AGY is a long-established specialist in the prevention, diagnosis and treatment of allergies. Pollinex Quattro (PQ) Grass, the subcutaneous allergy immunotherapy (AIT), continues to gain market share despite being available in the EU only on a ‘Named-Patient’ basis. Trials designed to obtain regulatory approval as a biologic for PQ Birch in Europe, and for PQ Grass in both Europe and the US, are well advanced. Recruitment to the Phase II PQ Grass trial is complete: more than 440 patients have undergone conjunctival provocation testing in a placebo-controlled, dose-response and safety study. Data are now expected in early 2H calendar 2018.
