Key Factors Driving the Growth of the Chronic Inflammatory Demyelinating Polyneuropathy Market 

• Rising Prevalence and Improved Diagnosis of CIDP: Increasing awareness among neurologists and healthcare professionals has led to earlier and more accurate diagnosis of CIDP. Advancements in diagnostic techniques, including electrophysiological testing, imaging technologies, and biomarker research, are improving disease identification, thereby expanding the treatable patient population.
• Growing Demand for Advanced Therapies: The market is witnessing increased demand for targeted and long-acting therapies that offer improved efficacy, reduced relapse rates, and enhanced patient convenience. Novel immunotherapies, subcutaneous immunoglobulin (SCIG) formulations, FcRn inhibitors, monoclonal antibodies, and complement-targeted therapies are gaining attention as alternatives to traditional intravenous immunoglobulin (IVIG), corticosteroids, and plasma exchange.
• Increasing Adoption of Immunoglobulin Therapies: Immunoglobulin therapies remain the standard of care for CIDP treatment, and their continued adoption is contributing substantially to market growth. The availability of both intravenous and subcutaneous formulations has improved treatment accessibility and patient compliance.
• Expanding Research and Development Activities: Pharmaceutical and biotechnology companies are significantly investing in research and development to introduce innovative therapies for CIDP. The growing clinical pipeline of therapies such as Riliprubart (Sanofi), Batoclimab (Immunovant), Empasiprubart (argenx), NVG-2089 (Nuvig Therapeutics), DNTH103 (Dianthus Therapeutics), TAK-881 and TAK-411 (Takeda), and others, along with increased regulatory support for rare neurological disorders, is expected to accelerate market expansion over the coming years.

Ramandeep Singh, senior consultant of forecasting at DelveInsight, said that the CIDP treatment still faces challenges, as many current therapies have safety concerns and a slow onset of action. Older medication classes often come with troublesome side effects, highlighting the need for safer and more effective options. Encouragingly, new therapies in development offer hope for significant advancements in managing CIDP.

Chronic Inflammatory Demyelinating Polyneuropathy Market Analysis

• The primary objective of treatment in CIDP is to suppress immune-mediated demyelination, prevent irreversible axonal damage, restore motor and sensory function, and maintain long-term disease remission while minimizing therapy-associated adverse effects. 
• As CIDP is a chronic autoimmune neuropathy characterized by relapsing or progressive peripheral nerve injury, treatment strategies primarily focus on modulating the dysregulated immune response underlying nerve damage.
• Standard first-line treatment options include corticosteroids, intravenous immunoglobulin (IVIg), and plasma exchange (PLEX), each acting through distinct immunomodulatory mechanisms. 
• Corticosteroids, including prednisone and dexamethasone, help reduce inflammatory activity and are generally initiated at higher doses followed by gradual tapering once clinical improvement or disease stabilization is achieved.
• Subcutaneous immunoglobulin (SCIg) has increasingly become an important maintenance therapy option due to its ability to provide stable immunoglobulin levels, enable home-based administration, and improve patient convenience and quality of life. 
• Currently approved therapies include SCIg products such as HYQVIA and FcRn inhibitors such as VYVGART Hytrulo, which are indicated for maintenance treatment or relapse prevention in adults with CIDP. 
• Plasma exchange, which removes circulating pathogenic autoantibodies and immune complexes, may induce rapid symptomatic improvement and is particularly beneficial in severe or treatment-refractory cases, although therapeutic benefits are often temporary.
• Treatment selection is guided by disease severity, progression, and patient comorbidities. Patients with mild disease may benefit from supportive measures such as rehabilitation, physiotherapy, and lifestyle modifications, whereas moderate-to-severe CIDP generally requires immunomodulatory intervention. 
• Additionally, several emerging therapies are advancing through clinical development, including Riliprubart from Sanofi, Batoclimab from Immunovant, and Claseprubart (DNTH103) from Dianthus Therapeutics, all of which are being investigated for their potential to enhance disease control and reduce relapse frequency.

Chronic Inflammatory Demyelinating Polyneuropathy Competitive Landscape

Some of the CIDP drugs under development include Riliprubart (Sanofi), Batoclimab (Immunovant), Empasiprubart (argenx), NVG-2089 (Nuvig Therapeutics), DNTH103 (Dianthus Therapeutics), TAK-881 and TAK-411 (Takeda), and others.

Sanofi's Riliprubart (SAR445088) is a potential first-in-class IgG4 humanized monoclonal antibody designed to selectively inhibit activated C1s within the classical complement pathway of the innate immune system. By targeting C1s, the therapy may suppress key inflammatory processes involved in demyelination and axonal injury in Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). The drug is administered via a convenient subcutaneous route and is currently undergoing Phase III clinical evaluation for the treatment of CIDP.

Immunovant's Batoclimab is a human monoclonal antibody targeting the neonatal Fc receptor (FcRn), with potential immunomodulatory effects. It binds to FcRn at the IgG binding site, blocking the interaction between FcRn and immunoglobulin G (IgG). This inhibition prevents FcRn-mediated IgG recycling, promotes IgG degradation, and reduces IgG-driven inflammatory activity. Since IgG plays a central role in several autoimmune disorders, including CIDP, batoclimab may help mitigate disease-associated inflammation.

In March 2025, Immunovant announced topline results from its Phase IIb trial of batoclimab in CIDP, reporting clinically meaningful improvements in disability scores during the initial 12-week treatment period. Notably, patients who achieved greater reductions in IgG levels demonstrated higher response rates.

The anticipated launch of these emerging therapies are poised to transform the chronic inflammatory demyelinating polyneuropathy market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the chronic inflammatory demyelinating polyneuropathy market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.

What is Chronic Inflammatory Demyelinating Polyneuropathy?

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare autoimmune neurological disorder in which the body's immune system mistakenly attacks the myelin sheath, the protective covering surrounding peripheral nerves. This damage disrupts nerve signal transmission, leading to progressive weakness, impaired motor function, sensory loss, numbness, tingling, and reduced reflexes, typically affecting the arms and legs. CIDP can develop gradually over weeks to months and may follow either a relapsing-remitting or steadily progressive course. Although the exact cause remains unclear, early diagnosis and treatment with therapies such as corticosteroids, intravenous immunoglobulin (IVIg), or plasma exchange can help manage symptoms, improve nerve function, and prevent long-term disability.
