AI Technical Summary
Current treatments are ineffective for COPD patients with a blood eosinophil count of less than 300 cells/μL, especially the triple combination therapy of long-acting muscarinic antagonists, long-acting β2-agonists, and inhaled corticosteroids, which has failed to meet efficacy and safety requirements.
Encerfentin, a PDE3/PDE4 inhibitor, is administered to patients via inhalation. It combines anti-inflammatory and bronchodilatory activities to treat COPD patients with a blood eosinophil count of less than 300 cells/μL.
It significantly reduces the frequency and severity of COPD exacerbations, prolongs the duration of exacerbations, reduces the risk of exacerbations, and provides a safe and effective treatment option.
