Sorafenib and Cyclophosphamide/Topotecan in Patients With Relapsed and Refractory Neuroblastoma
Phase: Phase 1
DFCI Protocol ID: 14-494
This study will combine three drugs: sorafenib, cyclophosphamide and topotecan. Adding sorafenib to cyclophosphamide and topotecan may increase the effectiveness of this combination. The investigators first need to find out the highest dose of sorafenib that can be given safely together with cyclophosphamide and topotecan. This is the first study to test giving these three drugs together and will help determine the highest dose of sorafenib that can safely be given together with cyclophosphamide and topotecan to patients with resistant/relapsed neuroblastoma.

partial response to frontline therapy after a minimum of 4 cycles of induction therapy AND
patient has never had recurrent/progressive disease.

a biopsy confirming neuroblastoma and/or ganglioneuroblastoma in at least one FDG-PET
avid site present at the time of enrollment done prior to enrollment and at least two
weeks subsequent to the most recent prior therapy.

prior to the start date for protocol therapy.
