for advanced breast cancer.
• At least 4 weeks from prior therapy for CNS disease completion (including radiation and/or surgery) to starting the study treatment;
• Clinically stable CNS lesions at the time of study treatment initiation and not receiving steroids and/or enzyme-inducing anti-epileptic medications for the management of brain metastases for at least 2 weeks (radiological confirmation of brain disease status is not necessary).
• 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 study or compromise compliance with the protocol: (e.g. chronic pancreatitis, chronic active hepatitis, active untreated or uncontrolled fungal, bacterial or viral infections, etc.).

Más betegség

• Patient has a known hypersensitivity to any of the excipients of ribociclib or letrozole.
• Patient is concurrently using other systemic anti-cancer therapy (except bone modifying agents).
• with uncontrolled or significant cardiac disease, including recent myocardial infarction, congestive heart failure, unstable angina and bradyarrhythmias;

Laborértékek

• Patients who already have or who are at significant risk of developing QTc prolongation are not eligible for the study. This includes patients:
• with long QT syndrome;
• with electrolyte abnormalities (potassium, magnesium, sodium and calcium) that are NCI CTCAE 4.03 grade 2 or higher (for details, see table 10 ). Note: phosphate testing is not mandatory, but should the investigator consider measuring it before enrolment, the same rules may be applied

Egyéb

• Patient with central nervous system (CNS) metastases and/or documented meningeal carcinomatosis unless they meet ALL the following criteria:

• Patient is a female ≥ 70 years old at the time of informed consent.
• Advanced breast cancer (defined as locoregionally recurrent or metastatic not amenable to curative therapy).
• Histologically and/or cytologically confirmed diagnosis of estrogen-receptor positive and/or progesterone receptor positive breast cancer by local laboratory (defined as ER and/or PgR ≥1% or Allred >2).
• HER2-negative breast cancer defined as a negative in situ hybridization test or an IHC status of 0, 1+ or 2+. If IHC is 2+, a negative in situ hybridization (FISH, CISH, or SISH) test as determined by local laboratory testing according to ASCO-CAP guidelines is necessary.
• Patient has adequate bone marrow and organ function as defined by the following laboratory values (as assessed by local laboratory), preferably tested a maximum of 14 days before enrolment:
• Patient has signed informed consent obtained before any trial-related activities and according to local guidelines.
• Subjects must be able to communicate with the investigator and comply with the requirements of the study procedures.
