Brief Summary:
INTRAGO II resembles a multicentric, prospective, randomized, 2-arm, open-label clinical phase III trial which tests if the median progression-free survival (PFS) of patients with newly diagnosed glioblastoma multiforme (GBM) can be improved by the addition of intraoperative radiotherapy (IORT) to standard radiochemotherapy.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: Experimental Arm (A)
Standard surgery plus intraoperative radiotherapy (20-30 Gy) followed by radiochemotherapy (EBRT: 60 Gy, 75 mg/m2/d temozolomide) and adjuvant chemotherapy with 150-200 mg/m2/d temozolomide per cycle (5/28 days).
Procedure: Standard surgery (neuronavigation-guided)
Radiation: Intraoperative radiotherapy
Dose to applicator surface: 20-30 Gy; Carl Zeiss INTRABEAM System. IORT with a surface dose of 30 Gy is recommended.Should the proximity to any risk structure not allow to apply 30 Gy, a dose reduction by up to 10 Gy (resulting in a surface dose of 20 Gy) is allowed.
Other Name: IORT

Radiation: Radiochemotherapy
EBRT to 60 Gy plus 75 mg/m2/d temozolomide

Drug: Temozolomide
Adjuvant chemotherapy with 150-200 mg/m2/d temozolomide per cycle (5/28 days).

Active Comparator: Control Arm (B)
Standard surgery followed by radiochemotherapy (EBRT: 60 Gy, 75 mg/m2/d temozolomide) and adjuvant chemotherapy with 150-200 mg/m2/d temozolomide per cycle (5/28 days).

Primary Outcome Measures :
  1. Median Progression-Free Survival [ Time Frame: 24 Months ]
    Determined according to modified Response Assessment in Neuro-Oncology (RANO) criteria and serial perfusion imaging


Secondary Outcome Measures :
  1. Median Overall Survival [ Time Frame: 24 Months ]
  2. PFS within a 1-2 cm margin around the cavity [ Time Frame: 24 Months ]
    Determined by serial contrast-enhanced MRI scans using modified RANO criteria and serial perfusion imaging

  3. OS with respect to Age [ Time Frame: 24 Months ]
    Median overall survival of patients <65 vs. ≥ 65 years

  4. PFS with respect to Age [ Time Frame: 24 Months ]
    Progression-free survival of patients <65 vs. ≥ 65 years; determined according to modified RANO criteria and serial perfusion imaging

  5. OS with respect to KPS [ Time Frame: 24 Months ]
    Median overall survival of patients with KPS 80-100% vs. 60-70%

  6. PFS with respect to KPS [ Time Frame: 24 Months ]
    Progression-free survival of patients with KPS 80-100% vs. 60-70%; determined according to modified RANO criteria and serial perfusion imaging

  7. OS with respect to thickness of anticipated T1-Gd-enhancing (remaining) tumor margin [ Time Frame: 24 Months ]
    Thickness of anticipated T1-Gd-enhancing (remaining) tumor margin as per the discretion of the surgeon (margin ≥0.5 cm or multiple spots of residual tumor within the cavity vs. <0.5 cm)

  8. PFS with respect to thickness of anticipated T1-Gd-enhancing (remaining) tumor margin [ Time Frame: 24 Months ]
    Thickness of anticipated T1-Gd-enhancing (remaining) tumor margin as per the discretion of the surgeon (margin ≥0.5 cm or multiple spots of residual tumor within the cavity vs. <0.5 cm); determined according to modified RANO criteria and serial perfusion imaging

  9. OS with respect to extent of resection [ Time Frame: 24 Months ]

    Early postoperative MRI scans must be used to determine the extent of resection (EoR). The EoR is given as sum of all maximum diameters of residual lesions in cm. OS will be calculated for the following groups:

    • Max Diameter group 0: 0 cm (no residual tumor)
    • Max Diameter group 1: >0 to ≤1.5 cm (cumulative if multiple residual lesions)
    • Max Diameter group 2: >1.5 cm (cumulative if multiple residual lesions)

  10. PFS with respect to extent of resection [ Time Frame: 24 Months ]

    Early postoperative MRI scans must be used to determine the extent of resection (EoR). The EoR is given as sum of all maximum diameters of residual lesions in cm. PFS will be determined according to modified RANO criteria and serial perfusion imaging for the following groups:

    • Max Diameter group 0: 0 cm (no residual tumor)
    • Max Diameter group 1: >0 to ≤1.5 cm (cumulative if multiple residual lesions)
    • Max Diameter group 2: >1.5 cm (cumulative if multiple residual lesions)

  11. OS with respect to MGMT promoter methylation status [ Time Frame: 24 Months ]
    OS in patients with promoter methylation vs. no promoter methylation

  12. PFS with respect to MGMT promoter methylation status [ Time Frame: 24 Months ]
    PFS in patients with promoter methylation vs. no promoter methylation; determined according to modified RANO criteria and serial perfusion imaging

  13. Quality of Life (QoL) questionnaire [ Time Frame: 24 Months ]
    Assessed by European Organization for Research and Treatment (EORTC)- Quality of Life Questionnaires (QLQ C30/BN20)

  14. Activities of daily living (ADL), assessed using the Barthel Index (Mahoney & Barthel, 1965). [ Time Frame: 24 Months ]
    Change in functional outcomes as measured by BI from its baseline value.

  15. Radiation-related (acute / early delayed / late) neurotoxicity [ Time Frame: 24 Months ]
    Assessed by regular neurological examinations and serial MRI scans
