In July 2023, the FDA granted mirdametinib rare pediatric disease designation for the treatment of Neurofibromatosis Type 1 (NF1), which provides eligibility for a priority review voucher upon FDA approval [1[1[1[1].
On February 11, 2025, the Food and Drug Governance approved mirdametinib (Gomekli, SpringWorks Therapeutics, Inc.), a kinase inhibitor, for adult and pediatric patients 2 years of age and older with NF1 who have symptomatic plexiform neurofibromas [2[2[2[2].
the approval followed a rolling submission of a new drug application (NDA) to the FDA for the investigational MEK inhibitor mirdametinib in pediatric and adult patients with NF1 [3[3[3[3].

In a groundbreaking move, the FDA has granted rare pediatric disease designation to mirdametinib for the treatment of Neurofibromatosis Type 1 (NF1). This designation provides eligibility for a priority review voucher upon FDA approval. On February 11, 2025, the FDA approved mirdametinib (gomekli, SpringWorks Therapeutics, Inc.), a kinase inhibitor, for both adult and pediatric patients aged 2 years and older with NF1 who have symptomatic plexiform neurofibromas.This approval followed a rolling submission of a new drug application (NDA) to the FDA for the investigational MEK inhibitor mirdametinib in pediatric and adult patients with NF1.
Background on Mirdametinib and Neurofibromatosis Type 1
Mirdametinib is a targeted therapy that inhibits the MAPK pathway, which is frequently enough dysregulated in NF1.Neurofibromatosis Type 1 is a genetic disorder that can cause noncancerous tumors to grow on nerves in the brain, spinal cord, and skin. These tumors, known as plexiform neurofibromas, can cause significant morbidity and can be life-threatening if they compress vital structures.
Expert Interview
Senior Editor, world-today-news.com: today, we have with us Dr. emily Hart, a renowned specialist in pediatric oncology and neurofibromatosis.Dr. Hart, can you provide some context on the meaning of the FDA’s recent approval of mirdametinib for NF1?
Dr. Emily Hart: Certainly. The FDA’s approval of mirdametinib represents a significant milestone in the treatment of Neurofibromatosis Type 1. For many years, there have been limited therapeutic options for patients with symptomatic plexiform neurofibromas. Mirdametinib’s approval provides a much-needed targeted therapy that addresses the underlying genetic abnormalities in NF1.
Senior Editor, world-today-news.com: Can you explain how mirdametinib works in the context of NF1?
Dr. Emily Hart: Mirdametinib is a MEK inhibitor that targets the MAPK pathway, which is frequently dysregulated in NF1. By inhibiting this pathway, mirdametinib can reduce the proliferation of abnormal cells and perhaps shrink plexiform neurofibromas. This mechanism is notably relevant in NF1 as the disease is frequently enough characterized by mutations in the NF1 gene that lead to overactivation of the MAPK pathway.
Senior Editor, world-today-news.com: The FDA granted mirdametinib rare pediatric disease designation.What dose this mean for the future of pediatric NF1 treatment?
Dr. Emily Hart: The rare pediatric disease designation is a significant step forward. It provides an incentive for further research and progress in pediatric NF1 treatment. This designation can accelerate the approval process and make it more attractive for pharmaceutical companies to invest in clinical trials for pediatric patients. Ultimately, it could lead to more effective and targeted treatments for children with NF1.
Senior Editor, world-today-news.com: What are the potential benefits and challenges of using mirdametinib in pediatric patients?
Dr. Emily Hart: The benefits are considerable. Mirdametinib offers a targeted approach that could improve quality of life and reduce morbidity in pediatric patients with NF1. Though, there are challenges as well. Pediatric patients may respond differently to the drug compared to adults, so careful monitoring and dose adjustments are essential. Additionally, long-term effects and potential side effects need to be closely studied to ensure the safety and efficacy of the treatment.
Senior Editor, world-today-news.com: How do you envision the future of NF1 treatment with the approval of mirdametinib?
Dr. Emily Hart: The approval of mirdametinib opens new avenues for NF1 treatment. It sets a precedent for targeted therapies in genetic disorders and could pave the way for further research into other targeted treatments.We may see more drugs being developed to specifically address the underlying genetic abnormalities in NF1, leading to better outcomes for patients.
Conclusion
The FDA’s approval of mirdametinib for the treatment of Neurofibromatosis Type 1 marks a significant advancement in pediatric oncology. dr. Emily Hart emphasizes the potential benefits of this targeted therapy in improving the lives of patients with NF1. As research continues, we can expect more innovative treatments to emerge, offering hope for those affected by this complex genetic disorder.
