Brussels, Belgium – 21st January 2022 – 07:00 CET – Regulated Information – Inside Information – UCB, a global biopharmaceutical company, today announced positive top-line results from the Phase 3 BE COMPLETE study, which evaluated the efficacy and safety of BIMZELX® (bimekizumab) in the treatment of adults with active psoriatic arthritis, who were inadequate responders or intolerant to anti-tumor necrosis factor-alpha (anti-TNF-α) therapy.1
BE COMPLETE met its primary endpoint, demonstrating that significantly more patients treated with bimekizumab achieved 50 percent or greater improvement in signs and symptoms of disease from baseline, compared with placebo, as measured by the American College of Rheumatology (ACR) 50 response at week 16.1
The study also met all ranked secondary endpoints. Bimekizumab showed significant improvements over placebo at week 16 in physical function, as measured by Health Assessment Questionnaire-Disability Index (HAQ-DI); skin clearance, as measured by at least a 90 percent improvement in the Psoriasis Area and Severity Index (PASI90); physical health status, as measured by the Short Form 36-item Health Survey (SF-36) Physical Component Summary (PCS) score; and low disease activity, as measured by the Minimal Disease Activity (MDA) index.1
“Psoriatic arthritis is a chronic inflammatory condition affecting both the joints and skin. The positive top-line results from the Phase 3 BE COMPLETE study show the potential of bimekizumab to improve the signs and symptoms of active psoriatic arthritis in a patient population who were inadequate responders or intolerant to anti-TNF therapy,” said Dr Joseph F. Merola, MD, MMSc, Associate Professor, Harvard Medical School and Brigham and Women’s Hospital, Boston, MA, U.S.
“The BE COMPLETE results mark the latest positive data in a series of four Phase 3 readouts for bimekizumab in the treatment of psoriatic arthritis and axial spondyloarthritis. We believe that these consistent and robust results have the potential to elevate the standard of care for patients,” said Emmanuel Caeymaex, Executive Vice President, Immunology Solutions and Head of U.S., UCB. “Both psoriatic arthritis studies in the program used ACR50 as the primary outcome measure. The positive findings in both studies highlight the clinical potential of bimekizumab in psoriatic arthritis for both biologic naïve and anti-TNF therapy experienced patients.”
In BE COMPLETE, the safety profile of bimekizumab was consistent with safety data seen in previous studies with no new observed safety signals.1 The safety and efficacy of bimekizumab in psoriatic arthritis have not been established, and it is not approved for use in psoriatic arthritis by any regulatory authority worldwide.1
Full results from the BE COMPLETE study will be presented at upcoming medical conferences and published in a peer-reviewed medical journal.
The top-line results from the BE COMPLETE study build on the positive top-line interim analysis results from the Phase 3 BE OPTIMAL study in adults with active psoriatic arthritis, who were biologic disease-modifying anti-rheumatic drug (bDMARD) naïve, reported in November 2021.2 Based on these results, UCB plans to submit regulatory applications for bimekizumab in psoriatic arthritis in the United States and the European Union in Q3 2022.
About BE COMPLETE
BE COMPLETE is a randomized, multicenter, double-blind, placebo-controlled, parallel group, Phase 3 study designed to evaluate the efficacy and safety of bimekizumab in adults with active psoriatic arthritis who were inadequate responders or intolerant to anti-tumor necrosis factor-alpha (anti-TNF-α) therapy.3 BE COMPLETE enrolled 400 participants with disease for at least six months prior to screening, and a baseline tender joint count (TJC) ≥ three out of 68 and swollen joint count (SJC) ≥ three out of 66.3 All enrolled study participants had a history of inadequate response (lack of efficacy after at least three months of therapy at an approved dose) or intolerance to treatment with one or two tumor necrosis factor alpha (TNFα) inhibitors for either psoriatic arthritis or psoriasis.3 For additional details on the study, visit BE COMPLETE on clinicaltrials.gov.
About Psoriatic Arthritis
Psoriatic arthritis (PsA) is a serious, highly heterogeneous, chronic systemic inflammatory condition affecting both the joints and skin, with a prevalence of 0.05 percent to 0.25 percent of the population, and 6 percent to 41 percent of patients with psoriasis.4 Symptoms include joint pain and stiffness, skin plaques, swollen toes and fingers (dactylitis), and persistent inflammation of the sites where tendons or ligaments insert into the bone (enthesitis).5
About BIMZELX® (bimekizumab)
Bimekizumab is a humanized monoclonal IgG1 antibody that is designed to selectively and directly inhibit both interleukin 17A (IL-17A) and interleukin 17F (IL-17F), two key cytokines driving inflammatory processes.6
In the European Union (EU)/European Economic Area (EEA) and in Great Britain, BIMZELX® is indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy.7,8 In the U.S., bimekizumab is currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of moderate to severe plaque psoriasis in adults.
BIMZELX® ▼ (bimekizumab) EU/EEA Important Safety Information in Psoriasis
The most frequently reported adverse reactions with bimekizumab were upper respiratory tract infections (14.5%) (most frequently nasopharyngitis) and oral candidiasis (7.3%). Common adverse reactions (≥1/100 to <1/10) were oral candidiasis, tinea infections, ear infections, herpes simplex infections, oropharyngeal candidiasis, gastroenteritis, folliculitis, headache, dermatitis and eczema, acne, injection site reactions, fatigue. Elderly may be more likely to experience certain adverse reactions such as oral candidiasis, dermatitis and eczema when using bimekizumab.
Bimekizumab is contraindicated in patients with hypersensitivity to the active substance or any of the excipients and in patients with clinically important active infections (e.g. active tuberculosis).
Bimekizumab may increase the risk of infections. Treatment with bimekizumab must not be administered in patients with any clinically important active infection. Patients treated with bimekizumab should be instructed to seek medical advice if signs or symptoms suggestive of an infection occur. Prior to initiating treatment with bimekizumab, patients should be evaluated for tuberculosis (TB) infection. Bimekizumab should not be given in patients with active TB and patients receiving bimekizumab should be monitored for signs and symptoms of active TB.
Cases of new or exacerbations of inflammatory bowel disease have been reported with bimekizumab. Bimekizumab is not recommended in patients with inflammatory bowel disease. If a patient develops signs and symptoms of inflammatory bowel disease or experiences an exacerbation of pre-existing inflammatory bowel disease, bimekizumab should be discontinued and appropriate medical management should be initiated.
Serious hypersensitivity reactions including anaphylactic reactions have been observed with IL-17 inhibitors. If a serious hypersensitivity reaction occurs, administration of bimekizumab should be discontinued immediately and appropriate therapy initiated.
Live vaccines should not be given in patients treated with bimekizumab.
