Use of Biologics to Treat Relapsing and/or Refractory Eosinophilic Granulomatosis With Polyangiitis: Data From a European Collaborative Study

Our data suggest that 100 mg MEPO monthly could be an acceptable dosage for first-line therapy in selected instances of EGPA, recognizing, however, that this has not been compared to the validated dosage of 300 mg monthly.
