Introduction to Skyrizi

Overview of Skyrizi
Skyrizi (risankizumab) is a highly selective interleukin-23 (IL-23) inhibitor that has emerged as a transformative therapeutic option in the immunology space. Developed by AbbVie in collaboration with Boehringer Ingelheim, Skyrizi targets the p19 subunit of IL-23 and thereby interrupts the inflammatory cascade that underpins multiple autoimmune conditions. Since its initial approval for moderate-to-severe plaque psoriasis in 2019, the drug has been advanced to treat other indications such as psoriatic arthritis and Crohn’s disease. The molecule’s unique mechanism, high selectivity, and robust clinical performance in head-to-head trials position it favorably against older therapies. Its ability to deliver not only symptomatic relief but also meaningful improvements in clinical and endoscopic markers has captured the attention of both clinicians and investors. By leveraging the increasing understanding of the IL-23 pathway’s role in chronic inflammatory diseases, Skyrizi is now viewed as a next-generation biologic with the potential to address a range of immunologic disorders.
