Lower-risk patients are defined as having a mutational burden of one clonal alteration AND a low DNA methylation classification.

High-risk patients are defined as having as having a mutational burden of more than one clonal alteration AND/OR an intermediate or high DNA methylation classification.

This clinical trial will test the safety and efficacy of combining trametinib and azacitidine in patients with juvenile myelomonocytic leukemia (JMML). Newly diagnosed lower-risk JMML patients will receive trametinib and azacitidine. High-risk JMML patients will receive trametinib, azacitidine, fludarabine, and cytarabine.

Primary Objectives:

1. To determine the safety of combining trametinib with azacitidine for patients with newly diagnosed lower-risk JMML.
2. To determine the safety of combining trametinib with azacitidine (Aza), fludarabine (FLA) and cytarabine for patients with newly diagnosed high-risk JMML.

Dosing:

Patients with newly diagnosed lower-risk JMML will be treated with daily azacitidine for 5 days in combination with daily trametinib for 28 days per course for up to 12 courses. Patients with newly diagnosed high-risk JMML will be treated with daily azacitidine, fludarabine, and cytarabine for 5 days in combination with daily trametinib for 28 days per course for up to 2 courses.

Patients will be concurrently enrolled into both the lower-risk and high-risk arm starting at Dose Level 1. The rolling 6 design will be used during Phase 1 of the study to confirm the recommended Phase 2 dose, separately for the lower-risk and high-risk arm, with one possible de-escalation.

Risk Stratified Treatment for Patients With Newly Diagnosed Juvenile Myelomonocytic Leukemia: A Phase I/II Non-randomized Study of Trametinib and Azacitidine With or Without Chemotherapy (IND #164058)

The incidence of dose limiting toxicities (DLTs) after the 1st course of therapy will be measured at different dose levels.
