According to data from pivotal Phase 3 trials (BOREAS and NOTUS), patients with uncontrolled eosinophilic COPD may start to feel improvement in their breathing as early as 2 to 4 weeks after beginning Dupixent, though more significant benefits are typically observed around 12 weeks. While initial relief can be rapid, the full effects of DUPIXENT in reducing flare-ups and improving quality of life develop over several months, with clinical trials lasting up to a year.
