The main goal of this study is to evaluate and to determine the dose of a highly accurate irradiation (allowing to increase the dose delivered while restricting the risk of complication) in association with temozolomide.

Condition Intervention Phase
Glioblastoma Radiation: radiotherapy Drug: temozolomide Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Further study details as provided by Centre Georges Francois Leclerc:

Primary Outcome Measures:
  • To determine the OTR (optimal tolerated regimen) of radiotherapy administered in combination with temozolomide as first-line therapy in patients with de novo glioblastoma [ Time Frame: 3 months after the start of the radiotherapy ]

Enrollment: 10
Study Start Date: September 2009
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: radiotherapy + temozolomide


dose given at PTV-g will be 70 Gy/28 fractions level 1 75 Gy/30 fractions level 2 80 Gy/32 fractions level 3

dose given at PTV-a will be 56 Gy/28 fractions level 1 60 Gy/30 fractions level 2 60.8 Gy/32 fractions level 3


temozolomide given at the dose of 75mg/m2

Radiation: radiotherapy
patients will receive from 6 to 7 weeks 5 days a week radiations. The dose of radiation will depend on the level they will be included.
Drug: temozolomide
patient will receive whatever the level 7 days a week, temozolomide at the dose of 75mg/m2 during radiotherapy period. They will then follow one month after the end the radiochemotherapy an adjuvant treatment corresponding to a 5 days treatments of temozolomide at the dose of 200mg/m2 every 28 days.
