Next-Generation Anti-IL-17 Agents for Psoriatic Disease: A Pipeline Review

Innovations in biologics are transforming the treatment of psoriatic diseases. The ability to target specific levels of immune activation provides a distinct advantage. Interleukin (IL)-17 inhibitors fall into this class of biologics, and they are effectively used to treat a spectrum of psoriatic diseases, such as psoriasis vulgaris and psoriatic arthritis. In recent years, anti-IL-17 agents have been the focus of therapeutic development, with various formulations and routes of administration. In this manuscript, we review pipeline anti-IL-17 therapies for psoriatic diseases identified through a search of ClinicalTrials.gov (January 2019–December 2024) and other databases. Key agents under investigation include netakimab, vunakizumab, xeligekimab, gumokimab, HB0017, CJM 112, JS005, 608, LZM012, ZL-1102, izokibep, sonelokimab, DC-806, DC-853, and LEO 153339. Both preclinical and clinical trial data for each agent are summarized, with an emphasis on their efficacy, adverse effects, immunogenicity, and future outlooks.
