About the treatment
Dupilumab is an add-on maintenance PBS listed treatment for people with severe uncontrolled eosinophilic asthma or severe allergic asthma (aged 12 years and older). Dupilumab is also indicated and PBS-subsidised as maintenance therapy for people with oral corticosteroid dependent eosinophilic or allergic asthma, or chronic severe atopic dermatitis. It is also indicated for patients with chronic rhinosinusitis with nasal polyposis.
Dupilumab has demonstrated efficacy in reducing annualized exacerbation rates and the rate of severe exacerbations leading to hospitalizations and/or emergency department visits (2, 3). Additionally, significant increases in pre-bronchodilator FEV1 have been observed in clinical trials evaluating dupilumab (2, 3). Improvements in FEV1 were similar whether patients were receiving medium dose inhaled corticosteroids, high dose inhaled corticosteroids, or oral corticosteroids. Improvements in asthma control and asthma related quality of life have also been observed (2, 3). In regards to oral corticosteroid reduction, treatment with dupilumab has demonstrated greater reductions in daily maintenance oral corticosteroid dose, while maintaining asthma control, compared to placebo (4).
