Trametinib for juvenile myelomonocytic leukemia (JMML)

PROJECT 3: A High Content Clinical Trial of the MEK inhibitor Trametinib in JMML

NIH-funded research Indiana University Indianapolis · NIH-11181022

This gives the drug trametinib to children with JMML to try to block overactive MEK signaling and control their leukemia.

What this research studies

Children with neurofibromatosis type 1 (NF1) and other Ras-pathway mutations can develop JMML, an aggressive childhood leukemia with high relapse after stem cell transplant. This project treats pediatric JMML patients with the MEK inhibitor trametinib to target the overactive Ras/Raf/MEK/ERK pathway that drives the disease. The team used genetically engineered mouse models that responded well to MEK inhibitors and opened a national phase to offer trametinib to affected children. Participants will be seen at specialized pediatric cancer centers for treatment, monitoring, and genetic testing as part of the protocol.

Who could benefit from this research

Good fit: Children (typically infants and young children up to about 11 years) diagnosed with JMML, especially those with NF1 or other Ras-pathway mutations and those with residual or relapsed disease, are the intended candidates.

Not a fit: Children whose leukemia is driven by unrelated genetic pathways or who cannot tolerate MEK inhibitors are less likely to benefit from this approach.

Why it matters

Potential benefit: If successful, trametinib could reduce disease activity, lower post-transplant relapse, and offer a targeted therapy option for children with JMML.

How similar studies have performed: Preclinical mouse models showed strong activity of MEK inhibitors, and MEK inhibitors have shown benefit in other RAS-driven conditions, but targeted therapy in JMML remains relatively new.
