Sun Pharmaceutical Industries Limited announced that the U.S. FDA approved ILUMYA® (tildrakizumab-asmn) for adult patients with active psoriatic arthritis, extending its previous approval for moderate-to-severe plaque psoriasis.

ILUMYA, an interleukin-23 (IL-23) inhibitor administered exclusively by healthcare providers, now provides a treatment option for adults suffering psoriatic arthritis who may benefit from in-office administration or are unable to self-administer therapy.

The approval was granted following positive outcomes from Phase 3 INSPIRE-1 and INSPIRE-2 randomized, double-blind, placebo-controlled clinical trials assessing efficacy and safety after two doses at 24 weeks in adult patients with active psoriatic arthritis.

Safety data from these studies aligned with ILUMYA’s established safety profile, noting risks such as increased infections, including upper respiratory infections and COVID-19, and the necessity to evaluate patients for tuberculosis before starting therapy.

Psoriatic arthritis affects about 2.4 million Americans and can cause joint pain, swelling, and stiffness, with potential for permanent joint damage, often occurring in people with psoriasis.

ILUMYA is also approved for moderate-to-severe plaque psoriasis in multiple countries and carries the National Psoriasis Foundation Seal of Recognition for meeting established review criteria.

  • FDA approved ILUMYA (tildrakizumab-asmn) for treating active psoriatic arthritis in adults in the United States.
  • Expanded indication beyond moderate-to-severe plaque psoriasis, previously approved in 2018.
  • Approval supported by Phase 3 INSPIRE-1 and INSPIRE-2 studies demonstrating efficacy and safety after two doses at 24 weeks.
