BRUSSELS, Belgium I September 23, 2024 I
UCB, a global biopharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has approved BIMZELX
®
(bimekizumab-bkzx) for the treatment of adults with active psoriatic arthritis (PsA), adults with active non-radiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation, and adults with active ankylosing spondylitis (AS).
1
Bimekizumab-bkzx is the first approved treatment for these three indications that is designed to selectively inhibit two key cytokines driving inflammatory processes – interleukin 17A (IL-17A) and interleukin 17F (IL-17F).
1
These newly approved indications follow the first U.S. approval for BIMZELX
®
in October 2023 for the treatment of moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.

“The approval of BIMZELX in the U.S. across three new indications – active psoriatic arthritis, active non-radiographic axSpA with objective signs of inflammation, and active ankylosing spondylitis – highlights the clinical benefit of dual inhibition of both IL-17A and IL-17F for patients, and provides an opportunity for more people living with chronic inflammatory diseases to achieve meaningful outcomes,” said Emmanuel Caeymaex, Executive Vice President, Head of Patient Impact and Chief Commercial Officer, UCB. “In psoriatic arthritis and across the spectrum of axSpA, clinical study results and real-world experience outside the U.S. have highlighted that BIMZELX can help patients achieve high thresholds of clinical response that are rapid in onset and sustained up to two years.”
The FDA recommended dosage of bimekizumab for adult patients with active PsA, active nr-axSpA with objective signs of inflammation, and active AS is 160 mg by subcutaneous injection every four weeks.
1
For PsA patients with co-existent moderate to severe plaque psoriasis, the dosage and administration is the same as for patients with moderate to severe plaque psoriasis.

BIMZELX is currently available for eligible patients.
Bimekizumab-bkzx for the treatment of adults with active psoriatic arthritis
“In Phase 3 clinical studies, the clinically meaningful and consistent clinical response in patients who had a previous inadequate response to TNF inhibitors, and in patients who were new to biologics, suggest that bimekizumab-bkzx has the potential to be an important new treatment option in our armamentarium for adults with psoriatic arthritis,” said Joseph F. Merola, MD, MMSc, Professor, Dermatologist, Rheumatologist, and Investigator, BE OPTIMAL and BE COMPLETE. “The approval of bimekizumab-bkzx for the treatment of active psoriatic arthritis provides a new, differentiated treatment option for the rheumatology and dermatology communities.”
The approval of bimekizumab-bkzx for adult patients with active PsA is supported by data from the Phase 3 BE OPTIMAL and BE COMPLETE studies, in which bimekizumab-bkzx met the primary endpoint of American College of Rheumatology 50 (ACR50) response at Week 16 versus placebo, and all ranked secondary endpoints.
2,3
Consistent results were seen across both biologic-naïve and TNF inhibitor inadequate-responder (TNFi-IR) populations.
2,3
Clinical responses achieved at Week 16 were sustained to Week 52 in BE OPTIMAL and in BE COMPLETE, and its open-label extension, as assessed by ACR50 (primary endpoint), Psoriasis Area and Severity Index 90 (PASI90, ranked secondary endpoint), minimal disease activity (MDA; ranked secondary endpoint) and PASI100, i.e., complete skin clearance (other endpoint).
4,5
“Psoriatic arthritis can severely impact a person’s quality of life. With joint pain and stiffness, daily activities can become burdensome. New treatment options are always a welcome addition, and they offer some renewed hope for relief from the symptoms and health impacts of PsA,” said Leah M. Howard, J.D., the President and CEO of the National Psoriasis Foundation, U.S.
Bimekizumab-bkzx for the treatment of adults with active nr-axSpA and active AS
“In the Phase 3 clinical studies, patients treated with bimekizumab-bkzx saw improvements in signs and symptoms and key measures of disease activity at Week 16 which were sustained to one year and consistent across patients with non-radiographic axial spondyloarthritis and ankylosing spondylitis,” said Atul Deodhar, MD, Professor of Medicine and Medical Director of rheumatology clinics at the Division of Arthritis & Rheumatic Diseases, Oregon Health & Science University, Portland, Oregon, U.S. “The U.S. rheumatology community welcomes the approval of bimekizumab-bkzx for use across the entire spectrum of axial spondyloarthritis, especially given that there are few options approved currently to treat both non-radiographic axial spondyloarthritis and ankylosing spondylitis.”
The approvals of bimekizumab-bkzx for adult patients with active nr-axSpA with objective signs of inflammation, and active AS are supported by data from the Phase 3 BE MOBILE 1 and BE MOBILE 2 studies, respectively.
6,7
In both studies, bimekizumab-bkzx met the primary endpoint of Assessment of SpondyloArthritis international Society 40 (ASAS40) response at Week 16 compared with placebo, and all ranked secondary endpoints.
6,7
ASAS40 responses were consistent across TNFi-naïve and TNFi-inadequate responder patients.
6,7
Clinical responses achieved at Week 16 were sustained in both patients with nr-axSpA and AS to Week 52 as assessed by ASAS40, ranked secondary and other endpoints.
6,7
“People living with non-radiographic axial spondyloarthritis and ankylosing spondylitis experience pain, stiffness and fatigue that can limit their daily activities, ability to work, and quality of life,” said Seth Ginsberg, Co-Founder and President, Global Health Living Foundation and CreakyJoints, U.S. “A new treatment option offers the opportunity for more patients to reach their treatment goals.”
Notes to Editors:
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 0.02 percent to 0.25 percent of the population.
8
PsA affects approximately 30 percent of people living with psoriasis.
9
Symptoms include joint pain and stiffness, skin plaques, swollen toes and fingers (dactylitis), inflammation of the sites where tendons or ligaments insert into the bone (enthesitis), and inflammatory axial involvement.
10
About BE OPTIMAL and BE COMPLETE
2,3,4,5
Bimekizumab-bkzx (160 mg every four weeks) was evaluated in adult patients with active psoriatic arthritis (PsA) in two Phase 3 multicentre, randomized, double-blind, placebo-controlled studies (BE OPTIMAL and BE COMPLETE). The BE OPTIMAL study evaluated 852 patients not previously exposed to any biologic disease-modifying anti-rheumatic drug (bDMARD-naïve) for the treatment of PsA. The BE COMPLETE study evaluated 400 patients with an inadequate response or intolerance to treatment with one or two tumour necrosis factor alpha inhibitors (TNFi-IR) for the treatment of PsA.
Key findings from the Phase 3 Clinical Development Program:
In PsA, the most common (≥ 2 percent) adverse reactions with bimekizumab-bkzx are upper respiratory tract infections, oral candidiasis, headache, diarrhea and urinary tract infection.

About Axial Spondyloarthritis
Axial spondyloarthritis (axSpA), which includes both non-radiographic axSpA (nr-axSpA) and ankylosing spondylitis (AS), also known as radiographic axSpA (r-axSpA), is a chronic, immune-mediated, inflammatory disease.
11
Non-radiographic-axSpA (nr-axSpA) is defined clinically by the absence of definitive x-ray evidence of structural damage to the sacroiliac joints.
11
axSpA is a painful condition that primarily affects the spine and the joints linking the pelvis and lower spine (sacroiliac joints).
11
The leading symptom of axSpA in a majority of patients is inflammatory back pain that improves with exercise, but not with rest.
11
Other common clinical features frequently include anterior uveitis, enthesitis, peripheral arthritis, psoriasis, inflammatory bowel disease, and dactylitis.
11
The overall prevalence of axSpA is up to 1.4 percent of adults.
12,13
Approximately half of all patients with axSpA are patients with nr-axSpA.
11
Axial spondyloarthritis onset usually occurs before the age of 45.
11
Approximately 10 to 40 percent of patients with nr-axSpA progress to ankylosing spondylitis over 2 to 10 years.

The most frequently reported adverse reactions with bimekizumab were upper respiratory tract infections (14.5%, 14.6%, 16.3%, 8.8% in plaque psoriasis, psoriatic arthritis, axial spondyloarthritis (axSpA) and hidradenitis suppurativa, respectively) and oral candidiasis (7.3%, 2.3%, 3.7%, 5.6% in PSO, PsA, axSpA and HS, respectively). Common adverse reactions (≥1/100 to <1/10) were oral candidiasis, tinea infections, ear infections, herpes simplex infections, oropharyngeal candidiasis, gastroenteritis, folliculitis, vulvovaginal mycotic infection (including vulvovaginal candidiasis), headache, rash, 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 to 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 initiated 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. If a patient develops an infection the patient should be carefully monitored. If the infection becomes serious or is not responding to standard therapy, treatment should be discontinued until the infection resolves. Prior to initiating treatment with bimekizumab, patients should be evaluated for tuberculosis (TB) infection. Bimekizumab should not be given in patients with active TB. 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.
