Study Title: G551D Observational Study- Expanded to Additional Genotypes and Extended for Long Therm
Follow up (GOAL-e2)
Study Purpose (2-3 sentences in laymen terms):
The goal of this research study is to collect blood and urine samples from people who have either the
R117H type of CF or the non-G551D gating type of CF to be kept for future research.We will also use some
of the collected blood to measure the number of neutrophils.
Study Summary (1 paragraph in laymen terms):
Detailed Description:

Blood Collection: Blood will be collected to be kept for research in the future and to measure the
number of blood cells called neutrophils. A small needle will be used to collect blood from a vein in
your arm. About 7-9 teaspoons of blood would be collected.

Sweat Collection: Your sweat will be collected with a special sweat collection machine to test the
amount of salt in your sweat.

Spirometry: You will be asked to take a test that measures how well your lungs are working. You
will be asked to take a deep breath and then blow into a mouthpiece as hard as possible and for as
long as possible. This is the same test that is done when you come to clinic.

Urine Collection: Urine will also be collected to be kept for research in the future. You will be asked
to pee in a cup.

Medical Information: We are asking you to share your medical information with study researchers.
Your medical information will not contain any of your personal identification information, like your
name and address.
Optional:
• Induced Sputum Collection: If you say "yes" to collecting a sputum sample, you will be asked to breathe in
a salt water solution to help you cough out sputum. If you cannot breathe in the salt water solution to
cough out sputum for the last study visit, you will be asked to cough mucus into a cup
