Hi Elizabeth! We started the TIGER-2 Phase 3 Denufosol trial in June of 2008 when DD was 5. I don't know if we were on the placebo or not. Then we began the open-label extension in July of 2009 so we know we are on the drug. Clinically, we are steady or slightly improved on PFT's, weight, etc.
We have our final visit next week and I think they are going to continue to do the open-label extension.
One advantage has been that Denufosol replaced Hypertonic Saline, which DD absolutley hated, so that has been a huge plus. Also she has gained lots of extra practice blowing PFT's.
The disadvantages have been lots of blood draws <img src="i/expressions/face-icon-small-sad.gif" border="0"> and that 3-times-a-day thing you mentioned! We had previously only done breathing treatments in the morning and the evening so the middle of the day was (and is) tough. (I'm sure I sound like a big whiner to many of you!)
But we are glad to be in it, and would do it again. I hope you also have a good experience.
