Fimepinostat in Treating Brain Tumors in Children and Young Adults
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.
A Target Validation Study of Fimepinostat in Children and Young Adults With Newly Diagnosed Diffuse Intrinsic Pontine Glioma (DIPG), Recurrent Medulloblastoma, or Recurrent High-Grade Glioma (HGG)
- 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 in primary tumor tissue.
- 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.
- 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.
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.

- 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 (DIPG) (World Health Organization [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
- 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
- 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 m2
- 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
- Strata B & C: Patients in the medulloblastoma and HGG strata will be allowed to have undergone prior therapy including surgery, chemotherapy, and radiation therapy. Patients in the DIPG stratum are not allowed to have prior therapy before the initiation of fimepinostat. 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
- Myelosuppressive chemotherapy: At least 21 days after last dose of myelosuppressive chemotherapy (42 days if prior nitrosourea)
- Hematopoietic growth factors: At least 14 days after last dose of a long-acting growth factor or 7 days after short-acting growth factor or beyond time during which adverse events are known to occur
- Biologic (anti-neoplastic agent): At least 7 days after last dose of a biologic agent or beyond time during which adverse events are known to occur
- Monoclonal antibodies: At least 21 days after last dose of monoclonal antibody
- At least 2 weeks after local palliative radiotherapy (XRT)
- At least 3 months from craniospinal XRT, or XRT to > 50% pelvis
- At least 21 days from major surgery (biopsy and central line placement/removal are not considered major)
- Corticosteroids: Subjects who are receiving dexamethasone must be on a stable or decreasing dose for at least 7 days prior to enrollment
Peripheral absolute neutrophil count (ANC) >= 1000/mm3
Platelet count >= 100,000/mm3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
