People living with gMG often face treatment options tha= t are broad-acting, and that have traditionally only offered symptomatic re= lief=E2=80=9D , explained Professor Vera Bril, Professor of Medicine (Neuro= logy), University of Toronto, Director of the Neuromuscular Section, Divisi= on of Neurology, University of Toronto and University Health Network, Toron= to, and lead investigator of the MycarinG study.=E2=80=9CThere is a signifi= cant need for new, innovative treatment options to reduce the day-to-day bu= rden of gMG. Rozanolixizumab-noli is a new treatment option, targeting one = of the mechanisms of disease to provide symptom improvement in patient-and = physician reported outcomes at day 43.=E2=80=9D gMG is a rare, chronic, heterogeneous (phenotypic and pathogenic), unpredic= table autoimmune disease characterized by dysfunction and damage at the neu= romuscular junction (NMJ).^4,5,6 Several factors are understood to be drive= rs of gMG disease pathology, including complement-cascade, immune cells and= pathogenic IgG autoantibodies. Pathogenic IgG autoantibodies can impair sy= naptic transmission at the NMJ by targeting specific proteins on the post-s= ynaptic membrane^4,7=C2=A0This disrupts the ability of the nerves to stimul= ate the muscle and results in a weaker contraction.^4 gMG has a global prev= alence of 100=E2=80=93350 cases per every 1 million people.^5 =E2=80=9CNo two people living with gMG experience the disease in the same w= ay, so we can=E2=80=99t take a =E2=80=98one size fits all=E2=80=99 approach= to disease management,=E2=80=9D said Iris Loew-Friedrich, Executive Vice-P= resident and Chief Medical Officer at UCB. =E2=80=9CDisease management shou= ld be based on the clinical needs and preferences of the individual patient= , and the aim of treatment is to help restore that patient=E2=80=99s abilit= y to carry out activities of daily living. The approval of rozanolixizumab-= noli means doctors have an additional approved treatment option for their g= MG patients who have not yet found a treatment that meets their needs.=E2= =80=9D The FDA approval^1 is supported by safety and efficacy data from the pivota= l Phase 3 MycarinG study (NCT03971422), published in The Lancet Neurology i= n May 2023.^1 The primary efficacy endpoint was the comparison of the chang= e from baseline between treatment groups in the MG-ADL total score at day 4= 3. MG-ADL is a measurement tool which assesses the impact of gMG on daily f= unctions of 8 signs or symptoms that are typically affected in gMG. These i= nclude activities such as breathing, talking, swallowing, and being able to= rise from a chair^3. Each item is assessed on a 4-point scale where a scor= e of 0 represents normal function and a score of 3 represents loss of abili= ty to perform that function. A total score ranges from 0 to 24, with the hi= gher scores indicating more impairment. A statistically significant differe= nce favoring rozanolixizumab-noli was observed in the MG-ADL total score ch= ange from baseline [-3.4 points in rozanolixizumab-noli-treated group at ei= ther dose vs -0.8 points in the placebo-treated group (p<0.001)].=C2=A0 The secondary endpoint was the change between treatment groups from baselin= e to day 43 in the QMG. The QMG is a 13-item categorical grading system tha= t assesses muscle weakness. Each item is assessed on a 4-point scale where = a score of 0 represents no weakness and a score of 3 represents severe weak= ness. A total possible score ranges from 0 to 39, where higher scores indic= ate more severe impairment. A statistically significant difference favoring= rozanolixizumab-noli was observed in the QMG total score change from basel= ine [-5.4 points and -6.7 points in rozanolixizumab-noli-treated group at = =E2=89=887mg/kg and =E2=89=8810 mg/kg dose level, respectively, vs -1.9 poi= nts in the placebo-treated group (p<0.001)].=C2=A0 The most common adverse reactions (reported in at least 10% of patients tre= ated with in rozanolixizumab-noli) were headache, infections, diarrhea, pyr= exia, hypersensitivity reactions, and nausea.^1 =E2=80=9CWe want to thank UCB for their continued commitment to the MG comm= unity to bring a new FDA-approved treatment option for generalized myasthen= ia gravis to patients and their treating physicians,=E2=80=9D said Samantha= Masterson, President and Chief Executive Officer of the Myasthenia Gravis = Foundation of America (MGFA). =E2=80=9CPeople living with generalized myast= henia gravis continue to experience significant unmet medical needs, this m= eans expanding the number of FDA-approved treatment options is particularly= important to treat this chronic, autoimmune, neuromuscular disease.=E2=80= =9D Rozanolixizumab-noli will be commercially available in the U.S. during the = 3rd quarter of 2023. =C2=A0 =E2=80=9CBuilding on our decades of experience in neurology and immunology,= we are proud to support the MG community with solutions to help improve pa= tient lives, including a new FDA-approved treatment, education and support= =E2=80=9D, continued Iris Loew-Friedrich. The approval following priority r= eview of rozanolixizumab-noli is a testament to this medicine=E2=80=99s pot= ential as a generally well-tolerated treatment option that is targeted to t= he individual needs of patients. We are so grateful to the patients, care p= artners, and investigators who participated in the MycarinG study, and to o= ur employees and collaborators, whose dedication and commitment to the MG c= ommunity made this important milestone possible.=E2=80=9D The FDA reviewed rozanolixizumab-noli under Priority Review. Rozanolixizuma= b is also currently under review by the European Medicines Agency (EMA) and= the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) for the tre= atment of adults with gMG. In 2019, the U.S. FDA granted orphan drug design= ation to rozanolixizumab-noli for the treatment of generalized myasthenia g= ravis.^8 Orphan designation was granted by the European Commission in April= 2020 to rozanolixizumab for the treatment of generalized myasthenia gravis= .^9 The PMDA granted similar orphan status to rozanolixizumab in Japan in N= ovember.^10=C2=A0Responses from regulatory agencies to these submissions ar= e expected by H1 2024. =C2=A0 About Generalized Myasthenia Gravis (gMG) gMG is a rare disease with a global prevalence of 100=E2=80=93350 cases per= every 1 million people.^5 People living with gMG can experience a variety = of symptoms, including severe muscular weakness that can result in life-thr= eatening weakness of the muscles of respiration, double vision, drooping ey= elids, and difficulty swallowing, chewing and talking.^11,12 In gMG, pathogenic autoantibodies can impair synaptic transmission at the n= euromuscular junction (NMJ) by targeting specific proteins on the post-syna= ptic membrane.^3,4 This disrupts the ability of the nerves to stimulate the= muscle and results in a weaker contraction. gMG can occur in any race, gen= der or age.^13=C2=A0=C2=A0 About the MycarinG study^2 The MycarinG study (NCT03971422) is a multi-center, Phase 3, randomized, do= uble-blind, placebo-controlled study evaluating the efficacy and safety of = rozanolixizumab in adult patients with gMG, with an open-label extension. The primary endpoint for the MycarinG study is change in the Myasthenia Gra= vis-Activities of Daily Living Profile (MG-ADL) score, an eight-item patien= t-reported scale developed to assess MG symptoms and their effects on daily= activities. Additional endpoints include response rates, changes in the My= asthenia Gravis composite (MGC) score, the Quantitative MG (QMG) score, pat= ient-reported outcomes at day 43 and adverse events (AEs). The majority of = patients taking part in the MycarinG study opted to enroll in any future ex= tensions to this clinical trial. As a result, UCB is exploring the potentia= l for further extension studies into this treatment. For more information about the trial, visit https://clinicaltrials.gov/ct2/= show/NCT03971422.=C2=A0 About rozanolixizumab Rozanolixizumab is a subcutaneous administered, humanized monoclonal antibo= dy that specifically binds, with high affinity, to human neonatal Fc recept= or (FcRn). It has been designed to block the interaction of FcRn and Immuno= globulin G (IgG), accelerating the catabolism of antibodies and reducing th= e concentration of pathogenic IgG autoantibodies.^2=C2=A0 Outside of the U.S. rozanolixizumab is not approved for use in any indicati= on by any other regulatory authority worldwide. *In the U.S., the International Nonproprietary Name (INN) for rozanolixizum= ab is =E2=80=98rozanolixizumab-noli=E2=80=99 following the FDA=E2=80=99s = =E2=80=98Non-proprietary Naming of Biological Products Guidance=E2=80=99. T= his guidance advises that the nonproprietary name designated for originator= biological products should be a proper name that is a combination of the c= ore name and a distinguishing suffix that is devoid of meaning and composed= of four lowercase letters.=C2=A0 Important Safety Information for RYSTIGGO^=C2=AE WARNINGS AND PRECAUTIONS=C2=A0 Infections: RYSTIGGO may increase the risk of infection. Delay RYSTIGGO adm= inistration in patients with an active infection until the infection is res= olved. During treatment with RYSTIGGO, monitor for clinical signs and sympt= oms of infection. If serious infection occurs, administer appropriate treat= ment and consider withholding RYSTIGGO until the infection has resolved. Immunization Immunization with vaccines during RYSTIGGO treatment has not been studied. = The safety of immunization with live or live-attenuated vaccines and the re= sponse to immunization with any vaccine are unknown. Because RYSTIGGO cause= s a reduction in IgG levels, vaccination with live-attenuated or live vacci= nes is not recommended during treatment with RYSTIGGO. Evaluate the need to= administer age-appropriate vaccines according to immunization guidelines b= efore initiation of a new treatment cycle with RYSTIGGO. Aseptic Meningitis: Serious adverse reactions of aseptic meningitis (also c= alled drug-induced aseptic meningitis) have been reported in patients treat= ed with RYSTIGGO. If symptoms consistent with aseptic meningitis develop, d= iagnostic workup and treatment should be initiated according to the standar= d of care. Hypersensitivity Reactions: Hypersensitivity reactions, including angioedem= a and rash, were observed in patients treated with RYSTIGGO. Management of = hypersensitivity reactions depends on the type and severity of the reaction= . Monitor patients during treatment with RYSTIGGO and for 15 minutes after = for clinical signs and symptoms of hypersensitivity reactions. If a reactio= n occurs, institute appropriate measures if needed. ADVERSE REACTIONS In a placebo-controlled study, the most common adverse reactions (reported = in at least 10% of RYSTIGGO-treated patients) were headache, infections, di= arrhea, pyrexia, hypersensitivity reactions, and nausea. Serious infections= were reported in 4% of patients treated with RYSTIGGO. Three fatal cases o= f pneumonia were identified, caused by COVID-19 infection in two patients a= nd an unknown pathogen in one patient. Six cases of infections led to disco= ntinuation of RYSTIGGO.
