Late-breaking data were presented from the NOTUS phase 3 study evaluating the investigational use of Dupixent (dupilumab) as an add-on maintenance treatment in adults with uncontrolled COPD on maximal standard-of-care inhaled therapy (nearly all on triple therapy) and evidence of type 2 inflammation (i.e., blood eosinophils ≥300 cells per μL).

The NOTUS study confirmed the positive results demonstrated in the landmark phase 3 BOREAS study, with its data presented at a late-breaking session of the 2024 American Thoracic Society (ATS) International Conference and simultaneously published in the New England Journal of Medicine (NEJM)

Surya Bhatt, M.D., MSPH, Professor at the University of Alabama at Birmingham, Division of Pulmonary, Allergy, and Critical Care Medicine, and a co-principal investigator of the study, said: “In my more than 20 years of practice, there have been limited advancements for patients struggling with the debilitating effects of uncontrolled COPD, and too many patients experience a vicious cycle of exacerbations that can result in loss of lung function and greatly diminish their quality of life. In NOTUS, dupilumab reduced exacerbations by a magnitude never seen before with an investigational biologic in a phase 3 COPD clinical study. These comprehensive results reinforce that, if approved, dupilumab could provide a first-of-its-kind medical advancement for the COPD community.”

As presented and published, the NOTUS study met its primary and key secondary endpoints.

Dupixent is currently under Priority Review by the US Food and Drug Administration as an add-on maintenance treatment in certain adult patients with uncontrolled COPD with evidence of type 2 inflammation. The target action date is June 27, 2024. Regulatory submissions are also under review in the European Union and China, and discussions with other regulatory authorities around the world are ongoing.

The potential use of Dupixent in COPD is currently under clinical development, and its safety and efficacy have not been fully evaluated by any regulatory authority in this setting.
