Positive Top-Line Results for bimekizumab in Second Phase 3 Psoriatic Arthritis Study

BRUSSELS and ATLANTA, Jan. 21, 2022 /PRNewswire/ -- 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 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 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

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, and its efficacy and safety have not been established for any indication in the U.S.

Forward looking statements UCB
This press release may contain forward-looking statements including, without limitation, statements containing the words "believes", "anticipates", "expects", "intends", "plans", "seeks", "estimates", "may", "will", "continue" and similar expressions. These forward-looking statements are based on current plans, estimates and beliefs of management. All statements, other than statements of historical facts, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial information, expected legal, arbitration, political, regulatory or clinical results or practices and other such estimates and results. By their nature, such forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties and assumptions which might cause the actual results, financial condition, performance or achievements of UCB, or industry results, to differ materially from those that may be expressed or implied by such forward-looking statements contained in this press release. Important factors that could result in such differences include: the global spread and impact of COVID-19, changes in general economic, business and competitive conditions, the inability to obtain necessary regulatory approvals or to obtain them on acceptable terms or within expected timing, costs associated with research and development, changes in the prospects for products in the pipeline or under development by UCB, effects of future judicial decisions or governmental investigations, safety, quality, data integrity or manufacturing issues; potential or actual data security and data privacy breaches, or disruptions of our information technology systems, product liability claims, challenges to patent protection for products or product candidates, competition from other products including biosimilars, changes in laws or regulations, exchange rate fluctuations, changes or uncertainties in tax laws or the administration of such laws, and hiring and retention of its employees. There is no guarantee that new product candidates will be discovered or identified in the pipeline, will progress to product approval or that new indications for existing products will be developed and approved. Movement from concept to commercial product is uncertain; preclinical results do not guarantee safety and efficacy of product candidates in humans. So far, the complexity of the human body cannot be reproduced in computer models, cell culture systems or animal models. The length of the timing to complete clinical trials and to get regulatory approval for product marketing has varied in the past and UCB expects similar unpredictability going forward. Products or potential products which are the subject of partnerships, joint ventures or licensing collaborations may be subject to differences disputes between the partners or may prove to be not as safe, effective or commercially successful as UCB may have believed at the start of such partnership. UCB' efforts to acquire other products or companies and to integrate the operations of such acquired companies may not be as successful as UCB may have believed at the moment of acquisition. Also, UCB or others could discover safety, side effects or manufacturing problems with its products and/or devices after they are marketed. The discovery of significant problems with a product similar to one of UCB's products that implicate an entire class of products may have a material adverse effect on sales of the entire class of affected products. Moreover, sales may be impacted by international and domestic trends toward managed care and health care cost containment, including pricing pressure, political and public scrutiny, customer and prescriber patterns or practices, and the reimbursement policies imposed by third-party payers as well as legislation affecting biopharmaceutical pricing and reimbursement activities and outcomes. Finally, a breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of UCB's data and systems.

Given these uncertainties, you should not place undue reliance on any of such forward-looking statements. There can be no guarantee that the investigational or approved products described in this press release will be submitted or approved for sale or for any additional indications or labelling in any market, or at any particular time, nor can there be any guarantee that such products will be or will continue to be commercially successful in the future.

UCB is providing this information, including forward-looking statements, only as of the date of this press release and it does not reflect any potential impact from the evolving COVID-19 pandemic, unless indicated otherwise. UCB is following the worldwide developments diligently to assess the financial significance of this pandemic to UCB. UCB expressly disclaims any duty to update any information contained in this press release, either to confirm the actual results or to report or reflect any change in its forward-looking statements with regard thereto or any change in events, conditions or circumstances on which any such statement is based, unless such statement is required pursuant to applicable laws and regulations.
