Late-Breaking Data: Skyrizi Achieves Superior Rates of Complete Skin Clearance for Psoriasis Compared to Secukinumab at 52 Weeks
New late-breaking Phase 3b head-to-head data show superior rates of skin clearance for AbbVie's risankizumab-rzaa (Skyrizi) compared to secukinumab (Cosentyx) at week 52. Sixty-six percent of psoriasis patients receiving Skyrizi achieved completely clear skin—100 percent clearance in the Psoriasis Area and Severity Index (PASI 100)—versus 40 percent of patients receiving secukinumab at week 52.
These new head-to-head results from the IMMerge Phase 3b open-label study were shared during an online late-breaking presentation during the American Academy of Dermatology (AAD) Virtual 2020 Annual Meeting. AbbVie previously announced top-line results from this study in January.
"I’ve seen first-hand how achieving and maintaining completely clear skin can have an incredibly positive impact on the lives of my psoriasis patients,” says chief investigator Richard B. Warren, MD, PhD, professor and honorary consultant dermatologist at the Dermatology Centre Salford Royal NHS Foundation Trust, University of Manchester. “These new data are critical as they underscore that complete skin clearance is a realistic treatment goal for people living with psoriasis.”
Skyrizi met both PASI 90 primary endpoints of non-inferiority to secukinumab at week 16 and superiority to secukinumab at week 52. At week 16, 74 percent of Skyrizi-treated patients achieved PASI 90 compared to 66 percent of secukinumab-treated patients. Of patients treated with Skyrizi, 87 percent achieved PASI 90 at week 52 compared to 57 percent of patients treated with secukinumab.
Additional results demonstrated a significantly higher proportion of patients treated with Skyrizi achieved a static Physician Global Assessment (sPGA) score of clear or almost clear (sPGA 0/1) compared to those treated with secukinumab at week 52 (88 percent versus 58 percent, respectively).
Current safety data available demonstrated that the safety profile of Skyrizi was consistent with that seen in previously reported studies, with no new safety signals observed through week 52.1-4 The rates of adverse events (AEs) were comparable between Skyrizi and secukinumab. The most common AEs were nasopharyngitis, upper respiratory tract infection, headache, arthralgia and diarrhea. The rates of serious AEs were 5.5 percent in the Skyrizi group and 3.7 percent in the secukinumab group. Adverse events leading to discontinuation of the study drug were 1.2 percent in the Skyrizi group and 4.9 percent in the secukinumab group. There were no deaths in either treatment group.
Skyrizi is part of a collaboration between Boehringer Ingelheim and AbbVie, with AbbVie leading development and commercialization globally.
