mixture of grass pollen allergen extracts

Mixture of grass pollen allergen extracts is a biological preparation developed by Diater for the diagnosis and immunotherapy of grass pollen-related allergic conditions, including allergic rhinitis, conjunctivitis, and asthma. The mixture contains extracts from four specific grass species: *Phleum pratense* (timothy grass), *Lolium perenne* (perennial ryegrass), *Poa pratensis* (Kentucky bluegrass), and *Dactylis glomerata* (orchard grass). It functions by modulating the immune system's response to these allergens, typically through desensitization protocols that shift the immune profile from a Th2-mediated IgE response toward a Th1 or regulatory T-cell (Treg) response. The preparation has been evaluated in Phase 2 clinical trials in Spain for biological characterization and standardization using skin prick test responses.
