The Impact of Tezepelumab in Uncontrolled Severe Asthma: A Systematic Review of Randomized Controlled Trials

[Tezepelumab: a new option for the treatment of severe asthma]

In Latin America, asthma is a public health problem with a significant impact on both patients and health systems. The greater understanding of the pathophysiology and the recognition of the central role that inflammation has in the severity of asthma has favored the development of monoclonal antibodies that have IL-5, IL-4, IL-13 and IgE as therapeutic targets. Although these therapeutic alternatives promote better control of the disease, not all patients respond favorably to these treatments. Therefore, it is of particular interest to explore monoclonal antibodies such as Tezepelumab, directed against thymic stromal lymphopoietin (TSLP), an alarmin (epithelial cytokine) that participates in the initiation and perpetuation of inflammation in Asthma. Therefore, in this review, we will show the clinical efficacy of tezepelumab in reducing the annual rate of exacerbations, improving lung function, and reducing bronchial hyperreactivity, regardless of the patient's baseline biomarker levels. Therefore, this new molecule is a highly effective therapeutic option for patients with severe asthma.
