PRIMARY OBJECTIVES:

I. To assess the safety and toxicity of intratumoral and resection cavity administration of an Edmonston's strain measles virus genetically engineered to produce CEA (MV-CEA) in patients with recurrent glioblastoma multiforme.

II. To determine the maximum tolerated dose (MTD) of MV-CEA. III. To characterize viral gene expression at each dose level as manifested by CEA titers.

IV. To assess viremia, viral replication, and measles virus shedding/persistence following intratumoral administration.

V. To assess humoral and cellular immune response to the injected virus. VI. To assess in a preliminary fashion antitumor efficacy of this approach.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 sequential treatment arms.

ARM A (RESECTION CAVITY ADMINISTRATION): Patients undergo en block resection of their tumor (after confirming diagnosis) on day 1, followed by MV-CEA administered into the resection cavity.

ARM B (INTRATUMORAL AND RESECTION CAVITY ADMINISTRATION): Patients undergo stereotactic biopsy (to confirm the diagnosis) and placement of a catheter within the tumor, followed by carcinoembryonic antigen-expressing measles virus intratumorally (IT) through the catheter over 10 minutes on day 1. Patients then undergo en block resection of their tumor with computer-assisted stereotactic techniques on day 5, followed by MV-CEA administered around the tumor bed.

After completion of study treatment, patients are followed up at 28 days (non-cohort I patients), 7 weeks (patients in cohort I only), every 2 months until progression, every 3 and 12 months after progression, and then yearly thereafter for up to 15 years.
