NCT05099003

Brief Summary

This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink tumors in this patient population. Glioma is a type of cancer that occurs in the brain or spine. Glioma is considered high risk (or high-grade) when it is growing and spreading quickly. The term, risk, refers to the chance of the cancer coming back after treatment. DIPG is a subtype of HGG that grows in the pons (a part of the brainstem that controls functions like breathing, swallowing, speaking, and eye movements). This trial has two parts. The only difference in treatment between the two parts is that some subjects treated in Part 1 may receive a different dose of selinexor than the subjects treated in Part 2. In Part 1 (also called the Dose-Finding Phase), investigators want to determine the dose of selinexor that can be given without causing side effects that are too severe. This dose is called the maximum tolerated dose (MTD). In Part 2 (also called the Efficacy Phase), investigators want to find out how effective the MTD of selinexor is against HGG or DIPG. Selinexor blocks a protein called CRM1, which may help keep cancer cells from growing and may kill them. It is a type of small molecule inhibitor called selective inhibitors of nuclear export (SINE). Radiation therapy uses high energy to kill tumor cells and shrink tumors. The combination of selinexor and radiation therapy may be effective in treating patients with newly-diagnosed DIPG and H3 K27M-Mutant HGG.

Outcome Measures

Primary Outcomes (4)

  • Maximum tolerated dose

    Defined as the highest dose of selinexor in combination with standard of care radiation therapy (RT) that does not cause unacceptable side effects.

    From day 1 of selinexor treatment until the start of maintenance therapy, assessed up to 10 weeks from treatment start date

  • Event free survival (EFS)

    Will be calculated for diffuse midline glioma (DMG)/ high grade glioma (HGG) patients. EFS curve will be estimated by Kaplan Meier estimates.

    From the date of enrollment until disease progression date, secondary malignant neoplasm occurrence date, death date of any cause, or last follow-up date, assessed up to 5 years

  • Overall Survival (OS)

    Will be calculated for diffuse intrinsic pontine glioma (DIPG) patients. The OS curve will be estimated by Kaplan Meier estimates.

    From the date of enrollment until death date of any cause or last follow-up date, assessed up to 5 years

  • Overall response rate (ORR)

    Defined as the proportion of patients whose best response is partial response or complete response.

    Up to 5 years

Study Arms (1)

Treatment (selinexor and radiation therapy)

EXPERIMENTAL

CHEMORADIOTHERAPY: Patients receive standard of care radiation therapy 5 days per week for 5-7 weeks. Starting on day 4 or 5 of radiation therapy, patients receive selinexor PO on 1, 8, 15, 22, 29, 36, 43, and 50 in the absence of disease progression or unacceptable toxicity. After a 2-week rest period, patients proceed to Maintenance. Patients undergo a MRI and may undergo a biopsy during screening. MAINTENANCE: Patients receive selinexor PO on days 1, 8, 15, and 22 of each cycle. Cycles repeat every 28 days for up to 24 cycles of maintenance therapy in the absence of disease progression or unacceptable toxicity. Patients undergo a MRI on study and during follow-up.
