New light therapy targets deadly brain tumors during surgery

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion criteria I01. Males or females must be between 18, or legal age of consent, and 75 years of age (both included) at the time of signing informed consent. I02. Signed informed consent which includes compliance with requirements and restrictions listed in the informed consent. I03. Newly diagnosed GBM, presumed on the basis of clinical and MRI criteria (intra-axial brain tumor with peripheral rim contrast enhancement). I04. Karnofsky Performance Score ≥70 I05. Eligible for surgery. I06. Amenable to maximal tumor resection based on MRI. I07. Planned to receive SOC (i.e., Stupp Protocol) treatment after surgery. I08. Ability to take oral medications. I09. Tumor eligible to PDT procedure as validated by both investigator and sponsor based on pre-operative MRI data Exclusion criteria 1.Medical conditions E01. 1. Patient with bifocal or multifocal disease, assessed on MR1I T1Gd enhanced. 2. Patient with tumor of deep location such as tumor involving the corpus callosum, the basal ganglia, the brain stem, or tumor involving the midline as assessed on MRI. 3. Patient with prior brain surgery other than stereotactic biopsy E02. Patient with Lynch syndrome E03. Patient with Li-Fraumeni syndrome E04. Debilitating cardiopulmonary disease, unstable Type 1 or Type 2 diabetes (treated or not) E05.

Clinically significant abnormal ECG results, including a corrected QT interval QTc \> 480 ms E07. Creatinine clearance \< 60 mL/min E08. Severe hepatic impairment (bilirubin \> 1.5 x the upper limit of normal \[ULN\] or alkaline phosphatase or transaminases (AST, ALT) \> 2.5 x ULN) E09. Known allergic reactions to silicone E10. Known allergic reactions or hypersensitivity to egg, soya, or peanut proteins. E11. Febrile illness Contraindication E12. Contraindication to 5-ALA HCl administration, including: 1. Porphyria 2. Taking photosensitizing drugs 24 hours before and 14 days after the administration of Pentalafen® including but not limited to: St. John's wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulphonamides, quinolones and tetracyclines, and topical preparations containing ALA (See Section 6.10) 3. Inability to suspend a long-term hepatotoxic treatment (such as, but not limited to diclofenac, fenofibrate, carbamazepine) for 24 hours after 5-ALA HCl intake E13. Contraindication to MRI examination (e.g., MRI-incompatible pacemaker) E14. Treatment with another investigational drug or intervention within 30 days prior to or during the entire study
