RATIONALE: Radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody TNT-1/B (^131I MOAB TNT-1/B), can find tumor cells and carry tumor-killing substances to them without harming normal cells. This may be an effective treatment for glioblastoma multiforme.

PURPOSE: This phase I trial is studying the side effects and best dose of ^131I MOAB TNT-1/B in treating patients with progressive or recurrent glioblastoma multiforme.

Secondary Outcome Measures:
  • Biodistribution and radiation dosimetry by blood, urine, and whole body scans daily for 10 days [ Designated as safety issue: No ]
  • Toxicity by CTCAE v3.0 weekly for 12 weeks then every 8 weeks [ Designated as safety issue: Yes ]
  • Overall survival, median time of survival, and percent alive at 6 months [ Designated as safety issue: No ]

Estimated Enrollment: 22
Study Start Date: October 2005
Study Completion Date: October 2007
Detailed Description:



  • Determine the maximum tolerated dose of iodine I 131 monoclonal antibody TNT-1/B in patients with progressive or recurrent glioblastoma multiforme.


  • Determine the biodistribution and radiation dosimetry of this drug in these patients.
  • Determine the toxicity and tolerability of this drug in these patients.
  • Determine the overall survival, median time of survival, and 6-month survival of patients treated with this drug.

OUTLINE: This is an open-label, multicenter, dose-escalation study of therapeutic doses of iodine I 131 monoclonal antibody TNT-1/B (^131I MOAB TNT-1/B).

The first 12 patients accrued to the study undergo stereotactic placement of 2 catheters within the contrast-enhancing tumor on day 0. These patients then receive an imaging dose of ^131I MOAB TNT-1/B interstitially over approximately 25 hours on day 1 followed by dosimetry, biodistribution evaluations, and whole body imaging over an 8-10 day period. Beginning at least 2 weeks, but no more than 4 weeks later, all patients undergo catheter placement as above. One day later, patients receive a therapeutic dose of ^131I MOAB TNT-1/B interstitially over approximately 25 hours.

Cohorts of 3-6 patients receive escalating therapeutic doses of ^131I MOAB TNT-1/B until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. An additional 10 patients are treated at the MTD.

After completion of study treatment, patients are followed weekly for 3 weeks, at 6 weeks, at 4, 8, and 12 weeks (for the first 12 patients accrued to the study), every 4 weeks until disease progression, and then every 8 weeks thereafter.

PROJECTED ACCRUAL: Approximately 22 patients will be accrued for this study.
