Brief Summary:
This phase I trial studies the side effects and best dose of entinostat in treating pediatric patients with solid tumors that have come back or have not responded to treatment. Entinostat may block some of the enzymes needed for cell division and it may help to kill tumor cells.

PRIMARY OBJECTIVES:
I. To estimate the maximum tolerated dose (MTD) and/or recommended phase 2 dose of entinostat administered as a single-agent, once weekly to children with recurrent or refractory solid tumors.
II. To define and describe the toxicities of entinostat administered as a single agent, once weekly to children with recurrent or refractory solid tumors.
III. To characterize the pharmacokinetics of entinostat in children with recurrent or refractory cancer.
SECONDARY OBJECTIVES:
I. To preliminarily define the antitumor activity of entinostat within the confines of a phase 1 study.
II. To assess change in histone H3 and H4 acetylation in peripheral blood mononuclear cells (PBMCs) as a marker of the biologic activity of entinostat.
OUTLINE: This is a dose escalation study.
Patients receive entinostat orally (PO) on days 1, 8, 15, and 22. Cycles repeat every 28 days for up to 5 years in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures :
- Maximum Tolerated Dose (MTD) or Recommended Phase 2 Dose (R2PD) of Entinostat [ Time Frame: Up to 28 days ]The MTD/RP2D will be defined as the maximum dose at which fewer than one-third of patients experience dose limiting toxicity during cycle 1 of therapy among 6 toxicity-evaluable patients. The frequency of cycle 1 dose limiting toxicities will be summarized by dose level among patients in the dose escalation part of the study.
- Frequency of Adverse Events for Entinostat [ Time Frame: Up to 28 days ]The frequency of patients with at least one Grade 3 or greater adverse event that are at least possibly attributable to entinostat during cycle 1 will be summarized by study part, dose level.
- Half-life of Entinostat [ Time Frame: Plasma concentrations were measured at 0, 0.5, 1, 3, 6, 24, and 48-96 hours post-dose during cycle 1, day 1. ]The median (min, max) Half-Life of entinostat stratified by study part and dose level. The half-life (t1/2) was calculated using the equation t1/2 = 0.693/λz, where the terminal elimination rate constant (λz) was determined from a least-squares regression of the log-transformed plasma concentration vs. time data for the last 3 - 4 time points.
- Peak Plasma Concentration of Entinostat: C-Max [ Time Frame: Up to 96 hours ]The median (min, max) of the peak plasma concentration of entinostat stratified by study part, dose level. Time points were assessed at 0, 0.5, 1, 3, 6, 24, and 48-96 hours post-dose during cycle 1, day 1.
- Total Area Under the Plasma Concentration Curve of Entinostat: AUC [ Time Frame: Up to 96 hours ]The median (min, max) of the total area under the plasma concentration curve of entinostat stratified by study part, dose level. Time points were assessed at 0, 0.5, 1, 3, 6, 24, and 48-96 hours post-dose during cycle 1, day 1.
- Time to Reach Maximum Plasma Concentration of Entinostat: T-Max [ Time Frame: Up to 96 hours ]The median (min, max) of the time to reach maximum plasma concentration of entinostat stratified by study part, dose level. Time points were assessed at 0, 0.5, 1, 3, 6, 24, and 48-96 hours post-dose during cycle 1, day 1.
Secondary Outcome Measures :
- Antitumor Activity of Entinostat [ Time Frame: Up to 4 years 9 months ]Frequency of response to entinostat per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and/or assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR, stratified by study part and dose
- Change in Histone H3 Acetylation of Entinostat [ Time Frame: Up to 28 days ]Median (IQR) change in H3 acetylation in peripheral blood mononuclear cells (PBMCs) versus baseline stratified by study part, dose level.
- Change in Histone H4 Acetylation of Entinostat [ Time Frame: Up to 28 days ]Median (IQR) change in H4 acetylation in PBMCs versus baseline stratified by study part, dose level.
