There are no treatments specifically approved after recurrence or progression on a non steroidal aromatase inhibitors (NSAI). In light of the need for new treatment options for postmenopausal women after failure of prior NSAI therapy, the purpose of this Phase III study is to compare efficacy and safety of a treatment with exemestane + everolimus to exemestane + placebo in postmenopausal women with estrogen receptor positive locally advanced or metastatic breast cancer refractory to NSAI.

- description
- Progression-free survival, the primary endpoint in this study, is defined as the time from the date of randomization to the date of first documented radiological progression or death due to any cause. Disease progression was based on the tumor assessment by the local radiologist or investigator using RECIST 1.0 criteria. If a patient did not progress or known to have died at the date of the analysis cut-off or start of another antineoplastic therapy, the PFS date was censored to the date of last adequate tumor assessment prior to cut-off date or start of antineoplastic therapy. For patients with lytic or mixed (lytic+sclerotic) bone lesions, the following is considered progression: appearance of ≥1 new lytic lesions in bone; the appearance of ≥ new lesions outside of bone and unequivocal progression of existing bone lesions.

- Overall response rate (ORR) is the percentage of patients with a best overall response of complete response (CR) or partial response (PR) according to RECIST 1.0. Per RECIST criteria 1.0, CR: Disappearance of all target lesions; PR: At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters.

- The ECOG PS (Eastern Cooperative Oncology Group Performance Scale) is a standard criteria for measuring how treatment of cancer impacts level of functioning in terms of the ability to care for oneself, daily activity, \& physical ability (walking, working, etc.). Scale score ranges:0 to 5, 5 being the worst. Scale index: 0: Fully active, able to carry on all pre-disease performance without restriction. 1: Restricted in physically strenuous activity but ambulatory \& able to carry out work of a light or sedentary nature. 2: Ambulatory \& capable of all self-care but unable to carry out any work activities. Up \& about more than 50% of waking hours. 3: Capable of only limited self-care, confined to bed or chair more than 50% of waking hours. 4 - Completely disabled. Cannot carry on any self-care. Totally confined to bed or chair. 5 - Dead. A deterioration of ECOG is an increase of 1 of the ECOG PS without improvement back to initial level at a subsequent time of measurement.

- The QLQ-C30 is composed of both multi-item scales and single-item measures. These include 5 functional scales, 3 symptom scales, a global health status - QoL scale, and 6 single items. Each of the multi-item scales includes a different set of items - no item occurs in more than 1 scale. All of the scales measures range in score from 0 to 100. A high scale score = higher response level. Thus a high score for a functional scale represents a healthy level of function, a high score for the global health status / QoL represents a high quality of life but a high score for a symptom scale / item represents a high level of symptomatology / problems. The principle for scoring these scales: 1.) Estimate the average of the items that contribute to the scale = raw score. 2.) Linear transformation to standardize the raw score, so that scores range from 0 to 100; a higher score represents a higher ("better") level of functioning, or a higher ("worse") level of symptoms.

- overall response = complete response (CR) + partial response (PR) per RECIST 1.0 Time to overall response (CR or PR) based on investigator is the time between date of randomization/start of treatment until first documented response (CR or PR). This analysis included all patients/responders. Patients who did not achieve a confirmed PR or CR were censored at last adequate tumor assessment date when they did not progress. Per RECIST criteria 1.0, CR: Disappearance of all target lesions; PR: At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters.
