Adavosertib and Local Radiation Therapy in Treating Children With Newly Diagnosed Diffuse Intrinsic Pontine Gliomas
- for people ages 37 months to 21 years (full criteria)
- at UCSF
- study started
This phase I trial studies the side effects and the best dose of adavosertib when given together with local radiation therapy in treating children with newly diagnosed diffuse intrinsic pontine gliomas. Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. Giving adavosertib with local radiation therapy may work better than local radiation therapy alone in treating diffuse intrinsic pontine gliomas.
A Phase 1 Study of AZD1775 (MK-1775) Concurrent With Local Radiation Therapy for the Treatment of Newly Diagnosed Children With Diffuse Intrinsic Pontine Gliomas
- To estimate the maximum tolerated dose (MTD) or recommended phase 2 dose and schedule of the adavosertib (Wee1 inhibitor AZD1775 [MK-1775]) administered concurrently with radiation therapy in children with newly diagnosed diffuse intrinsic pontine glioma (DIPG).
II. To define and describe the toxicities of AZD1775 (MK-1775) given concurrently with radiation therapy in children with newly diagnosed DIPG.
III. To characterize the pharmacokinetics of AZD1775 (MK-1775) in children with newly diagnosed DIPG when given concurrently with radiation therapy.
- To preliminarily define the antitumor activity of AZD1775 (MK-1775) within the confines of a phase 1 study, including response rate, progression free survival, and overall survival of treated patients.
II. To assess the biologic activity of AZD1775 (MK-1775) by measuring expression of phosphorylated-cell division cycle 2 G1 to S and G2 to M (p-CDC2) (cyclin-dependent kinase 1 [CDK1]) and phosphorylated-histone H3 (p-HH3) in peripheral blood mononuclear cells (PBMCs) before and after administration of AZD1775 (MK-1775) in children with newly diagnosed DIPG.
III. To assess the biologic activity of AZD1775 (MK-1775) by measuring expression of gamma-H2A histone family, member X (H2AX) in PBMCs, a marker of deoxyribonucleic acid (DNA) double-strand breaks (dsDNA), before and after administration of AZD1775 (MK-1775) in children with newly diagnosed DIPG.
OUTLINE: This is a dose-escalation study of adavosertib.
Patients undergo radiation therapy 5 days a week for 6 weeks (up to 30 fractions). Patients also receive adavosertib orally (PO) on days 1-5 of weeks 1, 3, and 5; days 1-5 of weeks 1, 3, and 5 AND days 1, 3, and 5 of weeks 2, 4, and 6; OR days 1-5 of weeks 1-6 depending on dose level assignment. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, every 2 months for 6 months, and then every 3 months thereafter.
