FDA approves Sun Pharma Ilumya for adults with active psoriatic arthritis
The FDA has approved Sun Pharma's Ilumya for adults with active psoriatic arthritis, expanding the IL-23 inhibitor beyond its established plaque psoriasis indication.
Ilumya (tildrakizumab-asmn) received a supplemental biologics licence approval for active psoriatic arthritis following Phase III INSPIRE-1 and INSPIRE-2 studies that met their primary ACR20 response endpoints at week 24.
The new indication extends the medicine's use to inflammatory joint disease while retaining healthcare professional administration, providing another approved IL-23-targeted treatment option for eligible adults in the United States.
