Spots Global Cancer Trial Database for Study of the Combination of Crizotinib and Dasatinib in Pediatric Research Participants With Diffuse Pontine Glioma (DIPG) and High-Grade Glioma (HGG)

Study Description

Brief Summary: This is a phase I study to find the highest tolerable dose of crizotinib and dasatinib given in combination to patients with diffuse intrinsic pontine glioma (DIPG) and other types of high grade gliomas (HGG). Participants will receive escalating doses until the highest dose is determined. Participants will be enrolled in two strata: stratum A for recurrent/ progressive tumors and stratum B for recently diagnosed patients who have completed standard radiation therapy without progressive disease. Up to 7 dosage levels will be tested. Both drugs are taken orally daily, once per day. Correlative pharmacokinetic and biology studies are planned, as well as advanced methods of magnetic resonance imaging (MRI).

Detailed Description: The Rolling 6 design will be used to estimate the maximum tolerated dose (MTD) and determine the dose-limiting toxicity (DLT) of the combination of escalating doses of crizotinib and dasatinib. Our goal is to accrue research participants for both stratum A and B. However, it is our expectation that the accrual of research participants to stratum B will proceed at a slower pace. Therefore, initially the strategy of dose escalation will be exclusively based on research participants treated at stratum A until the MTD of this combination is reached. Until the MTD of this combination is reached for research participants in stratum A, accrual of research participants in stratum B will be allowed at the highest dosage level which has already been deemed to be safe (i.e., no DLTs in three research participants or ≤ 1 DLT in six research participants). No research participants will be accrued to stratum B until at least one dosage level has been confirmed to be safe in stratum A. Once the MTD for stratum A is reached, we will accrue research participants at this same dosage level to stratum B following the rules of the Rolling 6 design. If the MTD for stratum A is well tolerated among research participants in stratum B, we will proceed with dose escalation for research participants in stratum B based on the same rules of the Rolling 6 design. This strategy is based on the premise that research participants who are more heavily pre-treated (stratum A) may not tolerate therapy as well as those with minimal previous treatment (stratum B). Primary Objectives: * To estimate the MTD of the combination of crizotinib (c-Met and ALK inhibitor) and dasatinib (bcr-abl, PDGFRA and B, src, lck, yes, and c-kit inhibitor) in pediatric research participants with recurrent or progressive DIPG and other HGGs (stratum A). * To estimate the MTD of the combination of crizotinib and dasatinib in research participants with DIPG or HGG who completed RT within a short interval prior to enrollment but have not experienced disease progression (stratum B).
