Pivotal Study to Assess the Efficacy, Safety and Tolerability of Dupilumab in Patients With Moderate to Severe COPD With Type 2 Inflammation

Inclusion Criteria

• Participants with a physician diagnosis of COPD who met the following criteria at screening:
• Current or former smokers with a smoking history of ≥10 pack-years.
• Moderate-to-severe COPD (post-bronchodilator FEV1/ forced vital capacity [FVC] ratio 30% and ≤70%).
• Medical Research Council (MRC) Dyspnea Scale grade ≥2.
• Patient-reported history of signs and symptoms of chronic bronchitis (chronic productive cough) for 3 months in the year up to screening in the absence of other known causes of chronic cough.
• Documented history of high exacerbation risk defined as exacerbation history of ≥2 moderate or ≥1 severe within the year prior to inclusion. At least one exacerbation should have occurred while the participant was taking inhaled corticosteroid (ICS)/long-acting beta agonist (LABA)/long-acting muscarinic antagonist (LAMA) (or LABA/LAMA if ICS is contraindicated). Moderate exacerbations were recorded by the investigator and defined as AECOPD that required either systemic corticosteroids (intramuscular, intravenous, or oral) and/or antibiotics. One of the two required moderate exacerbations had to require the use of systemic corticosteroids. Severe exacerbations were recorded by the investigator and defined as AECOPD requiring hospitalization or observation > 24 hours in emergency department/urgent care facility.
• Background triple therapy (ICS + LABA + LAMA) for 3 months prior to randomization with a stable dose of medication for ≥1 month prior to Visit 1; Double therapy (LABA + LAMA) allowed if ICS is contraindicated.
• Evidence of Type 2 inflammation: Participants with blood eosinophils ≥300 cells/microliter at Visit 1.

Exclusion Criteria

• COPD diagnosis for less than 12 months prior to randomization.
• Participants with current diagnosis of asthma according to the Global Initiative for Asthma (GINA) guidelines, or documented history of asthma.
• Significant pulmonary disease other than COPD (e.g., lung fibrosis, sarcoidosis, interstitial lung disease, pulmonary hypertension, bronchiectasis, Churg-Strauss Syndrome etc) or another diagnosed pulmonary or systemic disease associated with elevated peripheral eosinophil counts.
• Cor pulmonale, evidence of right cardiac failure.
• Long-term treatment with oxygen >4.0 L/min OR if a participant requires more than 2.0 L/min in order to maintain oxygen saturation >88%
• Hypercapnia requiring Bi-level ventilation.
• AECOPD as defined in inclusion criteria within 4 weeks prior to screening, or during the screening period.
• Respiratory tract infection within 4 weeks prior to screening, or during the screening period.
• History of, or planned pneumonectomy or lung volume reduction surgery. Participants who were participating in the acute phase of a pulmonary rehabilitation program, ie, who started rehabilitation <4 weeks prior to screening (Note: participants in the maintenance phase of a rehabilitation program can be included).
• Diagnosis of α-1 anti-trypsin deficiency.
