ADMA Biologics Announces Peer-Reviewed Publication Highlighting New Data From Its Optimized, Proprietary IVIG Manufacturing Process

(MENAFN- GlobeNewsWire - Nasdaq) Optimized Process Demonstrated Effective Removal of Procoagulant Impurities While Maintaining Immunoglobulin Quality and Increasing IgG Yield

No Thromboembolic Events Were Reported for ADMA IVIG Products Manufactured Using the Optimized Process During the Postmarketing Surveillance Period Evaluated

RAMSEY, N.J. and BOCA RATON, Fla., Oct. 15, 2026 (GLOBE NEWSWIRE) -- ADMA Biologics, Inc. (Nasdaq: ADMA) (“ADMA” or the“Company”), a U.S.-based, end-to-end commercial biopharmaceutical company dedicated to manufacturing, marketing and developing specialty biologics, today announced the publication of a peer-reviewed article in Frontiers in Cardiovascular Medicine detailing new data from the Company's optimized, proprietary intravenous immune globulin (“IVIG”) manufacturing process.

The article, titled“Further Optimization of an ADMA Biologics' Proprietary Manufacturing Process to Ensure Removal of Impurities Associated With Thrombosis Risk in IVIG Products,” reports the results of analytical testing performed on three commercial-scale lots of ADMA's IVIG products manufactured using its U.S. Food and Drug Administration (FDA)-licensed further optimized process.

Thromboembolic events (“TEEs”) are rare but serious adverse events associated with immune globulin therapy. Patient-specific risk factors and certain product-related impurities can contribute to the potential risk of these events. ADMA further optimized its proprietary manufacturing process to enhance the removal of procoagulant and other impurities while maintaining immunoglobulin purity, quality and structural integrity.

Key findings reported in the publication include:

• All evaluated procoagulant and product-related impurities, including Factor XIa, IgA, IgM, cholesterol and prekallikrein activator, were measured at or below applicable quantification limits across the three lots tested.
• Two of the three evaluated lots had Factor XIa levels below the limit of quantification. Factor XIa has been associated with thrombotic risk in immune globulin products.
• The three lots demonstrated an average non-activated partial thromboplastin time (“NAPTT”) exceeding 250 seconds, indicating very low procoagulant activity. NAPTT results greater than 200 seconds have been associated with a reduced incidence of TEEs.
• Chromatographic testing detected no immunoglobulin aggregates or fragments.
• The optimized process increased immunoglobulin yield while maintaining product quality and IgG integrity.
• ADMA's postmarketing pharmacovigilance surveillance and the FDA Adverse Event Reporting System received no reports of TEEs associated with ADMA IVIG products manufactured using the further optimized process from July 1, 2025 through July 31, 2026.

“Patients with primary humoral immunodeficiency may require lifelong immune globulin therapy, making product quality and continued manufacturing innovation critically important,” said Adam Grossman, President and Chief Executive Officer of ADMA.“The findings reported in this peer-reviewed publication demonstrate the capabilities of ADMA's proprietary manufacturing platform to remove impurities associated with thrombotic risk while maintaining immunoglobulin quality and increasing IgG recovery. We believe these results further support the differentiated quality profile of our IVIG portfolio and reinforce ADMA's commitment to advancing manufacturing science for the benefit of immune-compromised patients.”

“Thromboembolic events are uncommon but clinically important complications of immunoglobulin therapy, making the control of procoagulant impurities an important component of IVIG manufacturing. The very low procoagulant activity observed in this analysis, together with effective removal of Factor XIa and other impurities and the absence of reported thromboembolic events during the post-marketing observation period, provides reassuring evidence regarding the quality and safety profile of IVIG produced using ADMA's further optimized manufacturing process,” said Dr. Maeve O'Connor, Chief Medical Officer, Consortium of Independent Immunology Clinics (CIIC) & CEO and Medical Director, Integrative Allergy and Immunology Care, Charlotte, NC.

The results should be considered in the context of the study's limitations, including the evaluation of three manufacturing lots and the relatively limited postmarketing surveillance period. Spontaneous adverse-event reporting systems are also subject to underreporting and cannot establish the absence of risk or a causal relationship between a manufacturing process and clinical outcomes. Thrombosis remains a labeled risk for all IVIG products, including ASCENIVTM and BIVIGAM^®.

About ASCENIVTM

ASCENIV (immune globulin intravenous, human – slra 10% liquid) is a plasma-derived, polyclonal, intravenous immune globulin (IVIG). ASCENIV was approved by the United States Food and Drug Administration (FDA) in April 2019 and is indicated for the treatment of primary humoral immunodeficiency (PI), also known as primary immune deficiency disease (PIDD), in adults and pediatric patients (2 years of age and older). ASCENIV is manufactured using ADMA's unique, patented plasma donor screening methodology and tailored plasma pooling design, which blends normal source plasma and respiratory syncytial virus (RSV) plasma obtained from donors tested using the Company's proprietary microneutralization assay. ASCENIV contains naturally occurring polyclonal antibodies, which are proteins that are used by the body's immune system to neutralize microbes such as bacteria and viruses that safeguard against infection and disease. ASCENIV is protected by numerous issued patents in the United States and internationally and a wide range of patent applications worldwide.

Important Safety Information About ASCENIVTM

	WARNING: THROMBOSIS, RENAL DYSFUNCTION AND ACUTE RENAL FAILURE
	Thrombosis may occur with immune globulin intravenous (IGIV) products, including ASCENIV. Risk factors may include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling vascular catheters, hyperviscosity, and cardiovascular risk factors. Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur with the administration of IGIV products in predisposed patients. Such events require immediate medical intervention, if not recognized or managed appropriately, may result in persistent or significant disability or lead to fatal outcome. For patients at risk of thrombosis, renal dysfunction or renal failure, administer ASCENIV at the minimum dose and infusion rate practicable. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.

ASCENIVTM Contraindications:

History of anaphylactic or severe systemic reactions to human immunoglobulin.

IgA deficient patients with antibodies to IgA and a history of hypersensitivity.

ASCENIVTM Warnings and Precautions:

IgA-deficient patients with antibodies against IgA are at greater risk of developing severe hypersensitivity and anaphylactic reactions. Have medications such as epinephrine available to treat any acute severe hypersensitivity reactions. [4, 5.1]

Thrombotic events have occurred in patients receiving IGIV treatments. Monitor patients with known risk factors for thrombotic events; consider baseline assessment of blood viscosity for patients at risk of hyperviscosity. [5.2, 5.4]

In patients at risk of developing acute renal failure, monitor renal function, including blood urea nitrogen (BUN), serum creatinine, and urine output. [5.3, 5.9]

Hyperproteinemia, increased serum viscosity, and hyponatremia or pseudohyponatremia can occur in patients receiving IGIV treatment. [5.4]

Aseptic meningitis syndrome (AMS) has been reported with IGIV treatments, especially with high doses or rapid infusion. [5.5]

Hemolytic anemia can develop subsequent to IGIV treatment. Monitor patients for hemolysis and hemolytic anemia. [5.6]

Monitor patients for pulmonary adverse reactions (Transfusion-related acute lung injury [TRALI]). If transfusion-related acute lung injury is suspected, test the product and patient for antineutrophil antibodies. [5.7]

Because this product is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses, and theoretically, the Creutzfeldt-Jakob disease (CJD) agent. [5.8]

ASCENIVTM Adverse Reactions:

The most common adverse reactions to ASCENIV (≥5% of study subjects) were headache, sinusitis, diarrhea, gastroenteritis viral, nasopharyngitis, upper respiratory tract infection, bronchitis, and nausea.
