Phase 2
Recruiting
Conditions
Glioblastoma
Interventions
Device: Intraoperative PDT
Registration Number
NCT04391062
Lead Sponsor
University Hospital, Lille
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.

Primary Outcome Measures
NameTimeMethod
Maximum Tolerated Dose-Light Level (MTDL) defined as the light dose associated with an acceptable dose-limiting toxicity level (TDL)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

Secondary Outcome Measures
NameTimeMethod
Progression Free Survival (PFS)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)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

Quality of Life Questionnaire -C30 ( QLQ-C30Every 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

Overall Survival (OS)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 treatmentevery 3 months between the Date of intraoperative PDT until relapse/death, an average 18 months

Evaluated by MRI/ TEP 11C-MET every 3 months

Quality of Life Questionnaire - Brain Cancer Module (QLQ-BN20)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

Incidence of "intraoperative PDT" treatment-emergent Adverse EventsFrom 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
