Treatment duration is defined as the time from randomization until the date of permanent study treatment discontinuation (for any reason) at any time during the Core phase.

    The percentage event-free probability estimate is the estimated probability that a patient will remain on-treatment up to a specified time point (Week 6, 12, 18)


  6. Core Phase: Change From Baseline in the QOLCE Overall Quality-of-life Score for Patients <11 Years [ Time Frame: Baseline, Week 18 ]
    Comparison of quality of life in the everolimus (from 3 age specific questionnaires) low-trough treatment arm (3-7 ng/mL), high-trough treatment arm (9-15 ng/mL) and placebo arm at the end of the core phase. The Quality of Life Childhood Epilepsy (QOLCE) questionnaire, used for patients < 11 years at baseline, was completed by the patient's parent or caregiver. It consists of 16 subscales (13 multi-item scales and 3 single item scales) and one overall quality-of-life score. Scores range from 0-100, with higher scores corresponding to improved QoL. The Overall Quality of Life Score is computed by adding each subscale score for each individual and then dividing by 16.

    Comparison of quality of life (from 3 age specific questionnaires) in the everolimus low-trough treatment arm (3-7 ng/mL), hightrough treatment arm (9-15 ng/mL) and placebo arm at the end of the core phase. The Quality of Life in Epilepsy Inventory-31-Problems (QOLIE-31-P) is a survey of health-related quality of life for adults with epilepsy. The QOLIE-31-P is completed by the patient. It contains 39 items, of which a total of 30 are used to make up 7 different subscales. Scores range from 0-100, with higher scores indicating a greater level of functioning and QoL. The overall quality of life score is obtained by summing a linear combination of the 7 subscale scores, where each subscale is multiplied by a relative weight that is obtained from the patient's answer to 7 items of this questionnaire.

  9. Core Phase: Change From Baseline in the Overall Vineland-II Adaptive Behavior Composite (ABC) Score [ Time Frame: Baseline, 18 weeks ]
    Comparison of adaptive functioning using the VABS-II composite score in the everolimus low-trough treatment arm (3-7 ng/mL), high-trough treatment arm (9-15 ng/mL) and placebo arm. The Vineland II assesses an individual's development of personal independence & social responsibility. The questionnaire contains 433 items which assess 15 subdomains organized into the five domains of Communication, Daily Living Skills, Socialization, Motor Skills and Maladaptive Behavior. The overall Adaptive Behavior Composite (ABC) score is obtained by summing the standard scores of the first four domain scores for patients aged less than 7 years, or the first 3 domain scores for patients aged 7 or older (the Maladaptive Behavior domain is optional). The ABC standard score ranges from 20 to 160 with a mean of 100 and a standard deviation of 15. Higher scores correspond to improved adaptive level. Note that 2 questionnaires with ABC scores<20 (data issues) were included in this analysis.

  11. Core Phase: Change From Baseline in Wechsler Nonverbal Composite Score [ Time Frame: Baseline, Week 18 ]
    The brief version of the WNV consists of a 2-subtest battery: only Matrices and Recognition subtests for patients under 8, and Matrices and Spatial Span subtests for patients aged 8 to 21. Based on the raw scores obtained from the subtests, standardized z-scores were calculated for each subtest using the following formula: Zscore = (X - b)/Sb where X is the raw score of the subtest, b and Sb represent the mean and standard deviation respectively of the subtest score recorded at baseline for the study population. The composite WNV score was computed by summing up the Z-scores of the 3 subtests of the WNV (i.e. matrices, recognition, and coding for patients aged <8 years and matrices, spatial span, and coding for patients aged 8 to 21 years). The composite WNV score has no range.

  12. Long Term Evaluation: Effect of Everolimus Over Time in the Overall Wechsler Nonverbal Composite Score [ Time Frame: Baseline, Weeks 18, 42, 66 and 90 ]
    The brief version of the WNV consists of a 2-subtest battery: only Matrices and Recognition subtests for patients under 8, and Matrices and Spatial Span subtests for patients aged 8 to 21. Based on the raw scores obtained from the subtests, standardized z-scores were calculated for each subtest using the following formula: Zscore = (X - b)/Sb where X is the raw score of the subtest, b and Sb represent the mean and standard deviation respectively of the subtest score recorded at baseline for the study population. The composite WNV score was computed by summing up the Z-scores of the 3 subtests of the WNV (i.e. matrices, recognition, and coding for patients aged <8 years and matrices, spatial span, and coding for patients aged 8 to 21 years). The composite WNV score has no range

Response rate is the percentage of patients with ≥ 50% reduction from baseline in average weekly partial-onset seizure frequency during the maintenance period of the Core phase.

  14. Core Phase: Median Percentage Change From Baseline in Seizure Frequency by Time Normalized Minimum Concentration [ Time Frame: Baseline (8-week period before randomization), Week 7 to 18 (12-week maintenance period of the core phase) ]
    Percentage change from baseline in average weekly seizure frequency during the maintenance period of the Core phase is calculated as follow: (SFcfb) = 100 × (SFB - SFM) ÷ SFB where SFB is the average weekly seizure frequency in the Baseline phase and SFM is the average weekly seizure frequency in the maintenance period of the Core phase. A positive percentage change from baseline (SFcfb) means a reduction in seizure frequency whereas a negative percentage change from baseline (SFcfb) means an increase in seizure frequency.

  15. Long Term Evaluation: Relationship Between Seizure Frequency and Time-normalized Everolimus Concentration at Trough (Cmin,TN) - Repeated Measures Analysis [ Time Frame: During everolimus treatment from start of everolimus up to the end of the extension phase, an average of 1.7 year ]
    A repeated measures analysis considering fixed 2-week intervals and including the level of exposure (time-normalized Cmin values), the time on-treatment and the seizure frequency at baseline quantified the estimated percentage change over 2 weeks in seizure frequency associated with a double exposure to everolimus, 15 days more on treatment and half the seizure frequency at baseline. A positive percentage change means a reduction in seizure frequency whereas a negative percentage change means an increase in seizure frequency.

  16. Core Phase: Impact of Everolimus on Anti-epileptic Drugs (AEDs) Concentrations [ Time Frame: Baseline, Weeks 1 & 3 ]
    Impact of everolimus on AED concentrations at trough. Pre-dose plasma samples to measure AED concentrations were measured at at Visits 1 (Screening), 2 (Baseline), 3, and 5. Effects of everolimus on the exposure of antiepileptic drugs was assessed by comparing the anti-epileptic drug concentrations at Visits 1 and 2 (AEDs alone) and at Visits 3 and 5 (AEDs plus everolimus).

  17. Long Term Evaluation: Percentage Change From Start of Everolimus in Seizure Frequency by Time Window [ Time Frame: Baseline (8-week period before start of everolimus), Week 7 to 18, Week 19 to 30, and 12 weeks thereafter up to Week 102 ]

    Percentage change from start of everolimus in average weekly seizure frequency (SFcfe) = 100 × (SFe - SFtw) ÷ SFe where:

    SFe is the average weekly seizure frequency in the 8-week period before start of everolimus SFtw is the average weekly seizure frequency in a 12-week time window A positive percentage change from start of everolimus (SFcfe) means a reduction in seizure frequency whereas a negative percentage change from start of everolimus (SFcfe) means an increase in seizure frequency.


  18. Seizure Free Rates by Time Window [ Time Frame: Weeks 18, 30, 42, 54, 66, 78, 90 & 102 ]
    Percentage of seizure-free participants for each 12-week time window.

  19. Core Phase: Incidence of Suicide Attempt, Suicidal Ideation or Behavior During Core Phase Per Columbia Suicide Severity Rating Scale (C-SSRS) Outcomes [ Time Frame: Baseline, Week 18 ]
    Comparison of suicidality using the C-SSRS in the everolimus low-trough treatment arm (3-7 ng/mL), high-trough treatment arm (9-15 ng/mL) and placebo arm. The Columbia-Suicide Severity Rating Scale (C-SSRS) is a questionnaire used for suicide assessment developed by multiple institutions, including Columbia University, with NIMH support. The scale is evidence-supported and is part of a national and international public health initiative involving the assessment of suicidality. There are different scoring systems depending on the population. The important elements to note are that the higher the scores on the individual items and the more "yes" items, the higher the suicide risk.

  20. Long Term Evaluation: Incidence of Suicide Attempt, Suicidal Ideation or Behavior During Core Phase Per Columbia Suicide Severity Rating Scale (C-SSRS) Outcomes [ Time Frame: During everolimus treatment from start of everolimus up to permanent discontinuation of everolimus, an average of 2.3 years ]
    The C-SSRS was completed at each visit. The table below presents the number of patients who reported at least one completed suicide, one suicide attempt, one preparatory action toward imminent suicidal behavior, one suicidal ideation and one self-injurious behavior without suicidal intent at any time point after starting everolimus.
