Study Notes
Dupilumab Study on COPD
- Dupilumab significantly reduces exacerbations and improves lung function in adults with uncontrolled chronic obstructive pulmonary disease (COPD) and type 2 inflammation.
Study Details
- The NOTUS study randomized 470 adults with uncontrolled COPD and type 2 inflammation to 300-mg subcutaneous dupilumab or placebo every 2 weeks.
- Study population included adults aged 40-85 years with physician-diagnosed COPD for at least 12 months who had received background triple inhaler therapy.
Results
- Annualized rate of moderate or severe COPD exacerbations was significantly lower (34%) in the dupilumab group than in the placebo group (0.86 vs 1.30, P <.001) at 52 weeks.
- Dupilumab group saw a significantly greater improvement in lung function than the placebo group based on prebronchodilator forced expiratory volume in 1 second from baseline to 12 weeks (least squares mean change of 139 mL vs 57 mL).
- Improvement in lung function was sustained at 52 weeks (least squares mean change of 115 mL vs 54 mL).
- Changes in total score based on the St.George's Respiratory Questionnaire were greater in the dupilumab group than in the placebo group (least squares mean change of 9.8 vs 6.4).
Safety Outcomes
- Safety outcomes were similar between the dupilumab and placebo groups, with approximately 66% of patients in each group reporting adverse events during the 52-week study period.
- Serious adverse events occurred in 13% and 15.9% of dupilumab and placebo patients, respectively.
- Adverse events resulting in death occurred in 2.6% and 1.5%, respectively.
- Most common adverse events were COVID-19, headache, COPD, and nasopharyngitis.

Description
A phase 3 trial, NOTUS, shows dupilumab's effectiveness in reducing exacerbations and improving lung function in adults with uncontrolled chronic obstructive pulmonary disease (COPD) and type 2 inflammation. The data was presented at the ATS 2024 International Conference and published in The New England Journal of Medicine.
