PANORAMA: Neuromuscular Organoids for Refractory AChR+ Myasthenia Gravis

Myasthenia gravis (MG) is an autoimmune disease in which autoantibodies attack the neuromuscular junction, the site at which nerve cells communicate with muscle fibres, impairing signal transmission and causing fluctuating muscle weakness that worsens with sustained activity. In most patients this dysfunction is reversible and improves with treatments that suppress the immune response. About 10 to 15 percent of patients do not respond adequately to standard therapy, and the mechanisms of this refractory course remain unclear. The study is based on the hypothesis that in refractory patients the autoantibody attack causes irreversible damage to the neuromuscular junction, and that this damage sustains symptoms despite appropriate treatment. A further aim is to identify circulating biomarkers reflecting such damage that may help predict response to therapy. The study includes adults with generalised MG positive for antibodies against the acetylcholine receptor, stratified by disease duration and treatment response into treatment-naive, treatment-sensitive and treatment-refractory MG. Subjects without neuromuscular disease and negative for these antibodies serve as controls. Blood samples (serum, plasma and mononuclear cells) are obtained from material left over from blood draws performed as part of routine care, together with clinical data including disease duration, symptom severity measured with validated scales (MG-ADL and QMG), antibody titre and treatment history.
