Using MEK inhibitors to treat hypertrophic cardiomyopathy in children with RASopathies

MEK Inhibitors for the Treatment of Hypertrophic Cardiomyopathy in Patients With RASopathies (MEKinRAS) - Randomized Controlled Trial

Phase 2 Interventional Medical University of Warsaw · NCT06555237

This study is testing if a new medication called trametinib can help children with RASopathies and hypertrophic cardiomyopathy feel better compared to standard treatment alone.

What this trial studies

This study aims to evaluate the effectiveness of trametinib, a MEK kinase inhibitor, in treating hypertrophic cardiomyopathy (HCM) in children with genetic mutations in the RAS/MAPK pathway, such as those seen in Noonan syndrome. It is a randomized, open-label trial involving patients aged 0 to 18 who have been diagnosed with both RASopathy and HCM. Participants will be divided into two groups: one receiving trametinib alongside standard treatment and the other receiving only standard treatment. The study will assess the effectiveness of trametinib over a three-month period, with potential continuation based on results.

Who should consider this trial

Good fit: Ideal candidates are children aged 0 to 18 with a confirmed genetic mutation in the RAS/MAPK pathway and a diagnosis of hypertrophic cardiomyopathy.

Not a fit: Patients who have contraindications to the medications involved or do not have a confirmed diagnosis of RASopathy or hypertrophic cardiomyopathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve heart function and quality of life for children with hypertrophic cardiomyopathy associated with RASopathies.

How similar studies have performed: While there have been isolated cases of success in treating HCM in patients with RASopathies, this approach is being tested in a well-designed randomized study for the first time.
