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 2 strata:
- Stratum A for recurrent/ progressive tumors
- Stratum B for recently diagnosed patients who have completed standard radiation therapy without progressive disease
- Stratum A: 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 B: 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.
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).
Research participants with high-grade glioma or diffuse intrinsic pontine glioma will receive crizotinib and dasatinib.

However, interval must be > or = 1 week from last dose of oral etoposide and other drugs administered at low doses (metronomic regimen) before study enrollment

Inclusion Criteria: Stratum B
- Completion of local RT with or without concomitant chemotherapy including temozolomide and radiosensitizing agents (e.g., carboplatin, vorinostat) outside the context of a clinical trial. Any agent administered during RT should have a short half-life so that it should already be completely eliminated by the start of this therapy. If other agents were used concurrently with RT, they will need to be discussed with the principal investigator to assess eligibility

About this clinical trial
Diffuse intrinsic pontine glioma (DIPG) and high-grade gliomas are fast-growing, cancerous brain tumors. High-grade gliomas are cancerous tumors that grow in the brain or spine. DIPG is a high-grade glioma that forms at the point where the brain meets the spinal cord, which is called the brainstem.
These tumors are hard to treat because surgery to remove them is often not an option, and standard radiation therapy does not usually work well. In other types of cancers, radiation therapy and chemotherapy work well because they destroy tumors by causing breaks in their DNA (genetic materials inside the tumor cells). In gliomas, it appears that the tumor is able to repair DNA damage caused by radiation therapy and chemotherapy.
Most children and young adults with DIPG and high-grade gliomas cannot be cured with current treatments. At St. Jude, researchers are determined to find new treatments for patients with DIPG and high-grade gliomas.
Purpose of this clinical trial
In this Phase I clinical trial, St. Jude researchers want to find out if a combination of two oral chemotherapy drugs, crizotinib and dasatinib, is safe for participants with DIPG and high-grade gliomas after they have received radiation therapy.
Crizotinib is approved for the treatment of lung cancer, and dasatinib is approved for the treatment of leukemia in adults. Neither drug is approved for treating children or adults with brain and spinal cord tumors, so the use of these drugs in this trial is investigational. Both medications are thought to block specific proteins in the body that cause cancer to grow and spread.
Two groups of participants with DIPG and high-grade gliomas will take part in this study:
- Group 1: participants whose tumors have grown after previous treatment
- Group 2: participants with newly diagnosed DIPG or high-grade glioma whose tumors have not grown after initial treatment, including radiation therapy
All participants will receive treatment with crizotinib and dasatinib once daily. Crizotinib is made as a liquid or capsule. Dasatinib is available as tablets. Participation in this trial may last up to two years, as long as the tumor is responding to the treatment and the participant is able to tolerate its side effects.
- Between 2 and 21 years of age
