Chronic Inflammatory Demyelinating Polyneuropathy Overview

Chronic inflammatory demyelinating polyneuropathy is a rare neurological disorder characterized by inflammation and damage to the protective covering of nerves, known as the myelin sheath. This damage disrupts the communication between nerves and muscles, leading to progressive weakness and impaired sensory function. CIDP is clinically classified into typical and atypical forms. The typical form, the most common, involves symmetrical polyneuropathy, where both proximal and distal muscles are equally affected, leading to widespread weakness and sensory deficits. Symptoms usually progress gradually, but severity varies among patients, impacting walking, fine motor skills, and daily activities.

Chronic Inflammatory Demyelinating Polyneuropathy Marketed Drugs

  • HYQVIA (Immune Globulin Infusion 10% [Human] with Recombinant Human Hyaluronidase): Takeda

HYQVIA is an immunostimulant combining human immunoglobulin (IG 10%) with recombinant human hyaluronidase, enabling SC for easier administration. This treatment offers a convenient alternative to IVIg by allowing larger-volume, less frequent SC due to enhanced absorption. HYQVIA modulates the immune system to reduce autoimmune damage to the nerves in CIDP. In January 2024, the US FDA approved HYQVIA for the maintenance treatment of CIDP in adults. The European Commission also approved it for the same purpose, and the UK’s MHRA granted approval in March 2024. Takeda filed for approval in Japan in August 2024.

  • VYVGART HYTRULO (Efgartigimod Alfa and Hyaluronidase-Qvfc): Argenx

VYVGART HYTRULO is a coformulation of efgartigimod alfa and recombinant human hyaluronidase, designed to enhance SC absorption. It works by reducing autoantibodies implicated in CIDP through inhibition of the FcRn receptor. Approved by the US FDA in June 2024, it received orphan drug designation for CIDP in 2021. This therapy offers a convenient option for maintaining remission via SC administration.

  • GAMMAGARD LIQUID/KIOVIG (Immune Globulin Infusion [Human] 10% Solution): Takeda

GAMMAGARD LIQUID/KIOVIG is a ready-to-use IV formulation of IVIg derived from human plasma, offering a broad spectrum of antibodies. It works by modulating the immune system, reducing inflammation, and preventing further nerve damage in CIDP. Clinical studies have shown its effectiveness in improving muscle strength and functional ability, helping manage symptoms and maintain long-term stability. It was approved by the US FDA in January 2024 for adults with CIDP. In May 2019, KIOVIG was also approved in the EU for treating CIDP in adults, children, and adolescents (0–18 years).

Chronic Inflammatory Demyelinating Polyneuropathy Emerging Drugs

  • Riliprubart (SAR445088): Sanofi

Riliprubart (SAR445088) is a potential first-in-class, IgG4 humanized monoclonal antibody that selectively inhibits activated C1s in the classical complement pathway of the innate immune system. By blocking C1s, riliprubart has the potential to inhibit key inflammatory mechanisms that drive demyelination and axonal damage in CIDP. Riliprubart has convenient subcutaneous route of administration. Currently the drug is in Phase III stage of Clinical trial evaluation for the treatment of CIDP.

  • Batoclimab (HL161): Immunovant Sciences GmbH/HanAll Pharma/Roivant Sciences

Batoclimab is a human monoclonal antibody directed against the Neonatal Crystallizable Fragment Receptor (FcRn), with potential immunomodulating activity. Upon administration, batoclimab targets and binds to FcRn at the Immunoglobulin G (IgG) binding site, thereby preventing the interaction between FcRn and the serum protein IgG. By preventing FcRn/IgG binding, batoclimab blocks the FcRn-mediated rescue of IgG, enables IgG degradation and prevents IgG-mediated inflammation. IgG plays a key role in many autoimmune diseases and is an important factor in inflammatory processes. Immunovant reported topline results in March 2025 from its Phase IIb study of batoclimab in CIDP, showing meaningful improvements in disability scores during the initial 12-week period. Patients with deeper reductions in IgG levels demonstrated higher responder rates.

Chronic Inflammatory Demyelinating Polyneuropathy Market Outlook

Chronic inflammatory demyelinating polyneuropathy, though classified as a rare disease, has gained increasing recognition in recent years. This is largely due to improvements in diagnostic techniques, greater awareness among healthcare professionals, and a deeper understanding of the condition. Management of CIDP typically involves a combination of pharmacological therapies and supportive interventions, with the primary objectives to suppress inflammation, modulate immune responses, and improve motor and sensory function.

Chronic Inflammatory Demyelinating Polyneuropathy Treatment Landscape

The treatment landscape for CIDP has advanced with a multi-faceted approach, combining medications, and supportive care. Corticosteroids, such as prednisone and dexamethasone, are often the initial treatment. While they are effective in inducing remission, they carry a high risk of significant long-term side effects, including osteoporosis, weight gain, and increased susceptibility to infections. These adverse effects often necessitate combination therapies with steroid-sparing agents, which may not be universally effective. Plasma exchange has shown short-term efficacy in removing harmful autoantibodies and improving symptoms. However, it is an invasive procedure that requires highly specialized centers and trained personnel, limiting its accessibility, IVIg has become the gold standard due to its demonstrated efficacy in long-term disease control and symptom improvement. Despite this, IVIg is costly, time-consuming, and heavily reliant on donor plasma, raising concerns about its long-term availability.
