Aerosolized Alpha-1 antitrypsin: Phase II/III final data

Additionally, inhaled AAT non-significantly reduced the rate of the first moderate exacerbation event vs. placebo (56.5% vs. 63.9%, p=not significant). In a subgroup of the most frequent exacerbators, inhaled AAT non-significantly reduced the rate of first severe exacerbation events (19.4% vs. 35.2%, p=not significant) and the rate of severe and moderate exacerbation events (44.8% vs. 51.9%, p=not significant) vs. placebo.

In the overall population, inhaled AAT significantly...
