Why is this Medical Research Study Important?

Prurigo Nodularis is defined by the presence of distinctive bumps (nodules) on the skin which can be very itchy and cause the intense desire to scratch. This itching is highly bothersome and is associated with sleep problems, depression, and the lack of ability to do things that are enjoyed. Currently, there is no approved treatment specifically for itching associated with Prurigo Nodularis. Therefore, finding new treatment options for people with this condition is extremely important.

Before new medications can be approved for public use, they must be tested in research studies like this one. This study will look at the safety and effectiveness of the study medication on the treatment of itching related to Prurigo Nodularis and will also evaluate the effect of the study medication on itch-related quality of life and sleep quality.
