Safety and Efficacy of Everolimus in Metastatic Renal Cell Carcinoma After Failure of First Line Therapy With Sunitinib or Pazopanib

Percentage of progression-free patients by month 6 after starting everolimus treatment. For the purpose of the binomial design of the study, a patient being 'progression-free' will be defined as a patient without disease progression by month 6 whereas a subject with progressive disease by month 6 will not be counted as 'progression-free'. The primary variable was derived from radiologic tumor assessments according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1.) Disease progression was either 1) a 20% increase in the sum of the longest diameter of all target lesions, taking as reference the smallest sum of the longest diameters of all target lesions recorded at or after baseline (minimum absolute increase 5 mm in sum) or 2) the appearance of a new lesion or 3) the unequivocal progression of non-target lesions overall.

Overall response rate (ORR) is the Percentage of patients with a best overall response of complete response (CR) or partial response (PR) by month 6. ORR was assessed according to RECIST 1.1 criteria. Partial response (PR) required at least a 30% decrease in the sum of the longest diameters of all target lesions, taking as reference the baseline sum of the longest diameters. Complete response (CR) required a disappearance of all target and non-target lesions.

Progression-free survival (PFS) is the time from date of start of treatment to the date of event defined as the first documented progression or death due to any cause. If a patient did not have an event, progression-free survival was censored at the date of last adequate tumor assessment

Overall survival (OS) was defined as the time from date of start of treatment to date of death due to any cause. If a patient was not known to have died, survival will be censored at the date of last contact.

The duration of overall response (DOR) was defined as the time from the first occurrence of a confirmed Complete Response (CR) or Partial Response (PR) (as per investigator assessment according to RECIST 1.1) until the date of the first documented disease progression or death due to underlying cancer. If a patient did not have an event or received any further anticancer therapy, duration of overall response was censored at the date of last adequate tumor assessment. Duration of response was displayed only for patients whose best overall response was CR or PR. As none of the patients showed any response (CR or PR), DOR could not be calculated
