It is the only once-daily = gMG target therapy for self-administration by adult patients with anti-AChR= antibody-positive gMG.=C2=A0 As a complement C5 inhibitor, zilucoplan inhibits complement-mediated damag= e to the neuromuscular junction through its targeted mechanism of action.^2= Benefits of self-administered treatment compared with=C2=A0intravenously a= dministered treatments can include reduced traveling time to and from hospi= tals, decreased interference with work obligations, and increased independe= nce. Unlike monoclonal antibody C5 inhibitors, as a peptide, zilucoplan can= be used concomitantly with intravenous immunoglobulin and plasma exchange,= without the need for supplemental dosing.^2=C2=A0 The FDA approval of zilucoplan^1 is supported by safety and efficacy data f= rom the RAISE study (NCT04115293), published in The Lancet Neurology in May= 2023.2 The RAISE study was a multi-center, phase 3, randomized, double-bli= nd, placebo-controlled study to assess the efficacy, safety profile, and to= lerability of zilucoplan in adult patients with anti-acetylcholine receptor= (AChR) antibody-positive gMG. Patients were randomized in a 1:1 ratio to r= eceive daily subcutaneous (SC) injections of 0.3 mg/kg zilucoplan or placeb= o for 12 weeks. The study demonstrated that zilucoplan delivered rapid, con= sistent, and statistically significant benefits in different patient-and-cl= inician reported outcomes at week 12 in a broad population of adult patient= s with mild-to-severe anti-AChR-antibody positive gMG. The most common adve= rse reactions (=E2=89=A510%) in patients with gMG were injection site react= ions, upper respiratory tract infection, and diarrhea. =E2=80=9CFor people with gMG, the unpredictable nature of the severity and = frequency of symptoms can be debilitating and can have a substantial impact= on many aspects of their day-to-day lives. In addition to muscle weakness,= people living with gMG experience fatigue, affecting their overall quality= of life,=E2=80=9D said James F. Howard, MD, Distinguished Professor of Neu= romuscular Disease, Professor of Neurology, Medicine and Allied Health, The= University of North Carolina at Chapel Hill School of Medicine and lead in= vestigator in the RAISE trial. =E2=80=9CZilucoplan demonstrated rapid impro= vements in gMG symptoms at Week 12, with differences seen as early as one w= eek, and provides a new treatment option for a broad population of AChR ant= ibody-positive gMG patients. Zilucoplan is designed for continued daily use= .=E2=80=9D gMG is a rare, chronic, heterogeneous, unpredictable autoimmune disease cha= racterized by dysfunction and damage at the neuromuscular junction (NMJ).^4= ,5,6 Several factors are understood to be drivers of gMG disease pathology,= including the complement cascade, immune cells and pathogenic Immunoglobul= in G (IgG) autoantibodies.^7 In anti-AChR antibody-positive gMG, pathogenic AChR autoantibodies (IgG1 an= d IgG3) initiate the classical complement pathway, leading to the cleavage = of C5 and the MAC (membrane attack complex) formation, damage to the NMJ, l= oss of AChRs and subsequent impaired synaptic transmission.^6,8,9 Preventin= g MAC formation reduces damage to the post-synaptic membrane, reduces disru= ption of ionic channel conductance and helps to preserve neuromuscular tran= smission.^8 MG has a global prevalence of 100=E2=80=93350 cases per every 1= million people.^5 =E2=80=9CThis is an important development for the community because, with m= ore FDA-approved treatments for generalized myasthenia gravis, physicians h= ave additional tools to treat this disease in individualized ways that are = the right fit for each individual patient,=E2=80=9D said Samantha Masterson= , President and Chief Executive Officer of the Myasthenia Gravis Foundation= of America. =E2=80=9CWe are so grateful to UCB for being part of the myast= henia gravis community and their continued commitment to finding solutions = for people living with this chronic, autoimmune, neuromuscular disease.=E2= =80=9D With the approval of zilucoplan, alongside the company=E2=80=99s neonatal F= c receptor (FcRn) blocker RYSTIGGO^=C2=AE (rozanolixizumab-noli), which was= approved earlier this year by the FDA under Priority Review designation fo= r the treatment of generalized myasthenia gravis (gMG) in adult patients wh= o are anti-acetylcholine receptor (AChR) or anti-muscle-specific tyrosine k= inase (MuSK) antibody-positive, UCB's portfolio provides healthcare profess= ionals the option of addressing either complement activation or pathogenic = auto-antibodies for appropriate patients.^3,10 =E2=80=9CWith the FDA approval for zilucoplan, we are very proud and excite= d to expand our support to the gMG community. Following the FDA approval an= d strong momentum with our FcRn inhibitor rozanolixizumab-noli and with our= tailored patient support services and commitment to widespread access, I a= m confident that UCB is the only company with a portfolio of two targeted t= herapies with different mechanisms of action and the experience to deliver = truly individualized transformational patient value to people living with t= his often debilitating rare disease=E2=80=9D said Jean-Christophe Tellier, = CEO, UCB. =E2=80=9CWe would like to extend our thanks to the patients, care= partners, and investigators who participated in the RAISE study, and to ou= r employees and collaborators, whose dedication and commitment to the gMG c= ommunity made this important milestone possible.=E2=80=9D The primary endpoint for the RAISE study was change from baseline to Week 1= 2 in the Myasthenia Gravis-Activities of Daily Living (MG-ADL) score. The M= G-ADL is an eight-item patient-reported outcome measure assessing MG sympto= ms and functional activities related to activities of daily living.^11 Thes= e include activities such as breathing, talking, swallowing, and being able= to rise from a chair.^12 Each of the items is scored, from 0 (normal) to 3= (most severe), providing a total MG-ADL score ranging from 0 to 24, where = higher scores indicate greater severity of symptoms.^2=C2=A0 The efficacy of zilucoplan was also measured, as a secondary endpoint, usin= g the Quantitative Myasthenia Gravis (QMG) total score which is a 13-item c= ategorical grading system that assesses muscle weakness. Each item is asses= sed on a 4-point scale where a score of 0 represents no weakness and a scor= e of 3 represents severe weakness. A total possible score ranges from 0 to = 39, where higher scores indicate more severe impairment.^11=C2=A0 At week 12, treatment with zilucoplan demonstrated a statistically signific= ant improvement from baseline compared to placebo for MG-ADL total score an= d QMG total score. Other secondary endpoints included the proportion of pat= ients with improvements of at least 3 and 5 points in the MG-ADL total scor= e and QMG total score, respectively, at week 12 without rescue therapy.^2 =E2=80=9CUntil now, people living with gMG have only had access to C5 thera= py intravenously, which can be inconvenient and time consuming. Now, with t= he option of zilucoplan, a self-administered once-daily, subcutaneous targe= ted complement C5 inhibitor, we hope a broad population of mild-to-severe a= dult patients with AChR-antibody-positive gMG will be able to have greater = independence=E2=80=9D said Iris Loew-Friedrich, Executive Vice-President an= d Chief Medical Officer at UCB. =E2=80=9CAlongside our FcRn blocker rozanol= ixizumab-noli, which was approved and launched in the U.S. earlier this sum= mer, our unique portfolio will support patients and healthcare professional= s to tailor choice of treatment according to their individual needs.=E2=80= =9D=C2=A0 About zilucoplan Zilucoplan is a once-daily, SC, self-administered peptide inhibitor of comp= lement component 5 (C5 inhibitor). As the only once-daily gMG target therap= y for self-administration by adult patients with anti-AChR antibody-positiv= e gMG, zilucoplan inhibits complement-mediated damage to the neuromuscular = junction through its targeted mechanism of action.^2=C2=A0 In September 2023, the Committee for Medicinal Products for Human Use (CHMP= ) of the European Medicines Agency (EMA) issued a positive opinion recommen= ding granting marketing authorization for zilucoplan in the European Union = (EU) as an add-on to standard therapy for the treatment of generalized myas= thenia gravis (gMG) in adult patients who are anti acetylcholine receptor (= AChR) antibody-positive.^13 A final decision on approval in the EU is expec= ted before the end of the year, in line with the EMA=E2=80=99s standard rev= iew timeline.=C2=A0 Also in September 2023, the Japanese Ministry of Health, Labour and Welfare= (MHLW) approved zilucoplan for the treatment of gMG in adult patients who = inadequately respond to steroids or other immunosuppressants.^14=C2=A0 Zilucoplan is currently under review by the Australian Therapeutic Goods Ad= ministration (TGA) and Health Canada for the treatment of adults with gMG. = Responses from regulatory agencies to these submissions are expected betwee= n H2 2023 and H2 2024.=C2=A0 Orphan designation was granted by the FDA in 2019 to zilucoplan for the tre= atment of myasthenia gravis.^14 About generalized Myasthenia Gravis (gMG) gMG is a rare autoimmune disease with a global prevalence of 100=E2=80=9335= 0 cases per every 1 million people.5 People living with gMG can experience = a variety of symptoms, including severe muscular weakness that can result i= n double vision, drooping eyelids, difficulty with swallowing, chewing and = talking, as well as life-threatening weakness of the muscles of respiration= .^4,16 In MG, pathogenic autoantibodies can impair synaptic transmission at the ne= uromuscular junction (NMJ) by targeting specific proteins on the post-synap= tic membrane.^17 This disrupts the ability of the nerves to stimulate the m= uscle and results in a weaker contraction. gMG can occur in any race, gende= r or age.^4,16 About the RAISE study^2 The primary endpoint for the RAISE study was change from baseline to Week 1= 2 in the Myasthenia Gravis-Activities of Daily Living (MG-ADL) score.=C2=A0 Secondary endpoints included change from baseline in the Quantitative Myast= henia Gravis (QMG) score, the Myasthenia Gravis Composite (MGC) and the Mya= sthenia Gravis Quality of Life 15 revised (MG-QoL15r) score from baseline t= o Week 12. Other secondary efficacy outcomes, time to first receipt of resc= ue therapy over 12 weeks, the proportion of patients with minimal symptom e= xpression (MSE) (defined as MG-ADL of 0 or 1 without rescue therapy), the p= roportion of patients with a =E2=89=A53-point reduction in MG-ADL without r= escue therapy and the proportion of patients with a =E2=89=A55-point reduct= ion in QMG without rescue therapy, all measured at Week 12.=C2=A0 Safety was assessed by the incidence of treatment-emergent adverse events (= TEAEs).=C2=A0 Patients who completed the RAISE trial had the possibility to enter the ope= n-label extension study, RAISE-XT (NCT04225871).^2=C2=A0 For more information about the trial, visit https://clinicaltrials.gov/ct2/= show/NCT04115293.=C2=A0 About rozanolixizumab-noli In addition to zilucoplan, UCB=E2=80=99s gMG portfolio includes the FDA-app= roved medicine =C2=A0RYSTIGGO=C2=AE (rozanolixizumab-noli), a subcutaneousl= y infused monoclonal antibody targeting the neonatal Fc receptor (FcRn).^9= =C2=A0 In June 2023, rozanolixizumab-noli was approved by the FDA, for the treatme= nt of gMG in adult patients who are anti-acetylcholine receptor (AChR) or a= nti-muscle-specific tyrosine kinase (MuSK) antibody-positive, having been g= ranted Priority Review for its Biologic License Application (BLA).^3,10=C2= =A0 In September 2023, rozanolixizumab was approved by the Japanese Ministry of= Health, Labour and Welfare (MHLW) for the treatment of gMG in adult patien= ts who inadequately respond to steroids or other immunosuppressants.^14=C2= =A0 Rozanolixizumab is currently under review by the European Medicines Agency = (EMA), the Australian Therapeutic Goods Administration (TGA) and Health Can= ada for the treatment of adults with gMG.
