UCB Announces European Commission Approval of BIMZELX (Bimekizumab) for the Treatment of Adults With Moderate to Severe Plaque Psoriasis

· BIMZELX (bimekizumab) is the first approved treatment for moderate to severe plaque psoriasis that is designed to selectively and directly inhibit both IL-17A and IL-17F
· The approval in the European Union represents the first marketing authorization for UCB's new psoriasis treatment worldwide
· Approval is supported by three Phase 3 trials where bimekizumab demonstrated superior levels of skin clearance compared to placebo, ustekinumab and adalimumab, and was generally well-tolerated 
· Bimekizumab is testament to UCB's commitment to advancing science in immuno-dermatology, addressing unmet needs and improving patient outcomes

BRUSSELS, Belgium I August 24, 2021 I UCB, a global biopharmaceutical company, today announced that the European Commission (EC) has granted marketing authorization for BIMZELX® (bimekizumab) for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy.1 Bimekizumab is the first approved treatment in the European Union (EU) for moderate to severe plaque psoriasis that is designed to selectively and directly inhibit both IL-17A and IL-17F, two key cytokines driving inflammatory processes.1

Bimekizumab is approved at a recommended dose of 320 mg, administered by two subcutaneous injections every four weeks to week 16 and every eight weeks thereafter.1 For some patients with a body weight ≥120 kg who did not achieve complete skin clearance at week 16, 320 mg every 4 weeks after week 16 may further improve treatment response.1

“The approval of BIMZELX in Europe is the first marketing authorization for this new psoriasis treatment worldwide and represents a landmark moment for the dermatology community and UCB. Our ambition is to transform the lives of people living with severe diseases, and we are incredibly proud to bring a new treatment option to people living with moderate to severe plaque psoriasis in Europe. We believe that bimekizumab has the potential to raise expectations of what psoriasis treatment can deliver.” said Emmanuel Caeymaex, Executive Vice President, Immunology Solutions and Head of US, UCB. 

Psoriasis can have a considerable physical and psychological impact on patients, as well as being detrimental to their quality of life, potentially affecting work, recreation, relationships, family and social life.2 A cross-sectional patient survey showed at least 90 percent of patients with moderate to severe plaque psoriasis place a high value on treatment which provides clear skin, a sustained response and rapid onset of action.3 In addition, a real-world study showed that gaining completely clear skin can make a meaningful difference to the impact psoriasis has on patients' health-related quality of life.4 

“In the pivotal Phase 3 studies patients treated with bimekizumab achieved superior levels of skin clearance compared to those treated with placebo, adalimumab and ustekinumab, and in the Phase 3b study, treatment with bimekizumab resulted in greater levels of skin clearance than secukinumab. Across studies, about 60 percent of bimekizumab-treated patients achieved complete skin clearance at week 16, and this response was maintained for up to a year.” said Professor Richard Warren, Salford Royal NHS Foundation Trust and The University of Manchester, UK. “The approval of bimekizumab in the EU provides a welcome new treatment option that may help more patients with moderate to severe plaque psoriasis to achieve their treatment goals.”

The European Commission approval follows a positive opinion granted in June 2021 by the European Medicines Agency's Committee for Medicinal Products for Human Use. The approval is supported by positive results from three Phase 3 studies, which evaluated the efficacy and safety of bimekizumab in 1,480 patients with moderate to severe plaque psoriasis.1 Full findings from the Phase 3 BE READY and BE VIVID studies are published in The Lancet, and the results of the Phase 3 BE SURE study are published in The New England Journal of Medicine.5,6,7 

The approval from the European Commission is valid in all 27 member states of the EU, as well as Iceland, Liechtenstein, and Norway. Bimekizumab is currently under review by the U.S. Food & Drug Administration (FDA) for the treatment of adults with moderate to severe plaque psoriasis. Regulatory reviews are also underway in Australia, Canada, Great Britain and Japan. 

Notes to Editors:

About the Phase 3 Psoriasis Clinical Development Program
The efficacy and safety of bimekizumab were evaluated in three Phase 3 studies, versus placebo and ustekinumab (BE VIVID), versus placebo (BE READY) and versus adalimumab (BE SURE).5,6,7 All studies met their co-primary endpoints and all ranked secondary endpoints.5,6,7

Patients treated with bimekizumab achieved superior levels of skin clearance at week 16, compared to those who received ustekinumab (ranked secondary endpoint, BE VIVID; pless than 0.0001), placebo (co-primary endpoint, BE READY and BE VIVID; pless than 0.0001) and adalimumab (co-primary endpoint, BE SURE; pless than 0.001), as measured by at least a 90 percent improvement in the Psoriasis Area & Severity Index (PASI 90) and an Investigator's Global Assessment (IGA) response of clear or almost clear skin (IGA 0/1).5,6,7 Clinical responses achieved with bimekizumab at week 16 were maintained up to one year in all studies.5,6,7 The most frequently reported adverse reactions in the clinical studies were upper respiratory tract infections (14.5 percent) (most frequently nasopharyngitis) and oral candidiasis (7.3 percent).1 For additional information on the bimekizumab Phase 3 clinical trial program, in psoriasis, please refer to the peer-reviewed publications and visit

About BIMZELX® (bimekizumab) in the EU
Bimekizumab is a humanized IgG1 monoclonal antibody that selectively binds with high affinity to IL-17A, IL-17F and IL-17AF cytokines, blocking their interaction with the IL-17RA/IL-17RC receptor complex.1 Elevated concentrations of IL-17A and IL-17F have been implicated in the pathogenesis of several immune-mediated inflammatory diseases including plaque psoriasis.1 Bimekizumab inhibits these proinflammatory cytokines, resulting in the normalization of skin inflammation and as a consequence improvement in clinical symptoms associated with psoriasis.

Bimzelx® ▼ (bimekizumab) EU/EEA* Important Safety Information
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 less than 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.

*EU/EEA means European Union/European Economic Area

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.

Please consult the summary of product characteristics in relation to other side effects, full safety and prescribing information.
