What was measured

ORR is the best overall tumor response of CR or PR as classified by the investigator according to the Response Evaluation Criteria In Solid Tumors (RECIST v1.1). CR is a disappearance of all target and non-target lesions and normalization of tumor marker level. PR is an at least 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameter) without progression of non-target lesions or appearance of new lesions.

Analysis population: All randomized participants.

Groups in this outcome

Arm A: Abemaciclib Plus Fulvestrant

Abemaciclib 150 mg administered orally BID on Days 1 to 28 of a 28-day cycle in combination with fulvestrant 500 mg administered IM on Days 1 and 15 of Cycle 1, then on Day 1 of Cycle 2 and beyond. Participants received treatment until discontinuation criteria were met.

Arm B: Placebo Plus Fulvestrant

Placebo administered orally BID on Days 1 to 28 of a 28-day cycle in combination with fulvestrant 500 mg administered IM on Days 1 and 15 of Cycle 1, then on Day 1 of Cycle 2 and beyond. Participants received treatment until discontinuation criteria were met.
