Safety Study of Aminolevulinic Acid (ALA) to Enhance Visualization and Resection of Tumors of the Brain

Stopped early · Phase 2

Conditions studied: Glioma

In brief

The prodrug, 5-Aminolevulinic acid (ALA), has been shown to lead to intracellular accumulation of fluorescent porphyrins in high grade malignant gliomas in the brain. On imaging, this accumulation of fluorescent porphyrins helps delineate tumor borders, resulting in the surgeon being better able to visualize and thus able to make a complete, or near-complete resection of the tumor.

Who can join

Age: 18 and older, up to 72. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Presumptive diagnosis of high grade or low grade glioma based on imaging studies, or will have recurrent high-grade or low grade gliomas that have previously undergone diagnosis (astrocytoma, oligodendroglioma, mixed oligo-astrocytoma, anaplastic astrocytoma, and glioblastoma multiforme). Both of these groups will be undergoing craniotomy for tumor resection.
• Patient age 18 to 72 years.
• Karnofsky performance of 60% or greater
• Patients must have normal organ and marrow function as defined below:
• Leukocytes >3,000/μL Absolute neutrophil count >1,500/μL Platelets >100,000/μL Total bilirubin within normal institutional limits AST (SGOT)/ALT (SGPT) <2.5 X institutional upper limit of normal Creatinine within normal institutional limits or Creatinine clearance ≥60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
• The effects of Aminolevulinic Acid (ALA) on the developing human fetus are unknown. Therefore, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
• Patient must have the 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 the written informed consent.

You may not qualify if…

• Subjects with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to aminolevulinic acid (ALA).
• Subjects with a history or family history of Porphyrias
• Subjects with 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.
• Pregnancy.
