What was measured

DOR was the time from the date of first evidence of complete response or partial response to the date of objective progression or the date of death due to any cause, whichever is earlier. CR and PR were defined using the RECIST v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. If a responder was not known to have died or have objective progression as of the data inclusion cutoff date, duration of response was censored at the last adequate tumor assessment date. PD was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions.

Analysis population: All randomized participants with response.

Groups in this outcome

Abemaciclib + Fulvestrant

Abemaciclib 150 mg administered orally every 12 hours on Days 1 to 28 of a 28-day cycle in combination with fulvestrant 500mg administered IM on Days 1 and 15 of Cycle 1, then on Day 1 of Cycle 2 and beyond. Participants received treatment until discontinuation were met.

Placebo + Fulvestrant

Placebo administered orally every 12 hours on Days 1 to 28 of a 28-day cycle in combination with fulvestrant 500mg administered IM on Days 1 and 15 of Cycle 1, then on Day 1 of Cycle 2 and beyond. Participants received treatment until discontinuation were met.
