Pathogenic IgG autoantibodies play a crucial role in the pathogenesis of autoimmune diseases, and removal of pathogenic IgG autoantibodies is an important therapeutic approach and tool for such diseases. The neonatal Fc receptor (FcRn) interacts with IgG and protects it from lysosomal degradation. FcRn inhibitors accelerate the clearance of IgG antibodies, including pathogenic IgG autoantibodies, by targeting and blocking the binding of FcRn to IgG. Theoretically, FcRn inhibitors can be applied for the treatment of IgG-mediated autoimmune diseases. With successful completion of multiple relevant clinical trials, key evidence-based data have been provided for FcRn inhibitors in the treatment of IgG-mediated autoimmune diseases, and several FcRn inhibitors have been approved for these indications. Additional trials are being planned or conducted. This review examines all available high-quality clinical trials of FcRn inhibitors assessing IgG-mediated autoimmune diseases.

Downregulation of FcRn promotes ferroptosis in herpes simplex virus-1-induced lung injury.

Article Synopsis
- HSV-1 infection can lead to lung injury, and a study found that lower levels of FcRn (a protein) are linked to more severe lung damage caused by the virus.
- The study revealed that HSV-1 increases the methylation of the FcRn gene, which reduces its expression by promoting DNMT3b, a protein that inhibits transcription through a specific region of the FcRn promoter.
- Inhibiting ferroptosis (a type of cell death) with a drug helped reduce lung injury in cases affected by HSV-1, indicating that targeting FcRn might be a promising therapeutic approach.
Individualized Dosing of Efgartigimod in Patients With Generalized Myasthenia Gravis: Clinical Experience at a Single Center.

Introduction/aims: Neonatal Fc receptor (FcRn) inhibitors represent a promising treatment option for patients with generalized myasthenia gravis (gMG); however, data on clinical use are limited. The aim of this report is to describe one center's approach to efgartigimod dosing in patients with gMG.
Methods: Medical records of patients with acetylcholine receptor antibody-positive (AChR-Ab+) gMG whose symptoms were not adequately controlled by oral medications and/or intravenous immunoglobulin who received efgartigimod between January 2022 and January 2024 were retrospectively evaluated.
First line treatment with subcutaneous efgartigimod in impending myasthenic crisis: a case report.

In acetylcholine receptor (AChR) antibody-positive generalized myasthenia gravis (gMG), neonatal Fc-receptor (FcRn) inhibition has broadened the therapeutic spectrum. Myasthenic crisis (MC), heralded by an impending myasthenic crisis (iMC), is a critical condition requiring treatments with rapid onset and sustained efficacy. Currently treatments used for iMC, including intravenous immunoglobulins and plasma exchange/immunoadsorption, have limitations, such as delayed onset of action and potential side effects.

Rozanolixizumab, a humanised immunoglobulin (Ig) G4 monoclonal antibody that selectively inhibits binding of IgG to the neonatal Fc receptor (FcRn), was evaluated in an embryo-foetal enhanced pre- and postnatal development (ePPND) study. Pregnant female cynomolgus monkeys (19 per group) received subcutaneous rozanolixizumab 50mg/kg or 150mg/kg or vehicle every 3 days from gestation day 20 until delivery. The proportion of pregnancy losses was 15.
