Selumetinib for Plexiform Neurofibroma
(NF114 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether early treatment with selumetinib, a type of medication, can benefit young children with NF1 who have plexiform neurofibromas (PN) in challenging locations before they cause problems. Selumetinib has been shown to shrink these tumors in children, potentially alleviating symptoms like pain or movement issues. The study targets children with NF1 who either do not have any known PNs yet or have them in high-risk areas without symptoms. Participants should not have previously undergone an MRI for these tumors or received selumetinib treatment. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.
Do I need to stop my current medications to join the trial?
The trial requires stopping any herbal supplements or medications that affect certain liver enzymes at least 14 days before starting the study medication. If you are on blood pressure medication, you must be on a stable regimen for at least 30 days before joining. Other medications are not specifically mentioned, so it's best to discuss with the study team.
Is there any evidence suggesting that selumetinib is likely to be safe for humans?
Research has shown that selumetinib has been well-studied in children with neurofibromatosis type 1 (NF1) who have plexiform neurofibromas (PN) that cannot be surgically removed. In a previous study with 74 children, selumetinib was generally well-tolerated. Most children experienced lasting tumor shrinkage, meaning the tumors became smaller and remained so. Many also reported less pain after taking the drug.
Common side effects included nausea, vomiting, and diarrhea, but these were generally manageable. Another study demonstrated that with up to five years of treatment, children continued to do well with selumetinib, experiencing ongoing tumor shrinkage and pain relief. This long-term data suggests that selumetinib's safety remains consistent over time.
In summary, selumetinib has shown a reliable safety record in children with NF1-related PN, providing both tumor reduction and pain relief with manageable side effects.12345Why are researchers excited about this study treatment for plexiform neurofibroma?
Most treatments for plexiform neurofibromas, which often include surgery or watchful waiting, focus on managing symptoms rather than directly targeting the root cause. Selumetinib is unique because it specifically targets the MEK pathway, which plays a key role in the growth of these tumors. This targeted approach holds promise for actually slowing or stopping tumor growth, rather than just alleviating symptoms. Researchers are excited about Selumetinib because it offers a potential non-surgical option for managing these challenging tumors, particularly in young patients with high-risk tumors.
What is the effectiveness track record for selumetinib in treating plexiform neurofibroma?
Research has shown that selumetinib effectively treats plexiform neurofibromas (PN) in children with neurofibromatosis type 1 (NF1). In previous studies, most children experienced significant tumor shrinkage, which improved symptoms like pain and movement. The SPRINT study found that selumetinib was effective in 68% of cases, reducing tumor size for most participants. Even in adults, selumetinib decreased tumor size and relieved pain. In this trial, participants will be randomized to receive selumetinib or undergo observation to assess its effectiveness in preventing PN growth. These findings suggest that selumetinib could be a promising treatment for PN in both children and adults.35678
Are You a Good Fit for This Trial?
This trial is for children aged over 1 year but under 8 with Neurofibromatosis Type 1 (NF1) who have Plexiform Neurofibromas (PN) in high-risk areas but don't yet show symptoms. They must not have had previous MRIs of the PN area and should be generally healthy based on a recent physical exam.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Part 1: WBMRI for NF1 patients
To assess the incidence of asymptomatic PN in any location in participants with NF1 and no known PN
Part 2: Treatment randomization
Randomization to selumetinib vs observation to determine if selumetinib prevents PN growth in young participants with asymptomatic tumors
Part 3: Intermittent dosing schedule
To assess the proportion of participants who are able to maintain tumor response after transition to an intermittent dosing schedule
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Selumetinib
Trial Overview
The study tests if early treatment with Selumetinib can prevent growth or complications from asymptomatic PNs in NF1 patients. It's based on prior success where Selumetinib shrank PNs, improving pain and mobility in children.
