Dupixent Approved for COPD Add On
FDA has approved Sanofi and Regeneron’s Dupixent (dupilumab) as an add-on maintenance treatment for adults with inadequately controlled chronic obstructive pulmonary disease (COPD) and an eosinophilic phenotype.
Approval is based on data from two landmark pivotal Phase 3 studies (BOREAS and NOTUS) that evaluated the efficacy and safety of Dupixent compared to placebo in adults currently on maximal standard-of-care inhaled, according to the companies. They say that patients in the studies who received Dupixent saw the following:
- 30% and 34% reduction in the annualized rate of moderate or severe COPD exacerbations at Week 52, the primary endpoint
- 74mL and 68mL improvements in post-bronchodilator forced expiratory volume (FEV1) from baseline at Week 12 compared to placebo
- 51% response in health-related quality of life measures in both trials compared to 43% and 47% with placebo at Week 52
Monoclonal antibody Dupixent works by inhibiting the signaling of the IL-4 and IL-13 pathways, according to the companies. It’s currently approved for treating atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis, and prurigo nodularis.
