Inclusion criteria

Inclusion criteria: 1.

Locally advanced or mBC not deemed amenable to curative surgery or curative radiation therapy 3. Archival tumour sample available at the time of informed consent and provided to the central laboratory around the time of randomisation. Patients must provide a formalin-fixed paraffin embedded (FFPE) tissue biopsy sample preferably taken at the time of presentation with recurrent or metastatic disease (provision of a biopsy sample taken from the bone is not acceptable). If archival tissue is not available, provision of detailed information from the original histology report may be agreed with the sponsor on a case by case basis. 4. Patients must satisfy the following criteria for prior therapy: Disease progression during treatment or within 12 months of completion of endocrine adjuvant therapy OR Disease progression while on or within 1 month after the end of prior endocrine therapy for advanced/metastatic breast cancer (Note: the endocrine therapy does not have to be the treatment immediately prior to trial entry). 5. Inclusion criteria 5 is not applicable for patients enrolled after protocol version 4 is approved. 6. Inclusion criteria 6 is not applicable for patients enrolled after protocol version 4 is approved. 7. Female patients =18 years old or over the legal age of consent in countries where that is greater than 18 years at the time of informed consent. Patients must be either: ? Premenopausal on ovarian suppression with a gonadotropin-releasing hormone (GnRH) agonist with FSH and estradiol in postmenopausal range (initiated at least 28 days prior screening) OR ? Post-menopausal, defined as one of the following: • Age = 60 years • Age < 60 years and amenorrheic for 12 or more months in the absence of chemotherapy, tamoxifen, toremifene, or ovarian suppression, and FSH and estradiol in the postmenopausal range. • If taking tamoxifen or toremifene, and age < 60 years, then FSH and estradiol level in post-menopausal range. • Surgical menopause with bilateral oophorectomy 8. Patients must have an indication for combination treatment with everolimus and exemestane. 9. Patients must have ? At least one measurable non-visceral lesion according to RECIST version 1.1 in either lymph nodes, soft tissue, skin AND/OR ? At least one measurable non-visceral lesion according to RECIST version 1.1 as lytic or mixed (lytic + blastic) in bone AND/OR ? At least one non-measurable (lytic, mixed lytic + blastic, or blastic) bone lesion according to RECIST version 1.1 10. Eastern Cooperative Oncology Group (ECOG) performance score 0 or 1 11. Fasting glucose <8.9 mmol/L (<160 mg/dL) and HbA1c <8.0% 12. Adequate organ function, defined as all of the following: a) Absolute neutrophil count (ANC) =1500/mm3 b) Platelet count =100,000/mm3 c) International Normalised Ratio (INR) =2.0 d) Serum creatinine =1.5 times upper limit of institutional normal (ULN) or creatinine clearance =50 mL/min (measured or calculated by Cockcroft and Gault formula). e)Total Bilirubin =1.5 times ULN (patients with Gilbert syndrome total bilirubin must be <4 times ULN) f) Aspartate amino transferase (AST) and alanine amino transferase (ALT) =2.5 times

Exclusion criteria

Exclusion criteria: 1. Previous treatment with agents targeting the IGF pathway, AKT, or mTOR pathways (sirolimus, temsirolimus, etc.) 2. Prior treatment with exemestane (except adjuvant exemestane stopped >12 months prior to start of study treatment as long as the patient did not recur during or within 12 months after the end of adjuvant exemestane) 3. Evidence of visceral metastasis/es (i.e. liver, lung, peritoneal, pleural metastases, malignant pleural effusions, malignant peritoneal effusions) at screening. NOTE: Patients with a past history of visceral metastases are eligible if visceral metastases have completely resolved at least 3 months prior to screening. 4. History or evidence of metastatic disease to the brain 5. Leptomeningeal carcinomatosis 6. Known hypersensitivity to any of the study drugs or their excipients 7. Any contraindication to treatment with everolimus or exemestane 8. More than 1 prior line of chemotherapy for HR+ HER2- metastatic breast cancer 9. Radiotherapy within 4 weeks prior to the start of study treatment, except in case of localised radiotherapy for analgesic purpose or for lytic lesions at risk of fracture which can then be completed within two weeks prior to study treatment 10. Major surgery (major according to the investigator’s assessment) performed within 4 weeks prior to randomisation or planned after screening 11. Use of concomitant systemic sex hormone therapy (e.g. Megace) within 2 weeks Prior to start of trial treatment. NOTE: Ovarian suppression with GnRH agonists is permitted in premenopausal patients. 12. History or presence of cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure NYHA classification of =3, unstable angina or poorly controlled arrhythmia which are considered as clinically relevant by the investigator. Myocardial infarction within 6 months prior to randomisation. 13. Any history of or concomitant condition that, in the opinion of the Investigator, would compromise the patient’s ability to comply with the study or interfere with the evaluation of the efficacy and safety of the study medications. 14. Previous or concomitant malignancies at other sites, except effectively treated a) Non-melanoma skin cancers b) Carcinoma in situ of the cervix c) Ductal carcinoma in situ d) Other malignancy that has been in remission for more than 3 years and is considered to be cured. 15. Known pre-existing interstitial lung disease (ILD). 16. Known active hepatitis B infection (defined as presence of Hep B sAg and/or Hep B DNA), active hepatitis C infection (defined as presence of Hep C RNA) and/or known Human immunodeficiency virus (HIV) carrier 17. Active infectious disease which puts the patient at increased risk in the opinion of the investigator 18. Any history or presence of uncontrolled gastrointestinal disorders that could affect the intake and/or absorption of the study drug (e.g. nausea, uncontrolled vomiting, Crohn’s disease, ulcerative colitis, chronic diarrhoea, malabsorption) in the opinion of the investigator 19. Previous randomisation in this trial 20. Concurrent participation in another clinical trial with an investigational device or drug. 21.

Topical applications (e.g. for rash), inhaled sprays (e.g. for obstructive airways diseases), eye drops, mouth washes or local injections (e.g. intra-articular) are allowed ?

Design outcomes

Primary

MeasureTime frame
Main Objective: To show efficacy of xentuzumab in combination with everolimus and exemestane over everolimus and exemestane in this patient population.;Secondary Objective: To determine further efficacy and safety of xentuzumab in combination with exemestane and everolimus in HR+/HER2- advanced or metastatic breast cancer patients with non-visceral disease.;Primary end point(s): The primary endpoint to determine efficacy of xentuzumab is progression-free survival (PFS) which is defined as time from randomisation until disease progression according to Response Evaluation Criteria In Solid Tumors (RECIST, version 1.1) or death from any cause, whichever occurs earlier.;Timepoint(s) of evaluation of this end point: The timepoint of primary evaluation of PFS will take place when 40 PFS events have occurred

Secondary

MeasureTime frame
Secondary end point(s): 1) Overall survival (OS) 2) Disease control (DC) 3) Duration of DC 4) Objective response (OR) 5) Time to pain progression or intensification of pain palliation;Timepoint(s) of evaluation of this end point: 1) The timepoint of primary evaluation of OS will take place when all patients have completed treatment and attended FU1 2) Same timepoint as PFS analysis 3) Same timepoint as PFS analysis 4) Same timepoint as PFS analysis 5) Same timepoint as PFS analysis
