Brief Summary:

RATIONALE: Giving boron phenylalanine in different ways and measuring it in tissue in patients with glioblastoma multiforme may help in planning better radiation therapy, such as boron neutron capture therapy, for patients in the future.

PURPOSE: This phase I trial is studying the side effects, best dose boron phenylalanine, and best way of giving it with or without mannitol in treating patients with glioblastoma multiforme.

Condition or disease Intervention/treatment Phase
Brain and Central Nervous System Tumors Drug: boron phenylalanine Drug: mannitol Other: biologic sample preservation procedure Radiation: radiation therapy treatment planning/simulation Phase 1

Detailed Description:



  • To determine the optimal way to deliver boron phenylalanine (BPA) with or without mannitol in terms of route (intravenous vs intraarterial), blood-brain barrier disruption, and dose for use in subsequent therapeutic trials of boron neutron capture therapy (BNCT) in patients with high-grade glioma.
  • To evaluate the toxicity profile of BPA administered intravenously or intra-arterially.
  • To evaluate the pharmacokinetic behavior of BPA using samples of blood, urine, tumor tissue, normal brain tissue, extracellular fluid, and cerebrospinal fluid.


  • To produce indicative treatment plans using BPA administered either intravenously or intra-arterially with or without mannitol to support the design of combination studies using BPA and thermal neutrons for BNCT.


  • To evaluate the micro-distribution of boron resulting from the different routes of administration using secondary ion mass spectroscopy (SIMS).
  • To store surplus tissues removed during the trial for possible future studies.

OUTLINE: This is a dose-escalation study.

  • Stage 1 (Route and Blood Brain Barrier Disruption [BBBD]): Patients receive one dose of boron phenylalanine intravenously (IV) or intra-arterially (IA) over 2 hours. Some patients may receive mannitol IA over 30 seconds before receiving boron phenylalanine. Patients then undergo planned biopsy of the tumor. Some patients may then undergo immediate surgical debulking of the tumor.

Boron distribution data is analyzed to determine the optimal administration schedule. Patients in stage 2 receives boron phenylalanine via the optimal route established in stage 1. If addition of mannitol is found to be beneficial, then mannitol is used in stage 2

  • Stage 2 (Dose-escalation): Patients receive 1 or 2 doses of boron phenylalanine IV or IA (as determined in stage 1) over 2 hours on day 1. Patients may also receive mannitol IA as in stage 1.

Tumor tissue, normal brain tissue, and cerebrospinal fluid are collected during biopsy and/or surgery. Some patients undergo blood, urine, extracellular fluid sample collection periodically for pharmacokinetic studies. Tumor tissue will be stored for future studies.

After completion of study treatment, patients are followed for 7 days and then once a month.

Primary Outcome Measures :
  1. Optimal dose of boron phenylalanine (BPA)
  2. Causality of each adverse event to BPA and grading severity according to NCI CTCAE Version 3.0
  3. Pharmacokinetic (PK) parameters used to construct a PK model with the aim of being able to predict boron up-take by tumor and normal brain tissue

Secondary Outcome Measures :
  1. Change in mean dose to the planning target volume of greater than 15%, for a constant maximum and mean dose to normal tissue in any treatment cohort of the study
  2. Change in the intra-nuclear percentage of 10B atoms in any cohort of the study of greater than 20%
  3. Establishment of a repository of samples including serum and tumor tissue for future studies using techniques such as proteomics and DNA array
