Used in the treatment of inflammatory diseases such as asthma, particularly in patients with elevated type 2 inflammation. It neutralizes the activity of interleukin-13 (IL-13), a key cytokine involved in airway inflammation, mucus production, and bronchial hyperresponsiveness. By blocking IL-12 signaling, it helps reduce asthma exacerbations and improve lung function. Investigated for use in atopic dermatitis and other allergic conditions where IL-13 plays a pathogenic role. Employed as a reference standard in bioassays and drug development for evaluating anti-IL-13 therapeutics.
