JMML is a cancer of the blood. In JMML, the bone marrow makes large numbers of abnormal white blood cells. These abnormal blood cells crowd out the healthy, normal cells that belong in the bone marrow. These abnormal white cells can flood the blood and invade vital organs, including the spleen, lung, GI tract, and skin. Studies have found changes in the genes of people with JMML. Trametinib is a drug that works to target some of these changes found in JMML cells.
Objective:
To find out what effects trametinib has on people with JMML.
Eligibility:
People ages 2-21 with JMML that has come back after or did not respond to chemotherapy.
Design:
Participants will be screened with their medical history.
Participants will take the study drug in 28-day cycles. They will take the drug by mouth.
Participants will keep a diary of when they take the study drug each day.
Participants will have tests after Cycles 1, 2, 4, and every second cycle after. Some tests may be repeated during cycles. Tests may include:
Physical exam
Blood tests
Skin exam. Photos or biopsies may be taken of participants lesions.
Eye exams
Tests to monitor heart function
Cheek swabs
Optional bone marrow sample
CT or MRI scans
Participants will have up to 12 treatment cycles. They will stop treatment if they get bad side effects or their JMML gets worse. They will have follow-up exams and tests after they finish treatment.
Researchers will reach out to participants every year for 5 years after treatment to find out about their health.
