Efficacy and Safety of Biologics, Allergen Immunotherapy, and Pharmacotherapies for Moderate-to-Severe Allergic...

The management of moderate-to-severe allergic rhinitis (AR) is challenging given numerous advanced therapies. A comparative, evidence-based treatment hierarchy to guide the selection of biologics, allergen immunotherapy (AIT), and advanced pharmacotherapies is critically lacking due to a paucity of head-to-head trials. This network meta-analysis established a treatment hierarchy for moderate-to-severe AR by comparing the efficacy and safety of biologics, AIT, and key pharmacotherapies.

We analyzed 28 randomized controlled trials (13,312 participants), which evaluated the efficacy and safety of biologics (anti-IgE, anti-IL-4Rα therapies), AIT (evaluated within a 6-month time frame to ensure comparability), and key pharmacotherapies (intranasal corticosteroids alone or combined with antihistamines) for moderate-to-severe AR. Efficacy was assessed by changes in the Total Nasal Symptom Score (TNSS), the Total Ocular Symptom Score (TOSS), and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). A treatment hierarchy was established using surface under the cumulative ranking curve (SUCRA) probabilities.

For the TNSS, anti-IL-4Rα therapy was most effective, followed by anti-IgE therapy and AIT, which surpassed all pharmacotherapies. The combination of intranasal corticosteroid and intranasal antihistamine ranked the highest for ocular symptoms. Anti-IL-4Rα therapy was also superior for improving the RQLQ. Overall, all treatments demonstrated a favorable safety profile. Biologics and AIT did not show a significant increase in adverse events risk compared to placebo.

This network meta-analysis establishes the first comprehensive treatment hierarchy for moderate-to-severe AR. Our findings demonstrate that biologics, particularly anti-IL-4Rα therapy, are the most effective interventions for nasal symptom control, ranking superior to AIT and pharmacotherapies, thus providing a robust, data-driven framework to personalize patient care.
