BIMZELX® (bimekizumab) is the first and only treatment approved by Health Canada for eligible patients with active psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) that directly and selectively inhibits two key inflammatory proteins, IL-17A and IL-17F.1 Health Canada's approval is supported by Phase III clinical trial data which found BIMZELX provided significant improvement across key disease severity indicators.2,3,4 The approval of BIMZELX for adults with active PsA or axSpA demonstrates UCB's ongoing commitment to advancing science in immuno-dermatology and rheumatological conditions, addressing unmet patient needs and improving clinical outcomes. OAKVILLE, ON, March 14, 2024 /CNW/ - Today, UCB Canada Inc. is pleased to announce that BIMZELX® (bimekizumab injection) has received authorization from Health Canada for two new indications. On February 23, 2024, BIMZELX was approved for the treatment of adults with active psoriatic arthritis (PsA) and on March 11, 2024, the therapy also received approval for the treatment of adults with axial spondyloarthritis (axSpA). BIMZELX is a monoclonal antibody belonging to a group of medicines called interleukin (IL) inhibitors. Monoclonal antibodies are proteins that recognize and bind specifically to certain proteins in the body. This medicine works by reducing the activity of two proteins called IL-17A and IL-17F, which are present at increased levels in diseases such as PsA and axSpA.1 BIMZELX is also the first and only biologic that directly inhibits both IL-17A and IL-17F to be approved in Canada. "We are delighted with the approval of BIMZELX in Canada for both psoriatic arthritis and axial spondyloarthritis, and its first marketing authorization for these new indications in North America," said Lionel Houle, Head of Immunology, UCB Canada. "This follows our first product approval in moderate to severe plaque psoriasis. Our sights are set on innovative scientific solutions that can raise the standard of care in the lives of patients. We are proud to bring this new treatment option to people living with these illnesses in Canada, and believe that BIMZELX has the potential to help many patients living with the painful and debilitating symptoms of both conditions." Both Health Canada approvals are based on Phase III data which supports BIMZELX's role as an innovative treatment option for patients with PsA and axSpA, including non-radiographic axSpA (nr-axSpA) and ankylosing spondylitis (AS, also known as radiographic axSpA (r-axSpA)).2,3,4 "Psoriatic arthritis is an inflammatory arthritis which affect people with psoriasis. It leads to pain and swelling in the joints, and often results in joint damage, deformities and reduced quality of life and function," explained Dr. Dafna Gladman, Professor of Medicine, University of Toronto and Senior Scientist, Schroeder Arthritis Institute, Krembil Research Institute. "While there are already approved medications for psoriatic arthritis, they do not work for all patients. Bimekizumab is a novel biologic medication which works very well for both psoriasis and psoriatic arthritis. It is exciting for both patients and health care providers that this medication is now added to the current treatment of psoriatic arthritis." "Axial spondyloarthritis is a chronic, painful, inflammatory disease involving the axial skeleton, which significantly impacts patients' mobility, function, and quality of life," said Dr. Proton Rahman, Distinguished Professor, Memorial University and Chief of Rheumatology, Newfoundland and Labrador Health Services. "Primary results from the two Phase 3 studies, BE MOBILE 1 and 2, have convincingly demonstrated that bimekizumab, a novel monoclonal antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, results in rapid improvement in axial spondyloarthritis symptoms. Bimekizumab marks a significant breakthrough in the management of axial spondyloarthritis and provides hope and relief for many living with this debilitating disease." BIMZLEX was previously approved for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy or phototherapy.1 About Psoriatic Arthritis Psoriatic arthritis (PsA) is both an autoimmune disease and a form of inflammatory arthritis. The immune systems of people with PsA attack the joints, in addition to the skin. It is estimated that 0.2 per cent of adults in Canada have PsA, but the exact numbers are unknown. PsA can develop at any age and up to a third (approximately 30 per cent) of people with psoriasis will develop PsA in their lifetime.5 About Axial Spondyloarthritis Axial spondyloarthritis (axSpA) is a chronic, progressive, painful form of inflammatory arthritis that causes significant and long-lasting pain in the lower back, buttocks and hips.6 axSpA can occur at any age, but typically begins between ages 20 and 40.7 Estimates suggest as many as one per cent of the Canadian adult population lives with a form of axSpA known as ankylosing spondylitis (AS).8 BIMZELX Clinical Program Health Canada's approval of BIMZELX for the treatment of adults living with active PsA was based on two multicentre, randomized, double-blind, placebo-controlled studies: BE OPTIMAL: evaluated 852 patients not previously exposed to any biologic disease-modifying anti-rheumatic drug (bDMARD-naïve) for the treatment of psoriasis or PsA2 BE COMPLETE: evaluated 400 patients with an inadequate response or intolerance to treatment with one or two tumour necrosis factor alpha inhibitors (TNFi-IR) for either psoriasis or PsA3 According to the results of both trials, bimekizumab treatment demonstrated positive outcomes at Week 16 vs placebo. The safety pro bimekizumab was consistent with previous Phase III studies in patients with plaque psoriasis, and with IL-17A inhibitors. In BE OPTIMAL, the most frequent treatment-emergent adverse events (TEAEs) (3 per cent or more) for patients on bimekizumab up to Week 16 were nasopharyngitis, upper respiratory tract infection, headache, diarrhoea, oral candidiasis, pharyngitis and hypertension.2 In BE COMPLETE, the most frequent TEAEs (2 per cent or more) for patients on bimekizumab up to Week 16 were nasopharyngitis, oral candidiasis and upper respiratory tract infection.3 Health Canada's approval of BIMZELX for the treatment of axSpA was based on two multicentre, randomised, double-blind, placebo-controlled studies: BE MOBILE 1: evaluated 254 patients with non-radiographic axSpA (nr-axSpA) BE MOBILE 2: evaluated 332 patients with ankylosing spondylitis (AS, also known as radiographic axSpA (r-axSpA))4 In both trials, dual inhibition of IL-17A and IL-17F with bimekizumab resulted in improvements in efficacy outcomes vs placebo and was well tolerated in patients with nr-axSpA and r-axSpA. The most frequently reported TEAEs (3 per cent or more in any bimekizumab group in either trial) up to Week 16 were nasopharyngitis, upper respiratory tract infection, pharyngitis, diarrhoea, headache and oral candidiasis.4 More information about BIMZELX can be found by accessing the product monograph.

Submission is supported by data from the Phase 3 QUASAR program, which showed a significantly greater percentage of patients with moderately to severely active ulcerative colitis who received TREMFYA® achieved clinical remission at Week 44 compared with placebo SPRING HOUSE, Pa., March 11, 2024 /PRNewswire/ -- Johnson & Johnson today announced the submission of a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking approval of TREMFYA® (guselkumab) for treatment of adults with moderately to severely active ulcerative colitis (UC). The submission is based on results from the Phase 3 QUASAR program evaluating the efficacy and safety of TREMFYA® in the treatment of individuals living with moderately to severely active UC who had an inadequate response or intolerance to conventional therapy, prior biologics and/or JAK inhibitors.1 The data show statistically significant and clinically meaningful improvements in symptoms, patient-reported outcomes such as fatigue and measures of disease activity including high bar endpoints such as endoscopic and histologic remission.2,3 The safety results were consistent with the known safety profile of TREMFYA® in approved indications.2,3,a "Despite advances in therapy, many people living with ulcerative colitis still experience inadequate response to or do not tolerate existing therapies," said David Lee, MD, PhD, Global Therapeutic Area Head Immunology. "TREMFYA has the potential to be a new treatment option for patients. We look forward to working with the FDA in review of this application and remain focused on developing new therapies for those living with chronic autoimmune conditions, such as ulcerative colitis, who are experiencing persistent and debilitating symptoms." TREMFYA® is a dual-acting IL-23i that blocks IL-23 and binds to CD64, a receptor on cells that produce IL-23.4 IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including UC.5 TREMFYA® was first approved in the U.S. in July 2017 for the treatment of adult patients with moderate-to-severe plaque psoriasis and was subsequently also approved for adults with active psoriatic arthritis in July, 2020.4 Clinical data from the Phase 3 QUASAR induction study through 12 weeks were presented at the 2023 Digestive Disease Week (DDW) Annual Meeting2 and results from the Phase 3 QUASAR maintenance study through 44 weeks will be presented at an upcoming medical meeting. Editor's Notes: a. TREMFYA® is not approved to treat UC. ABOUT THE QUASAR STUDY ( NCT04033445 ) QUASAR is a randomized, double-blind, placebo-controlled, parallel group, multicenter, seamless Phase 2b/3 program designed to evaluate the efficacy and safety of TREMFYA®, a selective IL-23 inhibitor, in adult patients with moderately to severely active ulcerative colitis who had an inadequate response or intolerance to conventional therapy (e.g., thiopurines or corticosteroids), prior biologics and/or JAK inhibitors (i.e., tumor necrosis factor-alpha antagonists, vedolizumab, or tofacitinib).1 QUASAR included a Phase 2b dose-ranging induction study, a confirmatory Phase 3 induction study, and a Phase 3 maintenance study. Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points.1 ABOUT ULCERATIVE COLITIS Ulcerative colitis (UC) is a chronic disease of the large intestine, also known as the colon, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers, that produce pus and mucus.6 It is the result of the immune system's overactive response.6 Symptoms vary, but may include loose and more urgent bowel movements, rectal bleeding or bloody stool, persistent diarrhea, abdominal pain, loss of appetite, weight loss and fatigue.6 ABOUT TREMFYA® (guselkumab) Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human, dual-acting monoclonal antibody that blocks IL-23 by binding to the p19 subunit of IL-23 and binding to CD64, a receptor on cells that produce IL-23.4 IL-23 is an important driver of the pathogenesis of inflammatory diseases.5 Findings for dual acting are limited to in vitro studies that demonstrate guselkumab binds to CD64, which is expressed on the surface of IL-23 producing cells in an inflammatory monocyte model. The clinical significance of this finding is not known.7,8,9,10 TREMFYA® is approved in the U.S.,4 Canada,11 Japan12 and a number of other countries for the treatment of adults with moderate to severe plaque psoriasis (PsO) who are candidates for injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light) and for the treatment of adult patients with active psoriatic arthritis ( PsA).4 It is also approved in the EU for the treatment of moderate to severe plaque PsO in adults who are candidates for systemic therapy and for the treatment of active PsA in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.13 Johnson & Johnson maintains exclusive worldwide marketing rights to TREMFYA®.

Dose ordered and robust HiSCRs were rapidly demonstrated with about a third of patients achieving HiSCR100, or resolution of abscesses and nodules, by week 16 and through week 32 Deep and consistent HiSCR responses were observed for placebo patients switching to active treatment Marked reductions in draining tunnels and skin pain also contributed to clinically meaningful improvements in quality of life Potential for differentiation was demonstrated with both high clinical responses as well as a favorable safety profile consistent with the IL-17A class and previous izokibep experience LOS ANGELES, March 11, 2024 (GLOBE NEWSWIRE) -- ACELYRIN, INC. (Nasdaq: SLRN), a late-stage clinical biopharma company focused on accelerating the development and delivery of transformative medicines in immunology, today announced long-term data from a Phase 2b clinical trial of izokibep in hidradenitis suppurativa (HS). These data demonstrated no evidence of increased safety liability with longer-term treatment and increased duration of therapy was associated with further clinical improvements over time. Patients who switched from placebo to izokibep at week 16 achieved a similar speed and magnitude of response as those who began treatment with izokibep at baseline for HiSCRs, draining tunnels, skin pain and Dermatology Life Quality Index (DLQI). High orders of HiSCR were achieved with the majority of patients achieving HiSCR75 and about a third achieving HiSCR100 by week 16 and through 32 weeks. These results are from an open label extension with all subjects through week 32. Additional information can be found at ACELYRIN.com. Further data from this trial will be presented at future scientific meetings. “The magnitude and depth of responses for signs and symptoms of Hidradenitis Suppurativa in this long-term study are consistent with izokibep’s mechanism of action. These results are corroborated by the appreciable clinical responses observed in the placebo cross-over cohort, which demonstrate rapid, HiSCR response,” said Kim Papp, MD, PhD, President and Director of Research, Probity Medical Research, Inc. “We believe that these consistent and robust results in HS point to the future potential for izokibep to deliver differentiated clinical benefits for patients.” “It’s heartening to see the exciting results from this longer term follow up across all of the important manifestations of this debilitating disease, despite the initial primary endpoint of this study not meeting statistical significance,” said Shao-Lee Lin, MD, PhD, Founder and CEO of ACELYRIN. “Across indications, we have observed clinically meaningful and potentially differentiated benefit from izokibep. We have consistently seen responses in high order efficacy measures such as HiSCR100 in HS and ACR70 and PASI100 in PsA, that move patients toward disease resolution. This reinforces our enthusiasm for developing izokibep as an important potential new medicine for patients.” Izokibep was well-tolerated with a favorable safety profile consistent with previous experience and the IL-17A class. Potential for differentiation was demonstrated with higher clinical responses achieved earlier than reported by other IL-17A agents and the IL-17A&F agents without evidence to date for increased risk of infection, especially fungal or suicidal ideation and behavior, in a patient population predisposed to infection and clinical depression. “The pain and discomfort that people living with HS experience on a daily basis is extremely debilitating,” said Falk Bechara, MD, Clinical Professor in the Department of Dermatology at the Ruhr-University Bochum. “These data are impressive, showing izokibep dose ordered, fast speed of onset across endpoints. The consistency and magnitude of responses in resolution of abscesses and nodules, reduction in draining tunnels, and improvement in pain, impact overall quality of life and suggest that izokibep could be a significant therapeutic for HS, with a positive benefit risk in addressing an unmet need.” Topline data from an ongoing phase 3 trial in HS is expected by the end of 2024. A confirmatory phase 3 trial of approximately 400 patients is planned to address guidance on size of safety database given the FDA no longer considers moderate-to-severe HS an orphan disease. About the Phase 2b Hidradenitis Suppurativa clinical trialThe Phase 2b clinical trial (NCT05355805) is a global, multi center, randomized double-blind, placebo-controlled, trial evaluating the safety and efficacy of izokibep dosed 160 mg every week (QW) or every two weeks (Q2W) versus placebo. At week 16, patients who received placebo were randomized to either the weekly or every two week active treatment arm and all patients were assessed through week 32. The objective of the study was to determine the effect of izokibep versus placebo on various measures of clinical impact and determine the appropriate dose(s) for further clinical development in hidradenitis suppurativa. For more information about the Phase 2b HS clinical trial, please visit www.clinicaltrials.gov. About Hidradenitis SuppurativaHidradenitis Suppurativa (HS) is a chronic Inflammatory skin disease causing scarring, abscesses, malodor and pain. HS typically occurs in areas with high concentrations of sweat glands and is typically accompanied by pain, malodor, drainage, and disfigurement that contribute to disability and a devastating impact on quality of life. Patients with HS miss a greater number of days of work and have increased disability compared to the average population. In 2019, there were an estimated 317,000 HS patients in the U.S., of which 50-60% were moderate-to-severe HS patients. About IzokibepIzokibep is a small protein therapeutic designed to inhibit IL-17A with high potency through tight binding affinity, the potential for robust tissue penetration due to its small molecular size, about one-tenth the size of a monoclonal antibody, and an albumin binding domain that extends half-life. Clinical trial data supports the hypothesis that these unique characteristics of izokibep may provide clinically meaningful and differentiated benefits for patients, including resolution of key manifestations of disease. Izokibep is being evaluated in multiple late-stage trials in moderate-to-severe hidradenitis suppurativa (HS), psoriatic arthritis (PsA), and uveitis, with plans to initiate an additional Phase 3 program in axial spondyloarthritis (AxSpA).
