*Clinical data exists for these mutations. See Clinical studies.

Complex/compound mutations. Most people with CF have 2 CF mutations, 1 on each copy of the CF gene. However, in rare instances, 1 copy of the CF gene can have more than 1 mutation. This is called a compound, or complex, mutation.


Talk to your doctor to learn if you have an indicated CF gene mutation.

It is not known if KALYDECO is safe and effective in children under 4 months of age.

Keep in mind that not all mutations were evaluated in clinical studies, and those that were evaluated were not studied in all age groups. However, KALYDECO is approved for people age 4 months and older with any of the 97 indicated mutations listed above.
