Primary Outcome Measures:

  • Establish a safe dose to provide optimal discrimination between normal and malignant tissue for oral ALA administration intraoperatively [ Time Frame: participants will be followed while in the hospital and for 12 weeks after surgery ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

  • Compare time-to-progression and survival to that in comparable cases performed without the aid of ALA [ Time Frame: participants will be followed for 24 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 18
Study Start Date: October 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)


Assigned Interventions
Experimental: ALA

5-Aminolevuline Acid (ALA)
Drug: 5-Aminolevuline Acid

5-Aminolevuline Acid (ALA) at 30 mg/kg given orally 4 hours before surgery

Detailed Description:

This study aims to determine the safety and utility of using 5-Aminolevulinic Acid (ALA) in removing brain tumors during surgery. When ALA is provided at an increased concentration, protoporphorin concentration in the malignant cell increases and renders the cell fluorescent under long ultraviolet light. This study looks at using oral ALA to help identify the tumor cells intraoperatively and facilitate complete resection.

Oral ALA will be given prior to image-guided microsurgical resection of the tumor. Following tumor resection under light microscopy, the tumor bed will be illuminated and any residual fluorescent tissue in cavity will be surgically removed leading to a more complete resection of tumor. Pathologic confirmation of tumor type will be made by neuropathology. Photosensitizer concentration in malignant and normal tissue will be estimated by fluorescence microscopy.

  • Confirmation of Glial Tumor
  • Gross total resection is the aim of surgery
  • Ability to understand and the willingness to sign a written informed consent document or have a parent or guardian with the ability to understand and the willingness to sign a written informed consent.

Exclusion Criteria:

  • Non-Glial tumor i.e. tumor abscess, metastasis, lymphoma, vasculitis

  • Personal or family history of porphorias
  • Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
