Program Description

This enduring webcast addresses the pathogenesis and guideline recommendations for CIDP, as well as the integration of newer therapies. The activity will focus on:

CIDP – It is an immune-mediated syndrome

Pathophysiology – CIDP has been associated with pathophysiologic mechanisms that are not fully understood and likely differ across patient groups, including T-cell and macrophage infiltration, B-cell involvement, and the complement pathway.

EAN/PNS Guidelines for the Diagnosis of CIDP – The 2021 EAN/PNS criteria for CIDP allow a better characterization of CIDP variants and more appropriate treatment for patients

Diagnostic pitfalls in CIDP – Diagnostic pitfalls in CIDP frequently lead to misdiagnosis rates as high as 30% to 50% in clinical practice.

  • Clinical Pitfalls
  • Electrodiagnostic (EDx) Pitfalls
  • Laboratory and Imaging Pitfalls

Treatment/Management of CIDP – With multiple phenotypic variations in clinical presentation and diverse pathophysiological mechanisms, treatment of patients with CIDP is complex and typically tailored to the individual patient.

  • Immunoglobulin (IgG) Treatment – Intravenous immunoglobulin (IVIG) 10%; GAMMAGARD LIQUID, also known as Kiovig, for CIDP
  • Subcutaneous Immunoglobulin (SCIG) – SCIG is available in vials or pre-filled syringes (PFS) and can be administered via pump or manual injection to treat CIDP
  • Plasma Exchange – Plasma exchange, also known as plasmapheresis, is a technique that replaces plasma in a patient’s blood
  • Corticosteroid Treatment – Corticosteroid treatment may provide longer therapy-free remission compared with IVIG
  • Neonatal Fc Receptor Antagonist – The FcRn is responsible for preventing IgG degradation by recycling circulating IgG
    • Efgartigimod – First-in-class neonatal Fc receptor antagonist for the treatment of CIDP
    • Batoclimab and nipocalimab are currently in phase 2 and 3 studies, respectively
  • Complement Inhibitors – Complement activation serves as a link between the adaptive and innate immune systems, through the direct binding of receptors expressed on T cells, B cells, macrophages, and by modulating the function of dendritic cells
    • Riliprubart – A novel complement C1S inhibitor, undergoing a proof-of-concept study in people with CIDP
  • Other Treatment Options – Immunosuppressive and B-cell depletion therapies

Intended Audience

This activity is designed to meet the educational needs of neurologists, neuromuscular disease specialists, specialty nurse practitioners, specialty physician assistants, and other health care providers who manage patients with chronic inflammatory demyelinating polyneuropathy (CIDP).

Commercial Supporter

Supported by an educational grant from argenx US Inc.

Learning Objectives

Upon completion of the educational activity, participants should be able to:

  • Integrate information on the pathophysiology, EAN/PNS guideline recommendations, and diagnostic pitfalls of CIDP.
  • Implement appropriate patient-specific factor-based and novel targeted therapies for CIDP
