Abstract

Disclosed are neuroblastoma tumor-initiating cell inhibiting compositions comprising chemical entities capable of affecting neuroblastoma tumor-initiating cells. Pharmaceutical preparations that include these chemical entities are also provided for the treatment of neuroblastoma. These pharmaceutical preparations are suitable for the treatment of humans, and are particularly suited for the treatment of children of 12 years of age or younger having neuroblastoma. The compositions and pharmaceutical preparations posses reduced normal cell cytotoxicity. The compositions and pharmaceutical preparations may be used alone or together with other conventional neuroblastoma preparations as part of a clinical regimen in the treatment and management of neuroblastoma.
