Myasthaenia Gravis

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.

The purpose of this long-term follow-up (LTFU) study is to collect delayed adverse events (AEs) and understand the persistence of KYV-101 (autologous CAR T cell product; gene-modified product), in participants who have been administered KYV-101 (gene-modified product; autologous CAR T cell product). This LTFU protocol will be open to any participant who received at least one infusion of KYV-101 in a previous Kyverna sponsored clinical trial or Investigator Initiated Trial (IIT).

This study is an open label, single center, prospective, 26 weeks study with descriptive analysis where IVIG is replaced by efgartigimod therapy. MG-ADL and MGQOL evaluations will occur weekly throughout the study to week 26.

MEK inhibitors (trametinib, cobimetinib, selumetinib or binimetinib) have been used since 2016 to treat metastatic melanoma, by targeting the MAPK pathway Neuromuscular complications (neuropathy, myasthenia or myositis) have been reported in patients treated with MEK inhibitors. With the growing use of these new oncology therapies, neurologists, oncologists and other clinicians are likely to be increasingly confronted with MEK inhibitor-induced neuropathy, myasthenia or myositis. Yet, so far, these complications have only been documented in a few single case reports. Our aim was to characterize the neuromuscular complications associated with MEK inhibitors used either alone or in combination.

The goal of this clinical trial is to evaluating the efficacy and safety of Blinatumomab in the treatment of refractory myasthenia gravis and exploring the immunological mechanisms of Blinatumomab therapy in refractory myasthenia gravis. The main questions it aims to answer are: Will Blinatumomab improve the symptoms of participants? What medical problems do participants have when using Blinatumomab? Participants will: Continuous intravenous infusion of Blinatumomab for 5 days, pause for one week, and continue continuous intravenous infusion for 5 days Visit the clinic once every 1 month for checkups and tests Keep a diary of their symptoms

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.
