Experimental: 150 mg Abemaciclib + 8 mg/kg Trastuzumab + 500 mg Fulvestrant - 150 milligram (mg) abemaciclib given orally every 12 hours (Q12H) of a 21-day cycle; plus 8 milligram per kilogram (mg/kg) trastuzumab intravenous (IV) infusion on Day 1 of the cycle then a 6 mg/kg maintenance dose IV infusion on Day 1 of each subsequent cycle; plus 500 mg fulvestrant intramuscularly (IM) on day 1, 15 and 29 and then once every 4 weeks thereafter.

Experimental: 150 mg Abemaciclib + 8 mg/kg Trastuzumab - 150 mg abemaciclib given orally Q12H of a 21-day cycle; plus 8 mg/kg trastuzumab IV infusion on Day 1 of the cycle then a 6 mg/kg maintenance dose IV infusion on Day 1 of each subsequent cycle.

Active Comparator: 8 mg/kg Trastuzumab + Standard of Care Chemotherapy - 8 mg/kg trastuzumab IV infusion on Day 1 of a 21-day cycle then a 6 mg/kg maintenance dose IV infusion on Day 1 of each subsequent cycle plus standard of care single agent chemotherapy of physician's choice administered according to product label
