  • Rozanolixizumab-noli (Rystiggo) is indicated for the treatment of generalized myasthenia gravis in adult patients who are either acetylcholine receptor or muscle-specific tyrosine kinase antibody-positive.
  • Information about Rystiggo was derived from a single study, which was a randomized controlled trial named MycarinG.
  • This trial involved adults aged 18 years and above with AChR or MuSK autoantibody-positive generalized myasthenia gravis. It compared the effects of rozanolixizumab at doses of 7 mg/kg and 10 mg/kg with placebo.
  • In terms of efficacy, rozanolixizumab demonstrated clinically meaningful improvements in MG-ADL scores from baseline to day 43, indicating better outcomes in symptom control relative to placebo. Both the 7 mg/kg and 10 mg/kg doses showed significant improvement.
  • Regarding safety profile, treatment-emergent adverse events were observed more frequently among participants receiving rozanolixizumab than those receiving placebo. However, significant adverse events occurred at similar rates across all groups without any reported deaths during the study period.
  • Although there's no specific comparative data on safety and efficacy with other treatments within this study for direct comparison against other options for treating generalized myasthenia gravis; however, considering conventional therapy limitations such as increased infection risk & inadequate symptom control - Rystiggo presents itself as a potentially valuable addition due to its novel mechanism through neonatal Fc receptor inhibition.
