Patients on stable low dose of corticosteroids for at least two weeks before randomisation are allowed 7.Current refractory nausea and vomiting, chronic gastrointestinal disease or inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of the study medication 8.Clinically significant pulmonary dysfunction 9.Significant cardiovascular disease; patients who have experienced any of the following procedures or conditions currently or in the preceding 12 months: a.Myocardial infarction, acute coronary syndromes (including unstable angina), or coronary angioplasty/stenting/bypass grafting. b.Symptomatic congestive heart failure (CHF) New York Heart Association (NYHA) Classes II-IV or LVEF 100 mmHg) e.Clinically significant valvular disease, cardiomegaly, ventricular hypertrophy, or cardiomyopathy 10.QTc prolongation defined as a QTc interval >470 msecs or other significant ECG abnormalities including 2nd degree (type II) or 3rd degree AV block or bradycardia (ventricular rate <50 beats/min) 11.Concomitant medications known to prolong QT interval, or with factors that increase the risk of QTc prolongation or risk of arrhythmic events (such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age) 12.Clinically significant abnormalities of glucose metabolism as defined by any of the following a.Diagnosis of diabetes mellitus type I (irrespective of management) or uncontrolled diabetes mellitus type II b.Glycosylated haemoglobin (HbA1C) =8.0% at screening (64 mmol/mol) (conver

| Main Objective: The main aims of this study are to: • Determine whether dual inhibition of mTORC 1 and mTORC2 with AZD2014 will increase the anti-tumour activity of endocrine treatment with fulvestrant in ER-positive advanced or metastatic breast cancer. • Determine whether inhibition of both mTORC 1 and mTORC2 using AZD2014 will have superior anti-tumour activity compared to inhibition of mTORC1 alone with everolimus, when combined with fulvestrant. • Explore whether additional efficacy is likely to be present in a subgroup with PI3K-pathway activation for whom it is hypothesised that there will be greater sensitivity to mTOR inhibitors • Characterize the patient population who might benefit from fulvestrant plus AZD2014 to identify potential predictors of sensitivity The primary objectives of this study are to: • Estimate the clinical benefit of fulvestrant + AZD2014 relative to fulvestrant + everolimus or fulvestrant alone, as measured by investigator-assessed progression-free survival (PF;Secondary Objective: The secondary objectives of this study are to: • Estimate the clinical benefit of fulvestrant + AZD2014 relative to fulvestrant + everolimus or fulvestrant alone, as measured by PFS as assessed by an independent review facility [IRF] • Assess the clinical activity, as measured by response rate (RECIST 1.1), clinical benefit rate, duration of clinical benefit and duration of response, of fulvestrant + AZD2014 relative to fulvestrant + everolimus or fulvestrant alone • Establish the safety and tolerability of fulvestrant + AZD2014 relative to fulvestrant + everolimus or fulvestrant alone • Estimate the overall survival benefit of fulvestrant + AZD2014 relative to fulvestrant + everolimus or fulvestrant alone • Investigate the effects of fulvestrant +/- AZD2014 or everolimus on bone-turnover biomarkers • Compare the differences in patient reported outcomes as measured by the Functional Assessment of Cancer Therapy-General (FACT-G) scale together with th | — |

| Secondary end point(s): The secondary outcome measures for this study are as follows: Efficacy 1. Progression-free survival, defined as the time from the date of randomisation to the date of first documented tumour progression as assessed by an independent review facility [IRF] (using RECIST 1.1) or death from any cause, whichever occurs first. 2. Objective response, defined as a complete or partial response, based on investigator and IRF assessment using RECIST 1.1. 3. Average change (%) in tumour size at 16 weeks compared to baseline, based on investigator and IRF assessment using RECIST 1.1; tumour size is defined as the sum of the longest diameters of the target (i.e. measurable tumour) lesions. 4. Clinical Benefit, defined as number of patients with complete or partial response or stable disease maintained =24 weeks, based on investigator and IRF assessment using RECIST 1.1). 5. Overall survival, defined as the time from date of randomisation to the date of death due to any cause. 6. Duration of response, defined as the time from first documentation of complete or partial response to disease progression based on investigator and IRF assessment using RECIST 1.1. 7. Duration of clinical benefit, defined as the time from randomisation to disease progression based on investigator and IRF assessment using RECIST 1.1 in patients with CB. 8. Percentage change in serum of serum beta C-terminal cross-linking telopeptide of Type I collagen (ßCTx) and N-terminal propeptide of Type I procollagen (PINP) from screening/baseline to each time that samples are collected. 9.
