A Phase 1 Study of Selinexor (KPT-330), a Selective XPO1 Inhibitor, in Recurrent and Refractory Pediatric Solid Tumors, Including CNS Tumors

This phase I trial studies the side effects and best dose of selinexor in treating younger patients with solid tumors or high-grade gliomas that have come back (recurred) or do not respond to treatment (refractory). Drugs used in chemotherapy, such as selinexor, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
