This study focuses on two conditions: Axial Spondyloarthritis (a type of arthritis mainly affecting the spine and sacroiliac joints) and Psoriatic Arthritis (a form of arthritis that affects some people who have psoriasis). The study will investigate a medication called ixekizumab, which is given as an injection under the skin.
The purpose of this research is to examine how ixekizumab affects inflammation throughout the entire body, including joints and areas where tendons and ligaments attach to bones. The medication will be administered as a solution for injection, with participants receiving up to 160 mg per day. The study will use special imaging techniques including MRI (magnetic resonance imaging) and CT (computed tomography) scans to monitor the effects of treatment.
The study will last for two years, during which participants will receive regular medical evaluations and imaging scans. The research will help understand how effectively the medication reduces inflammation in different parts of the body in people with these conditions. Throughout the study, doctors will monitor how the treatment affects both the spine and other joints in the body.
