|Condition or disease||Intervention/treatment|
|Malignant Gliomas||Drug: Gliolan® Procedure: Fluorescence-Guided Surgery|
- To determine whether Gliolan® (5-ALA)-induced PPIX fluorescence correlates with malignant tumor histopathology (in a minimum of 3-5 serial biopsies taken from the red fluorescent region of tissue resection).
- To determine the patient safety profile of both oral Gliolan® (5-ALA), as well as use of the fluorescence operative microscope. These will include use of commonly accepted toxicity measures as well as recording surgically-related neurological deficits within the six weeks after surgery.
- To determine functionality and performance reliability of the blue light excitation microscope platforms (Zeiss Pentero, Leica OH4, Leica OH6 and others).
- To correlate PPIX-containing extracellular microvesicles recovered from blood (at multiple time points prior to and following tumor resection) with the pre-operative MRI tumor volume.
- To characterize the presence and longitudinal changes in microvesicle biomarkers recovered from blood evaluating EGFRvIII, IDH1/2 wt and mutations and others. These microvesicular blood genes will be identified and correlated with the same microvesicular genes identified in tissue at the time of surgery.

Gliolan® is presented as a powder for oral solution in 60 ml colorless glass vials. The formulation contains 1.5 g 5-aminolevulinic acid hydrochloride corresponding to 1.17 g of 5-aminolevulinic acid. The oral solution is intended for single (partial) use.
single dose of oral 5-ALA (20mg/kg bodyweight) at 3 hours (range 2-5 hours) given preoperatively
Other Name: 5-ALA
Procedure: Fluorescence-Guided Surgery
performed utilizing blue light. At least 3-5 fluorescent tissue samples will be taken.

- Incidence of diagnostic tissue presence [ Time Frame: 6 weeks ]Pathologic confirmation of tumor type will be made by a pathologist who will not be informed of the fluorescence status of the tissue samples.
- Presence of malignant glioma tumor cells [ Time Frame: 6 weeks ]Pathologic confirmation of tumor type will be made by a pathologist who will not be informed of the fluorescence status of the tissue samples.
- WHO tumor type with grading [ Time Frame: 6 weeks ]Pathologic confirmation of tumor type will be made by a pathologist who will not be informed of the fluorescence status of the tissue samples.
- Ki-67 proliferation index [ Time Frame: 6 weeks ]Ki-67 is a prognostic marker for cancer
- Karnofsky Performance Scale [ Time Frame: 6 weeks ]Scale from 0-100, function from low to high, with 100 being normal
