The ADSD has been developed by a multidisciplinary team
(involving representatives from 13 pharmaceutical firms, the C-
Path PRO Consortium,PRO consultants,and expert panelists)in
close accordance with the best available standards for PRO
development outlined in the FDA PRO Guidance [13]. Importantly,
extensive involvement of a demographically and clinically
diverse sample of adults and adolescents with asthma via
qualitative research(in the generation and evaluation of content
of the ADSD)has been comprehensively documented.
