Kalydeco (kuh-LYE-deh-koh), a new treatment for cystic fibrosis (CF)

You'll hear about Kalydeco (kuh-LYE-deh-koh), a new treatment for cystic fibrosis (CF).

Kalydeco (ivacaftor) is the first drug that treats the underlying genetic mutation that causes CF...not just its symptoms.

Unfortunately, it'll only help the 4% of CF patients who have a rare genetic mutation. But in the future, you'll see drugs that target more common mutations that cause CF.
