Dasatinib and Everolimus in Treating Children with Newly Diagnosed, Recurrent, or Progressive High-Grade Glioma with PDGFR Alterations

Trial Status: Active

This phase II trial studies how well dasatinib and everolimus work in treating children with high-grade glioma with PDGFR alterations that is newly diagnosed, has come back, or is growing, spreading or getting worse. Dasatinib and everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

  • Absolute neutrophil count (ANC) > 750

  • No increase in steroid dose within the past 7 days
  • STRATUM A: Histological confirmation of a newly diagnosed high-grade glioma or DIPG
  • STRATUM B: Histological confirmation (at diagnosis or relapse) of a recurrent or progressive grade II-IV glioma (including DIPG)
  • Primary brain or spine tumor are eligible, including tumors with metastases, multiple lesions
  • Prior therapies * Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy * Myelosuppressive chemotherapy: Must not have received within 3 weeks (6 weeks if prior nitrosourea) * Hematopoietic growth factors: At least 7 days since the completion of therapy with a growth factor, 14 days for long- acting (e.g. PEG-filgrastim) * Biologic (anti-neoplastic agent): At least 7 days or 3 half-lives (whichever is longer) since the completion of therapy with a biologic agent * Radiation therapy: ** Strata A: >= 2 weeks and =< to 12 weeks must have elapsed from radiation ** Strata B: >= 2 weeks must have elapsed from focal radiation * Surgery: > 3 weeks from major surgery; if recent craniotomy, adequate wound healing must be determined by neurosurgical team * Autologous stem cell transplant or rescue: No evidence of active graft versus (vs.) host disease and >= 4 weeks must have elapsed
  • All patients and/or a legal guardian must sign institutionally approved written informed consent and assent documents
  • Participants must have a genomic (DNA and/or ribonucleic acid [RNA] alteration (mutation, fusion, and/or amplification) involving PDGF-A, PDGF-B, PDGFR-A, PDGFR-B, as identified by tumor (formalin-fixed, paraffin-embedded [FFPE] or fresh, diagnosis or relapse tissue, but relapse tissue preferred) sequencing; sequencing will be performed through the University of Michigan MI-ONCOSEQ study (Clinical Laboratory Improvement Act [CLIA]-certified), or other (non-university [U] of Michigan) CLIA-certified tumor DNA or RNA sequencing; for Michigan Oncology Sequencing Center (MI-ONCOSEQ), at least 1 mm cubed of tumor tissue or > 1 core biopsy of tumor tissue is required, fresh or formalin-fixed paraffin-embedded (FFPE)

I. To determine the 1 year and 2 year progression-free and overall survival rates in patients receiving dasatinib in combination with everolimus as an adjuvant therapy following surgery and radiation therapy for children with newly diagnosed high-grade glioma or diffuse intrinsic pontine glioma (DIPG) harboring PDGFR alterations. (Stratum A)

II. To determine the overall response rate after 2 cycles of dasatinib in combination with everolimus in children with refractory or recurrent glioma (grade II-IV, including DIPG) with PDGFR alterations. (Stratum B)


I. To define and describe the toxicities of dasatinib and everolimus administered as dual therapy.

II. To prospectively evaluate high b-value diffusion weighted imaging (DWI) as an imaging biomarker for dasatinib and everolimus activity.

III. To prospectively evaluate cerebrospinal fluid (CSF) and plasma cell-free tumor deoxyribonucleic acid (DNA) (ct-DNA) as a marker of disease activity in refractory glioma with PDGFR alterations.

IV. To prospectively evaluate CSF dasatinib level as (1) a marker of blood-CSF permeability of dasatinib and (2) a predictor of treatment response.


Patients receive dasatinib orally (PO) once daily (QD) or twice daily (BID), and everolimus PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 6 months, 1 year, and 2 years
