Clinical study: Clinical studies are research studies that evaluate potential medicines by testing them in a group of people. They are the primary way researchers determine the safety and efficacy of potential treatment.

Efficacy: The ability of a medication to produce a desired, beneficial outcome. In a clinical study, the efficacy of a drug is evaluated in patients.

MRI: A magnetic resonance imaging scan (MRI) produces an image of the body using a strong magnet and radio waves. An MRI can help your child’s doctor identify plexiform neurofibromas and can also help them see if your child is responding to treatment.

Neurologist: A neurologist is a medical doctor who specializes in treating diseases of the nervous system. The nervous system is made of 2 parts: the brain, and the spinal column and nerves. Neurologists may treat NF1 PN (which is a noncancerous tumor of the nerves).
