About this trial
Plexiform neurofibromas (PN) are known to cause significant morbidity in children with NF1. The recent FDA approval for selumetinib in children 2 years and older with inoperable symptomatic PN was based on the finding that selumetinib shrinks the majority of PN in children with NF1 and results in clinically meaningful benefit such as improvement in pain or range of motion. However, many morbidities, such as blindness or nerve damage, cannot be fully reversed with PN shrinkage. Therefore, there remains a critical need in this patient population to determine if young participants with PN in high-risk locations may benefit from early medical intervention prior to the development of clinical problems. This study will determine whether participants with asymptomatic PN in high-risk locations can potentially benefit from early treatment with selumetinib.
Eligibility criteria
Qualifiers
Age: > 1 (>12 months) and ≤8 years of age at the time of study enrollment.
Diagnosis: Participants with a diagnosis of NF1 based on the 2021 revised consensus criteria [52] and
No known PN (prior to enrollment on Part 1). Participants for whom there is clinical suspicion for a PN (e.g., subtle facial asymmetry or large overlying hyperpigmented area) may be included in the study after discussion with the Study Chair so long as they have not previously had an MRI of the region of concern and are otherwise asymptomatic.
Physical exam at your institution within 1 year prior to consent.
Disqualifiers
Presence of a known, symptomatic PN with or without previous MRI imaging.
Patients who have had previous whole-body MRI (WBMRI) are excluded from the study. However, patients who have had regional MRI(s) for an indication other than a PN and did not have a PN identified on previous MRI may still be eligible for the study.
Inability to undergo MRI and/or contraindication for MRI examinations following the MRI protocol.
Prior treatment with selumetinib or another specific MEK1/2 inhibitor.
