A Study to Evaluate the Safety, PD, PK and Efficacy of ARGX-113 in Patients With Pemphigus

Summary

The proposed study is an open-label, non-controlled, adaptive-design Phase II study to evaluate the safety, pharmacodynamics, pharmacokinetics, efficacy, and conditions of use (dosage, frequency of administration at maintenance) of ARGX-113 in patients with mild to moderate Pemphigus (Vulgaris or Foliaceus), either newly diagnosed or relapsing. The total study duration for each patient is less than 6 months. It consists of a Screening period, an Induction, a maintenance treatment period followed by a treatment-free Follow-up (FU) period.
