An International Observational Study of 3 Year Health Outcomes in the Biological Treatment of Moderate to Severe Plaque Psoriasis

A Study For Patients with Moderate-to-Severe Plaque Psoriasis

PSoHO is a study of adults who have been diagnosed with moderate to severe plaque psoriasis for at least 6 months. Approximately 3,000 patients who have decided to start or switch to a new biologic treatment will join this study. Patients will be enrolled from over 23 countries around the world.

The main purpose of the study is to compare how effective different biologic therapies are at treating plaque psoriasis over time. The study is also trying to get a better understanding of how plaque psoriasis affects overall health and the quality of day-to-day living.
