Brief Summary
The phase II study evaluate a light dose escalation in a classical intraoperative PDT regimen mediated by 5-ALA-PpIX, in glioblastoma patients with access to full surgical removal of the contrast enhancement. This treatment will be performed in addition to the current reference treatment of glioblastoma: maximum removal surgery followed by radiochemotherapy according to the Stupp protocol.

Outcome Measures
Primary Outcomes (1)
Maximum Tolerated Dose-Light Level (MTDL) defined as the light dose associated with an acceptable dose-limiting toxicity level (TDL)
Dose level above which TDL is observed in more than 33% (i.e., d̀-\> 2 of 6) of subjects in an arm
4 weeks (+/-3 days) post-PDT.
Secondary Outcomes (7)
Progression Free Survival (PFS)
From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months
Global Progression Free Survival (PFS)
From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months
Overall Survival (OS)
From the Date of diagnosis of glioblastoma until the death, an average 18 months
Response to treatment
every 3 months between the Date of intraoperative PDT until relapse/death, an average 18 months
Incidence of "intraoperative PDT" treatment-emergent Adverse Events
From the beginning of treatment with intraoperative PDT up to relapsing/death, an average 18 months
- +2 more secondary outcomes

EXPERIMENTALInterventions
patient will receive 5-ALA 4 to 6 hours before surgery
The protocol requires the realization of specific procedures in addition to the usual care. The intra-operative photodynamic therapy ("intraoperative PDT") added to surgery for glioblastoma excision. The patient will receive 5-ALA ( 5-aminolevulinic acid hydrochloride),GLIOLAN drinkable 6h before surgery + lighting of the tumor bed by a red light source (laser with different J/cm²) at the end of resection (Prolonged surgery of 45 minutes).
