Brief Summary: RATIONALE LMB-7 immunotoxin can locate tumor cells and kill them without harming normal cells
PURPOSE Phase I trial to study the effectiveness of LMB-7 immunotoxin in treating patients who have leptomeningeal metastases metastases
Detailed Description: OBJECTIVES I Determine the toxicity of intrathecal LMB-7 immunotoxin in patients with leptomeningeal metastases II Identify objective therapeutic responses in this group of patients
OUTLINE This is a dose escalation study Patients receive LMB-7 intrathecally on days 1 3 and 5 Treatment may be repeated every 4 weeks if the patient does not demonstrate HAMA neutralizing antibodies to PE-38 in CSF has stable or responding disease and has not experienced greater than grade II toxicity Three to six patients are entered at each dose level Dose escalation continues until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which 2 of 6 patients experience grade 3 or worse toxicity or a neuroradiology toxicity score of 10 or greater
PROJECTED ACCRUAL Approximately 15 to 24 patients will be accrued over one year
