Tumor response and disease progression were assessed using response evaluation criteria in solid tumors (RECIST), version 1.0. All target and non-target lesions identified at baseline were assessed using the same method, CT scan with contrast or MRI with contrast, throughout the trial. All scans were reviewed by independent, central radiology. Disease progression was defined as: 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 or 2) the appearance of a new lesions or 3) the unequivocal progression of non-target lesions overall.

Full Analysis Set: This set consists of all randomized participants.

Overall survival (OS) was defined as the time of randomization to the date of death due to any cause.

Overall response is defined as the number of participants having achieved confirmed Complete Response (CR) + Partial Response (PR). Confirmed CR = at least two determinations of CR at least 4 weeks apart before progression. Confirmed PR = at least two determinations of PR or better at least 4 weeks apart before progression. CR required a disappearance of all target and non-target lesions. PR required at least a 30% decrease in the sum of the longest diameters of all target lesions, taking as a reference the baseline sum of the longest diameters. Disease progression was defined as: 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 or 2) the appearance of a new lesions or 3) the unequivocal progression of non-target lesions overall.

The duration of response, applied only to participants with best overall response at CR or PR, is defined as the number of days between the date of first documented response (CR or PR) and the date of the event: radiological progression as per central review or death due to underlying cancer, whichever occurs first. If no event, participant is censored at the last adequate assessment.

A subset of participants from the full analysis set were analyzed. The full analysis set consists of all randomized participants. the subset includes participants who were complete responders or partial responders.

Participants were monitored for adverse events, serious adverse events and deaths throughout the study. Participants were assessed continuously at each 28-day cycle.

Safety Set: The safety set included all participants who received at least one dose of study drug (everolimus, bevacizumab or IFN) and had a valid post-baseline assessment. No AE or occurrence of death, noted at assessment, constitutes a valid post-baseline safety assessment.

The analysis of this outcome measure was based on the FKSI-DRS scale which is a validated disease-related symptom index containing 9 items that measure symptoms predominantly related to kidney cancer. Each item is scored on a 5-point scale (0 = not at all; 4 = very much). If at least 5 of the 9 questions have been answered, the FKSI-DRS total score is calculated by subtracting nine times the mean of the scores of the answered items from 36. Participants with less than 5 out of the 9 questions answered will have a missing FKSI-DRS total score. The FKSI-DRS total score ranges from 0 (most severe symptoms) to 36 (no symptoms). Definitive deterioration is defined as a decrease by at least 2 units compared to baseline, with no later increase above this threshold observed during the study. A single measure reporting a decrease of at least 2 units was considered definitive only if it is the last one available for the participant.

The EORTC QLQ-C30 contains 30 items. These include five functional scales (physical, role, emotional, social and cognitive functioning), three symptom scales (fatigue, pain, nausea, and vomiting), a global health status/QoL scale, and six single items (dyspnea, diarrhea, constipation, anorexia, insomnia and financial impact). The PF subscale consists of 5 questions each scored from 1 (not at all) to 4 (very much). The score for the PF subscale and global health status range from 0 to 100, with a higher score representing a high level of functioning/high quality of life. Definitive deterioration by at least 10% is defined as a decrease in score by at least 10% compared to baseline, with no later increase above this threshold observed during the course of the study. A single measure reporting a decrease of at least 10% is considered definitive only if it is the last one available for the participant.
