Prurigo Nodularis Clinical Trials


Prurigo nodularis (PN) is a skin disease that presents as hard, itchy bumps known as nodules. The itching can be severe, and many patients scratch to the point of causing pain, bleeding, and permanent scarring. Unfortunately, scratching prurigo nodularis can lead to even more lesions. Itching is often exacerbated by sweat, heat, or clothing. Nobody is certain of what causes PN, but the itching and appearance can interrupt sleep, daily activities, and relationships.

The nodules can be up to half an inch large and often have a dry, rough top. Some patients have just a few modules while others have hundreds. You’ll most often find PN on the shoulders, outer arms, and legs, although they can also appear just about anywhere else on the body and face. Nodules can be a variety of colors. Most PN sufferers are between 20 – 60 years old.
