DelveInsight’s “Guillain-Barre Syndrome Market Insight, Epidemiology And Market Forecast – 2034” report delivers an in-depth understanding of the Guillain-Barre Syndrome treatment market, historical and forecasted epidemiology, as well as market trends across the US, EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan. The report comprehensively evaluates the current treatment landscape, emerging therapies, market share of individual treatments, and GBS market forecasts through 2034, providing crucial insights for stakeholders in the Guillain-Barre Syndrome therapeutic area.
Guillain-Barré Syndrome Market Outlook
According to DelveInsight’s analysis, the Guillain-Barré Syndrome market is expected to experience significant growth during the forecast period (2024–2034), driven by various market-driving factors such as the rising Guillain-Barré syndrome incidence, increasing awareness, the promising pipeline of innovative treatment options, and increased investment by pharmaceutical companies for research and development. The overall Guillain-Barré syndrome therapeutics market is expected to grow at a significant CAGR over the forecast period due to the anticipated approval of emerging therapies under development.
Furthermore, the United States holds a significant share of the overall 7MM Guillain-Barré syndrome market, primarily attributed to the country’s higher occurrence of the condition and the elevated cost of available treatments. This dominance is projected to persist, especially with the potential early introduction of new products.

Guillain-Barré Syndrome Epidemiology
According to DelveInsight’s estimates, Guillain-Barré syndrome affects about one or two people each year in every 100K population, with people of all ages being affected. Additionally, it is more common in adults and males.
In Europe and North America, Acute Inflammatory Demyelinating Polyradiculoneuropathy (AIDP) is the most frequent form of GBS, accounting for around 90% of cases. Furthermore, Acute motor axonal neuropathy (AMAN) affects the axons of the nerves going to the muscles and is the most common form in some Asian countries.
The DelveInsight report further categorizes the Guillain-Barre Syndrome patient population into several groups for analysis. It differentiates between three different forms of GBS: Acute inflammatory demyelinating polyradiculoneuropathy (AIDP), which predominantly affects the myelin and is the most common form in America and Europe; Acute motor axonal neuropathy (AMAN), which affects the axons of nerves going to muscles and is most common in some Asian countries; and Acute motor and sensory axonal neuropathy (AMSAN), which affects the axons of both motor and sensory nerves. This classification is essential for understanding the distribution, progression, and treatment responses of different GBS types and is crucial for accurate epidemiological assessment.

Guillain-Barré Syndrome Treatment Landscape
While there is no definitive cure for GBS, several treatment options are aimed at Guillain-Barre Syndrome management. The predominant treatment for Guillain-Barré Syndrome patients is intravenous immunoglobulin (IVIG), which works by blocking the effects of harmful antibodies, and plasma exchange (PE) therapy, which removes harmful substances, including antibodies that cause GBS. IVIG is more convenient and more widely available than PE, but both are equally helpful. Early treatment within the first 2 weeks after symptom onset is preferable.
According to the DelveInsight report, the Guillain-Barre Syndrome therapies pipeline is promising, with several novel treatments in development. ANX005 by Annexon is a clinical-stage investigational monoclonal antibody intended to treat patients with antibody-mediated autoimmune and complement-mediated neurodegenerative disorders. This novel therapy is formulated for IV administration and is designed to inhibit C1q and the entire classical complement pathway. The drug has received both fast-track and orphan drug designations from the FDA for Guillain-Barre Syndrome treatment.
Similarly, Imlifidase by Hansa Biopharma is an antibody-cleaving enzyme that specifically targets IgG and inhibits IgG-mediated immune response. Based on the positive Phase 2 results and an indirect comparison with the International Guillain-Barré Syndrome Outcome Study (IGOS), Hansa Biopharma is considering the next steps for imlifidase in GBS treatment. The drug has also been granted orphan drug designation by the US FDA.
Efgartigimod (arGEN-X) and Eculizumab (Alexion Pharmaceuticals) are also advancing rapidly through clinical trials for Guillain-Barré Syndrome, with expected further clinical trials and FDA approvals soon.
Guillain-Barré Syndrome Recent Developments
Recent developments highlight the dynamic nature of the Guillain-Barre Syndrome treatment landscape. ANX005 (Annexon, Inc.) continues to show promise in Guillain-Barre Syndrome Phase 3 clinical trials. Positive results were presented at the 2025 American Academy of Neurology (AAN) Annual Meeting in April 2025. ANX005 has received FDA Fast Track and Orphan Drug designations, with plans to submit a BLA in the first half of 2025.
Efgartigimod (arGEN-X), an FcRn blocker, is being evaluated in a Phase 3 trial (NCT05701189) for GBS. The last update was submitted in March 2025, showing positive results. The Phase 2 study results of Imlifidase in Guillain-Barre Syndrome patients were also highlighted at the 2025 PNS Annual Meeting in May 2025. The study showed promising results, demonstrating rapid improvement in muscle strength and walking ability.
In January 2025, the FDA mandated safety label changes for Pfizer’s ABRYSVO and GlaxoSmithKline Biologicals’ AREXVY (Respiratory Syncytial Virus Vaccines) to include a warning about a potential increased risk of GBS during the 42 days following vaccination. The FDA’s decision was based on postmarketing observational studies and reports, although the available evidence is currently insufficient to establish a causal relationship.

The Guillain-Barré syndrome treatment market is highly competitive, with major players including Annexon, Hansa Biopharma, Alexion Pharmaceuticals, and others, all advancing a variety of therapies through robust R&D and strategic collaborations.
Looking ahead, the GBS market is expected to witness continued innovation driven by enhanced understanding of disease mechanisms and the development of targeted therapies. While significant progress has been made with immunomodulatory treatments, challenges remain in addressing the limited availability of effective treatments, the limited understanding of causes, and the lack of awareness. Scientists are concentrating on finding new treatments and refining existing ones, with ongoing research and continued dedication offering hope for even more effective treatments and ultimately a cure for this challenging condition.
DelveInsight’s analysis underscores that substantial opportunities remain for developing more effective, convenient, and affordable treatment options that can achieve better outcomes and improved quality of life for Guillain-Barré syndrome patients worldwide. As research continues and awareness grows, the Guillain-Barré syndrome market is poised for remarkable expansion and therapeutic innovation in the coming decade.
