Evidence of Reduction in Annual Rate of FEV1 Decline and Sustained Benefits with Lumacaftor and Ivacaftor in Patients with Cystic Fibrosis Homozygous for F508del-CFTR
Abstract #180, Workshop 07: Clinical Advances in
An analysis of 96-week data from the PROGRESS extension study of the pivotal Phase 3 TRAFFIC and TRANSPORT studies of lumacaftor/ivacaftor in people ages 12 and older with two copies of the F508del mutation showed that lumacaftor/ivacaftor was generally well tolerated and had a safety profile consistent with that seen in TRAFFIC and TRANSPORT. In this 96-week safety extension study, all participants received one of two lumacaftor/ivacaftor combination regimens (400mg lumacaftor q12h in combination with 250mg ivacaftor q12h, or 600mg lumacaftor QD in combination with ivacaftor 250mg q12h). Mean lung function, a secondary endpoint of PROGRESS, was maintained above TRAFFIC/TRANSPORT baseline for up to 120 weeks.
An analysis of the rate of lung function decline was also conducted at
week 96 of PROGRESS to compare the results for people who received the
approved commercial dose of lumacaftor (400mg q12h) in combination with
ivacaftor (250mg q12h) (n=455) to a propensity score matched cohort
(n=1,588) of patients from the
The most common adverse events occurring in ≥20 percent of patients in either treatment group were pulmonary exacerbation, cough, sputum increased, hemoptysis, and dyspnea. Mean blood pressure increased from 113.4/68.7 mmHg at baseline of TRAFFIC/TRANSPORT to 118.0/72.8 mmHg at week 96 of PROGRESS in patients continuing lumacaftor 400 mg q12h/ivacaftor and increased from 113.2/68.6 mmHg at baseline of TRAFFIC/TRANSPORT to 119.1/73.5 mmHg at week 96 of PROGRESS in patients who transitioned from placebo to lumacaftor 400 mg q12h/ivacaftor.
"These data suggest that the benefits of lumacaftor/ivacaftor are
sustained through 96 weeks and indicate that the medicine may modify the
progression of CF lung disease by treating its underlying cause," said
Safety, Tolerability, and Pharmacodynamics of Combination Lumacaftor/Ivacaftor Therapy in Patients Aged 6-11 years with CF Homozygous for the F508del-CFTR mutation
Abstract 179; Workshop 07: Clinical Advances in
Final data from an open-label Phase 3 safety study that evaluated
ORKAMBI in children with CF ages 6 through 11 who have two copies of the F508del
mutation showed that lumacaftor/ivacaftor was generally well tolerated.
The primary endpoint was safety. No new safety events were observed
compared to older patients. Respiratory events (dyspnea, wheezing,
respiration abnormal) were infrequent and not associated with any
discontinuations. In the study, all children received a twice-daily
fixed-dose combination of lumacaftor (200mg) and ivacaftor (250mg) for
24 weeks. These data supported the recent
Long-term Safety and Efficacy of Ivacaftor in Pediatric Patients Aged 2-5 years with CF and a CFTR Gating Mutation
Abstract 177; Workshop 07: Clinical Advances in
Data from the KLIMB and KIWI studies of ivacaftor in children ages 2 through 5 with CF and a CFTR gating mutation showed that ivacaftor demonstrated a durable safety profile for a total of 108 weeks of continuous treatment. Sweat chloride reductions in the 24-week open label Phase 3 KIWI study were maintained through KLIMB, an 84-week open-label extension study. Age-normalized growth parameters were either maintained or improved from KIWI baseline through KLIMB. The most common adverse event of any grade was cough. Elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels > 3x the upper limit of normal (ULN) were reported in ten out of 33 patients. Of these ten, four had elevated ALT/AST levels of > 8x ULN in KIWI. Ivacaftor was maintained or resumed in all but one patient who discontinued and elevated ALT/AST levels resolved upon discontinuation.
About the Rate of Lung Function Decline Analysis
PROGRESS is the 96-week extension study of TRAFFIC and TRANSPORT, the
pivotal 24-week Phase 3 studies of ORKAMBI in people ages 12 and older
with two copies of the F508del mutation. For the rate of lung
function decline analysis, a propensity score approach was used to match
patients from PROGRESS to patients from the
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 6 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 6 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; 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. Patients should tell their doctor if they are pregnant or plan to become pregnant (it is unknown if ORKAMBI will harm the unborn baby) or if they 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, patients 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. Patients 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 ORKAMBI and 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 is 41 years, but the median age of death is 27 years.
