Chronic obstructive pulmonary dis-ease(COPD)is the most common chronic airway disease.The current status of treatment based mainly on bronchodilators and ICS is not sufficient for all of COPD patients.Various studies have at-tempted to use biologics targeting specific cyto-kines and their receptors in COPD patients to allevi-ate respiratory symptoms or reduce the risk of acute exacerbations.However,they failed to bring significant clinical benefits.More studies are need-ed to further determine the efficacy of targeted biotherapy for COPD.

Chronic obstructive pulmonary disease (COPD) is the most common chronic airway disease. The current status of treatment based mainly on bronchodilators and ICS is not sufficient for all of COPD patients. Various studies have attempted to use biologics targeting specific cytokines and their receptors in COPD patients to alleviate respiratory symptoms or reduce the risk of acute exacerbations. However, they failed to bring significant clinical benefits. More studies are needed to further determine the efficacy of targeted biotherapy for COPD.
