As the first dual-specific IL-17 A/F inhibitor to treat plaque psoriasis, bimekizumab could be more effective than inhibitors of IL-17A only at reducing skin and joint inflammation as well as pathological bone formation, which are the primary contributors to the symptomatic burden of psoriasis, and with fewer side effects than some current treatment options, including a pan-IL-17 inhibitor. Prior approvals for the treatment of moderate to severe plaque psoriasis by the European Commission (EC), Japan’s Ministry of Health, Labour and Welfare (MHLW), Health Canada and Australia’s Therapeutic Goods Administration bode well for approval by the U.S. Food and Drug Administration (FDA).
Bimekizumab is the first dual IL-17 A/F inhibitor to treat moderate to severe plaque psoriasis. Phase 3 trial results showed superior skin clearance outcomes than existing treatments. Its less-frequent dosing schedule and good safety profile will likely be attractive to clinicians and patients.
