"As complications related to CF can occur early in life, we believe it
is important to begin treatment as early as possible and this
supplemental New Drug Application for approval of ORKAMBI in children as
young as six is an important step in that direction," said
The sNDA is based on data from an open label Phase 3 clinical safety
study of ORKAMBI. Data from this study will be presented at the 39th

About CF and ORKAMBI
Cystic fibrosis is a rare genetic disease that is caused by defective or missing cystic fibrosis transmembrane conductance regulator (CFTR) proteins resulting from mutations in the CFTR gene. The defective or missing proteins result in poor flow of salt and water into or out of the cell in a number of organs, including the lungs. In people with two copies of the F508del mutation, the CFTR protein is not processed and trafficked normally within the cell, resulting in little to no CFTR protein at the cell surface. Patients with two copies of the F508del mutation are easily identified by a simple genetic test.
ORKAMBI is a combination of lumacaftor, which is designed to increase the amount of mature protein at the cell surface by targeting the processing and trafficking defect of the F508del CFTR protein, and ivacaftor, which is designed to enhance the function of the CFTR protein once it reaches the cell surface. ORKAMBI is taken every 12 hours - once in the morning and once in the evening with fat-containing food.
INDICATION AND IMPORTANT SAFETY INFORMATION FOR ORKAMBI® (lumacaftor/ivacaftor) TABLETS
ORKAMBI is a prescription medicine used for the treatment of cystic fibrosis (CF) in patients age 12 years and older who have two copies of the F508del mutation (F508del/F508del) in their CFTR gene. ORKAMBI should only be used in these patients. It is not known if ORKAMBI is safe and effective in children under 12 years of age.
Patients should not take ORKAMBI if they are taking certain medicines or herbal supplements, such as: the antibiotics rifampin or rifabutin; the seizure medicines phenobarbital, carbamazepine, or phenytoin; the sedatives/anti-anxiety medicines triazolam or midazolam; the immunosuppressant medicines everolimus, sirolimus, or tacrolimus; or St. John's wort.
Before taking ORKAMBI, patients should tell their doctor if they have or have had liver problems or have kidney problems; have had an organ transplant; are using birth control (hormonal contraceptives, including oral, injectable, transdermal or implantable forms). Hormonal contraceptives should not be used as a method of birth control when taking ORKAMBI; are pregnant or plan to become pregnant because it is unknown if ORKAMBI will harm the unborn baby; are breastfeeding or planning to breastfeed. It is unknown if ORKAMBI passes into breast milk.
ORKAMBI may affect the way other medicines work and other medicines may affect how ORKAMBI works. Therefore, the dose of ORKAMBI or other medicines may need to be adjusted when taken together. Patients should especially tell their doctor if they take: antifungal medicines such as ketoconazole, itraconazole, posaconazole or voriconazole; or antibiotics such as telithromycin, clarithromycin, or erythromycin.
When taking ORKAMBI, a patient should tell their doctor if they stop ORKAMBI for more than 1 week as the doctor may need to change the dose of ORKAMBI or other medicines the patient is taking. It is unknown if ORKAMBI causes dizziness. A patient should not drive a car, use machinery, or do anything requiring alertness until the patient knows how ORKAMBI affects them.
ORKAMBI can cause serious side effects including:
High liver enzymes in the blood, which can be a sign of liver injury, have been reported in patients receiving ORKAMBI. The patient's doctor will do blood tests to check their liver before they start ORKAMBI, every three months during the first year of taking ORKAMBI, and annually thereafter. The patient should call the 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 the skin or the white part of the eyes; loss of appetite; nausea or vomiting; dark, amber-colored urine; or confusion.
Respiratory events such as shortness of breath or chest tightness were observed in patients when starting ORKAMBI. If a patient has poor lung function, their doctor may monitor them more closely when starting ORKAMBI.
An increase in blood pressure has been seen in some patients treated with ORKAMBI. The patient's doctor should monitor their blood pressure during treatment with ORKAMBI.
Abnormality of the eye lens (cataract) has been noted in some children and adolescents receiving ivacaftor, a component of ORKAMBI. For children and adolescents, the patient's doctor should perform eye examinations prior to and during treatment with ORKAMBI to look for cataracts.
The most common side effects of ORKAMBI include: shortness of breath and/or chest tightness; upper respiratory tract infection (common cold), including sore throat, stuffy or runny nose; gastrointestinal symptoms including nausea, diarrhea, or gas; rash; fatigue; flu or flu-like symptoms; increase in muscle enzyme levels; and irregular, missed, or abnormal menstrual periods and heavier bleeding.

About Cystic Fibrosis
Cystic fibrosis is a rare, life-threatening genetic disease affecting approximately 75,000 people in North America, Europe and Australia.
CF is caused by a defective or missing 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, lead
to CF by creating defective or too few CFTR proteins at the cell
surface. The defective or missing CFTR protein results in poor flow of
salt and water into or out of the cell in a number of organs, including
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 predicted age
of survival for a person born today with CF in
