Innovative Test Enhances Quality Assurance for Allergy Treatments

Sat 7th Jun, 2025

An interdisciplinary team from the Paul-Ehrlich-Institut (PEI), specializing in Allergology and Veterinary Medicine, has unveiled a groundbreaking laboratory test designed to accurately measure the content of adjuvanted allergoids in finished allergy medications. This advancement addresses the limitations of previous quality control methods, which could only be performed at intermediary stages of production due to the complex composition of these products, which include both adjuvants and chemically modified allergens known as allergoids.

The new testing method marks a significant breakthrough in quality assurance for allergy therapies. According to a recent report published in the journal Allergy, allergen immunotherapy (AIT) is a critical treatment for various allergies. Allergoids, as modified allergens, play a pivotal role in specific immunotherapy by helping to adjust the immune response and achieving tolerance to allergens. The precise measurement of these allergoids is essential for effective treatment outcomes, yet quantifying their content in finished products has been previously unfeasible.

The Paul-Ehrlich-Institut oversees the quality, efficacy, and safety of therapy allergens, which are mandated by law to undergo official batch testing conducted by the institute. A dedicated research team, led by Dr. Frank Führer from the Allergens Product Testing Section, has developed a novel method that enables the accurate quantification of allergoid content specifically in grass pollen AIT products.

The newly devised assay leverages an antibody-based detection method akin to enzyme-linked immunosorbent assays (ELISA), utilizing a fluorescence detection system. The specificity of the antibodies employed allows for precise measurement of allergoid content in therapy allergen products. This innovative immunoassay facilitates reliable detection of specific grass pollen allergoids without the necessity for animal testing, thereby enhancing ethical standards in product testing.

This advancement is expected to significantly bolster quality assurance protocols for AIT preparations, potentially leading to their standardization across the industry. As research continues to evolve, the implications of this test could be profound, improving treatment safety and efficacy for patients suffering from allergic conditions.
