SQ house dust mite (HDM) SLIT-tablet provides clinical improvement in HDM-induced allergic rhinitis

House dust mite (HDM) allergy represents a highly prevalent inhalant allergy, and exposure to HDM allergens results in allergic rhinitis with persistent symptoms that may not be adequately controlled with available allergy pharmacotherapy. Allergy immunotherapy constitutes a complementary treatment option targeting the underlying immunological mechanisms of allergic disease and represents the only treatment with a potential for disease modification and long-term efficacy. As traditional allergy immunotherapy delivered by subcutaneous injection of specific HDM allergens involves a time-consuming treatment regimen and a risk of systemic adverse reactions, sublingually administered allergy immunotherapy (SLIT) has been investigated as a more convenient treatment option with similar levels of efficacy and an improved safety profile that allows for at-home daily administration. In this Drug Profile, we provide a review of the clinical data behind the SQ HDM SLIT-tablet, which was recently approved for the treatment of HDM-induced allergic rhinitis by regulatory authorities in Europe and Japan.
