ALK

The term "ALK" refers to a range of allergen immunotherapy (AIT) products manufactured by the Danish pharmaceutical company ALK-Abelló. [7] These products are biologic drugs used to treat allergies by reprogramming the immune system. [12] The portfolio includes treatments for common environmental allergies such as those caused by grass pollen, tree pollen, house dust mites, and insect stings. [2, 4, 5, 6] The underlying principle of these therapies is to administer gradually increasing doses of a specific allergen to the patient, which helps the immune system to build tolerance, thereby reducing or eliminating allergic symptoms like those seen in allergic rhinoconjunctivitis. [3, 5] ALK provides these therapies in multiple forms, including subcutaneous injections (SCIT), such as ALK SQ Depot and ALK Avanz, and sublingual tablets (SLIT). [12] The provided clinical trial information specifically evaluates SCIT products containing grass pollen allergen extracts for treating seasonal allergic rhinoconjunctivitis.
