Efficacy
MORE I CAN MOMENTS for eligible patients who continue to experience exacerbations on triple inhaled therapy, or double inhaled therapy if ICS is not appropriate.
A breakthrough therapy in COPD1
MORE I CAN MOMENTS with reduced exacerbations1
DUPIXENT + SOC consistently and significantly (P<0.001) reduced the annualised rate of moderate or severe COPD exacerbation rates in patients with uncontrolled COPD and type 2 inflammation vs placebo + SOCa,1
Moderate or severe exacerbations are a major contributor to poor outcomes in COPD2
BOREAS and NOTUS clinical trials assessed safety, tolerability and efficacy in COPD patients with Type 2 Inflammation1,3,4
All patients received maximal inhaled therapy SOC (ICS+LAMA+LABA, or LAMA+LABA if ICS was not appropriate)l,1
Two phase 3, multicentre, international, double-blind, randomised, placebo-controlled trials in patients with uncontrolled COPD1,3,4
