Primary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS) - Phase II PartFrom randomisation until radiological tumour progression according to RECIST 1.1, or death from any cause or data cut-off (25Nov2016), up to 30 months.

Progression-free survival (PFS) in the phase II part is presented. Progression-free survival (PFS) was defined as the time from randomisation until radiological tumour progression according to RECIST 1.1, or death from any cause, whichever occurred earlier. Clinical disease progression was not considered for determination of a PFS event, unless the outcome of the progression was death. The cut-off date was 25th November 2016. At cut-off date, xentuzumab was discontinued in all patients in the experimental arm per sponsor decision, recruitment was also terminated. Patients who discontinued xentuzumab treatment continued with everolimus 10 mg + exemestane 25 mg treatment.

Number of Patients With Dose Limiting Toxicity (DLT) - Phase Ib PartFrom first administration of study treatment until end of first treatment cycle, up to 28 days.

Number of patients with dose limiting toxicity (DLT) in phase Ib part is presented.

Maximum Tolerated Dose (MTD) - Phase Ib Partup to 28 days.

The Maximum Tolerated Dose (MTD) in this study was defined as the highest dose level examined of trial medication, at which no more than 1 out of 6 patients experienced a DLT during the MTD evaluation period.

The MTD evaluation period was defined as the time from the first administration of xentuzumab up to start of cycle 2.

A "3+3" Phase Ib dose finding phase was performed to determine the MTD.

Secondary Outcome Measures
NameTimeMethod
Number of Patients With Objective Response (OR) - Phase II PartFrom randomisation until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy or data cut-off (25Nov2016), up to 30 months.

Objective response (OR) - phase II part is presented. Objective response (OR), defined as best overall response of complete response (CR) or partial response (PR), where best overall response was determined according to RECIST 1.1 from date of randomisation until the earliest of disease progression, death or last evaluable tumour assessment before start of subsequent anti-cancer therapy.

Time to Progression (TTP) - Phase II PartFrom randomisation until the date of the first objective tumour progression according to RECIST 1.1. or data cut-off (25Nov2016), up to 30 months.

Time to progression (TTP) is presented. Time to progression (TTP), defined as the time from the date of randomization until the date of the first objective tumour progression according to RECIST 1.1.

Number of Patients With Disease Control (DC) - Phase II PartFrom randomisation until data cut-off (25Nov2016), up to 30 months.

Disease control is defined as best overall response of complete response (CR) or partial response (PR), or stable disease (SD) \>= 24 weeks, or Non-CR/Non-PD for \>= 24 weeks. PD=Progressive disease.

Time to Objective Response - Phase II PartFrom randomisation until first documented complete response (CR) or partial response (PR) or data cut-off (25Nov2016), up to 30 months.

Time to objective response is presented. Time to objective response is defined as the time from randomisation until first documented complete response (CR) or partial response (PR).

Duration of Objective Response - Phase II PartFrom randomisation until the earliest of disease progression or death or data cut-off (25Nov2016), up to 30 months.

Duration of objective response is presented. Duration of objective response is defined as the time from first documented complete response (CR) or partial response (PR) until the earliest of disease progression or death among patients with objective response (OR).

Duration of Disease Control - Phase II PartFrom randomisation until the earliest of disease progression or death or data cut-off (25Nov2016), up to 30 months.

Duration of disease control is presented. Duration of disease control is defined as the time from randomisation until the earliest of disease progression or death, among patients with disease control.
