Official title

A Phase 3, Randomized, Open-Label, Parallel-Group Study to Compare the Pharmacodynamics, Pharmacokinetics, Efficacy, Safety, Tolerability, and Immunogenicity of Multiple Subcutaneous Injections of Efgartigimod PH20 SC With Multiple Intravenous Infusions of Efgartigimod in Patients With Generalized Myasthenia Gravis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to investigate the Pharmacodynamics (PD), Pharmacokinetics (PK), safety, tolerability, immunogenicity, and clinical efficacy of efgartigimod coformulated with recombinant human hyaluronidase PH20 (rHuPH20) as compared to efgartigimod IV infused in patients with generalized myasthenia gravis (gMG). The study duration is approximately 12 weeks. After screening, patients will be randomized to receive either efgartigimod infusions or efgartigimod PH20 subcutaneously (SC)
