Scientific titleRandomised phase II study evaluating a carbon ion boost applied after combined radiochemotherapy with temozolomide versus a proton boost after radiochemotherapy with temozolomide in patients with primary glioblastoma
Study acronymCLEOPATRA
Study hypothesisThe purpose of the trial is to compare a carbon ion boost to a proton boost delivered to the macroscopic tumour after combined radiochemotherapy (RT) with temozolomide (TMZ) in patients with primary glioblastoma multiforme (GBM). The aim of the study is to compare overall survival as a primary endpoint, and progression free survival, toxicity and safety as secondary endpoints.
Ethics approval(s)Ethics Committee of the Medical Faculty of Heidelberg (Ethikkommission der Medizinischen Fakultät Heidelberg) approved on the 2nd of November 2009
ConditionPrimary glioblastoma
InterventionArm A – Experimental Arm
Carbon Ion Radiation Therapy as a Boost to the macroscopic tumour
Total Dose 18 Gy E, 6 fractions, 3 Gy E single dose

Arm B – Standard Arm
Proton Radiation Therapy as a Boost to the macroscopic tumour
Total Dose 10 Gy E, 5 fractions, 2 Gy E single dose

In both treatment arms, the minimum follow-up will be 12 months after study treatment (for the last patient included). All other patients will be followed until 12 months after the last patient was included or until death.
