Yahoo Finance UCB to share first presentations of BIMZELX® (bimekizumab-bkzx) two-year data in axial spondyloarthritis and psoriatic arthritis at EULAR 2024
Patients with non-radiographic axial spondyloarthritis (nr-axSpA) and those with ankylosing spondylitis (AS) treated with BIMZELX showed sustained and consistent clinical and patient-reported outcomes up to two years
Late-breaking data revealed that >90 percent of patients with AS treated with BIMZELX showed no spinal radiographic progression over two years, as defined by modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) change from baseline <2
Patients with psoriatic arthritis (PsA) treated with BIMZELX who were new to biologics, and those with prior inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR), showed sustained and consistent minimal disease activity (MDA) up to two years
ATLANTA, June 12, 2024 /PRNewswire/ -- UCB, a global biopharmaceutical company, today announced the first presentation of two-year data from the Phase 3 studies, BE MOBILE 1 and BE MOBILE 2, and the open-label extension (OLE), BE MOVING, evaluating BIMZELX, an interleukin (IL)-17A and IL-17F inhibitor, in the treatment of active non-radiographic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS), also known as radiographic axial spondyloarthritis. The impact of BIMZELX treatment on two-year radiographic progression in the spine of patients with AS will also be presented in a late-breaking oral presentation. In addition, the first two-year BIMZELX data in psoriatic arthritis (PsA) from the Phase 3 studies, BE OPTIMAL and BE COMPLETE, and the open-label extension, BE VITAL, are also announced today. These data are presented at the European Congress of Rheumatology, EULAR 2024, in Vienna, Austria, June 12–15.1,2,3,4
In the U.S., BIMZELX is approved for the treatment of moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.5 BIMZELX is not approved in the U.S. for the treatment of PsA, nr-axSpA, and AS. In the U.S., the efficacy and safety of BIMZELX in the treatment of PsA, nr-axSpA, and AS have not been established, and these are investigational indications.
"The bimekizumab new two-year data in axial spondyloarthritis and psoriatic arthritis presented at EULAR 2024 reinforce our belief in bimekizumab to provide long-term robust and sustained outcomes for patients with psoriatic arthritis and for patients across the full spectrum of axial spondyloarthritis," said Emmanuel Caeymaex, Executive Vice President, Head of Patient Impact, Chief Commercial Officer, UCB. "We are particularly excited to share new late-breaking data that highlights our commitment to demonstrate the long-term benefit of bimekizumab on disease progression in radiographic axial spondyloarthritis."
"The bimekizumab data in axial spondyloarthritis presented at EULAR 2024 showed that non-radiographic and radiographic axSpA patients achieved sustained suppression of inflammation over two years, and reported sustained improvements in symptoms which have a substantial impact on daily living including spinal pain, morning stiffness and fatigue," said Xenofon Baraliakos, Professor of Internal Medicine and Rheumatology, Ruhr-University Bochum, Bochum, Germany. "One of the long-term treatment goals in axSpA is the prevention of structural progression. Late-breaking data also shared at the congress showed that the majority of radiographic axial spondyloarthritis patients treated with bimekizumab had no spinal radiographic progression over two years."
"Minimal disease activity and remission are key treatment targets in the treatment of psoriatic arthritis," said Laura Coates, Associate Professor, Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, University of Oxford, UK. "New two-year data presented at EULAR 2024 showed that approximately 50% of patients treated with bimekizumab achieved sustained minimal disease activity and remission over two years. Improvements were observed across all patient-reported and most clinical components of minimal disease activity, with robust improvements in joint and skin outcomes."
Across the spectrum of axSpA, approximately one in two patients treated with BIMZELX over two years achieved and maintained a 40 percent or greater improvement in signs and symptoms of axSpA, Assessment of SpondyloArthritis international Society (ASAS40).1† At two years, approximately six in ten patients with either nr-axSpA or AS achieved Ankylosing Spondylitis Disease Activity Score (ASDAS) low disease activity (ASDAS <2.1) and three in ten achieved a state of inactive disease (ASDAS <1.3).1‡ Late-breaking data revealed that patients with AS treated with BIMZELX showed minimal spinal radiographic progression at two years, and there was a high proportion of non-progressors, including in those with baseline spinal damage. Furthermore, one-year results and post hoc analyses from BE MOBILE 1 and BE MOBILE 2 showed that treatment with BIMZELX substantially improved magnetic resonance imaging (MRI) inflammation, reduced erosions and increased backfill and fat in the sacroiliac joints of patients with nr-axSpA and AS, which may suggest evidence of tissue repair.6
In PsA, approximately one in two patients treated with BIMZELX who were new to biologics, and those with prior inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR) showed sustained achievement of minimal disease activity (MDA) over two years. Patients also achieved sustained remission up to two years as measured by the Disease Activity Index for Psoriatic Arthritis (DAPSA) remission (REM) or low disease activity (LDA) (REM≤4; REM+LDA≤14) responses and DAPSA change from baseline.4
Highlights from the BIMZELX two-year data in axSpA presented at EULAR 2024:
ASAS40: At Week 104, 49.2 percent of patients with nr-axSpA (n=254) and 53.9 percent (n=332) of patients with AS treated with BIMZELX achieved ASAS40.1†
Low Disease Activity: At Week 104, 61.2 percent of patients with nr-axSpA (n=254) and 63.4 percent of patients with AS (n=332) treated with BIMZELX achieved low disease activity (ASDAS<2.1).1‡
Inactive Disease: At Week 104, 31.6 percent of patients with nr-axSpA (n=254) and 31.3 percent‡ of patients with AS (n=332) achieved inactive disease (ASDAS <1.3).1‡
Radiographic Progression: At Week 104, the majority of patients with AS (157/190) treated with BIMZELX had no spinal radiographic progression as defined by mSASSS Change from Baseline (CfB) =0. The proportion of non-progressors was 85.3 percent (162/190), as defined by mSASSS CfB ≤0.5. The proportion of non-progressors was 92.1 percent (175/190), as defined by mSASSS CfB <2, which included 83.1 percent (69/83) of the patients who had existing structural damage (mSASSS ≥2) at baseline.2
Patient-Reported Outcomes: Treatment with BIMZELX demonstrated consistently sustained improvements in spinal pain, morning stiffness, and fatigue in patients with nr-axSpA and AS over two years, as reported by patients.3
Safety Profile: The safety profile of BIMZELX in axSpA over two years was consistent with previous studies with no new safety signals observed.1 To Week 104, 89.5 percent (514/574) of patients with axSpA had ≥1 treatment-emergent adverse event (TEAE) on BIMZELX.1 The most frequent TEAEs by exposure-adjusted incidence rate per 100 patient-years were SARS-CoV-2 infection (COVID-19; 13.2), nasopharyngitis (10.2), and upper respiratory tract infection (6.0).1
Highlights from the BIMZELX two-year data in PsA presented at EULAR 2024:
Minimal Disease Activity & Remission: At Week 104, 52.4 percent of biologic-naïve patients with PsA treated with BIMZELX (n=431) and 49.8 percent of biologic-naïve patients with PsA who switched from placebo to BIMZELX (n=281) at Week 16 achieved MDA.4† In patients in the adalimumab reference arm who switched to BIMZELX at Week 52, the MDA response at Week 52 was sustained to Week 104. At Week 88, 46.1 percent of TNFi-IR patients with PsA treated with BIMZELX (n=267) and 36.8 percent of TNFi-IR patients with PsA who switched from placebo to BIMZELX (n=133) at Week 16 achieved MDA.4† Trends were similar at Week 104/88 for achievement of DAPSA remission and low disease activity.4

About Axial Spondyloarthritis
Axial Spondyloarthritis, which includes both nr-axSpA and AS, is a chronic, immune-mediated, inflammatory disease.7 nr-axSpA is defined clinically by the absence of definitive x-ray evidence of structural damage to the sacroiliac joints.7 axSpA is a painful condition that primarily affects the spine and the joints linking the pelvis and lower spine (sacroiliac joints).7 The leading symptom of axSpA in a majority of patients is inflammatory back pain that improves with exercise but not with rest.7 Other common clinical features frequently include anterior uveitis, enthesitis, peripheral arthritis, psoriasis, inflammatory bowel disease and dactylitis.7 The overall prevalence of axSpA is 0.3 percent to 1.4 percent of adults.8,9 Approximately half of all patients with axSpA have nr-axSpA.7 axSpA onset usually occurs before the age of 45.7 Approximately 10 to 40 percent of patients with nr-axSpA progress to AS over 2 to 10 years.7
About BE MOBILE 1 and BE MOBILE 2
BE MOBILE 1 and BE MOBILE 2 were two Phase 3 studies evaluating the efficacy and safety of bimekizumab-bkzx in the treatment of nr-axSpA and AS, respectively.10 The primary endpoint in both studies was Assessment of SpondyloArthritis International Society 40 percent (ASAS40) response at Week 16.10 BE MOBILE 1 and BE MOBILE 2 comprised a 16-week double-blind treatment period followed by a 36-week maintenance period.10 In BE MOBILE 1 and BE MOBILE 2, patients were randomized to bimekizumab-bkzx (160 mg Q4W; n=128 for BE MOBILE 1 and n=221 for BE MOBILE 2) or to placebo (n=126 for BE MOBILE 1 and n=111 for BE MOBILE 2).10 Patients initially randomized to placebo were switched to bimekizumab-bkzx (160 mg Q4W) at Week 16.10 At Week 52, those who completed either study were eligible to be enrolled into BE MOVING.1,2 Of 254 patients with nr-axSpA and 332 patients with AS originally randomized to bimekizumab-bkzx or placebo in BE MOBILE 1 and 2, respectively, 494 patients entered BE MOVING at Week 52.1,2 By July 2023, 456 patients completed Week 104 (nr-axSpA n=189; AS n=267).1,2
About Psoriatic Arthritis
Psoriatic arthritis 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 and 6 percent to 41 percent of patients with psoriasis.11 Symptoms include joint pain and stiffness, skin plaques, swollen toes and fingers (dactylitis) and inflammation of the sites where tendons or ligaments insert into the bone (enthesitis).12
About BE OPTIMAL and BE COMPLETE
BE OPTIMAL and BE COMPLETE were two Phase 3 studies evaluating the efficacy and safety of bimekizumab-bkzx in the treatment of PsA.13,14 The primary endpoint in both studies was the proportion of patients reaching 50% or greater improvement in American College of Rheumatology criteria (ACR50) at Week 16 (non-responder imputation).13,14 BE OPTIMAL (bDMARD-naïve) and BE COMPLETE (TNFi–IR) assessed subcutaneous bimekizumab-bkzx 160 mg every four weeks (Q4W) in patients with PsA; both studies were placebo–controlled to Week 16, after which placebo patients switched to bimekizumab-bkzx.13,14 BE OPTIMAL included a reference arm (adalimumab 40 mg Q2W); adalimumab patients switched to bimekizumab-bkzx at Week 52 with no washout between treatments. BE OPTIMAL Week 52 and BE COMPLETE Week 16 completers were eligible for BE VITAL open-label extension.4 From BE OPTIMAL 83.3 percent of patients (n=710/852) and from BE COMPLETE 82.5 percent (n=330/400) completed Week 104 and Week 88, respectively.4 Outcomes are reported to Week 88 for BE COMPLETE because 18 (4.5%) had not yet attended their Week 100 visit.4

BIMZELX U.S. IMPORTANT SAFETY INFORMATION5
Suicidal Ideation and Behavior
BIMZELX® (bimekizumab-bkzx) may increase the risk of suicidal ideation and behavior (SI/B). A causal association between treatment with BIMZELX and increased risk of SI/B has not been established. Prescribers should weigh the potential risks and benefits before using BIMZELX in patients with a history of severe depression or SI/B. Advise monitoring for the emergence or worsening of depression, suicidal ideation, or other mood changes. If such changes occur, advise to promptly seek medical attention, refer to a mental health professional as appropriate, and re-evaluate the risks and benefits of continuing treatment.
Infections
BIMZELX may increase the risk of infections. Do not initiate treatment with BIMZELX in patients with any clinically important active infection until the infection resolves or is adequately treated. In patients with a chronic infection or a history of recurrent infection, consider the risks and benefits prior to prescribing BIMZELX. Instruct patients to seek medical advice if signs or symptoms suggestive of clinically important infection occur. If a patient develops such an infection or is not responding to standard therapy, monitor the patient closely and do not administer BIMZELX until the infection resolves.
Tuberculosis
Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with BIMZELX. Avoid the use of BIMZELX in patients with active TB infection. Initiate treatment of latent TB prior to administering BIMZELX. Consider anti-TB therapy prior to initiation of BIMZELX in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Closely monitor patients for signs and symptoms of active TB during and after treatment.
Liver Biochemical Abnormalities
Elevated serum transaminases were reported in clinical trials with BIMZELX. Test liver enzymes, alkaline phosphatase and bilirubin at baseline, periodically during treatment with BIMZELX and according to routine patient management. If treatment-related increases in liver enzymes occur and drug-induced liver injury is suspected, interrupt BIMZELX until a diagnosis of liver injury is excluded. Permanently discontinue use of BIMZELX in patients with causally associated combined elevations of transaminases and bilirubin. Avoid use of BIMZELX in patients with acute liver disease or cirrhosis.
Inflammatory Bowel Disease
Cases of inflammatory bowel disease (IBD) have been reported in patients treated with IL-17 inhibitors, including BIMZELX. Avoid use of BIMZELX in patients with active IBD. During BIMZELX treatment, monitor patients for signs and symptoms of IBD and discontinue treatment if new onset or worsening of signs and symptoms occurs.
Immunizations
Prior to initiating therapy with BIMZELX, complete all age-appropriate vaccinations according to current immunization guidelines. Avoid the use of live vaccines in patients treated with BIMZELX.
Most Common Adverse Reactions
Most common adverse reactions (≥1 percent) are upper respiratory infections, oral candidiasis, headache, injection site reactions, tinea infections, gastroenteritis, Herpes Simplex Infections, acne, folliculitis, other Candida infections, and fatigue.
