NCT00750867 ↗	Treatment of Multiple System Atrophy Using Intravenous Immunoglobulins	Completed	University of Massachusetts, Worcester	Phase 2	2008-06-01	Multiple System Atrophy (MSA) is a progressive sporadic neurodegenerative disorder leading to widespread loss of brain cells that results in parkinsonian, cerebellar and autonomic dysfunction. The cause of the MSA remains unclear. Available treatment is symptomatic only and does not alter the course of disease. Although the cause of MSA remains unclear, there is evidence of presence of common neuroinflammatory mechanisms in the MSA brains including activation of microglia and production of toxic cytokines. This research protocol is based on hypothesis that the MSA progression can be altered by blocking the neuroinflammatory activity. This protocol includes administration of intravenous immunoglobulin (IVIg). IVIg contains antibodies derived from human plasma which can block the inflammatory responses in the brain that can lead to loss of brain cells.

NCT02111161 ↗	Immunoglobulin for Necrotizing Soft Tissue Infections: a Randomised Controlled Trial	Completed	Anders Perner	Phase 2	2014-04-01	The purpose of this study is to estimate the effect of intravenous polyspecific immunoglobulin G (IVIG) compared with placebo (saline) on the patient-reported outcome measure Physical Component Summary Score (PCS) of the SF-36 in patients with necrotizing soft tissue infections (NSTI).
NCT02308982 ↗	Investigating the Role of Early Intravenous Immunoglobulin Treatment for Children With Encephalitis	Unknown status	CSL Behring	Phase 3	2016-01-01	This is a phase III multi-centre randomised, double blind, placebo controlled trial to assess the role of intravenous immunoglobulin in the treatment of children with encephalitis. The primary objective is to find out whether early use of IVIG treatment improves neurological outcomes of children with encephalitis. 308 children with encephalitis, aged 6 weeks to 16 years will be recruited in 30 hospitals in the United Kingdom. Participants will be randomised to receive two doses of IVIG or matching placebo in addition to other standard treatments, within the first five days of hospital admission. Each participant will be followed up for 12 months. During this period, information on clinical, radiological and laboratory investigations will be collected. Neurological outcomes will be assessed by the use of questionnaires at 6 and 12 months, and a neuropsychological assessment at 12 months.

Clinical Trials Landscape of PRIVIGEN

Recent Clinical Trial Developments

Over the past 12–18 months, PRIVIGEN has undergone several updates in clinical trials aimed at expanding its indications and optimizing its safety profile. Notably:

1. Enhanced Safety Profile in Autoimmune Disorders
   A Phase IV observational study published mid-2022 evaluated the long-term safety and efficacy of PRIVIGEN in patients with Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP). The data indicated sustained improvement with minimal adverse events, reinforcing the drug’s profile for autoimmune neuromuscular disorders [1].

2. Expansion into Secondary Immunodeficiency Conditions
   A pivotal Phase III trial completed in late 2022 assessed PRIVIGEN’s efficacy in secondary immunodeficiency secondary to hematologic malignancies. Results demonstrated comparable efficacy to existing therapies with a favorable safety profile, paving the way for expanded indications.

3. Comparative Efficacy and Pharmacokinetic Studies
   Recent pharmacokinetic (PK) studies compared PRIVIGEN to competitor products, highlighting similar or superior serum IgG trough levels, which suggest consistent immune protection [2].

Ongoing and Planned Clinical Trials

• Pediatric Population Study (Phase IV): A study initiated in early 2023 aims to evaluate safety and dosing in pediatric patients with primary immunodeficiencies.
• Autoimmune Disease Management: An upcoming trial aims to compare PRIVIGEN efficacy against subcutaneous immunoglobulin (SCIG) preparations in conditions like myasthenia gravis.
• Biosimilar Development: Research into biosimilar versions of PRIVIGEN is ongoing, potentially reducing costs and expanding access.

Regulatory Status & Approvals

PRIVIGEN maintains FDA approval for primary immunodeficiency (since 1981) and is also approved in the EU and other markets. The recent clinical updates potentially support applications for new indications, leading to increased label expansion opportunities.
