Study start date: January 23, 2017

Actual date on which the first participant was enrolled.

The purpose of this study is to test see the combined effects of the study drug called Humanized 3F8 (Hu3F8) when used with granulocyte-macrophage colony stimulating factor (GM-CSF). Hu3F8 plus GM-CSF could prevent your neuroblastoma from growing, but it could also cause side effects.

Treatment Groups

Group I

Experimental
In this phase II single arm trial, patients with HR-NB in first CR or VGPR undergo consolidation by using hu3F8/GM-CSF x5 cycles and isotretinoin x6 cycles. Isotretinoin starts after cycle 2 of hu3F8/GM-CSF.
