What was measured
A time to event analysis was pre-specified for pain. An analysis of TTD in pain defined as time between baseline and first occurrence of increase of ≥10 points in pain. Deterioration will be defined increase in score of 10 points or greater from baseline. The Kaplan-Meier estimates of quartiles (time to deterioration) with 95% CI is mentioned below.
Analysis population: The PRO -evaluable population is defined as a subset of ITT participants, who have completed a baseline and at least one post -baseline PRO assessment prior to end of study treatment.
Groups in this outcome
Palbociclib + Fulvestrant
Participants were administered an initial dose of 125 mg per day orally continuously for 3 weeks followed by 1 week off that can be reduced to 100 mg or 75 mg in case of toxicity; repeated at each subsequent cycle and fulvestrant 500 mg intramuscularly on days 1 and 15 of cycle 1 and then every 28 days. Pre- and perimenopausal women received goserelin at least 4 weeks before study treatment start and continued receiving concurrent ovarian function suppression with goserelin administered subcutaneously every 28 days during the active treatment phase. Maximum treatment duration was 105 cycles.
Placebo + Fulvestrant
Participants were administered placebo orally continuously dosed for 3 weeks followed by 1 week off; repeated at each subsequent cycle and Fulvestrant 500 mg intramuscularly on Days 1 and 15 of cycle 1 and then every 28 days. Pre- and perimenopausal women received goserelin at least 4 weeks before study treatment start and continued receiving concurrent ovarian function suppression with goserelin administered subcutaneously every 28 days during the active treatment phase. Maximum treatment duration was 93 cycles.
