Filter by:The purpose of this study is to assess whether inhalation of 7% hypertonic saline (HS) twice daily for 48 weeks improves the lung clearance index by multiple breath nitrogen washout in comparison with inhalation of 0.9% isotonic saline (IS) in preschool children (ages 3 to 5) with cystic fibrosis.
This study compares the lung clearance index (LCI) in cystic fibrosis and healthy children obtained with two different multiple breath nitrogen washout (MBWN2) devices. Each participants will perform the test (LCI) in duplicate on each device.
The purpose of this study is to determine antimycobacterial drug pharmacokinetics (PK) and pharmacodynamics (PD) in patients with cystic fibrosis (CF) to improve treatment of nontuberculous mycobacterial (NTM) lung disease.
This study compares the lung clearance index (LCI) in cystic fibrosis and healthy adults obtained with two different multiple breath nitrogen washout (MBWN2) devices. Each participants will perform the test (LCI) in duplicate on each device.
Accurate identification of lower respiratory tract pathogens is standard of care in the management of CF patients and it is therefore recommended to perform regular bacterial cultures, at least once a year, but some even recommend monthly cultures. This can be done through different methods, of which sputum and bronchoalveolar lavage (BAL) are the gold standard. However, BAL is an invasive method, not designated to repeat monthly. Therefore, the diagnosis of lower respiratory tract infections can be challenging in the non-expectorating CF patient. Other methods, such as induced sputum (IS), cough swabs and nasal swabs, have been developed to obtain bacterial cultures in these patients. Studies have investigated the reliability of these different sampling methods, however, with controversial conclusions.

The widespread neonatal detection of cystic fibrosis in France since 2002 permits to treat children from birth. New treatments used for young children involve to assess efficacy criteria specific to this population. Standard respiratory function criteria for older children and adults is forced expiratory volume/second. This technique is not suited for preschool aged children (3 to 6 years old) because they are too old to be sedated and too young and immature to be able to make forced expiration technique that are correct, reproducible and prolonged during more than 1 second. For preschool aged children, in order to assess distal damage and her consequence, the evaluations are: airway resistance by debit interruption technic (Rint), plethysmographic measure of specific resistance (sRaw), functional residual capacity by Helium dilution technique (CRF He), arterial blood gas measurement, pulmonary clearance index. All these methods have a better success rate and can be used in alternative or with forced spirometry. However, each of them gives only a part of information on airway and lung damage of detected children. It is necessary to combine them for a better information on overall respiratory damage. In France, each respiratory function test laboratory uses one or any of these methods in addition to flow-volume curve, in function of his practices and his equipment. So, respiratory function test of preschool aged children is going to diversify more and more to the detriment of an homogeneity of practices between different centers. A referent population during a longitudinal multicenter monitoring on large cohorts that describe the evolution of pulmonary function, obtained by a standardized methodology is necessary to assess the efficacy of any new treatment. And, with the homogenization of care of children detected of cystic fibrosis in different centers, the description of natural evolution of pulmonary function by a standardized methodology will improve the discriminative power of measure of respiratory function to assess the presence of a worsening in preschool-aged children.
The purpose of this study is to assess the efficacy of IV gallium to improve pulmonary function as measured by a 5% or greater relative improvement in forced expiratory volume in one second (FEV1) from baseline to Day 28. Funding Source - FDA OOPD
This is a Phase 3, randomized, double blind, placebo controlled, parallel group, multicenter study in people with cystic fibrosis (CF) who are homozygous for the F508del CF transmembrane conductance regulator (CFTR) gene mutation.
The goal of the study is to evaluate the safety and tolerability of P-1037 and to determine whether the combination of P-1037 with hypertonic saline or P-1037 alone has a greater effect on lung function in patients with CF than placebo (0.17% saline).
