In Study 5

  • KALYDECO® was studied in 69 people with CF age 6 years and older with an R117H mutation in the CF gene. These people took KALYDECO or placebo every 12 hours with fat-containing food for 24 weeks

  • Change in lung function was the main endpoint, or measure, of this study
    • Lung function was measured in a test called FEV1, or forced expiratory volume exhaled in 1 second
  • Other endpoints included change in sweat chloride, change in CF respiratory symptoms (such as cough, mucus production, and trouble breathing), change in body mass index (BMI), time to first pulmonary exacerbation, and safety
    • BMI is a measure of a person’s weight relative to height
    • Pulmonary exacerbation is any new, or change in, antibiotics that people had to take because of 4 or more symptoms involving their sinuses or lungs
  • People in this study kept taking their other CF therapies

Some people in this study showed improvement in these endpoints, but others did not

  • Please talk to your healthcare provider to learn more about the results of this study
