ILUMYA® Proves Effective in Treating Moderate-to-Severe Nail Psoriasis: Insights from AAD 2025 Conference

ILUMYA®: A Breakthrough in Treating Nail Psoriasis

A pivotal study presented at the AAD 2025 Conference by Sun Pharmaceutical Industries, Inc. revealed exciting findings regarding ILUMYA® (tildrakizumab-asmn) in the treatment of moderate-to-severe nail psoriasis. As inflammation and discomfort from nail psoriasis can significantly affect patients' well-being, this new data provides hope for many affected individuals.

Study Overview

In this Phase 3b, randomized, double-blind, placebo-controlled trial, 99 participants with moderate-to-severe plaque psoriasis were observed to evaluate the efficacy and safety of ILUMYA. The results were staggering, showing that patients using ILUMYA had more than a fivefold improvement in nail psoriasis severity when compared to those receiving a placebo. Specifically, 25.5% of patients undergoing ILUMYA treatment achieved a 75% improvement on the Nail Psoriasis Severity Index (mNAPSI 75) at the 28-week mark, compared to just 4.5% in the placebo group (P=0.003).

Furthermore, an impressive 29.4% of those treated reported either normal nails or only minimal visible psoriasis symptoms, as measured by the ViSENPsO® score, versus 4.2% in the placebo cohort (P=0.0008). This clinical tool is crucial for tracking patient progress and assessing treatment results effectively.

Safety and Tolerability

Safety is a primary concern with any treatment, and the ILUMYA study results were reassuring. The safety profile aligned with previous knowledge of ILUMYA, with no new serious adverse events reported. Common adverse reactions, occurring more frequently than in the placebo group, included upper respiratory infections, injection-site reactions, and diarrhea, but these events were manageable and consistent with existing patient data.

Expert Insights

Dr. Paul Yamauchi, the lead investigator, emphasized the significance of these results. He noted that nail psoriasis has long been a poorly managed subset of psoriasis, where other therapies often fail to provide timely relief.

“Many existing treatments do not yield satisfactory results for these patients, making this breakthrough especially meaningful,” Dr. Yamauchi commented. The persistent struggle of approximately 50% of plaque psoriasis patients who experience nail involvement has long affected their quality of life, both physically and psychologically. Dr. Marek Honczarenko, the Senior Vice President at Sun Pharma, echoed the sentiment, stating, “The success of ILUMYA during the trial offers hope not only for symptom relief but also for an overall better quality of life.”

ILUMYA® in Perspective

ILUMYA is known as a monoclonal antibody that specifically targets the p19 subunit of interleukin-23, inhibiting its role in promoting inflammation. It is already approved for use in adults with moderate-to-severe plaque psoriasis in the United States, Australia, Japan, and Europe under the brand name ILUMETRI®. The promising results of this study further reinforce the medication’s potential as a cornerstone treatment option for managing not only scalp psoriasis but also nail psoriasis.

While the results are encouraging, it is essential to take into account the treatment guidelines and potential contraindications. For instance, before initiating treatment with ILUMYA, a thorough evaluation for tuberculosis and consideration of patients with chronic infections is advised.

Conclusion

The findings from the AAD 2025 Conference present an exciting avenue for treating nail psoriasis patients, shedding light on an area that has seen limited therapeutic advancements in the past. This data adds to the growing repository of evidence portraying ILUMYA's efficacy, positioning it as a promising option for those struggling with nail psoriasis, ultimately aiming for improved patient outcomes in daily living.
