I would recommend Denufosol.
They need many more people than the VX protentiator and Denufosol is much closer to being FDA approved.
There will be plenty of people who will enroll for the VX protentiator because of all the press... Denufosol is amazing and has had incredible Phase III results... but because it's in Phase III so many more patients are needed and it's a bit harder to recruit because you have to have an FEV1 > 75%.
But bottomline - involvement in any clinical trial is FANTASTIC. You help yourself and ALL Cfer's by volunteering your time. So thank you, thank you, THANK YOU!
