Feasibility/Phase II Study of hu14.18-IL2 Immunocytokine + GM-CSF and Isotretinoin in Patients With Relapsed or Refractory Neuroblastoma
This phase II trial is studying how well hu14.18-interleukin-2 (IL2) fusion protein works when given together with sargramostim and isotretinoin in treating patients with relapsed or refractory neuroblastoma. Biological therapy, such as hu14.18-IL2 fusion protein, and sargramostim work in different ways to stimulate the immune system and stop tumor cells from growing. Drugs used in chemotherapy, such as isotretinoin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving hu14.18-IL2 fusion protein together with sargramostim and isotretinoin may kill more tumor cells.

Conditions
- Recurrent Neuroblastoma

- hu14.18-IL2 fusion protein
- isotretinoin
- sargramostim
- laboratory biomarker analysis
Primary outcomes
- Number of Patients With Unacceptable Dose Limiting Toxicities (DLTs) — Up to 10 courses
Test for tolerability and monitor for the occurrence of too many unacceptable DLTs using a two-stage stopping rule: (Stage 1) Accrue 10 patients. If more than 1 experience at least one unacceptable DLT during the first treatment cycle, the regimen will be considered to have unacceptable toxicity, and accrual will be temporarily closed, to review all relevant data and consider modifying the regimen to improve safety. If 1 or no patients have an unacceptable DLT in the first treatment cycle, then continue. (Stage 2) Accrue 20 more patients. If 7 or more experience at least one unacceptable DLT in the first treatment cycle, temporarily close the study for possible dosing-safety modifications. If 6 or fewer have an unacceptable DLT in the first treatment cycle, it is reasonable to assume that the combination therapy is safe.
