Brief Summary

This trial studies how well fimepinostat works in treating patients with newly diagnosed diffuse intrinsic pontine glioma, or medulloblastoma, or high-grade glioma that have come back. Fimepinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVES:

I. To confirm penetration of fimepinostat across the blood brain barrier (BBB) in children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG), recurrent medulloblastoma, or recurrent high-grade glioma (HGG) by measuring concentration of fimepinostat and metabolite in primary tumor tissue.

EXPLORATORY OBJECTIVES:

I. To assess pharmacokinetics (PK) of fimepinostat in plasma and tumor tissue of children and young adults with newly diagnosed DIPG, recurrent medulloblastoma, or recurrent HGG.

II. To assess pharmacodynamics (PD) of fimepinostat in children and young adults with newly diagnosed DIPG, recurrent medulloblastoma, or recurrent HGG as measured by phosphorylation and acetylation in tumor tissue.

III. To correlate acetylation and phosphorylation in tumor tissue with tissue and plasma PK levels.

IV. To assess the safety and tolerability of fimepinostat in children and young adults with newly diagnosed DIPG, recurrent medulloblastoma, or recurrent HGG.

V. To assess preliminary efficacy of fimepinostat given as monotherapy after surgery in children and young adults with newly diagnosed DIPG, recurrent medulloblastoma, or recurrent HGG, as based on progression-free survival (PFS) and objective response rate (ORR) as appropriate.

OUTLINE:

Patients receive fimepinostat orally (PO) once daily (QD) on days -2 to 0. Within 2 hours of receiving fimepinostat on day 0, patients undergo tumor resection.

MAINTENANCE PHASE: Patients receive fimepinostat by mouth, once daily for days 1-5 each week. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 12 months from the time treatment begins. Should patients continue to derive clinical benefit, and not experience excess toxicity or progression, patients can continue to receive drug for up to 24 months or longer pending discussion with study chairs and study sponsor.

After completion of study treatment, patients are followed up at 30 days, then every 3 months for up to 5 years.

Study Groups

Treatment (fimepinostat, tumor resection)

Patients receive fimepinostat by mouth once daily, on Days -2 to 0. Within 2 hours of receiving fimepinostat on Day 0, patients undergo tumor resection or biopsy as part of their standard of care.

MAINTENANCE PHASE: Patients receive fimepinostat by mouth, once daily for days 1-5 each week. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 12 months from the time treatment begins. Should patients continue to derive clinical benefit, and not experience excess toxicity or progression, patients can continue to receive drug for up to 24 months or longer pending discussion with study chairs and study sponsor.

Eligibility Criteria

Inclusion Criteria

• Patients must have one of the following histologically confirmed diagnoses (histologic confirmation from initial diagnosis acceptable, as appropriate):

• Stratum A: Newly diagnosed diffuse intrinsic pontine glioma (WHO grade II-IV) - this stratum does not require tissue confirmation at time of enrollment, but diagnostic confirmation will be required to continue on study after biopsy. Patients with newly diagnosed DIPG will be eligible to enroll before or after standard of care radiation, but must be eligible for a biopsy. Newly diagnosed DIPG stratum should not have received prior therapy before the initiation of fimepinostat, with the exception of those patients who received temozolomide during radiation therapy or who previously received radiation as per standard of care and have not yet undergone a biopsy. All patients who have received therapy other than radiation and temozolomide should be discussed with study chair(s) prior to enrollment. Patients enrolling after standard of care radiation must be enrolled within 14 weeks of completion of radiotherapy.
• Stratum B: Recurrent medulloblastoma (WHO grade IV), any molecular subtype
• Stratum C: Recurrent high-grade glioma (HGG), including anaplastic astrocytoma (WHO grade III) and glioblastoma (WHO grade IV)

• Stratum B & C: Patients in the recurrent medulloblastoma or recurrent HGG arm can have locally recurrent or disseminated disease, provided resection/biopsy would still be clinically indicated. Disseminated disease can be diagnosed by imaging or Cerebrospinal fluid (CSF) cytology. Recurrent DIPG will be eligible for stratum C; however, eligibility requires biopsy/resection is feasible in a region of tumor outside of the pons (i.e. cerebellar extension or new metastatic site). These patients should be discussed with study chair(s) prior to enrollment
• Patients must be able to swallow intact fimepinostat capsules or mini-tabs without chewing or crushing
• Patients must have body surface area (BSA) >= 0.5 m^2
• Patients must undergo tumor tissue collection as part of their standard of care

• Minimum possible tissue collected must be equivalent to about 4-6 stereotactic core biopsies
• Prior Therapy: Patients in the medulloblastoma and HGG strata will be allowed to have undergone prior therapy including surgery, chemotherapy, and radiation therapy. Patients in the newly diagnosed DIPG stratum should not have received prior therapy before the initiation of fimepinostat, with the exception of those patients who received temozolomide during radiation therapy or who previously received radiation as per standard of care and have not yet undergone a biopsy. All patients who have received therapy other than radiation and temozolomide should be discussed with study chair(s) prior to enrollment. Patients must have fully recovered from acute side effects related to previous anti-cancer therapies. Patients undergoing radiation during protocol therapy will not be permitted to receive other concomitant agents with radiation and pending initiation of maintenance with fimepinostat
