FDA Approves KALYDECO® (ivacaftor) as First and Only CFTR Modulator to Treat Eligible Infants with CF as Early as Six Months of Age
-Opportunity to treat the underlying cause of CF earlier than ever before-
-Safety data from Phase 3 ARRIVAL study support treatment with KALYDECO in children ages six to <12 months with eligible mutations-
“Today’s approval for KALYDECO allows physicians to begin treating the
underlying cause of CF in eligible infants as young as six months of age
for the first time, with the potential to modify the course of the
Mean baseline sweat chloride for the children in this cohort was 101.5 mmol/L (n=11). Following 24 weeks of treatment with KALYDECO, the mean sweat chloride level was 43.1 mmol/L (n=6). In the six subjects with paired sweat chloride samples at baseline and week 24, there was a mean absolute change of -58.6 mmol/L (95% CI; -75.9, -41.3).
Results of this study were presented at the 32nd Annual
“The manifestations of CF are often present at birth, which underscores
our relentless commitment to reach the youngest CF patients possible in
our clinical trials,” said
KALYDECO was first approved in 2012 in the U.S. and is now available in more than 40 countries with more than 5,000 patients on therapy. For more information on KALYDECO, prescribing information, or patient assistance programs, visit Kalydeco.com or VertexGPS.com.
About Cystic Fibrosis
Cystic Fibrosis (CF) is a rare, life-shortening genetic disease affecting approximately 75,000 people in
CF is caused by a defective or missing cystic fibrosis transmembrane conductance regulator (CFTR) protein resulting from mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF. There are approximately 2,000 known mutations in the CFTR gene. Some of these mutations, which can be determined by a genetic test, or genotyping test, lead to CF by creating non-working or too few CFTR proteins at the cell surface. The defective function or absence of CFTR protein results in poor flow of salt and water into and out of the cell in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus that can cause chronic lung infections and progressive lung damage in many patients that eventually leads to death. The median age of death is in the mid-to-late 20s.
About KALYDECO® (ivacaftor)
KALYDECO® (ivacaftor) is the first medicine to treat the underlying cause of CF in people with specific mutations in the CFTR gene. Known as a CFTR potentiator, KALYDECO is an oral medicine designed to keep CFTR proteins at the cell surface open longer to improve the transport of salt and water across the cell membrane, which helps hydrate and clear mucus from the airways. KALYDECO is available as 150 mg tablets for adults and pediatric patients age 6 years and older. It is also available as 25 mg, 50 mg and 75 mg granules in pediatric patients ages 6 months to less than 6 years.
People with CF who have specific mutations in the CFTR gene are
currently indicated for KALYDECO in different countries across
INDICATION AND IMPORTANT SAFETY INFORMATION FOR KALYDECO® (ivacaftor)
KALYDECO (ivacaftor) is a prescription medicine used for the treatment of cystic fibrosis (CF) in patients age 6 months and older who have at least one mutation in their CF gene that is responsive to KALYDECO. Patients should talk to their doctor to learn if they have an indicated CF gene mutation. It is not known if KALYDECO is safe and effective in children under 6 months of age.
Patients should not take KALYDECO if they take certain medicines or herbal supplements, such as: the antibiotics rifampin or rifabutin; seizure medications such as phenobarbital, carbamazepine, or phenytoin; or St. John’s wort.
Before taking KALYDECO, patients should tell their doctor if they:
have liver or kidney problems; drink grapefruit juice, or eat grapefruit
KALYDECO may affect the way other medicines work, and other medicines may affect how KALYDECO works. Therefore the dose of KALYDECO may need to be adjusted when taken with certain medications. Patients should especially tell their doctor if they take antifungal medications such as ketoconazole, itraconazole, posaconazole, voriconazole, or fluconazole; or antibiotics such as telithromycin, clarithromycin, or erythromycin.
KALYDECO can cause dizziness in some people who take it. Patients should not drive a car, use machinery, or do anything that needs them to be alert until they know how KALYDECO affects them.
Patients should avoid food containing grapefruit or
KALYDECO can cause serious side effects.
High liver enzymes in the blood have been reported in patients receiving KALYDECO. The patient’s doctor will do blood tests to check their liver before starting KALYDECO, every 3 months during the first year of taking KALYDECO, and every year while taking KALYDECO. For patients who have had high liver enzymes in the past, the doctor may do blood tests to check the liver more often. Patients should call their doctor right away if they have any of the following symptoms of liver problems: pain or discomfort in the upper right stomach (abdominal) area; yellowing of their skin or the white part of their eyes; loss of appetite; nausea or vomiting; or dark, amber-colored urine.
Abnormality of the eye lens (cataract) has been noted in some children and adolescents receiving KALYDECO. The patient’s doctor should perform eye examinations prior to and during treatment with KALYDECO to look for cataracts.
The most common side effects include headache; upper respiratory tract infection (common cold), which includes sore throat, nasal or sinus congestion, and runny nose; stomach (abdominal) pain; diarrhea; rash; nausea; and dizziness.
These are not all the possible side effects of KALYDECO. Please click here to see the full Prescribing Information for KALYDECO.
