Cystic FibrosisThis study will evaluate the efficacy, safety and pharmacodynamics of elexacaftor (ELX, VX-445) in triple combination (TC) with tezacaftor (TEZ) and ivacaftor (IVA) in subjects with cystic fibrosis (CF) who are heterozygous for F508del and a gating or residual function mutation (F/G and F/RF genotypes).
Aztreonam Lysine for Pseudomonas Infection Eradication Study
Cystic FibrosisThis is an open-label, multi-center study in pediatric patients age 3 months to less than 18 years with cystic fibrosis (CF) and newly detected Pseudomonas aeruginosa (PA) pulmonary colonization/infection. All eligible participants will be treated with a 28-day course of Aztreonam for Inhalation Solution (AZLI) 75 mg 3 times daily. After completion of study drug, subjects will be followed up through Day 196 for safety and recurrence of PA. The primary objective is to evaluate the proportion of participants with PA-negative cultures at all time points during a 6-month monitoring period (through Day 196) after cessation of AZLI treatment. Microbiological cultures will be obtained at Baseline, Day 28 (end of AZLI treatment), Day 56 (1 month after completing AZLI treatment), Day 112 (3 months after completing AZLI treatment), and Day 196 (6 months after completing AZLI treatment).

Study of the Effect of VX-770 on Hyperpolarized Helium-3 Magnetic Resonance Imaging in Subjects...
Cystic FibrosisCystic Fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The encoded protein, CFTR, is an epithelial chloride ion channel responsible for aiding in the regulation of salt and water absorption and secretion in various tissues. Although the disease affects multiple organs, the leading cause of mortality is the progressive loss of lung function. Obstruction of airways with thick mucus, chronic bacterial infection of the airways, and inflammatory response are all thought to play a role in causing lung damage. Through its function as a chloride channel, CFTR is believed to be integral in epithelial ion and water transport and hence, maintaining the normal hydration of lung secretions. VX-770 (ivacaftor) is a potent and selective potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR. Based on in vitro studies and pharmacologic, pharmacokinetic (PK), and safety profiles, VX-770 has been selected for clinical development as a possible treatment for patients with CF. Hyperpolarized noble gas magnetic resonance imaging (HG-MRI) is a promising new means of assessing lung function by direct imaging of certain non-radioactive isotopes of an inert noble gas, such as helium or xenon. Through this technique, high-resolution 3-dimensional images of lung ventilation can be obtained in both pediatric and adult patients during a single short breath-hold following inhalation of the gas. This is a 2-part study to evaluate the effect of VX-770 on hyperpolarized helium-3 magnetic resonance imaging (3He-MRI), and to evaluate the safety and efficacy of VX-770 in subjects aged 12 years and older with CF who have the G551D-CFTR mutation. Part A is a single-blind, placebo-controlled study that includes 4 weeks of VX-770 treatment and 4 weeks of placebo treatment. Part B is an open-label, 48 week study of long-term effect of VX 770 on hyperpolarized 3He-MRI.
Comparison of Airway Clearance Therapy in Cystic Fibrosis Using the Same VEST Therapy Device But...
Cystic FibrosisOur primary hypothesis is that airway clearance therapy with sine waveform HFCWO using higher inflation pressures combined with both low and high oscillator frequencies will result in greater sputum production compared to sine waveform HFCWO with lower inflation pressures and mid-frequency oscillations.
Comparison of Antibiotics for Pseudomonas in Early CF
Cystic FibrosisThis is a prospective, randomized clinical trial comparing the effects of these 2 modes of antibiotic treatment on BALF inflammation in young, P. aeruginosa-positive CF patients.
Mannitol Dose Response Study in Cystic Fibrosis
Cystic FibrosisMany cystic fibrosis patients die of lung failure caused by repeated lung infections from thick, sticky mucus. Past studies have shown Bronchitol inhalation may help to facilitate the clearance of mucus by altering its rheology and replenishing the airway surface liquid layer in these patients, thereby enhancing the shift of stagnant mucus from the lungs. The study aim is to determine the optimal dose of mannitol to generate clinical improvement in patients with cystic fibrosis.
