NCT ID: NCT03477396

Last Updated: 2024-02-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 2 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-06-14
• Study Completion Date: 2023-06-05

Brief Summary

This phase IIA trial studies the side effects of ribociclib and aromatase inhibitor and how well they work in treating participants with hormone receptor positive breast cancer that has spread to other places in the body. Ribociclib and aromatase inhibitors may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVES:

I. To estimate the safety and tolerability of the combination of ribociclib and an aromatase inhibitor in adults age 70 or older with hormone receptor positive metastatic breast cancer.

SECONDARY OBJECTIVES:

I. To describe the full toxicity profile including all grades. II. To estimate the rate of worst grades of myelosuppression (neutropenia, leukopenia, thrombocytopenia, and anemia), neutropenic fever, gastrointestinal (GI) side effects (nausea, diarrhea, decreased appetite, vomiting, stomatitis), fatigue, neuropathy, and thromboembolism.

III. To describe rates of dose reductions, dose holds, and hospitalizations. IV. To estimate objective response rate and clinical benefit rate as defined by modified Response Evaluation Criteria in Solid Tumors (RECIST) (1.1) criteria.

V. To estimate median progression-free and overall survival.

EXPLORATORY OBJECTIVES:

I. To estimate the rate of adherence to ribociclib. II. To explore factors other than chronologic age that can affect toxicity rates as identified using a cancer-specific geriatric assessment.

III. To describe the results of the Was It Worth It (WIWI) and the results of the Overall Treatment Utility (OTU) Questionnaires.

OUTLINE:

Participants receive ribociclib orally (PO) once daily (QD) on days 1-21 and aromatase inhibitor per treating investigator's discretion. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up at 30 days, then annually thereafter.

Conditions

Estrogen Receptor and/or Progesterone Receptor Positive; HER2/Neu Negative; Stage IV Breast Cancer AJCC v6 and v7

• First or second line endocrine therapy for metastatic disease. One prior line of chemotherapy for metastatic disease is allowed
• Absolute neutrophil count >= 1.5 x 10^9 /L, at screening
• Platelets >= 100 x 10^9 /L, at screening

• Sodium
• Potassium
• Magnesium
• Total calcium (corrected for serum albumin)
• Phosphorous
• Serum creatinine < 1.5 mg/dL or creatinine clearance >= 50 mL/min, at screening
• In the absence of liver metastases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 2.5 x upper limit of normal (ULN); if the patient has liver metastases, ALT and AST < 5 x ULN, at screening
• Total bilirubin < ULN; or total bilirubin =< 3.0 x ULN or direct bilirubin =< 1.5 x ULN in patients with well-documented Gilbert's syndrome, at screening
• Patient with available standard 12-lead electrocardiogram (ECG) with the following parameters at screening (defined as the mean of the triplicate ECGs):

• Fridericia's corrected QT (QTcF) interval at screening < 450msec (using Fridericia's correction)
• Resting heart rate 50-90 beats per minute (bpm)

Exclusion Criteria

• Patient received prior treatment with any CDK4/6 inhibitor
• Patient has a known hypersensitivity to any of the excipients of ribociclib
