Filter by:The purpose of this 4-period study is to confirm the efficacy and safety of batoclimab in participants with gMG. In Period 1, participants will be randomized 1:1:1 to receive batoclimab 680 milligrams (mg) subcutaneously (SC) once a week (QW) or 340 mg SC QW or placebo. The primary efficacy endpoint will be assessed by change in the myasthenia gravis activities of daily living (MG- ADL) score in acetylcholine receptor antibody seropositive (AChRAb+) participants. In Period 2, participants previously treated with batoclimab will be re-randomized to stay on batoclimab (340 mg SC QW or 340 mg SC every two weeks) or receive placebo treatment. The secondary endpoint of maintenance of efficacy will be assessed by change in the MG- ADL score in AChRAb+ participants. Participants demonstrating a response to batoclimab during either Period 1 or 2 may enter the long-term extension (Period 3). Participants who complete Period 3 are eligible to participate in Period 4 (Optional Long-Term extension) according to their treatment assignment in Period 3.
The purpose of this trial is to evaluate the long-term safety of efgartigimod IV and efgartigimod PH20 SC administered to participants with gMG in the antecedent studies, ARGX-113-2006 and ARGX-113-2207, respectively.
This study will evaluate the efficacy and safety of ALXN2050 (120 milligrams [mg], 180 mg) in participants with generalized myasthenia gravis (gMG). Safety will be monitored throughout the study.
The primary objective is: To evaluate the effect of pozelimab + cemdisiran on daily functioning that is impacted by signs and symptoms in patients with symptomatic generalized myasthenia gravis (gMG) The secondary objectives of the study are: - To evaluate the effect of pozelimab + cemdisiran (ie, combination) and cemdisiran monotherapy on: - Clinician-assessed signs of myasthenia gravis (MG) and muscle strength - Daily functioning that is impacted by signs and symptoms in patients with symptomatic gMG (cemdisiran monotherapy only). - Proportion of patients with improvements in daily function that is impacted by signs and symptoms of MG - Proportion of patients that have improvements in clinician-assessed signs of MG and muscle strength - Health related quality of life - Proportion of patients with minimal MG symptoms - Patient- and clinician-reported signs and symptoms of MG - To evaluate the safety and tolerability of pozelimab + cemdisiran and cemdisiran monotherapy - To assess the concentration of total pozelimab in serum - To assess the concentrations of cemdisiran and its metabolites in plasma - To assess the immunogenicity of pozelimab - To assess the concentration of total C5 in plasma - To assess the immunogenicity of cemdisiran - To study the effect of pozelimab + cemdisiran and cemdisiran monotherapy on complement activation
This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics (PD), immunogenicity, and efficacy of subcutaneous (SC) ALXN1830 in adults with generalized myasthenia gravis (gMG).
The purpose of this open-label study is to investigate the efficacy, safety, and tolerability of a continuous regimen of efgartigimod compared with a cyclic regimen in participants with Generalized Myasthenia Gravis (gMG). Study details include: The study duration will be up to 138 weeks (including screening and a safety follow-up of up to 9 weeks) - Part A (regimen comparison period) - 21 weeks - Part B (extension period) - up to 105 weeks The visit frequency, including virtual visits, will be weekly through Week 21 and every 5 weeks for the remainder of the study.
This study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of satralizumab compared with placebo in participants with generalized myasthenia gravis (gMG).
The purpose of this trial is to investigate the PK, PD, safety, and activity of efgartigimod IV in children and adolescents aged from 2 to less than 18 years of age with gMG. Trial details include: - The maximum trial duration for each individual participant will be approximately 28 weeks - The treatment duration will be 8 weeks for the dose-confirmatory part (Part A) and 18 weeks for the treatment response-confirmatory part (Part B)
The purpose of this study is to evaluate the long-term safety and tolerability of efgartigimod PH20 SC 1000 mg, and the clinical efficacy, PD, pharmacokinetics (PK), immunogenicity, impact on the quality of life (QoL) of the participants, treatment satisfaction, and administration method preference, and the feasibility of self- and caregiver-supported administration of the SC injection. Treatment duration: 3-week treatment periods, repeated as needed with at least 28 days in between treatment periods Health measurements: total levels of immunoglobulin G (IgG), Acetylcholine receptor binding autoantibodies (AChR-Ab) levels, Myasthenia Gravis Activities of Daly Living (MG-ADL).
This expanded access protocol applies to patients with gMG who are not enrolled in an ongoing clinical trial. The aim of the trial is to provide patients with generalized myasthenia gravis (gMG), who are ineligible to participate in a clinical trial, access to efgartigimod treatment before regulatory approval. There are country-specific protocols and also individual use EAP. Recruitment for the treatment protocol in US is now closed (ARGX-113-EAP-2101).
