RATIONALE: Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances, such as radioactive iodine, to them without harming normal cells.

PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody after radiation therapy in treating patients with newly diagnosed primary brain tumors that can be surgically resected.

Condition Intervention Phase
Brain and Central Nervous System Tumors
Drug: carmustine
Drug: irinotecan hydrochloride
Procedure: surgical procedure
Radiation: iodine I 131 monoclonal antibody 81C6
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment

Official Title: Phase I Study of Anti-Tenascin Monoclonal Antibody I-Labeled 81C6 Via Surgically Created Cystic Resection Cavity in the Treatment of Patients With Primary Brain Tumors After External Beam Radiotherapy

Detailed Description:


  • Determine the toxicity of iodine I 131 monoclonal antibody 81C6 delivered via the intracranial resection cavity in patients with newly diagnosed primary malignant brain tumors after surgery and radiotherapy.
  • Determine objective therapeutic responses of these patients to this treatment.

OUTLINE: This is a dose escalation study of iodine I 131 antitenascin monoclonal antibody 81C6 (I 131 MAb 81C6).

Within 2-4 weeks after completion of external beam radiotherapy, patients undergo surgical resection of the tumor or brain metastasis, at which time an indwelling intracranial resection cavity catheter is placed. A single dose of I 131 MAb 81C6 is delivered via the intralesional catheter.

Cohorts of 3-6 patients receive escalating doses of I 131 MAb 81C6 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities.

After the MTD has been established, patients in the phase II portion of the study receive therapy as in phase I.

Beginning 4 weeks after the monoclonal antibody treatment, patients begin chemotherapy. Patients receive carmustine IV over 1 hour on day 1 and irinotecan IV over 90 minutes once weekly for 4 weeks. Treatment is repeated every 6 weeks for at least 4 courses in the absence of disease progression.

Patients are followed initially at 4 weeks, then every 6 weeks for 1 year.

PROJECTED ACCRUAL: A total of 41 patients will be accrued for this study.
