Intravenous immunoglobulin is a pooled antibody, and a biological agent used to manage various immunodeficiency states and a plethora of other conditions, including autoimmune, infectious, and inflammatory states. The ultimate goal of this therapy is to normalize a compromised immune system.
IVIg therapy has been approved for the treatment of Immune Thrombocytopenia (ITP), Guillain-Barre Syndrome (GBS), Kawasaki's disease, Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and Multifocal motor neuropathy (MMN) and many others. Furthermore, IVIg is widely used off-label for treating immune-mediated, neurological, hematological, and dermatological diseases.
Several companies-such as Grifols Therapeutics, ADMA Biologics, Takeda, LFB Biopharmaceuticals, OCTAPHARMA, Pfizer, CSL Behring, Biotest AG, and GC Biopharma-are actively involved in the development and commercialization of intravenous immunoglobulin (IVIG) therapies, with many already having approved products established in the market.
PRIVIGEN stands out as one of the few IVIG therapies approved across all 7MM (US, EU5, and Japan) markets, reflecting its broad clinical acceptance and regulatory recognition for treating immune deficiencies and autoimmune conditions.
In September 2024, GC Biopharma USA, Inc. announced the launch and distribution of its IG product ALYGLO (IVIG), the company's first 10% IVIG therapy for the treatment of adult patients aged 17 years and older with PI.
In full year 2024,BIVIGAM generated a revenue of approximately USD 50 million in the United States.
Despite its widespread use, the IVIG market faces several challenges, including supply limitations due to reliance on human plasma, high production costs associated with complex manufacturing processes, and payer resistance to high-priced biologics-particularly for off-label indications-which collectively hinder consistent access, pricing flexibility, and broader market penetration.
Looking ahead, continued innovation in manufacturing, improved donor recruitment strategies, and expanding clinical evidence for new indications will be critical to overcoming these hurdles and sustaining growth in the global IVIG market.

IVIG Understanding and Treatment Algorithm
IVIG Overview
Immunoglobulins (Ig)-commonly referred to as antibodies-are glycoproteins produced by plasma cells in response to antigenic stimulation. They play a pivotal role in both physiological and pathological immune responses. As essential components of the adaptive immune system, immunoglobulins are classified based on the structure of their heavy chains into five major types: IgG, IgA, IgM, IgE, and IgD, each with distinct immunological roles. Among these, IgG is the most prevalent, comprising approximately 75-80% of total plasma antibodies (700-1600 mg/dL). It is further categorized into four subclasses-IgG1, IgG2, IgG3, and IgG4-each differing in function and distribution. IgA, which makes up around 15% of circulating immunoglobulins (70-400 mg/dL), plays a key role in mucosal immunity and exists in two subtypes: IgA1 and IgA2. IgM, though present at lower concentrations (40-230 mg/dL), is the first antibody produced during an immune response and is crucial in the initial defense against pathogens.
Intravenous Immunoglobulin (IVIG): From Replacement Therapy to Immunomodulatory Agent
IVIG products are composed of pooled IgG antibodies sourced from thousands of healthy donors. Initially introduced as a replacement therapy for patients with primary and secondary immunodeficiency disorders, IVIG has since demonstrated significant immunomodulatory properties. This expanded its therapeutic utility into a broad range of conditions, including neurological, hematological, infectious, and autoimmune diseases-solidifying its role as a versatile and indispensable treatment modality.
IVIG Market Overview
IVIG preparations consist of pooled IgG antibodies derived from thousands of donors, initially developed as a replacement therapy for primary and secondary immunodeficiency disorders. However, subsequent research revealed its profound immunomodulatory effects, making IVIG a cornerstone therapy in neurological, hematological, infectious, and autoimmune diseases. This paradoxical role of IgG-as both a driver of autoimmune pathology and a therapeutic agent-is particularly evident in conditions such as rheumatoid arthritis, systemic lupus erythematosus , immune thrombocytopenia , autoimmune hemolytic anemia , and chronic inflammatory demyelinating polyneuropathy and others. Despite its efficacy, the precise immunoregulatory mechanisms of IVIG remain incompletely understood.
IVIG Epidemiology
The IVIG epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented as total cases of selected indications for IVIG, total eligible patient pool of selected indication for IVIG, total treated cases in selected indications for IVIG in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain), and the United Kingdom, and Japan from 2020 to 2034.
In 2024, chronic inflammatory demyelinating polyneuropathy affected approximately 21,000 patients in the United States.
Primary Immunodeficiency Diseases had an estimated prevalence of around 38,000 cases across the EU4 and the UK in 2023.
IVIG Drug Chapters
The drug chapter segment of the IVIG reports encloses a detailed analysis of approved IVIG late-stage (Phase III and Phase II) IVIG. It also helps understand the IVIG's clinical trial details, expressive pharmacological action, agreements and collaborations, approval and patent details, advantages and disadvantages of each included drug and the latest news and press releases.
Marketed Drugs
YIMMUGO (immune globulin intravenous, human - dira): Biotest AG
YIMMUGO is an immune globulin intravenous (IVIG), human - dira, 10% liquid indicated for the treatment of primary humoral immunodeficiency (PI) in patients 2 years of age or older. It is manufactured by Biotest AG using pooled plasma from healthy donors and provides a broad spectrum of Immunoglobulin G (IgG) antibodies. In July 2024, Biotest AG announced that its IVIG, YIMMUGO, had been approved in the United States for the treatment of patients with primary immunodeficiencies.
ALYGLO (IVIG, human-stwk): GC Biopharma
ALYGLO is indicated for the treatment of PI in adults aged 17 years and older. This includes, but is not limited to, congenital agammaglobulinemia, common variable immunodeficiency (CVID), Wiskott-Aldrich syndrome, and severe combined immunodeficiencies. It contains a high concentration of IgG antibodies derived from pooled human plasma, which helps bolster the immune system against infections. Administered every 21 to 28 days, ALYGLO is crucial for patients with conditions like common variable immunodeficiency and severe combined immunodeficiencies. While it effectively reduces infection rates, patients should be monitored for potential side effects, including thrombosis and renal complications. In December 2023, GC Biopharma USA announced that the US FDA had approved ALYGLO 10% Liquid, formerly referred to as "G5107B," for the treatment of adult patients aged 17 years and older with PI.
Emerging Drugs
TAK-880: Takeda
TAK-880, developed by Takeda, is a low IgA-IgG intravenous immunoglobulin formulation being investigated for the treatment of primary immunodeficiency diseases, particularly in individuals hypersensitive to IgA TAK-880 is currently being filed with the FDA and EU for the approval in treatment of primary immunodeficiency diseases.
IVIG Market Outlook
Several intravenous immunoglobulin (IVIG) formulations have received regulatory approval in the United States, each designed to meet distinct clinical requirements. These include: BIVIGAM, CARIMUNE, FLEBOGAMMA, GAMMAGARD S/D (low IgA formulation), GAMMAGARD Liquid, GAMMAKED, GAMMAPLEX, GAMUNEX, OCTAGAM, and PRIVIGEN.
In recent years, the global immunoglobulin shortage has become a critical issue, with Japan facing similar challenges, particularly since 2019. The sharp rise in immunoglobulin demand has made urgent imports unavoidable. Analysis suggests two key factors behind this surge: the approval of immunoglobulin for preventing chronic inflammatory demyelinating polyneuropathy (CIDP) progression and the introduction of concentrated formulations.
Despite its promising potential, the widespread production and adoption of IVIg therapy remain challenging due to two primary factors. First, securing a stable supply of plasma donors is difficult-an issue exacerbated during the pandemic when blood collection centers faced widespread closures. Second, IVIg administration requires hospital or ambulatory center visits, as it must be delivered by trained medical professionals, adding to patient burden and healthcare system constraints.
