Blood Eosinophil Guided Versus Usual Care In The Management Of Mild To Moderate Asthma at Primary Care (BEAM)
Singapore240 participantsStarted 2025-12-03
Plain-language summary
The aim of this study is to evaluate usual care versus biomarker-directed care (using blood eosinophil counts) for the management of asthma patients in primary care setting.
The study hypothesizes that BEC is a valuable biomarker that can guide asthma treatment, and result in reduction in asthma exacerbations, better symptom control and improvement in quality of life compared to usual arm in mild to moderate asthma patients in the primary care setting.
Researchers would compare using blood eosinophil count guided to usual care to see if biomarker-directed asthma treatment and management

What they're measuring
1
Time to first asthma exacerbation requiring hospitalisation
Timeframe: Within 12 months from enrollment
2
Number of asthma exacerbations not requiring hospitalisation
✕. Current use of long-term immunosuppression, LTRA receptor antagonist (Montelukast) and Theophylline or long-term oral steroids
✕. Presence of other known causes of eosinophilia besides asthma (e.g. parasitic infection), based on physician's discretion and investigation as per clinical practice and suspicion
✕. Current use of beta-blocking agents including eye-drops
✕. Use of oral, rectal, or parenteral glucocorticoid within 30 days and/or depot parenteral glucocorticoid within 12 weeks prior to recruitment
✕. Known diagnosis of Chronic Obstructive Pulmonary Disease, Interstitial lung disease or bronchiectasis
✕. Any significant disease or disorder (eg. Cardiovascular, pulmonary other than asthma, gastrointestinal, hepatic, renal, neurological, musculoskeletal, endocrine, metabolic, malignant, psychiatric, major physical impairment) which, in the opinion of the investigator, may either put the patient at risk because of participation in the study, or may influence the results of the study, or the patient's ability to participate in the study
