About this study
Official title: A Phase IIA Trial Assessing the Tolerability of Ribociclib in Combination With an Aromatase Inhibitor in Patients Aged 70 and Older With Hormone Receptor Positive Metastatic Breast Cancer
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.
Read the detailed description
PRIMARY OBJECTIVES:
- 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:
- 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.
- To estimate median progression-free and overall survival.
EXPLORATORY OBJECTIVES:
- 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Grade 2 and Above Toxicities Attributed to Ribociclib
Number of participants with grade 2 and above toxicities attributed (possible, probable or definite) to ribociclib
Measured: Up to 30 days of last study drug, about 3 years and 3 months
Secondary outcomes (5)
Number of Participants With Dose Reductions
Measured: Up to 3.5 years
Number of Participants With Dose Delays
Measured: Up to 3.5 years
Number of Participants With Dose Discontinuations
Measured: Up to 3.5 years
Objective Response Rate by Response Evaluation Criteria in Solid Tumors (RECIST) Criteria
Objective response rate (defined as complete response [CR] + partial response [PR]) as determined by RECIST criteria
Complete Response (CR): Disappearance of all target lesions. Lymph node CR is when the lymph node has decreased to less than 10mm in the short axis.
Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Measured: Up to 3.5 years
Clinical Benefit Rate as Determined by RECIST
Clinical benefit rate (defined as CR+PR+ stable disease) as determined by RECIST
Complete Response (CR): Disappearance of all target lesions. Lymph node CR is when the lymph node has decreased to less than 10mm in the short axis.
Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
Measured: Up to 3.5 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Aromatase Inhibitor, Laboratory Biomarker Analysis and Pharmacokinetic Study in people with Estrogen Receptor and/or Progesterone Receptor Positive and HER2/Neu Negative, run by City of Hope Medical Center at 9 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 33 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 May 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Grade 2 and Above Toxicities Attributed to Ribociclib (time frame: Up to 30 days of last study drug, about 3 years and 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2024.
