Brief Summary:

This randomized, open-label, multicenter, 2-arm study will investigate the efficacy, safety, tolerability and pharmacokinetics of bevacizumab when added to postoperative radiotherapy with concomitant and adjuvant TMZ as compared to postoperative radiotherapy with concomitant and adjuvant TMZ alone in paediatric participants with newly diagnosed histologically confirmed World Health Organization (WHO) Grade III or IV localized supratentorial or infratentorial cerebellar or peduncular high grade glioma (HGG). Participants will be randomly assigned to one of two treatment arms.

Upon approval by the Health Authorities/Ethics Committees in the participating countries, an additional young participant cohort (YPC) (children >/= 6 months and < 3 years of age with progressive or relapsed metastatic or localized, supra- or infratentorial, non-brain stem WHO Grade III or IV HGG) was included in the study. Children in the YPC will receive bevacizumab and TMZ without radiation therapy. The anticipated time on study treatment is over 1 year.

Primary Outcome Measures :
  1. Event-Free Survival (EFS) as Assessed by the Central Radiology Review Committee (CRRC) [ Time Frame: From the time of randomization to the date of any defined event (up to approximately 52 months) ]
    EFS was defined as the time from diagnosis to the earliest occurrence of any of the following: tumor progression, tumor recurrence, second primary non-high-grade glioma (HGG) malignancy or death attributable to any cause. Tumor assessments were conducted using magnetic resonance imaging (MRI) and reviewed by the site-independent CRRC using Response Assessment in Neuro-Oncology (RANO) criteria. Tumor progression was defined as clear clinical progression or a greater than or equal to (>/=) 25% increase in the sum of the products of perpendicular diameters of the contrast enhancing lesions compared with the smallest tumor measurement obtained either at baseline (if no decrease was observed) or best response and with the participant on stable or increasing doses of corticosteroids. Tumor recurrence was defined as recurrence after tumor was completely resected (no disease present at baseline). EFS was estimated using the Kaplan-Meier method.


Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: From the time of randomization to the date of death (up to approximately 52 months) ]
    Overall Survival was defined as the time of diagnosis to the date of death due to any cause. Overall Survival was estimated using the Kaplan-Meier method.

  2. Percentage of Participants With 1-Year Survival [ Time Frame: 1 year ]
    1-year survival was estimated using the Kaplan-Meier method.

  3. Percentage of Participants With EFS as Determined by the CRRC at 6 Months [ Time Frame: 6 months ]
    EFS was defined as the time from diagnosis to the earliest occurrence of any of the following: tumor progression, tumor recurrence, second primary non- HGG malignancy or death attributable to any cause. Tumor assessments were conducted using MRI and reviewed by the site-independent CRRC using RANO criteria. Tumor progression was defined as clear clinical progression or >/= 25% increase in the sum of the products of perpendicular diameters of the contrast enhancing lesions compared with the smallest tumor measurement obtained either at baseline (if no decrease was observed) or best response and with the participant on stable or increasing doses of corticosteroids. Tumor recurrence was defined as recurrence after tumor was completely resected (no disease present at baseline). EFS was estimated using the Kaplan-Meier method.

  4. Percentage of Participants With EFS as Determined by the CRRC at 1 Year [ Time Frame: 1 year ]
    EFS was defined as the time from diagnosis to the earliest occurrence of any of the following: tumor progression, tumor recurrence, second primary non- HGG malignancy or death attributable to any cause. Tumor assessments were conducted using MRI and reviewed by the site-independent CRRC using RANO criteria. Tumor progression was defined as clear clinical progression or >/= 25% increase in the sum of the products of perpendicular diameters of the contrast enhancing lesions compared with the smallest tumor measurement obtained either at baseline (if no decrease was observed) or best response and with the participant on stable or increasing doses of corticosteroids. Tumor recurrence was defined as recurrence after tumor was completely resected (no disease present at baseline). EFS was estimated using the Kaplan-Meier method.

  5. EFS as Assessed by the Investigator [ Time Frame: From the time of randomization to the date of any defined event (up to approximately 52 months) ]
    EFS was defined as the time from diagnosis to the earliest occurrence of any of the following: tumor progression, tumor recurrence, second primary non-HGG malignancy or death attributable to any cause. Tumor assessments were conducted using MRI and reviewed by the investigator using RANO criteria. Tumor progression was defined as clear clinical progression or >/= 25% increase in the sum of the products of perpendicular diameters of the contrast enhancing lesions compared with the smallest tumor measurement obtained either at baseline (if no decrease was observed) or best response and with the participant on stable or increasing doses of corticosteroids. Tumor recurrence was defined as recurrence after tumor was completely resected (no disease present at baseline). EFS was estimated using the Kaplan-Meier method.

  6. Objective Response Rate (ORR) [ Time Frame: From the time of randomization of the first participant to the date of clinical cutoff (approximately 52 months) ]
    ORR was defined as the percentage of participants with a complete response (CR) or partial response (PR) determined on two consecutive occasions >/= 4 weeks apart. Tumor assessments were conducted using MRI and reviewed by the site-independent CRRC using RANO criteria. The following were needed to qualify as CR: complete disappearance of all measurable enhancing lesions sustained for at least 4 weeks by MRI, no steroids above physiological levels, clinical status stable or improved compared to baseline. The following were needed to qualify as PR: ≥ 50% decrease from baseline in the sum of products of perpendicular diameters of all measurable enhancing lesions sustained for at least 4 weeks by MRI, steroid dose not increased compared to baseline, clinical status stable or improved compared to baseline.

  7. Concordance Between Structural Versus Multimodal Imaging for CRRC-Assessed Event-Free Survival [ Time Frame: From the time of randomization of the first participant to the date of clinical cutoff (approximately 52 months) ]
    Concordance is presented as the percentage of participants with concordance between assessments. EFS concordance was defined as event Structural assessment and Diffusion Perfusion assessment occurs within 28 days or no event Structural and no Diffusion Perfusion.

  8. Health Status as Measured by the Health Utility Index (HUI) [ Time Frame: Baseline, Cycle 6 of the adjuvant phase, end of treatment (approximately 58 weeks post-baseline), and yearly during the follow-up period (maximum 5 years in follow-up) ]
    HUI is a preference-based, multi-attitude, health-related instrument specifically developed for use with children. HUI consists of eight attributes of health status: vision, hearing, speech, ambulation, dexterity, emotion, cognition and pain. Each attribute had 5 or 6 levels varying from highly impaired to normal. Each of the eight health dimensions was tested separately and a composite score ranging between 1 (perfect health) and 0 (death) was obtained for participants aged 5 years or older.

  9. Neurological Psychological Function as Measured by the Wechsler Scale [ Time Frame: End of treatment (approximately 58 weeks post-baseline) ]
    The Wechsler Intelligence Scale for Children version IV (WISC-IV) was used to generate a full scale intelligence quotient (IQ) which represents a child's general intellectual ability. The average IQ score is 100, with lower scores representing lower intellectual ability.

  10. Percentage of Participants Who Completed >/= 90% of Planned Radiotherapy and TMZ Administrations [ Time Frame: From the time of randomization of the first participant to the date of clinical cutoff (approximately 52 months) ]
  11. Percentage of Participants With a Treatment Delay or Discontinuation [ Time Frame: From the time of randomization of the first participant to the date of clinical cutoff (approximately 52 months) ]
  12. Number of Dose Administrations of Study Treatment in the Concurrent Phase [ Time Frame: Beginning of the concurrent phase to end of treatment break (10 weeks) ]
    Number of doses were assessed for the concurrent phase, which is the treatment period after the initial treatment phase and including the subsequent treatment break of approximately 4 weeks.

  13. Percentage of Participants With an Adverse Event (AE) [ Time Frame: From the time of randomization of the first participant to the date of clinical cutoff (approximately 52 months) ]
    An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
