• Oral presentation from the CRIB study demonstrates minimal to no placental transfer of CIMZIA during pregnancy; poster from CRADLE study finds minimal to no transfer in breast milk
• Oral presentation of the first and only four-year radiographic and MRI imaging findings on CIMZIA efficacy for axial spondyloarthritis, including ankylosing spondylitis and non-radiographic axial spondyloarthritis
• Poster presentation of four-year data on control of psoriatic arthritis and its extra-articular manifestations in CIMZIA patients with and without prior anti-TNF exposure
• Oral presentation on romosozumab in osteoporosis
• Poster presentations on preclinical data supporting the contribution of IL-17F to inflammation as well as the effect of dual IL-17A and IL-17F neutralization with bimekizumab on joint and skin inflammation and bone formation
• Poster presentation on the selective PI3Kδ inhibitor seletalisib for autoimmune disease

Brussels, Belgium - 14 June, 00:01 CET - UCB, a global biopharmaceutical company focusing on immunology, neurology and bone treatment and research, is presenting data on CIMZIA (certolizumab pegol) and key pipeline molecules including bimekizumab, romosozumab, and seletalisib at the Annual European Congress of Rheumatology (EULAR) 2017 in Madrid, Spain (14 -17 June 2017).

Data highlights include an oral presentation on the results from CRIB, a prospective pharmacokinetic study showing minimal to no placental transfer from mother to fetus of CIMZIA during pregnancy. These groundbreaking findings, when considered in combination with those from a poster presentation on the CRADLE study showing minimal to no transfer of CIMZIA through breast milk, add to the clinical evidence for women with chronic inflammatory diseases and their treating physicians to make informed decisions regarding their treatment and care.

Presentations of long-term data in axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) will demonstrate UCB's commitment to bringing valuable solutions to these patients, including an oral presentation of the first four-year radiographic and MRI imaging data on CIMZIA efficacy across the full spectrum of the axSpA patient population. Long-term control of disease, through suppression of inflammation and prevention or slowing of new bone formation, is a major goal of the treatment of axSpA, including ankylosing spondylitis (AS) and non-radiographic axial spondylitis (nr-axSpA).

Other oral and poster presentations offer preclinical data that suggest the potential of bimekizumab and seletalisib for patients with chronic immune-mediated inflammatory diseases.

'UCB engages in pioneering research that has the potential to meaningfully improve patients' lives. Today this commitment drives us to extend the value of CIMZIA further than ever before for underserved patient populations, such as in axial spondyloarthritis and women of child bearing age with active chronic inflammatory diseases. This commitment also leads us to explore the potential of new treatments and disease management approaches for patients with unmet needs,' said Emmanuel Caeymaex, Head of Immunology and Executive Vice President at UCB. 'This is what is on display at EULAR 2017 this year and we are grateful to each of the countless patients and researchers in Europe and the U.S. who have helped to bring these findings to this important rheumatology meeting.'

UCB's 19 data presentations at EULAR demonstrate sustained and focused long-term research as well as new work on improving treatment outcomes and overall patient experience across several chronic immune-mediated inflammatory diseases, including rheumatoid arthritis (RA), PsA, and axSpA.

UCB will also sponsor two satellite symposia during EULAR. One symposium, titled 'Breaking the Fragility Fracture Cycle: Can We Step Up to The Challenge?' will be held Thursday, June 15, 2017, 17:30 - 19:00, Room N11/N12, and will focus on improving management and care for patients with fragility fractures. The other symposium, titled 'The Journey to Motherhood in Chronic Rheumatic Diseases' will be held Friday, June 16, 2017, 08:15 - 09 :45, Hall 7B, and will focus on the patient journey and the goals for patient care before, during, and after pregnancy in patients with chronic rheumatic diseases.

About Romosozumab
Romosozumab is an investigational bone-forming monoclonal antibody that is not currently approved by any regulatory authority for the treatment of osteoporosis. It is designed to work by inhibiting the protein sclerostin, and has a dual effect on bone, both increasing bone formation and decreasing bone resorption. 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 10,000 postmenopausal women with osteoporosis. Amgen and UCB are co-developing romosozumab.

About Bimekizumab
Bimekizumab is an investigational humanized IgG1 monoclonal antibody rationally designed to potently and selectively neutralize the biological function of both IL-17A and IL-17F, two key pro-inflammatory cytokines. IL-17A and IL-17F are closely related cytokines that are co-expressed at sites of inflammation and both independently co-operate with other cytokines to mediate chronic inflammatory responses driving many severe skin and joint diseases. Dose-ranging studies for bimekizumab have also started. Bimekizumab is not approved by any regulatory authority worldwide.

About Seletalisib
Seletalisib is a new chemical entity and is a potent and highly selective phosphoinositide 3 kinase delta (PI3Kδ) inhibitor with the potential for use in the treatment of immune-inflammatory diseases. Initial clinical investigations in healthy volunteers suggest that seletalisib is well tolerated at doses that are anticipated to have therapeutic potential and is suitable for oral, once-daily administration. Seletalisib is not approved by any regulatory authority worldwide.

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 methotrexate or when continued treatment with methotrexate is inappropriate.

CIMZIA is also indicated in the EU for the treatment of adult patients with severe active axial spondyloarthritis (axSpA), comprising:

• Ankylosing spondylitis (AS) - adults with severe active AS who have had an inadequate response to, or are intolerant to non-steroidal anti-inflammatory drugs (NSAIDs).
• Axial spondyloarthritis (axSpA) without radiographic evidence of AS - adults with severe active axSpA without radiographic evidence of AS but with objective signs of inflammation by elevated C-reactive protein (CRP) and/or Magnetic Resonance Imaging (MRI) who have had an inadequate response to, or are intolerant to NSAIDs.

CIMZIA is not recommended during pregnancy. A decision on whether to continue/discontinue breastfeeding or to continue/discontinue therapy with CIMZIA should be made taking into account the benefit of breastfeeding to the child and the benefit of CIMZIA therapy to the woman.

Important Safety Information about CIMZIA in the EU/EEA
CIMZIAwas 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 CIMZIAmust 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 hematologic 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.
