About this study
Official title: A National Phase IIIb, Multi-center, Open Label Study for Women and Men With Hormone-receptor Positive, HER-2 Negative Locally Advanced or Metastatic Breast Cancer Treated With Ribociclib (LEE011) in Combination With Letrozole
This was a national, multi-center, open-label, phase IIIb trial to determine the efficacy and safety of treatment with ribociclib (LEE011) plus letrozole in patients with HR+, HER2-negative advanced (recurrent or metastatic) breast cancer. Patients were treated with daily doses of 600 mg ribociclib (3-weeks-on/1-week-off schedule) in combination with 2.5 mg letrozole daily (continuous dosing). Dose adjustments (dose reduction or interruption) according to safety findings were allowed.
Read the detailed description
The main purpose of this study was to collect additional efficacy and safety data for the combination of ribociclib and letrozole in a patient population broader than the MONALEESA-2 study (NCT01958021 / CLEE011A2301), and to provide access to ribociclib to patients for which available treatment options are unsatisfactory treatment alternatives until the drug is approved for this indication. Furthermore, this trial aimed to collect data for the combination of ribociclib and letrozole in the context of current local routine therapy algorithms for the treatment of metastatic and advanced breast cancer.
This multi-center, open-label, single-arm study aimed to evaluate the efficacy, safety, and quality of life for the combination of ribociclib and letrozole in a patient population than in the MONALEESA-2 study, i.e. in patients pretreated with one line of chemotherapy and/or a maximum of two lines of endocrine therapy as well as premenopausal patients, without limitations regarding the disease free interval after adjuvant therapy.
For ethical reasons no endocrine comparator drugs were investigated in this study. The duration of study treatment of 80 weeks was adequate to determine the primary, secondary and exploratory study parameters. The sample size was suitable to estimate the clinical benefit rate (CBR) in this patient population with reasonable precision.
Goserelin was used in premenopausal patients, since it was shown that ovarian suppression of estrogen release with luteinizing hormone-releasing hormone agonists (LHRHa) (such as goserelin) is effective in preventing relapse in premenopausal women with early stage ER+ breast cancer (Klijn et al. 2001).
The efficacy and safety of ribociclib in combination with letrozole for the treatment of postmenopausal women with advanced or metastatic breast cancer vs. placebo (i.e., letrozole alone) was already demonstrated in the preceding, pivotal MONALESSA-2 study. Thus, for ethical reasons no endocrine comparator drugs were investigated in the present RIBECCA study.
Generally, the single-arm, open-label design and the broadening of the study population (compared to the pivotal MONALESSA-2 study) in the RIBECCA study was deemed appropriate to further evaluate the efficacy and safety of ribociclib plus letrozole among breast cancer patients in a treatment setting closer to routine care. The duration of study treatment of up to 80 weeks was considered adequate to determine the primary, secondary and exploratory study parameters. Moreover, the sample size was suitable to estimate the CBR in this patient population with reasonable precision.

What is being measured
The primary outcome is the main question the study is designed to answer.
Clinical Benefit Rate (CBR) in Women and Men With Hormone Receptor Positiv, HER-2 Negative Breast Cancer Treated With Ribocilib and Letrozole
Clinical Benefit Rate (CBR) after 24 weeks of treatment as defined by RECIST 1.1 as percentage of patients with Complete Response (CR), Partial response (PR) or Stable disease (SD) lasting 24 weeks or longer as well as patients with Non-complete response, nonprogressive disease (NCRNPD).
Measured: At 24 weeks after last patient enrolled in trial
Secondary outcomes (10)
Progression Free Survival (PFS) for Different Populations - Kaplan-Meier Estimates (%, 95% CI)
PFS based on radiologic assessment by investigator using RECIST 1.1 criteria
Measured: At week 24 , week 48 and week 72
Progression Free Survival (PFS) for Different Populations - Median Time to Progression or Death With 95% CI [Months]
PFS based on radiologic assessment by investigator using RECIST 1.1 criteria
Measured: Up to approximately month 25
Overall Survival (OS) - Kaplan-Meier Estimates (%, 95% CI)
Overall survival (OS) defined as the time from date of start of treatment to date of death due to any cause. For the Kaplan-Meier estimates (%, 95% CI), the probability of survival at week 24, 48 and 72 is reported below.
Measured: At Week 24, Week 48 and Week 72

Change From Baseline at Week 24 of Patient Reported Quality of Life (QoL) Via EORTC QLQ-C30
The QLQ-C30 is the core questionnaire of the EORTC QLQ, which has been developed for the assessment of the health-related QOL of cancer patients participating in international clinical trials. Using a linear transformation to standardize the raw scores, all scores finally range from 0 to 100, where a higher score represents a higher response level, e.g., a higher ("better") level of functioning (applies to the first 6 items, items 1 to 6), but a higher ("worse") level of symptoms (applies to the last 9 items, items 7 to 15). There is no aggregated total score, i.e., all scale scores were analyzed separately.
Measured: Change from Baseline to Week 24
Patient Reported Quality of Life (QoL) Via EORTC BR-23 - Change From Baseline at Week 24 (Cycle 7)
To evaluate health related quality of life (QoL) via EORTC BR-23. The scoring approach for the QLQ-BR23 is identical in principle to that for the function and symptom scales / single items of the QLQ-C30, i.e., all scores finally range from 0 to 100, where a higher score represents a higher response level, e.g., a higher ("better") level of functioning, (applies to the first 4 items, items 1 to 4) but a higher ("worse") level of symptoms (applies to the last 4 items, items 5 to 8).
Measured: Baseline and Week 24 (Cycle 7)

Time to 10% deterioration in the European Organisation for Research and Treatment of Cancer (EORTC) global health status
Measured: up to approximately 10 months
Number of Participants With Treatment Emergent Adverse Events (TEAE)
Adverse Events (AEs) were separated into TEAEs (defined as AEs occurring/worsening from first study drug treatment until 30 days after the last study drug treatment) and AEs in the pre-/post-treatment period.
Measured: Up to Week 72

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?
Clinical Benefit Rate (CBR) in Women and Men With Hormone Receptor Positiv, HER-2 Negative Breast Cancer Treated With Ribocilib and Letrozole (time frame: At 24 weeks after last patient enrolled in trial). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03096847, which also lists 1 linked publication.
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.
