-- Additional KALYDECO™ (ivacaftor) and CF pipeline presentations highlight Vertex's commitment to advancing CF treatment by targeting the underlying cause of the disease --
"These study results are an exciting step for the cystic fibrosis community, and we look forward to the start of this pivotal program early next year," said Dr. Boyle. "We are particularly encouraged to make such important progress in efforts to treat the underlying cause of the disease in people with two copies of the F508del mutation, who account for the single largest group of people with CF."
Shortly after Dr. Boyle's presentation, the slides will be available on
the NACFC-Handout Hub website at: http://nacfcdl.cff.org/Pages/library.aspx.
Vertex will also host a webcast today,
Updates to Vertex's
For more than 14 years, Vertex has been working to develop new medicines
to treat the underlying cause of CF in as many people as possible. CF is
caused by defective or missing CFTR proteins resulting from mutations in
the CFTR gene. Earlier this year, Vertex received regulatory
Vertex's ongoing work in CF includes additional studies of ivacaftor monotherapy in patients who may benefit from improved CFTR protein function; the evaluation of a combination of a CFTR corrector and the CFTR potentiator, ivacaftor, in patients with the F508del mutation; and continued research aimed at discovering additional potential medicines that could be evaluated as part of future combination treatments. Vertex has multiple studies planned and underway to support these goals, and the company today provided the following updates:

KALYDECO™ (ivacaftor) is the first treatment to target the underlying
cause of CF in people with the G551D mutation in the CFTR gene.
Known as a CFTR potentiator, KALYDECO is an oral medicine that aims to
help the CFTR protein function more normally once it reaches the cell
surface, to help hydrate and clear mucus from the airways. KALYDECO
(150mg, q12h) was first approved by the

Indication and Important Safety Information for KALYDECO™ (ivacaftor)
KALYDECO (150mg tablets) is indicated for the treatment of cystic fibrosis (CF) in patients age 6 years and older who have a G551D mutation in the CFTR gene.
KALYDECO is not for use in people with CF due to other mutations in the CFTR gene. It is not effective in CF patients with two copies of the F508del mutation (F508del/F508del) in the CFTR gene.
High liver enzymes (transaminases, ALT and AST) have been reported in patients receiving KALYDECO. It is recommended that ALT and AST be assessed prior to initiating KALYDECO, every 3 months during the first year of treatment, and annually thereafter. Patients who develop increased transaminase levels should be closely monitored until the abnormalities resolve. Dosing should be interrupted in patients with ALT or AST of greater than 5 times the upper limit of normal. Following resolution of transaminase elevations, consider the benefits and risks of resuming KALYDECO dosing. Moderate transaminase elevations are common in subjects with CF. Overall, the incidence and clinical features of transaminase elevations in clinical trials was similar between subjects in the KALYDECO and placebo treatment groups. In the subset of patients with a medical history of elevated transaminases, increased ALT or AST have been reported more frequently in patients receiving KALYDECO compared to placebo.
Use of KALYDECO with medicines that are strong CYP3A inducers such as the antibiotics rifampin and rifabutin; seizure medications (phenobarbital, carbamazepine, or phenytoin); and the herbal supplement St. John's Wort substantially decreases exposure of KALYDECO, which may diminish effectiveness. Therefore, co-administration is not recommended.
The dose of KALYDECO must be adjusted when concomitantly used with potent and moderate CYP3A inhibitors.
KALYDECO can cause serious adverse reactions including abdominal pain and high liver enzymes in the blood. The most common side effects associated with KALYDECO include headache; upper respiratory tract infection (the common cold), including sore throat, nasal or sinus congestion, and runny nose; stomach (abdominal) pain; diarrhea; rash; and dizziness. These are not all the possible side effects of KALYDECO. A list of the adverse reactions can be found in the full product labeling for each country where KALYDECO is approved. Patients should tell their healthcare providers about any side effect that bothers them or doesn't go away.
About Cystic Fibrosis
Cystic fibrosis is a rare, life-threatening genetic disease affecting
approximately 30,000 people in
CF is caused by defective or missing CFTR proteins resulting from mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF. There are more than 1,800 known mutations in the CFTR gene. Some of these mutations, which can be determined by a genetic, or genotyping test, lead to CF by creating non-working or too few CFTR proteins at the cell surface. The absence of working CFTR proteins results in poor flow of salt and water into and out of the cell in a number of organs, including the lungs.

About the Cystic Fibrosis Foundation
The Cystic Fibrosis Foundation is the world's leader in the search for a cure for cystic fibrosis. The Foundation funds more CF research than any other organization and nearly every CF drug available today was made possible because of Foundation support. Based in Bethesda, Md., the Foundation also supports and accredits a national care center network that has been recognized by the National Institutes of Health as a model of care for a chronic disease. The CF Foundation is a donor-supported nonprofit organization. For more information, visit www.cff.org.
Vertex creates new possibilities in medicine. Our team discovers, develops and commercializes innovative therapies so people with serious diseases can lead better lives.
Vertex scientists and our collaborators are working on new medicines to cure or significantly advance the treatment of hepatitis C, cystic fibrosis, rheumatoid arthritis and other life-threatening diseases.

limitation, Dr. Boyle's statements in the second paragraph of this press
release, Dr. Mueller's statements in the tenth paragraph of this press
release and statements regarding (i) Vertex's commitment to advancing CF
treatment by targeting the underlying cause of the disease, (ii)
Vertex's ongoing and planned clinical trials of ivacaftor alone and in

VX-809 in combination with ivacaftor and (iii) Vertex's ongoing research

While Vertex believes the forward-looking statements contained in this
press release are accurate, there are a number of factors that could
cause actual events or results to differ materially from those indicated
