Sun Pharma's ILUMYA sBLA for Psoriatic Arthritis Accepted by US FDA
Sun Pharma's supplemental Biologics License Application (sBLA) for ILUMYA® for active psoriatic arthritis has been accepted for review by the US FDA. The FDA decision is expected by October 29, 2026. This application is based on positive Phase 3 study results.
The acceptance of the sBLA is a significant step towards a potential new indication for ILUMYA, which could expand its market reach and revenue streams. However, the actual impact depends on the final FDA approval and market adoption.
The US FDA's acceptance of the sBLA for ILUMYA for psoriatic arthritis is a positive development, indicating potential for a new indication and expanded market access for the drug.
Sun Pharmaceutical Industries Limited announced that the US Food and Drug Administration (FDA) has accepted for review the supplemental Biologics License Application (sBLA) for ILUMYA® (tildrakizumab-asmn) for the treatment of adults with active psoriatic arthritis. The FDA's regulatory action date for this sBLA is anticipated by October 29, 2026.
If approved, this would represent a new indication for ILUMYA, expanding its use beyond the treatment of moderate-to-severe plaque psoriasis, for which it received US FDA approval in 2018. The sBLA is supported by positive results from the INSPIRE-1 and INSPIRE-2 Phase 3 clinical studies, which evaluated the efficacy and safety of ILUMYA in adult patients with active psoriatic arthritis. Top-line findings from these studies were reported in July 2025.
Sun Pharma aims for ILUMYA to become a differentiated first-choice advanced systemic treatment for active psoriatic arthritis, building on its established clinical experience as an IL-23 inhibitor. The drug has demonstrated durable skin clearance and a well-characterized safety profile, with nearly 140,000 patients supported worldwide since its approval. ILUMYA has also received marketing authorization from over 55 health authorities globally.
