Tildrakizumab Shows Durable Response in Scalp Psoriasis

TOPLINE:

Tildrakizumab was well tolerated and achieved sustained response in patients with moderate to severe plaque psoriasis of the scalp in a phase 3 study.

METHODOLOGY:

• A 72-week, multicenter, randomized, double-blind, placebo-controlled phase 3b trial enrolled 231 patients with moderate to severe plaque psoriasis of the scalp.
• Patients were randomly assigned to receive placebo (n = 114) or tildrakizumab (n = 117) until week 16, when patients in the placebo group switched to receive tildrakizumab.
• The primary endpoint, Investigator Global Assessment modified 2011 (IGA) scalp response, was defined as a score of 0 (clear) or 1 (almost clear) or an improvement of at least two points at week 16.
• The treatment was stopped at week 52, and participants were observed for another 20 weeks for safety and tolerability.

TAKEAWAY:

• At week 16, the response rate was higher in the tildrakizumab group than in the placebo group (49.4% vs 7.3%; P
• Psoriasis Scalp Severity Index 90 (PSSI 90) response rates were 60.7% and 4.9% at week 16 in the tildrakizumab and placebo groups, rising to 65.2% and 57.3%, respectively, at week 52.
• More than 80% of the week 16 responders maintained IGA and PSSI 90 responses at week 52.
• More than 50% of patients in both groups experienced adverse events, with no treatment-related serious toxicity.

IN PRACTICE:

“Tildrakizumab maintains improvements in scalp psoriasis for up to 52 weeks,” the authors wrote.

SOURCE:

Howard L. Sofen, MD, University of California Los Angeles, led the study, which was published online on December 22, 2024, in Journal of the American Academy of Dermatology.

LIMITATIONS:

This study excluded patients with predominantly scalp involvement and minimal whole body psoriasis, who might respond differently to the treatment. Results were obtained under controlled clinical conditions and may not be generalizable to clinical practice.

DISCLOSURES:

This study and analyses were funded by Sun Pharma. Sofen reported serving as a clinical investigator for various pharmaceutical companies, including Sun Pharma. Five authors were current or former employees of Sun Pharma and associated companies. Others also disclosed financial ties outside this work.
