Background:This trial aimed to evaluate the efficacy and safety of roflumilast for treating Chinese patients with chronic obstructive pulmonary disease (COPD).Methods:A total of 120 patients with COPD were recruited and were randomly divided into 2 groups (an intervention group and a placebo group) at a 1:1 ratio. Patients received either roflumilast or placebo 500 μg once daily for a total of 12 months. The primary outcome was lung function, measured by the change from baseline of forced expiratory volume in 1 second (FEV1), FVC = forced vital capacity (FVC), and FEF25–75%. The secondary outcome measurements included the quality of life, measured with the St. George's Respiratory Questionnaire (SGRQ). All outcomes were measured at the end of 12-month treatment and 3-month follow-up after the treatment. In addition, adverse events (AEs) were also recorded during the treatment period.Results:FEV1, FVC, FEF25–75%, and SGRQ were significantly better in the intervention group than those in the placebo group at the end of 12-month treatment and 3-month follow up after treatment. Moreover, AEs were much higher with roflumilast than placebo in this study.Conclusions:The findings suggest that roflumilast has promising effect to improve lung function in Chinese population with COPD.
