This is a 26-week study to assess the efficacy, safety and tolerability of IMVT-1402 in adult participants with mild to severe generalized myasthenia gravis.
The main purpose of this study is to measure how well adults with new-onset gMG (which means they've had generalized disease signs and/or symptoms for less than 1 year) respond to treatment with efgartigimod PH20 SC. The study consists of a treatment period of 51 weeks. The study duration for each participant will be approximately 58 weeks.
This study expands and validates the pilot study NCT06381284. It is a fully remote, site-less, prospective, observational study enrolling adults in the United States (excluding U.S. territories) with undiagnosed neuromuscular symptoms. The primary objective is to determine the validity of a self-assessment tool in encouraging undiagnosed participants, recruited through a social media campaign, to seek medical evaluation for suspected myasthenia gravis (MG).
This study plans to learn more about if the drug efgartigimod can be used in the hospital to treat exacerbations in participants with myasthenia gravis (MG). Efgartigimod has been approved by the FDA for ongoing (chronic) treatment of generalized MG in adult patients who are anti-acetylcholine receptor (AChR) antibody positive but has not been studied in the treatment of worsening weakness requiring hospital admission (known as "exacerbation"). This investigation aims to see if using efgartigimod in this way improves symptoms and recovery from exacerbation, and how it affects certain MG markers in the blood. The main questions it aims to answer are: * Is efgartigimod effective as a hospital-administered acute therapy for participants with worsening MG (MG exacerbation) who require hospitalization? * Will efgartigimod lead to clinical improvement with a similar reduction in validated research scales, such as the Quantitative MG (QMG) scale, as standard of care therapies? Participants will receive 4 doses of efgartigimod over the course of 4 weeks with an additional follow-up visit at the clinic.
The AURORA Study is evaluating the safety, tolerability, and efficacy of an investigational mRNA CAR T-cell therapy known as Descartes-08 in adults with acetylcholine receptor autoantibody -positive generalized myasthenia gravis. Part 1 of the study will last around 6 months. For eligible participants, Part 2 will last around 8 months.
A study to evaluate the efficacy, safety and tolerability of Remibrutinib versus placebo in adult patients with Generalized Myasthenia Gravis who are on stable, standard-of-care (SOC) treatment.
This is a phase I/II study to assess safety, efficacy, and cellular kinetics of YTB323 in participants with treatment-resistant generalized myasthenia gravis. YTB323 is a Biological CAR-T cell therapy.
The goal of this observational study is to learn about the experiences of people living with Myasthenia Gravis (MG) in the United States. The main questions it aims to answer are: * How and when are people with MG diagnosed? * What are the most common symptoms associated with MG? * What treatments are being used to treat MG? * What are the impacts of MG on activities of daily living, employment and quality of life? * What are the experiences with exacerbation, hospitalization and healthcare access for people with MG? Participants will answer a survey to enroll in the study, and be invited to fill out an update survey twice a year.
The primary objective of this study is to assess the pharmacokinetics and pharmacodynamics of gefurulimab in pediatric participants with AChR+ gMG for the duration of the study.
The purpose of this study is to evaluate the efficacy and safety of efgartigimod PH20 SC given by a pre-filled syringe in adult patients with ocular myasthenia gravis. The study consists of a part A (approximately 7 weeks) and a part B (up to 2 years). In part A, half of the participants will receive efgartigimod PH20 SC and the other half will receive placebo. In part B, all participants will receive efgartigimod PH20 SC. The participants will be in the study for about up to 2 years and 12 weeks.
