Brief Summary:
The purpose of this clinical trial is to study of the molecular features of postmenopausal women with hormone receptor-positive (HR+) HER2-negative advanced breast cancer on first-line treatment with ribociclib and letrozole.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Ribociclib Drug: Letrozole Phase 3

Detailed Description:

The main purpose of this local, multicenter study is to investigate genetic and gene expression alterations in tumor prior to and following progression on ribociclib and thus identify patterns of mutations, how they evolve, and their association with CDK4/6 inhibition and outcomes such as sustained response or early progression. The study also aims to evaluate pharmacogenomics and its association with adverse events (frequency and severity), drug-drug interactions and clinical outcomes.

Finally, the study will also generate additional long-term safety and efficacy data in this specific Italian population.

Primary Outcome Measures :
  1. Change from baseline ctDNA alterations to progression disease [ Time Frame: Up to approximately 36 months ]
    The percentage of patients with ctDNA alterations (i.e. such as but not limited to Rb, ESR1, cyclin D1, CDKN2A, PIK3CA, p53 and PTEN) will be provided over time to characterize the biological evolution of the disease in each patient. The association of these alterations with clinical outcomes will also be provided.


Secondary Outcome Measures :
  1. Change from baseline serum TK1 concentrations to progression disease [ Time Frame: Up to approximately 36 months ]
    Descriptive statistics of serum TK1 concentrations will be provided over time. The association/correlation of serum TK1 concentrations with clinical outcomes will also be provided.

  2. The percentage of patients with ctDNA alterations will be provided over time in the subsets [ Time Frame: Up to approximately 36 months ]
    The percentage of patients with ctDNA alterations will be provided over time in the subsets of long responder patients and those with early progression

  3. Change from baseline tumor mutational burden (TMB) to progression disease [ Time Frame: Up to approximately 36 months ]
    Descriptive statistics of tumor mutational burden (TMB), defined as a quantitative measure of the total number of ctDNA mutations per coding area of tumor genome, will be provided over time, according to the scheduled sample collections. The association of TMB values with clinical outcomes will also be provided.

  4. The percentage of patients with mutations as assessed at baseline across different patient profiles [ Time Frame: Screening ]
    The percentage of patients with mutations as assessed at baseline by means of ctDNA sample, and tissue biopsy will be compared between the following patient profiles defined according to disease history (i.e. newly diagnosed vs. recurrent disease).

  5. The percentage of patients with alterations detected through liquid biopsy vs. tissue biopsy [ Time Frame: Up to approximately 36 months ]
    The percentage of patients with alterations detected at baseline and at disease progression will be compared between the two different procedures of detection (i.e. detection through liquid biopsy vs. tissue biopsy).

  6. Change from baseline tumor microenvironment parameters to progression disease [ Time Frame: Up to approximately 36 months ]
    Descriptive statistics of tumor microenvironment parameters on tumor biopsy will be provided at baseline and upon disease progression. The association of these tumor micro-environment parameters with clinical outcomes will also be provided.

  7. Time-to-Progression (TTP) [ Time Frame: Up to approximately 36 months ]
    Time to progression (TTP) is defined as time from date of start of treatment to the date of event defined as the first documented progression or death due to underlying cancer.

  8. The number of patients with adverse events as a measure of safety and tolerability [ Time Frame: Up to approximately 36 months ]
    Fequency and severity of AEs and SAEs

  9. The percentage of patients with best overall response rate CR or PR [ Time Frame: Up to approximately 36 months ]
    Overall response rate (ORR) is defined as the percentage of patients, with measurable disease, that showed best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1.

  10. The percentage of patients with clinical benefit [ Time Frame: Up to approximately 36 months ]
    Clinical benefit rate (CBR) is defined as the percentage of patients with a best overall response of complete response (CR), or partial response (PR) or an overall lesion response of stable disease (SD), lasting as per local review, for a duration of at least 24 weeks. CR, PR and SD are defined according to RECIST 1.1.

  11. The percentage of participants with adverse events as a measure of safety and tolerability [ Time Frame: Up to approximately 36 months ]
    Frequency and severity of AEs and SAEs

Criteria

Inclusion Criteria:

  • Patient has an advanced (locoregionally recurrent or metastatic) breast cancer in first line treatment (treatment naïve for the advanced setting).
  • Patient is in post-menopause, defined by one of the following:
  • Prior bilateral oophorectomy
  • Age ≥60
  • Age <60 and amenorrhea for 12 or more months (in the absence of chemotherapy, tamoxifen, toremifen, or ovarian suppression) and FSH and estradiol in the postmenopausal range per local normal range
  • Patient has a histologically and/or cytologically confirmed diagnosis of estrogenreceptor positive and/or progesterone receptor positive breast cancer by local laboratory.
  • Patient has an 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 is required by local laboratory testing.
  • Patient is willing to undergo blood and tumor sample collection for the biological assessments/objectives as scheduled in the protocol.

Exclusion Criteria:

  • Patient who received prior treatment with any CDK4/6 inhibitor.
  • Patient who received any prior systemic hormonal therapy or chemotherapy for advanced breast cancer.

Note:

Patients who received neo/adjuvant therapy for breast cancer are eligible. If the prior neo/adjuvant therapy included letrozole or anastrozole, the disease-free interval must be greater than 12 months from the completion of treatment until study entry.

• Patients who received ≤ 28 days of letrozole or anastrozole for advanced disease prior to inclusion in this trial are eligible.

- Patient is currently using other anti-cancer therapy. Other protocol-defined inclusion/exclusion criteria may apply.
