Summary

Detailed description

The study aims to investigate the safety, tolerability, efficacy, pharmacodynamics (PD), pharmacokinetics (PK), and immunogenicity of efgartigimod compared to placebo in participants with post-COVID-19 postural orthostatic tachycardia syndrome (POTS) (post-COVID-19 POTS). Efgartigimod may be a viable treatment option for individuals diagnosed with post-COVID-19 POTS because it has been shown to reduce IgG levels, including IgG autoantibodies, which may underlie some of the autonomic disease manifestations in these patients.
