Introduction
ILUMYA (tildrakizumab), a monoclonal antibody developed by Sun Pharmaceutical Industries Ltd., targets the interleukin-23 (IL-23) pathway. Approved for moderate to severe plaque psoriasis in multiple markets, ILUMYA represents a significant advancement in biologic therapies addressing autoimmune dermatological conditions. This analysis synthesizes recent clinical trial data, evaluates current market dynamics, and projects future growth based on emerging trends.
Clinical Trials Update
Regulatory Approval and Clinical Development Milestones
Since its initial approval by the U.S. Food and Drug Administration (FDA) in 2018, ILUMYA has undergone extensive evaluation across multiple clinical stages. The pivotal trials, reSURFACE 1 and 2, demonstrated the drug's efficacy and safety profile in comparison to placebo and other biologics.
Recent Clinical Data
