ArmTypeDescription
humanized anti-GD2 antibody, hu3F8, when combined with GM-CSFEXPERIMENTALOne cycle consists of treatment with hu3F8 at a dose of 2.4mg/kg/dose for 3 days (day 1, 3, and 5) in the presence of subcutaneous (sc) GM-CSF (day -4 through 5). These 3 doses of hu3F8 and 10 days of GM-CSF constitute a treatment cycle. Cycles are repeated at \~2-4 week intervals between first days of hu3F8, through 5 cycles. A maximum of 5 cycles will be administered on protocol. If elevations of amylase and/or lipase (\>Grade 1) or clinical signs suggestive of pancreatitis (e.g. upper abdominal pain) occurs, naxitamab and GM-CSF doses should be held until improvement of toxicity to ≤Grade 1 if laboratory elevations and/or pancreatitis is possibly related to either naxitamab or GM-CSF.
