Clinical Trial 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.

• Glioblastoma

Intervention

Drug:
• Gliolan
patient will receive 5-ALA 4 to 6 hours before surgery

Device:
• Intraoperative PDT
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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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., d`-> 2 of 6) of subjects in an arm	4 weeks (+/-3 days) post-PDT.
Secondary	Progression Free Survival (PFS)	Number of patients without relapse within 25 mm of surgical site defined according to International RANO criteria	From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months
Secondary	Global Progression Free Survival (PFS)	Median of progression-free survival time determined according to international RANO criteria	From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months
Secondary	Overall Survival (OS)	Median of OS determined according to international RANO criteria	From the Date of diagnosis of glioblastoma until the death, an average 18 months
Secondary	Response to treatment	Evaluated by MRI/ TEP 11C-MET every 3 months	every 3 months between the Date of intraoperative PDT until relapse/death, an average 18 months
Secondary	Incidence of "intraoperative PDT" treatment-emergent Adverse Events	Collection of all Adverse events (AEs and SAEs) (according to NCI-CTCE V5.0) and reviewing by an Independent Safety Monitoring Board	From the beginning of treatment with intraoperative PDT up to relapsing/death, an average 18 months
Secondary	Quality of Life Questionnaire -C30 ( QLQ-C30	The QLQ-C30 is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, a global health status / QoL scale, and six single items	Every 3 months from the signature of Consent form until relapse/death, an average 18 months
Secondary	Quality of Life Questionnaire - Brain Cancer Module (QLQ-BN20)	Measuring the health-related quality of life in patients with brain cancer	Every 3 months from the signature of Consent form until relapse/death, an average 18 months
