Dupixent Asthma Drug Shows Promise in Treating COPD, Boosting Sanofi and Regeneron Shares

TL;DR
Sanofi and Regeneron's jointly developed asthma drug Dupixent has shown promise in treating COPD patients, according to new data from a phase three clinical trial. The drug reduced bad bouts of chronic obstructive pulmonary disease by 30% compared with a placebo over 52 weeks. Dupixent is already approved for asthma and some skin conditions, but it could become the first new treatment in over a decade for COPD. The trial enrolled COPD patients with type 2 inflammation, and those who received Dupixent showed improvements in lung function, quality of life, and respiratory symptoms. A second phase three trial of Dupixent in COPD is ongoing, with data expected in 2024.
