Brief Summary
Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES:
- To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum.
- To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE:
- To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.

Outcome Measures
Primary Outcomes (4)
Estimate the Maximum tolerated dose (MTD)/Recommended Phase 2 Dose (RP2D) of each doublet by stratum
The MTD is empirically defined as the highest dose level at which six patients have been treated with at most one patient experiencing a dose-limiting toxicity (DLT) and the next higher dose level has been determined to be too toxic. The MTD estimate will not be available, if the lowest dose level studied is too toxic or the highest dose level studied is considered safe. In the latter case, the highest studied safe dose will be considered the recommended phase 2 dose (RP2D). The MTD estimation will be limited to evaluable patients and toxicity assessments from course 1 (28 days).

Study Arms (3)
A: ribociclib + gemcitabine
EXPERIMENTALStratum A participants with a diagnosis of refractory or recurrent medulloblastoma (Group 3/4) or refractory or recurrent ependymoma. (including: ependymoma, not otherwise specified (NOS), WHO Grade III; ependymoma, RELA fusion positive; anaplastic ependymoma; ependymoma, NOS, WHO grade II). They receive combination treatment with ribociclib and gemcitabine. They may also receive growth therapy support with filgrastim. Stratum A has completed all the necessary accrual
B: ribociclib + trametinib
EXPERIMENTALStratum B participants with a diagnosis of one of the following refractory or recurrent CNS diseases: medulloblastoma, \[sonic hedgehog (SHH)- or WNT-activated\];; high grade glioma (including: high grade glioma, (NOS), WHO Grade III or IV; anaplastic astrocytoma, IDH mutant; glioblastoma, IDH-wildtype; glioblastoma, IDH-mutant; diffuse midline glioma, H3K27-mutant; anaplastic oligodendroglioma, IDH mutant and 1p/19q-codeleted; anaplastic pleomorphic xanthoastrocytoma); select CNS embryonal tumors (including: embryonal tumors with multilayered rosettes, C19MC-altered; embryonal tumors with multilayered rosettes, NOS; medulloepithelioma; CNS neuroblastoma; CNS ganglioneuroblastoma; CNS embryonal tumor, NOS; atypical teratoid/rhabdoid tumor; CNS embryonal tumor with rhabdoid features). They receive combination treatment with ribociclib and trametinib. Stratum B has completed all the necessary accrual
C: ribociclib + sonidegib
EXPERIMENTALStratum C participants with refractory or recurrent medulloblastoma (SHH-activated) \>6 months off smoothened inhibitor, presence of 9q loss or PTCH1 mutant, skeletally mature. They received combination treatment with ribociclib and sonidegib. Stratum C is being closed due to low accrual

Eligibility Criteria
You may not qualify if:
- Participants with recurrent, progressive, or refractory brain tumors.
- Age ≥ 1 year and \< 25 years at the time of screening. Exception: Participants with recurrent, progressive, or refractory Medulloblastoma and are ≥ 1 and \< 40 years of age at the time of study screening are eligible for screening.
- Participants and/or guardian have the ability to understand and the willingness to sign a written informed consent document according to institutional guidelines.
- Participants with a diagnosis of recurrent, progressive, or refractory low grade glioma (LGG).
- Previous exposure to a CDK4/6 inhibitor (palbociclib, abemaciclib, or ribociclib).
- Participants with a history of clinically significant, uncontrolled heart disease and/or repolarization abnormalities.
- Participants with any history of QTc prolongation (i.e. QTc interval of \> 450 msec).
- Evaluable disease, as defined as meeting any of the following:
- Patients who have measurable disease
- Patients with radiologically discernible but non-measurable lesions (i.e. leptomeningeal disease)
- Patients with CSF positive disease
- Participants must have received their last dose of anticancer therapy (including experimental) at least 4 weeks prior to study enrollment.
- Note: Participants must have relapsed with recurrent, progressive or refractory disease on or after any prior anticancer therapy.
- Participants must have had their last fraction of radiation at least 4 weeks prior to study enrollment. Participants who received radiation therapy for palliation must have had their last fraction of radiation at least 2 weeks prior to study enrollment.
- Note: Participants must have relapsed with recurrent, progressive or refractory disease after any prior radiation therapy that is not considered palliative. Palliative radiation therapy is defined as local small port RT to alleviate and/or palliate symptoms. (CSI, whole brain RT, large field/port RT, or large field/port multilevel spinal RT will not be considered palliative at any dose.)
