Detailed Description

Collection of Correlative Samples at First Recurrence (Stage I consent) If feasible, optional correlative blood and fresh tissue will be collected during surgical excision of their 1st recurrence. Patients should then complete radiation therapy if that is indicated. Enrollment to the Treatment Phase will occur within 6 months of the last local treatment, surgery or radiation treatment, whichever occurred last.

Study Treatment (Stage II/ main consent)

Treatment includes:

  1. Ribociclib:

    Oral ribociclib at a dose of 600 mg daily for 21 days out of a 28-day cycle. Ribociclib will be used in combination with ET per physician choice.

  2. Physician's Choice Endocrine Therapy:

ET consists of one of the following:

  • Intramuscular fulvestrant
  • Oral anastrozole
  • Oral letrozole
  • Oral exemestane
  • Concomitant use with tamoxifen is not allowed.

Ribociclib administration is planned for 36 months and ET administration is planned for 60 months.

Outcome Measure
Measure Description
Time Frame
Recurrence Free Survival (RFS)
Time Frame: 3 years
Estimate subsequent recurrence-free survival (RFS) at 3 years for ribociclib when administered with ET (AIs or fulvestrant). RFS is defined as interval from registration until invasive or DCIS recurrence in the ipsilateral breast or locoregionally, invasive recurrence at a distant site, or death from breast cancer or any other cause, whichever occurs first. The censoring time is the completion of study at 6 years (3 years of patient accrual and 3 years of follow up time). The RFS at 3 years will be also treated as the primary endpoint in the power and sample size calculation.
3 years

Secondary Outcome Measures

Measure Description
Time Frame
Distant Metastasis-Free Survival
Time Frame: 3 years
