About this study

Guselkumab is made in the laboratory and is a fully human monoclonal antibody. An antibody is something that targets and kills foreign objects in the body – in this case, small proteins that are released by cells and affect the behaviour of other cells.

This antibody, guselkumab, recognizes and blocks a specific small protein, IL-23, which is important in immune and inflammatory processes.

Enrolment for this study is closed.
