• A recent study published in JACC: Basic to Translational Science indicates that trametinib reduces mortality and morbidity in children with severe hypertrophic cardiomyopathy (HCM).
• The study focused on children with HCM caused by pathogenic variants in the RAS/MAPK pathway, highlighting the potential for personalized treatment approaches.
• Results showed a significant reduction in death, cardiac transplantation, or the need for cardiac surgery in children treated with trametinib compared to standard care.
• While dermatologic and mucous membrane side effects were common, no life-threatening adverse events were observed, suggesting manageable safety profiles.
