OBJECTIVE: Add-on therapy with monoclonal antibodies is the recommended therapy for severe asthmatic patients refractory to maintenance treatment. In randomized control trials, mepolizumab reduced the number of exacerbations, the need of oral corticosteroids (OCS), increased asthma control, and lung function in a population of uncontrolled severe eosinophilic asthmatic patients. In this piece of work, we aimed to assess mepolizumab efficacy and safety in a cohort of patients with severe eosinophilic asthma in real-life conditions.
METHODS: A retrospective study was carried out at eight hospitals from Asturias (Spain). The sample included patients treated with mepolizumab from 1 January 2016 to 31 March 2019. Demographic and clinical variables were collected, including OCS use, asthma control, lung function, and exacerbation rate.
RESULTS: Sixty-nine patients (72% women) with mean age 56 ± 13 years were included. Annual exacerbation rate decreased from 4.7 (SD 3.7) to 1.3 (SD 2.5) (p < 0.001). The number of patients requiring OCS treatment decreased from 25 patients (36%, mean prednisone dose = 18 mg/day) to 13 patients (19%, mean prednisone dose = 9 mg/day) (p < 0.001). Twelve patients (48%) stopped OCS treatment. Forced expired volume in one second (FEV1) as percentage increased from 68% (SD 20) to 76% (SD 21) (p < 0.001). Fifty-six patients (81%) were considered responders to mepolizumab. No serious adverse events were detected during the study period.
CONCLUSIONS: Overall, this study demonstrates mepolizumab efficacy and safety in a cohort of patients with uncontrolled severe eosinophilic asthma in routine clinical practice.
