New UCB Data Presented at the Annual European Congress of Rheumatology (EULAR 2018) Serves Key Patient Populations Including Ankylosing Spondylitis, Psoriatic Arthritis, and Women with Chronic Inflammatory Diseases

- UCB, a global biopharmaceutical company focusing on immunology, neurology and bone treatment and research, will be presenting new data on CIMZIA® (certolizumab pegol) and key pipeline molecules bimekizumab and romosozumab at the Annual European Congress of Rheumatology (EULAR 2018), taking place in Amsterdam, June 13-16, 2018.      (Logo: https://mma.prnewswire.com/media/683106/UCB_Logo.jpg ) As a part of a late-breaking oral presentation, week 12 findings from the BE AGILE study will be presented for the first time, revealing the promising treatment effect of bimekizumab in patients living with ankylosing spondylitis (AS) and suggesting the potential breakthrough value of neutralizing IL-17F in addition to IL-17A. A separate presentation of long-term findings from RAPID-PsA on CIMZIA in psoriatic arthritis (PsA) will focus on the sustained achievement of stringent clinical outcomes, with a substantial proportion of patients achieving complete remission or very low disease activity. An additional oral presentation will offer insight into the positive effect in building bone with one year of romosozumab. "We are proud to present impressive findings on our pipeline molecules as well as the sustained value of CIMZIA in populations with specific treatment needs, such as women of childbearing age and patients with PsA and AS. The data that will be presented this week exemplify our mission to understand the needs of underserved patient populations, and connect them with scientific advancements that can provide real and immediate impact," said Emmanuel Caeymaex, Head of Immunology and Executive Vice President, Immunology Patient Value Unit, UCB. "We are committed to serving as partners in care by understanding and supporting patients and rheumatologists, who are engaging especially challenging treatment situations, so we can bring the broadest possible value to patients in need." Additional presentations include survey findings from both patients and healthcare professionals (HCP) on specific challenges involved in the treatment of chronic inflammatory diseases in women of childbearing age. Findings from the patient survey, "Fears and Misconceptions of Women with Chronic Rheumatic Disease on Their Journey to Motherhood," suggest that many women's decisions to delay pregnancy or interrupt their treatment may be linked to the need for greater awareness of disease management options and earlier consultation with their HCPs. Also to be presented are findings from a SERMO survey of practicing HCPs, exploring the physician perspective on the challenges specific to treating women with chronic inflammatory diseases during family planning. Results from the largest published cohort of pregnant women exposed to an anti-TNF during pregnancy that will be presented at EULAR 2018 confirm that patients treated with certolizumab pegol did not experience increased risk of major congenital malformations compared to the general population nor an increased risk of fetal death. Real world experiences of patients living with rheumatoid arthritis (RA) are explored in a poster presentation featuring analysis of data from the ArthritisPower Registry. Data suggest that rheumatologists tended to forego treatment changes, even when disease control goals were not met, with patients usually deferring to their HCPs. Other CIMZIA data featured at EULAR 2018 include data on ava, the auto-injection e-device, and the impact of the Coach@Home patient support program. In addition to 11 data presentations, UCB will be sponsoring two satellite symposia highlighting research and innovations in the treatment landscapes of osteoporosis and axial spondyloarthritis (axSpA). The data presented by UCB at EULAR 2018 showcase the company's commitment to connecting scientific innovation and insights into real-world patient goals and unmet needs to make a lasting difference in the lives of patients.

Chan, R. Y. Suruki, J. L. Stark, H. Yun, S. A. R. Siegel, L. Chen, M. Yassine, J. R. Curtis About Bimekizumab   Bimekizumab is a novel humanized monoclonal IgG1 antibody that potently and selectively neutralizes both IL-17A and IL-17F, two key cytokines driving inflammatory processes. IL-17A and IL-17F have overlapping pro-inflammatory functions and independently cooperate with other inflammatory mediators to drive chronic inflammation and damage across multiple tissues.  Previous early Phase clinical studies in psoriasis and psoriatic arthritis have suggested that neutralizing IL-17F in addition to IL-17A with bimekizumabmay provide a new targeted approach for the treatment of immune-mediated inflammatory diseases. Preclinical results in disease-relevant cells have shown that dual neutralization of both IL-17A and IL-17F reduces skin and joint inflammation, as well as pathological bone formation to an extent greater than inhibition of IL-17A or IL-17F alone.[i],[ii],[iii] UCB is studying bimekizumab in psoriasis, psoriatic arthritis and ankylosing spondylitis. Bimekizumab is not approved by any regulatory authority worldwide. About Romosozumab   Romosozumab is an investigational bone-forming monoclonal antibody and is not approved by any regulatory authority for the treatment of osteoporosis. It is designed to work by inhibiting the activity of sclerostin, which enables romosozumab to increase bone formation and reduce bone resorption simultaneously. Romosozumab is being studied for its potential to reduce the risk of fractures in an extensive global Phase 3 program. This program includes two large fracture trials comparing romosozumab to either placebo or active comparator in more than 11,000 postmenopausal women with osteoporosis. Amgen and UCB are co-developing romosozumab. About CIMZIA® in the EU/EEA   In the EU, CIMZIA® in combination with methotrexate (MTX) is indicated for the treatment of moderate to severe active RA in adult patients inadequately responsive to disease-modifying anti-rheumatic drugs (DMARDs) including MTX. CIMZIA can be given as monotherapy in case of intolerance to MTX or when continued treatment with MTX is inappropriate. CIMZIA in combination with MTX is also indicated for the treatment of severe, active and progressive RA in adults not previously treated with MTX or other DMARDs. CIMZIA has been shown to reduce the rate of progression of joint damage as measured by X-ray and to improve physical function, when given in combination with MTX. CIMZIA, in combination with MTX, is also indicated for the treatment of active psoriatic arthritis in adults when the response to previous DMARD therapy has been inadequate. CIMZIA can be given as monotherapy in case of intolerance to MTX or when continued treatment with MTX is inappropriate. CIMZIA is also indicated in the EU for the treatment of adult patients with severe active axial spondyloarthritis (axSpA), comprising: Important Safety Information about CIMZIA® in the EU/EEA    CIMZIA® was studied in 4,049 patients with rheumatoid arthritis (RA) in controlled and open label trials for up to 92 months. The commonly reported adverse reactions (1-10%) in clinical trials with CIMZIA® and post-marketing were viral infections (includes herpes, papillomavirus, influenza), bacterial infections (including abscess), rash, headache (including migraine), asthaenia, leukopaenia (including lymphopaenia, neutropaenia), eosinophilic disorder, pain (any sites), pyrexia, sensory abnormalities, hypertension, pruritus (any sites), hepatitis (including hepatic enzyme increase), injection site reactions, and nausea. Serious adverse reactions include sepsis, opportunistic infections, tuberculosis, herpes zoster, lymphoma, leukaemia, solid organ tumours, angioneurotic oedema, cardiomyopathies (includes heart failure), ischemic coronary artery disorders, pancytopaenia, hypercoagulation (including thrombophlebitis, pulmonary embolism), cerebrovascular accident, vasculitis, hepatitis/hepatopathy (includes cirrhosis), and renal impairment/nephropathy (includes nephritis). In RA controlled clinical trials, 4.4% of patients discontinued taking CIMZIA® due to adverse events vs. 2.7% for placebo. CIMZIA® is contraindicated in patients with hypersensitivity to the active substance or any of the excipients, active tuberculosis or other severe infections such as sepsis or opportunistic infections or moderate-to-severe heart failure. Serious infections including sepsis, tuberculosis and opportunistic infections have been reported in patients receiving CIMZIA®. Some of these events have been fatal. Monitor patients closely for signs and symptoms of infections including tuberculosis before, during, and after treatment with CIMZIA®. Treatment with CIMZIA® must not be initiated in patients with a clinically important active infection. If an infection develops, monitor carefully and stop CIMZIA® if infection becomes serious. Before initiation of therapy with CIMZIA®, all patients must be evaluated for both active and inactive (latent) tuberculosis infection. If active tuberculosis is diagnosed prior to or during treatment, CIMZIA® therapy must not be initiated and must be discontinued. If latent tuberculosis is diagnosed, appropriate anti-tuberculosis therapy must be started before initiating treatment with CIMZIA®. Patients should be instructed to seek medical advice if signs/symptoms (e.g. persistent cough, wasting/weight loss, low grade fever, listlessness) suggestive of tuberculosis occur during or after therapy with CIMZIA®. Reactivation of hepatitis B has occurred in patients receiving a TNF-antagonist including CIMZIA® who are chronic carriers of the virus (i.e. surface antigen positive). Some cases have had a fatal outcome. Patients should be tested for HBV infection before initiating treatment with CIMZIA®. Carriers of HBV who require treatment with CIMZIA® should be closely monitored and in the case of HBV reactivation CIMZIA® should be stopped and effective anti-viral therapy with appropriate supportive treatment should be initiated. TNF-antagonists including CIMZIA® may increase the risk of new onset or exacerbation of clinical symptoms and/or radiographic evidence of demyelinating disease; of formation of autoantibodies and uncommonly of the development of a lupus-like syndrome; of severe hypersensitivity reactions. If a patient develops any of these adverse reactions, CIMZIA® should be discontinued and appropriate therapy instituted. With the current knowledge, a possible risk for the development of lymphomas, leukaemia or other malignancies in patients treated with a TNF-antagonist cannot be excluded. Rare cases of neurological disorders, including seizure disorder, neuritis and peripheral neuropathy, have been reported in patients treated with CIMZIA®. Adverse reactions of the haematologic system, including medically significant cytopaenia, have been infrequently reported with CIMZIA®. Advise all patients to seek immediate medical attention if they develop signs and symptoms suggestive of blood dyscrasias or infection (e.g., persistent fever, bruising, bleeding, pallor) while on CIMZIA®. Consider discontinuation of CIMZIA® therapy in patients with confirmed significant haematological abnormalities. The use of CIMZIA® in combination with anakinra or abatacept is not recommended due to a potential increased risk of serious infections. As no data are available, CIMZIA® should not be administered concurrently with live vaccines. The 14-day half-life of CIMZIA® should be taken into consideration if a surgical procedure is planned. A patient who requires surgery while on CIMZIA® should be closely monitored for infections. CIMZIA® was studied in 325 patients with active axial spondyloarthritis (axSpA) in a placebo-controlled clinical trial for up to 30 months and in 409 patients with psoriatic arthritis (PsA) in a placebo-controlled clinical trial for up to 30 months. The safety profile for axSpA and PsA patients treated with CIMZIA® was consistent with the safety profile in RA and previous experience with CIMZIA®.
