Used in the treatment of severe asthma, particularly in patients who do not respond well to standard therapies. It targets and blocks thymic stromal lymphopoietin (TSLP), a protein that plays a key role in initiating airway inflammation. By inhibiting TSLP, it helps reduce the frequency of asthma attacks and improves lung function. Also being studied for potential use in other respiratory conditions like chronic obstructive pulmonary disease (COPD) and allergic diseases such as atopic dermatitis and nasal polyps. Its mechanism offers a targeted approach to interrupting inflammation early in the immune response pathway.
