Monoclonal Antibody 3F8 and Sargramostim in Treating Patients With Neuroblastoma

The total dosage of 3F8 per cycle is the same as in prior trials (100 mg/m2), administered at 20 mg/m2/day and infused over \~1.5 hr or less (0.5 hr is customary), with analgesics and antihistamines used as needed for expected side-effects. 3F8 is started \~1 hr after completion of GM-CSF administration. GM-CSF is dosed at 250 mcg/m2/day from day -5 to day +1 (Wednesday to Tuesday is customary) , and is 500 mcg/m2/day thereafter (i.e., on days +2 to +4; Wednesday to Friday), as in the predecessor protocol.18,74 Patients come off study if progressive disease occurs or if there is life-threatening grade 4 toxicity from 3F8; otherwise, patients will receive a minimum of 4 cycles of treatment and will continue treatment through 24 months. It is expected that patients will receive \~10 cycles.
