What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a medication called NAC in children aged 8-16 with a condition called NF1. These children often have problems with movement and behavior, and there is no current treatment for these issues. NAC works by reducing harmful molecules in the brain, which may help improve these symptoms.

Will I have to stop taking my current medications?

If you are taking stimulant or psychotropic medications, you need to stay on a stable dose for at least 30 days before joining the study and keep that dose during the study. If you are using antidepressants, dopamine blocking agents, or mood stabilizers, you cannot participate in the trial.

Is N-Acetyl cysteine (NAC) safe for use in humans?

N-Acetyl cysteine (NAC) has been studied for its ability to reduce oxidative damage and side effects of chemotherapy in pediatric cancer models, suggesting it is generally safe for use in humans.12345

How does the drug N-Acetyl cysteine (NAC) differ from other treatments for Neurofibromatosis Type 1?

N-Acetyl cysteine (NAC) is unique because it is an antioxidant that aims to reduce oxidative stress, which is a different approach compared to other treatments that may not target oxidative stress directly. This drug is also used in other conditions to protect cells from damage, which highlights its potential to address underlying cellular issues in Neurofibromatosis Type 1.36789

What evidence supports the effectiveness of the drug N-Acetyl cysteine (NAC) for treating Neurofibromatosis Type 1?

Research suggests that oxidative stress plays a role in the development of tumors in Neurofibromatosis Type 1 (NF1), and NAC is known to help reduce oxidative stress. Although not directly tested for NF1, NAC's ability to balance oxidative stress may offer potential benefits for managing NF1-related conditions.1241011

Are You a Good Fit for This Trial?

This trial is for children aged 8-16 with neurofibromatosis type 1 (NF1) and an IQ of 70 or above. They must have a specific abnormal score on a motor skills test and be on stable doses of any psychotropic medication. It excludes those without NF1, under chemotherapy, with epilepsy, certain medical devices, using specific drugs like MEKINIST within the last month, or with severe psychiatric disorders.

What Are the Treatments Tested in This Trial?

Interventions

  • N-Acetyl cysteine
  • Placebo
Trial Overview The study tests N-acetylcysteine (NAC), an antioxidant therapy against a placebo in children with NF1 to see if it improves cognitive and motor functions. This Phase II trial is double-blind and controlled; participants won't know which treatment they're getting to ensure unbiased results.
