deal of benefit to your overall health. Lastly, it is not clear how long any genetic changes 
to your lung cells will last. 
It is hoped, however, if the results of this trial are positive, that the use of this gene transfer 
virus might be expanded to make it clinically effective. Your participation in this study 
neither guarantees nor excludes the possibility of your being included in subsequent 
studies. 
For outpatient visits, you will be paid $50 per visit, and will have free parking provided. 
Neither you nor your insurance company will be charged for any tests, procedures, or 
hospital admissions involved in this study. 
ALTERNATIVES TO PARTICIPATION: 
If you choose not to participate in this study, your care in the CF center will not be affected 
in any way. Also, your choice about participating in this study will not affect your ability 
to participate in future gene transfer or other research trials for CF therapies.
