Study Details

Study Description

Brief Summary

This Phase One pediatric trial seeks to take advantage of the susceptibility of neuroblastoma to proteasome inhibitors, proven in vitro, along with the proven in vitro synergy of bortezomib with irinotecan and the successful Phase One pediatric trials of bortezomib to create a treatment using these two drugs in combination to treat refractory/recurrent neuroblastoma in children and young adults 25 and under.

Condition or Disease	Intervention/Treatment	Phase
Neuroblastoma	Drug: Irinotecan and Bortezomib	Phase 1

Detailed Description

In spite of intensive treatment including high-dose chemotherapy with autologous peripheral stem cell transplantation and radiation therapy, the long-term survival of patients with high-risk neuroblastoma remains poor. Patients who experience a relapse of their disease or fail to achieve complete remission fare even worse. More intense chemotherapy is not the answer. The development of new drugs with different mechanisms of action are required.

Inhibitors of the proteasome have created a considerable interest in their use in cancer chemotherapy, either as a single agent or in combination with other chemotherapeutic agents. The precise mechanism of action for these class of drugs is unclear, however, inhibition of I-kB degradation by VELCADE® (bortezomib) decreases NF-kB activity in neuroblastoma cell lines as well as other systems.

Previous studies have reported the activity of Irinotecan, a strong Topoisomerase-I inhibitor, against murine xenografts including those with high-risk features such as MYCN gene amplification (MYCN is also called V-Myc Myelocytomatosis Viral Related Oncogene, Neuroblastoma Derived). Irinotecan has also been shown to be active against neuroblastoma xenografts resistant to vincristine, melphalan, and topotecan, suggesting an alternative mechanism of resistance to Irinotecan. In vitro synergy between bortezomib and irinotecan has been documented in pancreatic cancer by others and in neuroblastoma by our group.

Outcome Measures

Primary Outcome Measures

Determine highest dose of IV irinotecan administered in conjunction with bortezomib without causing severe side effects. [3 years]

Secondary Outcome Measures
