This acceptance follows the recent European Medicines Agency (EMA) validati= on of the Marketing Authorization Application (MAA) for zilucoplan for the = treatment of adult patients with AChR-Ab+ gMG and who require treatment in = addition to steroids or non-steroidal immunosuppressants. Validation confir= ms that the application is complete and the formal review process by the EM= A=E2=80=99s Committee for Medicinal Products for Human Use (CHMP) can begin= . Orphan designation was granted in 2022 by the European Commission to zilu= coplan for the treatment of myasthenia gravis.^2 gMG is a chronic and unpredictable auto-immune disease in which pathogenic = autoantibodies can impair synaptic transmission at the neuromuscular juncti= on by targeting specific proteins on the post-synaptic membrane. This disru= pts the ability of the nerves to stimulate the muscle and results in a weak= er contraction.^4 People living with MG can experience a variety of symptom= s, including drooping eyelids, double vision, and difficulty in swallowing,= chewing and talking, as well as severe muscle weakness that can result in = life-threatening weakness of the muscles of respiration.^3 In the U.S. the = prevalence of MG is estimated at 14 to 20 per 100,000 population; approxima= tely 36,000 to 60,000 cases.^4 In Europe, the prevalence is estimated at 10= per 100,000 population.^5 =E2=80=9CPeople living with gMG experience high treatment burden, on top of= the debilitating impact of the condition, and there is a clear need for ad= ditional targeted treatments to support the gMG community. Our goal is to p= rovide a solution that can help meet these needs and transform lives,=E2=80= =9D said Charl van Zyl, Executive Vice President Neurology Solutions & Head= of EU/International Markets, UCB. =E2=80=9CThe acceptance of the NDA by th= e FDA as well as the acceptance of the MAA by the EMA, brings us one step f= urther on our journey towards approval for this medicine. We look forward t= o working with the FDA and EMA to help bring this important new treatment o= ption to patients.=E2=80=9D The NDA and MAA are based on data from the pivotal Phase 3 RAISE study (NCT= 04115293), which demonstrated at week 12 that treatment with zilucoplan (0.= 3 mg/kg daily) resulted in clinically meaningful and statistically signific= ant improvements in key gMG-specific outcomes compared with placebo in pati= ents with AChR-Ab+ gMG. The study met its primary endpoint with zilucoplan = showing a placebo-corrected mean improvement of 2.09 points in the Myasthen= ia Gravis Activities of Daily Living (MG-ADL) score at week 12 (p<0.001).^6 Zilucoplan demonstrated a favorable safety and tolerability profile, showin= g a similar rate of treatment-emergent adverse events (TEAEs) between ziluc= oplan (76.7%) and placebo (70.5%). The most common TEAEs were injection sit= e bruising, headache, and diarrhea. Rates of treatment discontinuation due = to a TEAE were low and all patients who completed the 12-week treatment per= iod have entered the ongoing RAISE-XT open-label extension study (NCT042258= 71).^6,7 In the RAISE study, 174 adult patients were randomised to receive daily SC,= self-administered doses of placebo (N=3D88) or zilucoplan 0.3 mg/kg (N=3D8= 6). Patient demographics and baseline disease characteristics were generall= y balanced between treatment arms.^6 As a complement C5 inhibitor, zilucoplan is a targeted therapy that inhibit= s key components in the underlying pathophysiology of gMG, addressing the u= nderlying mechanism of neuromuscular junction damage.^8,9 =E2=80=9CWe are deeply committed to improving outcomes for the gMG communit= y. People who live with gMG suffer unpredictable, fluctuating, and debilita= ting symptoms, which have a huge impact on their lives. We want to help red= uce the day-to-day burden of this challenging disease,=E2=80=9D said Iris L= oew-Friedrich, Executive Vice-President and Chief Medical Officer at UCB. = =E2=80=9CIf approved, zilucoplan has the potential to address the unmet nee= d for people with gMG by providing targeted improvements in signs and sympt= oms of gMG disease activity and severity. A benefit of targeted treatment i= s that it may help reduce the adverse events that can be associated with no= n-specific immunosuppressive treatment of gMG.=E2=80=9D=C2=A0 UCB anticipates making regulatory filings for zilucoplan in gMG in Great Br= itain, Japan, and rest of the world from Q3 2022 onwards.=C2=A0 Alongside zilucoplan, UCB is also investigating rozanolixizumab, a SC-admin= istered, humanized monoclonal antibody that specifically binds, with high a= ffinity, to human neonatal Fc receptor (FcRn), as a potential treatment for= gMG. UCB anticipates filing regulatory submissions for rozanolixizumab lat= er this year.=C2=A0 For further information, contact UCB:=C2=A0 Brand Communications, Rare Diseases Jim Baxter T+32.2.473.78.85.01=C2=A0 jim.baxter@ucb.com=C2=A0 Corporate Communications, Media Relations Laurent Schots=C2=A0 T+32.2.559.92.64 =C2=A0 Laurent.schots@ucb.com=C2=A0 Investor Relations Antje Witte =C2=A0 =C2=A0 =C2=A0 =C2=A0=C2=A0 T +32.2.559.94.14=C2=A0 antje.witte@ucb.com About Generalized Myasthenia Gravis (gMG) Myasthenia gravis is a rare disease impacting more than 700,000 people worl= dwide.^11 People living with gMG can experience a variety of symptoms, incl= uding drooping eyelids, double vision, difficulty swallowing, chewing and t= alking, as well as severe muscular weakness that can result in life threate= ning weakness of the muscles of respiration.^3, 4 gMG is a chronic and unpredictable auto-immune disease in which pathogenic = autoantibodies can impair synaptic transmission at the neuromuscular juncti= on (NMJ) by targeting specific proteins on the post-synaptic membrane. This= disrupts the ability of the nerves to stimulate the muscle and results in = a weaker contraction.^4,12=C2=A0gMG can occur in any race, although previou= s studies have shown that women are more often impacted than men.^13,14=C2= =A0 Most patients with gMG have pathogenic IgG antibodies that disrupt the = transmission of nerve impulses to muscles in the NMJ and some activate the = complement cascade.^15=C2=A0 Complement-mediated destruction via MAC format= ion is a key mechanism causing damage at the NMJ and is the key driver of d= isease in AChR-Ab+ gMG. About the zilucoplan RAISE study ^6,7 The RAISE study (NCT04115293) is a multi-center, Phase 3, randomized, doubl= e-blind, placebo-controlled study to confirm the efficacy, safety, and tole= rability of zilucoplan in patients with AChR-Ab+ gMG. Patients were randomi= zed in a 1:1 ratio to receive daily subcutaneous (SC) doses of 0.3 mg/kg zi= lucoplan or placebo for 12 weeks. The primary endpoint for the RAISE study is change from baseline to Week 12= in the Myasthenia Gravis-Activities of Daily Living (MG-ADL) score. Second= ary endpoints include change in the Quantitative Myasthenia Gravis (QMG) sc= ore, the Myasthenia Gravis Composite (MGC) and the Myasthenia Gravis Qualit= y of Life 15 revised (MG-QoL15r) score from baseline to Week 12, =C2=A0time= to rescue therapy, the proportion with minimal symptom expression (MSE) (d= efined as MG-ADL of 0 or 1), the proportion with a =E2=89=A53-point reducti= on in MG-ADL and the proportion with a =E2=89=A55-point reduction in QMG wi= thout rescue therapy, all measured at Week 12. The secondary safety endpoin= t is incidence of TEAEs. Patients who completed the 12 week RAISE trial had= the possibility to enter the open label extension study, RAISE-XT.=C2=A0 For more information about the trial visit https://clinicaltrials.gov/ct2/s= how/NCT04115293.=C2=A0 About Zilucoplan=C2=A0 Zilucoplan is a once-daily SC, self-administered peptide inhibitor of compl= ement component 5 (C5 inhibitor) under clinical development by UCB in gMG. = As a C5 inhibitor, zilucoplan inhibits complement-mediated damage to the ne= uromuscular junction through its targeted dual mechanism of action.^9 In 20= 19, the US FDA granted orphan drug designation to zilucoplan for the treatm= ent of myasthenia gravis.^1 Orphan designation was granted in 2022 by the E= uropean Commission to zilucoplan for the treatment of myasthenia gravis.^2 The safety and efficacy of zilucoplan have not been established and it is n= ot currently approved for use in any indication by any regulatory authority= worldwide. About Rozanolixizumab Rozanolixizumab is an SC administered, humanized monoclonal antibody that s= pecifically binds, with high affinity, to human neonatal Fc receptor (FcRn)= . It has been designed to block the interaction of FcRn and Immunoglobulin = G (IgG), accelerating the catabolism of antibodies and reducing the concent= ration of pathogenic IgG autoantibodies.^16,15 Rozanolixizumab is under clinical development with the aim of improving the= lives of people with pathogenic IgG-autoantibody-driven autoimmune disease= s. In 2019, the US FDA granted orphan drug designation to rozanolixizumab f= or the treatment of myasthenia gravis.^17 Orphan designation was granted in= 2020^18 by the European Commission for rozanolixizumab to the treatment of= myasthenia gravis.
