Secukinumab for the Inflammatory Phase of Pyoderma Gangrenosum

The purpose of this research study is to find out what effects (good and bad) secukinumab has on the subject and their pyoderma gangrenosum. Secukinumab is a type of medicine called human monoclonal antibodies. Monoclonal antibodies are proteins that recognize and attach to other specific proteins (in this case, immune system hormones called "cytokines") that your body produces. The cytokine (a "messenger" protein in the body) that secukinumab binds to and reduces the activity of is a naturally occurring cytokine called interleukin-17A (IL-17A). IL-17A is believed to be partly responsible for inflammation (pain, swelling, redness), and researchers believe that IL-17A may cause symptoms PG.
