New Treatment Option for People With Cystic Fibrosis

(BPT) – <em>For patients with cystic fibrosis (CF) 12 years and older with certain mutations</em>

At 17 years old, Taylor Brown is a straight-A student balancing a 10-hour work week and competitive dancing. She is also one of approximately 30,000 Americans living with cystic fibrosis (CF), a progressive genetic disease that makes it difficult to breathe<sup>i</sup>.

Taylor has been taking a combination of medicines to treat and manage her disease since her diagnosis when she was six days old. In the U.S., approximately 1,000 people are diagnosed with CF each year<sup>i</sup>. CF is a disease you are born with.

“Cystic fibrosis has always been a part of my life, but I don’t let it define me,” said Taylor. “I’m still able to do the things I love, like competitive dancing and advocating for other people with cystic fibrosis.”

There is no cure for the life-shortening disease, but therapies are available for some people that target the underlying cause of CF<sup>ii</sup>. CF is caused by a reduction in the quantity and/or function of cystic fibrosis transmembrane conductance regulator (CFTR) proteins resulting from gene mutations that leads to the buildup of mucus in organs, such as the lungs<sup>i</sup>.

After talking with her treatment team and family, Taylor participated in a clinical trial for SYMDEKO™ (tezacaftor/ivacaftor and ivacaftor). SYMDEKO was recently approved by the Food and Drug Administration (FDA) for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have two copies of the <em>F508del</em> mutation or who have at least one mutation in the CF gene that is responsive to SYMDEKO.

“SYMDEKO is a new treatment option that helps the body’s CFTR proteins work better,” said Patrick Flume, M.D., Director of the Cystic Fibrosis Program at the Medical University of South Carolina. “Scientific innovations have enabled medicines to target cystic fibrosis at its root. I encourage patients and their families to work with their doctors to understand how these developments may help them.”

SYMDEKO is made up of two medicines that work to help increase the quantity and function of CFTR protein in certain people with CF. The FDA approval of SYMDEKO was based on results from two global Phase 3 trials in approximately 750 patients, which demonstrated the safety and efficacy of SYMDEKO in people with CF ages 12 and older who had certain mutations in the <em>CFTR</em> gene.

“I’m excited about new discoveries and research in cystic fibrosis, because they have a very real impact on my life and the lives of others with cystic fibrosis,” said Taylor.
