NCT01958021

Brief Summary

The primary purpose of this study was to assess the efficacy of ribociclib, as measured by progression free survival (PFS), in postmenopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer who received no prior treatment for advanced disease.

Outcome Measures

Primary Outcomes (1)

  • Progression Free Survival (PFS) by Investigator Assessment

    PFS was defined as the period starting from the date of randomization to the date of the first documented progression or death caused by any reason. In cases where patients did not experience an event, the PFS was censored at the date of the last adequate tumor assessment. Clinical deterioration without objective radiological evidence was not considered as documented disease progression.PFS was assessed by investigator assessment according to RECIST 1.1. The Kaplan-Meier method was used to estimate PFS, and the median PFS, along with 95% confidence intervals, was reported for each treatment group. A stratified Cox regression model was used to estimate the hazard ratio of PFS, along with 95% confidence interval

    Up to 23 months

Secondary Outcomes (6)

  • Overall Survival (OS)

    Up to approximately 87 months

  • Overall Response Rate (ORR) by Investigator Assessment

    Up to 23 months

  • Clinical Benefit Rate (CBR) by Investigator Assessment

    Up to 23 months

  • Time to Definitive Deterioration of Eastern Cooperative Oncology Group Performance Status (ECOG PS) by at Least One Category of the Score

    From baseline up to 23 months

  • Time to Definitive 10% Deterioration in the Global Health Status/Quality of Life (GHS/QoL) Scale Score of the European Organization for Research and Treatment of Cancer's Core Quality of Life Questionnaire (EORTC QLQ-C30)

    From baseline up to 23 months

  • +1 more secondary outcomes

Study Arms (2)

Ribociclib+ letrozole

EXPERIMENTAL

Ribociclib 600 mg daily oral (3 weeks on/ 1 week off) in combination with letrozole 2.5 mg daily oral

Drug: RibociclibDrug: Letrozole

Placebo + letrozole

PLACEBO COMPARATOR

Placebo daily oral (3 weeks on/ 1 week off) in combination with letrozole 2.5 mg daily oral. Participants were unblinded once the final OS analysis was completed and after the implementation of protocol amendment 10 (30-Apr-21) and were given the option to crossover to treatment with ribociclib + letrozole

Drug: LetrozoleDrug: Placebo

Interventions

Ribociclib (600 mg, in three 200 mg hard gelatin capsules or tablets) was administered orally once daily on Days 1-21 of each 28-day cycle.

Also known as: LEE011
Ribociclib+ letrozole

Letrozole (2.5 mg, tablets) was administered orally once daily on a continuous daily schedule (days 1-28 of each 28-day cycle)

Placebo + letrozoleRibociclib+ letrozole

Placebo (hard gelatin capsules or tablets) was administered orally once daily on Days 1-21 of each 28-day cycle.

Placebo + letrozole

Eligibility Criteria

Age18 Years - 100 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women with advanced (locoregionally recurrent or metastatic) breast cancer that was not amenable to curative therapy.
  • The patient was postmenopausal. Postmenopausal status was defined either by:
  • 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.
  • There was no prior systemic anti-cancer therapy for advanced disease.
  • The patient had a histologically and/or cytologically confirmed diagnosis of estrogen-receptor positive and/or progesterone receptor positive breast cancer by the local laboratory.
  • The patient had HER2-negative breast cancer defined as a negative in situ hybridization test or an IHC status of 0, 1+ or 2+. If IHC was 2+, a negative in situ hybridization (FISH, CISH, or SISH) test was required by local laboratory testing.
  • The patient must have had either:
  • Measurable disease, i.e., at least one measurable lesion as per RECIST 1.1 criteria (Tumor lesions previously irradiated or subjected to other locoregional therapy were considered measurable if disease progression at the treated site after completion of therapy was clearly documented). OR If no measurable disease was present, then at least one predominantly lytic bone lesion must have been present (Patients with no measurable disease and only one predominantly lytic bone lesion previously irradiated were eligible if there was documented evidence of disease progression of the bone lesion after irradiation).
  • The patient had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

You may not qualify if:

  • The patient had received any CDK4/6 inhibitor.
  • The patient had received any prior systemic anti-cancer therapy (including hormonal therapy and chemotherapy) for advanced breast cancer.
  • Note:
  • Patients who had received (neo) adjuvant therapy for breast cancer were eligible. If the prior neo (adjuvant) therapy included letrozole or anastrozole, the disease-free interval had to be greater than 12 months from the completion of treatment until randomization.
  • Patients who had received ≤ 14 days of letrozole or anastrozole for advanced disease prior to randomization were eligible.
  • Any prior (neo) adjuvant anti-cancer therapy had to be stopped at least 5 half-lives or 7 days, whichever was longer, before randomization.
  • The patient was concurrently using other anti-cancer therapy.
  • The patient had a concurrent malignancy or malignancy within 3 years of randomization, with the exception of adequately treated, basal or squamous cell carcinoma, non-melanomatous skin cancer, or curatively resected cervical cancer.
  • The patient had active cardiac disease or a history of cardiac dysfunction, including any of the following:
  • History of angina pectoris, symptomatic pericarditis, or myocardial infarction within 12 months prior to study entry.
  • History of documented congestive heart failure (New York Heart Association functional classification III-IV).
  • Documented cardiomyopathy.
  • The patient had a Left Ventricular Ejection Fraction (LVEF) \< 50% as determined by Multiple Gated acquisition (MUGA) scan or echocardiogram (ECHO).
  • History of any cardiac arrhythmias, e.g., ventricular, supraventricular, nodal arrhythmias, or conduction abnormality in the previous 12 months.
  • On screening, any of the following cardiac parameters: bradycardia (heart rate \< 50 at rest), tachycardia (heart rate \> 90 at rest), PR interval \> 220 msec, QRS interval \>109 msec, or QTcF \>450 msec.
  • +6 more criteria
