ORLANDO – The interleukin-17A inhibitor ixekizumab was associated with superior efficacy and safety when compared with ustekinumab at 24 weeks, a head-to-head trial of the two monoclonal antibodies in plaque psoriasis has shown.
The 24-week data from the IXORA-S trial were presented during a late-breaking clinical trial session at the annual meeting of the American Academy of Dermatology by Kristian Reich, MD, PhD, a founder of SCIderm in Hamburg, Germany.
At 24 weeks, 49% in the ixekizumab arm achieved a Psoriasis Area and Severity Index (PASI) 100 level of skin clearance, compared with 24% in the ustekinumab arm (P = .001). Ixekizumab treatment also reached significantly higher skin clearances than ustekinumab at 24 weeks at the level of PASI 90 (83% vs. 59%; P less than .001) and PASI 75 (91% vs. 82%; P = .015).
Treatment with ixekizumab produced a Static Physician’s Global Assessment (sPGA) score of 0 in 54% at 24 weeks, compared with 24% with ustekinumab (P less than .001). A sPGA score of 0 or 1 occurred in 87% of patients who took ixekizumab and in 59% of the ustekinumab group.
An improvement of 4 or more points in the pruritus Numeric Rating Scale was reported by 86% of ixekizumab patients at 24 weeks, compared with 72% of those who took ustekinumab (P = .018).
Dr. Reich reported that there were no deaths or any significant differences in overall treatment-related adverse events across both arms, although he cautioned against putting too much stock in 24-week safety data. “I hesitate to show safety data for only 300 patients at 24 weeks, but it’s good to see here that there doesn’t seem to be a difference. I still would want to see larger patient numbers and more long-term data,” he said.
Dr. Reich had numerous disclosures, including honoraria for serving as a speaker for Eli Lilly, the sponsor of this trial.

AT AAD 2017
Key clinical point:
Major finding: At 24 weeks, ixekizumab was associated with significantly better PASI response rates and reduction in itch than ustekinumab in patients with moderate to severe plaque psoriasis.
Data source: Head-to-head trial of 302 adults with moderate to severe plaque psoriasis treated with either ixekizumab or ustekinumab.
Disclosures: Dr. Reich had numerous disclosures, including honoraria for serving as a speaker for Eli Lilly, the sponsor of this trial.
