Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to find out if the combined therapy lumacaftor-ivacaftor affects glycemia in patient with cystic fibrosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single center, open label study. Patients will have 1 visits at the Diabetes Research Center (DRC), or Clinical Research Center (CRC).

The participants will have been previously screened to make sure they are candidates for the study. These patients will be contacted prior to their first visit to discuss enrollment in the study.

At the study visit the participant will come to the CRC or DRC for a research visit. The following will occur at this study visit: informed consent; brief medical history; weight and height; vital signs and blood pressure; blood draw for DNA extraction, A1c and an extra research tube for storage. This will be scheduled at a time that is convenient to the patient.
