What was measured

CBR was defined as the percentage of participants with a best overall response of CR or PR or stable disease (SD) lasting 24 weeks or longer as defined in RECIST 1.1 as per investigator assessment. CR: Disappearance of all lesions with lymph nodes measuring \< 10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease.

Analysis population: FAS including all randomized participants.

Groups in this outcome

Ribociclib + Fulvestrant

Ribociclib was administered orally at a daily dose of 600mg for 21 consecutive days within a 28-day cycle. This treatment was combined with fulvestrant, which was administered via intramuscular injections of 500mg every 28 days starting on Day 1 of each cycle. Additionally, an extra dose of fulvestrant was given on Day 15 of Cycle 1.

Placebo + Fulvestrant

Placebo was administered orally for 21 consecutive days within a 28-day cycle. This treatment was combined with fulvestrant, which was administered via intramuscular injections of 500mg every 28 days starting on Day 1 of each cycle. Additionally, an extra dose of fulvestrant was given on Day 15 of Cycle 1.
