Arm | Intervention/treatment |
---|---|
Experimental: intraoperative PDT 400J/cm² |
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). |
Experimental: intraoperative PDT 600J/cm² |
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). |
Experimental: intraoperative PDT 800J/cm² |
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). |
- Maximum Tolerated Dose-Light Level (MTDL) defined as the light dose associated with an acceptable dose-limiting toxicity level (TDL) [ Time Frame: 4 weeks (+/-3 days) post-PDT. ]Dose level above which TDL is observed in more than 33% (i.e., d̀-> 2 of 6) of subjects in an arm
- Progression Free Survival (PFS) [ Time Frame: From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months ]Number of patients without relapse within 25 mm of surgical site defined according to International RANO criteria
- Global Progression Free Survival (PFS) [ Time Frame: From the Date of diagnosis of glioblastoma until the date of Relapse, an average 18 months ]Median of progression-free survival time determined according to international RANO criteria
- Overall Survival (OS) [ Time Frame: From the Date of diagnosis of glioblastoma until the death, an average 18 months ]Median of OS determined according to international RANO criteria
- Response to treatment [ Time Frame: every 3 months between the Date of intraoperative PDT until relapse/death, an average 18 months ]Evaluated by MRI/ TEP 11C-MET every 3 months
- Incidence of "intraoperative PDT" treatment-emergent Adverse Events [ Time Frame: From the beginning of treatment with intraoperative PDT up to relapsing/death, an average 18 months ]Collection of all Adverse events (AEs and SAEs) (according to NCI-CTCE V5.0) and reviewing by an Independent Safety Monitoring Board
- Quality of Life Questionnaire -C30 ( QLQ-C30 [ Time Frame: Every 3 months from the signature of Consent form until relapse/death, an average 18 months ]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
- Quality of Life Questionnaire - Brain Cancer Module (QLQ-BN20) [ Time Frame: Every 3 months from the signature of Consent form until relapse/death, an average 18 months ]Measuring the health-related quality of life in patients with brain cancer
