Selinexor in Treating Younger Patients With Recurrent or Refractory Solid Tumors or High-Grade Gliomas

NCT02323880

Description:

This phase I trial studies the side effects and best dose of selinexor in treating younger patients with solid tumors or central nervous system (CNS) tumors that have come back (recurrent) 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.

Purpose

This phase I trial studies the side effects and best dose of selinexor in treating younger patients with solid tumors or central nervous system (CNS) tumors that have come back (recurrent) 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.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To determine the recommended phase 2 dose (RP2D) or the maximum tolerated dose (MTD) of
      the tablet formulation of selinexor in children with recurrent/refractory solid and CNS
      tumors.

      II. To describe the toxicities of selinexor in children with recurrent/refractory solid and
      CNS tumors.

      III. To characterize the pharmacokinetics of the tablet formulation of selinexor in children
      with recurrent/refractory solid and CNS tumors.

      SECONDARY OBJECTIVES:

      I. To determine the antitumor effect of selinexor in a preliminary manner in children with
      recurrent/refractory solid and CNS tumors.

      II. To determine the pharmacodynamic properties of selinexor in children and adolescents with
      refractory solid tumors in plasma proteins and whole blood ribonucleic acid (RNA).

      III. To explore the penetration, pharmacodynamic effects, and biologic effects of selinexor
      in tumor tissue of patients with recurrent/refractory high-grade gliomas (HGG) requiring
      resection.

      IV. To further assess the toxicity and antitumor effects of selinexor in children with
      recurrent/refractory HGG in expanded cohorts following dose-escalation by measuring rate of
      objective radiographic response (medical patients) and rate of progression-free survival
      (PFS) six months from the start of treatment (surgical patients).

      OUTLINE: This is a dose escalation study.

      Patients receive selinexor orally (PO) once weekly (days 1, 8, 15, and 22). Treatment repeats
      every 28 days for up to 24 cycles in the absence of disease progression or unacceptable
      toxicity.

      After completion of study treatment, patients are followed up for 30 days.
