ClinConnect Summary

This clinical trial, called Guselkumab Immunogenetics, is looking at how well a treatment called guselkumab works for people with two types of psoriasis: guttate psoriasis and plaque psoriasis. The goal is to see how effective the treatment is and how it affects the immune system. The study is currently recruiting participants who are at least 18 years old and have a diagnosis of either guttate psoriasis (which has started within the last year) or chronic plaque psoriasis (which has lasted more than five years). Participants must have a certain level of skin involvement and be candidates for other treatments, such as phototherapy or systemic therapy.

If you join the trial, you will receive the guselkumab treatment and be closely monitored for your response. To be eligible, you should not have any serious infections, significant medical conditions, or a history of certain cancers. Women who can become pregnant need to use effective birth control during the study. This trial is a chance to help improve treatment options for psoriasis and contribute to important research.
