He acknowledged certain limitations of the study, including its 6-month duration, which is shorter than most exacerbation studies. “But by recruiting at multiple sites in multiple countries and across seasons, we don’t think this was an importation limitation,” he said. “Of course, like most investigators, I can always think of things I wish I had tracked. My personal hunch is that FeNO [exhaled nitric oxide levels] might offer some useful information but that will be a hunch to explore in another study.”
SUNSET was sponsored by Novartis. Dr. Chapman disclosed that he has received fees for research, consulting and lectures from Novartis, as well as from several other pharmaceutical companies.
