The purpose of this study is to evaluate the investigational oral drug AMXT 1501 in combination with oral eflornithine (DFMO). An investigational drug is one that has not been approved by the U.S. Food \& Drug Administration (FDA), or any other regulatory authorities around the world for use alone or in combination with any drug, for the condition or illness it is being used to treat.
The goals of this part of the study are:
* Establish a recommended dose of AMXT 1501 in combination with DFMO * Test the safety and tolerability of AMXT 1501 in combination with DFMO * To determine the activity of study treatments chosen based on: * How each subject responds to the study treatment * How long a subject lives without their disease returning/progressing
Safety Run-in (Dose level 1)-The first three (3) participants enrolled will be ≥ 12 years of age at enrollment. Once evaluated for safety by DSMB, we will move on to the next three (3) participants enrolled who will be ≥6 years of age at enrollment. Once evaluated for safety by DSMB, we will move on to the Phase I.
Phase I and II: ≤ 26 years of age at diagnosis.
