What was measured

Number of participants with shifts from Grade ≤2 at baseline values to post-baseline values (shift to Grade 3 or 4) were reported as per NCI-CTCAE, V4.0 graded from Grade 1 to 5. Grade 1: Mild; asymptomatic/ mild symptoms; clinical/diagnostic observations only; intervention not indicated. Grade 2: Moderate; minimal, local/noninvasive intervention indicated. Grade 3: Severe/medically significant but not immediately life-threatening; hospitalization/prolongation of hospitalization indicated. Grade 4: Life-threatening consequences; urgent intervention indicated. Shifts in lab parameter from Grade ≤2 at baseline to Grade 3 or 4 postbaseline (for parameters ALT increased, ALP increased, AST increased, Blood bilirubin increased, Creatinine increased, Hypercalcemia, Hyperkalemia, Hypermagnesemia, Hypernatremia, Hypoalbuminemia, Hypocalcemia, Hypokalemia, Hypomagnesemia, and Hyponatremia) were reported.

Analysis population: The as-treated (AT) population or safety analysis set included all participants who received at least 1 dose of study intervention, with treatment assignments designated according to actual study intervention received.

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.
