Bimekizumab

BRUSSELS, Belgium I November 20, 2024 I UCB, a global biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has approved BIMZELX ® (bimekizumab-bkzx) for the treatment of adults with moderate to severe hidradenitis suppurativa (HS). 1 Bimekizumab-bkzx is the first and only approved medicine designed to selectively inhibit interleukin 17F (IL-17F) in addition to interleukin 17A (IL-17A). 1 “The approval of BIMZELX in moderate to severe hidradenitis suppurativa is welcome given the substantial unmet clinical needs and limited number of treatment options available today,” said investigator and lead author of the studies, Alexa B. Kimball, MD, MPH, Beth Israel Deaconess Medical Center and Professor of Dermatology, Harvard Medical School, Boston, MA, U.S. “In the Phase 3 clinical studies, patients treated with bimekizumab-bkzx achieved deep and sustained clinical responses up to 48 weeks.” Hidradenitis suppurativa is a chronic, recurring, painful and potentially debilitating inflammatory skin disease. 2,3 The main symptoms are nodules, abscesses and pus-discharging fistulas, i.e., channels leading out of the skin, typically in the armpits, groin and buttocks. 2,3 People with HS experience flare-ups of the disease as well as severe pain, which can have a major impact on quality of life. 2,3 “We are working toward a world where people with hidradenitis suppurativa live without stigma, feel widely understood and are treated effectively. Today’s approval of bimekizumab-bkzx is an exciting time for the hidradenitis suppurativa community, offering a new possibility for the treatment of people in the U.S. living with moderate to severe disease,” said Brindley Brooks, Founder and Executive Director, HS Connect, U.S. The approval is supported by data from two Phase 3 studies, BE HEARD I and BE HEARD II, which evaluated the efficacy and safety of bimekizumab-bkzx in the treatment of adults with moderate to severe HS. 4 Results showed that a higher proportion of patients treated with bimekizumab-bkzx vs. placebo achieved a 50 percent or greater improvement in HS signs and symptoms at Week 16, as measured by HiSCR50, the primary endpoint in both trials. 4 Bimekizumab-bkzx treatment also resulted in clinically meaningful improvements in the key ranked secondary endpoint, HiSCR75, vs. placebo at Week 16. 4 Clinical responses were sustained to Week 48. 4 The safety profile of bimekizumab-bkzx was consistent with safety data seen in previous trials across indications with no new safety signals. 4 Detailed results from BE HEARD I and BE HEARD II have been published in The Lancet . 4 “We are thrilled that with this milestone BIMZELX is now FDA-approved for the treatment of adults with moderate to severe hidradenitis suppurativa, a chronic and painful disease affecting approximately one in 100 people. This is the fifth patient population who may benefit from BIMZELX in the U.S., representing a significant step forward in our mission to alleviate the global burden of immune-mediated inflammatory diseases,” said Emmanuel Caeymaex, Executive Vice President, Head of Patient Impact and Chief Commercial Officer, UCB. “This progress underscores our commitment to addressing unmet needs in hidradenitis suppurativa and other immunological conditions, delivering innovative medicines and raising standards of care.” This FDA approval of bimekizumab-bkzx for the treatment of adults with moderate to severe hidradenitis suppurativa follows its recent approvals for the treatment of adults with active psoriatic arthritis, adults with active non-radiographic axial spondyloarthritis with objective signs of inflammation and adults with active ankylosing spondylitis. 1 Bimekizumab-bkzx was first approved in the U.S. in October 2023, for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. 1 Notes to Editors: About BE HEARD I and BE HEARD II BE HEARD I and BE HEARD II are randomized, double-blind, placebo-controlled, parallel group, multicenter, Phase 3 studies designed to evaluate the efficacy and safety of bimekizumab-bkzx in adults with moderate to severe hidradenitis suppurativa (HS). 4 The two studies had a combined enrolment of 1,014 participants with a diagnosis of moderate to severe HS. 4 The primary endpoint in both studies was HiSCR50 at Week 16. 4 Secondary endpoints included HiSCR75 and HS-specific skin pain response at Week 16. 1,4 HiSCR50 and HiSCR75 are defined as at least either a 50 or 75 percent reduction from baseline in the total abscess and inflammatory nodule count, with no increase from baseline in abscess or draining tunnel count.4 Detailed results from these studies are published in The Lance t. 4 About BIMZELX® (bimekizumab-bkzx) in the U.S. Bimekizumab-bkzx is a humanized IgG1 monoclonal antibody that selectively binds to IL-17A, IL-17F and IL-17AF cytokines, blocking their interaction with the IL-17RA/IL-17RC receptor complex. 1 Please see Important Safety Information below and full U.S. Prescribing Information at http://www.ucb-usa.com/Innovation/Products/BIMZELX . BIMZELX U.S. IMPORTANT SAFETY INFORMATION 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 definitively 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, instruct 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, including serious 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.

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.
