Boron Phenylalanine With or Without Mannitol in Treating Patients With Glioblastoma Multiforme

October 7, 2013 updated by: Cancer Research UK

A Cancer Research UK Pharmacokinetic Study of BPA in Patients With High Grade Glioma to Optimize Uptake Parameters for Clinical Trials of BNCT

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.

Detailed Description

OBJECTIVES:

Primary

  • 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.

Secondary

  • 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.

Tertiary

  • 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.
