Report summary
The FDA recommended approval for AbbVie Inc.'s Biologics License Application (BLA) 761105 for Skyrizi (risankizumab), an IL-23 antagonist, for treating moderate to severe plaque psoriasis in adults. Extensive Phase 2 and 3 trials demonstrated risankizumab's superior efficacy over placebo and active comparators (ustekinumab, adalimumab) in achieving significant improvements in PASI 90 and sPGA 0/1 scores, with durable responses up to Week 52. The safety profile indicated no increased risk of mortality, malignancy, SIB, or MACE, though a higher incidence of infections compared to placebo was noted. Immunogenicity was assessed, and the proposed 150 mg dosing regimen was deemed appropriate. Preclinical and clinical pharmacology, including pharmacokinetics and toxicology, supported the drug's profile. The Psoriasis Symptom Scale (PSS) was validated for assessing symptoms. Post-marketing studies are required for long-term safety monitoring.
