Active clinical trials for "Cystic Fibrosis"

The primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.

The purpose of this study is to determine whether correction of low nighttime oxygen (O2) levels and/ or high carbon dioxide levels in patients with cystic fibrosis improves their quality of life. The treatments being used overnight are (1)O2 (2)pressurised air which assists breathing (non-invasive positive pressure ventilation, NIPPV)

The purpose of this study was to evaluate the safety and efficacy of a 28-day course of aztreonam for inhalation solution (AZLI) in patients with cystic fibrosis (CF) and lung infection due to Pseudomonas aeruginosa (PA).

Cystic Fibrosis (CF) is the most common lethal genetic disorder in America. Previous studies by our group and others have shown that human recombinant growth hormone (GH) improves height velocity, weight velocity, lean body mass (LBM) and pulmonary function. These positive results have prompted us to ask further questions regarding GH use in CF including: a) Do patients with better baseline body weight and pulmonary function derive more benefit from treatment than those with worse weight and pulmonary function?, b) Does GH use improve the patient's quality of life?, c) Once GH is discontinued, are the positive effects sustained? We hypothesize that GH treatment in CF patients will improve their clinical status and their quality of life. We further hypothesize that these effects will be present regardless of baseline body weight or pulmonary function, and that positive outcome will be sustained for at least one year after GH treatment is discontinued. To test our hypothesis, we will recruit 40 prepubertal children from five CF centers across the United States (8 per center). Patients will be randomly assigned to receive treatment with GH (0.3mg/kg/wk) during either the first or the second year. All subjects will be seen every three months. We will evaluate the following parameters every three months: 1) height, height velocity and Z-score, 2) body weight and weight velocity. Every six months we will measure: 1) lean body mass utilizing DEXA, 2) pulmonary function, including measurement of respiratory muscle strength (peak inspiratory and peak expiratory pressure), 3) quality of life (QOL), quantitated from QOL forms specific for CF ("The Cystic Fibrosis Questionnaire"). After one year of study, subjects will "cross-over" to the other treatment arm. This 24 month study will allow us to statistically compare outcome measures in 20 treated and 20 nontreated subjects from multiple centers, and will allow us to assess sustained effect in the 20 subjects who receive GH during the first year, by comparing their results to results obtained during the year post treatment.

OBJECTIVES: I. Determine the effect of different doses of ibuprofen on neutrophil (polymorphonuclear leukocyte; PMN) delivery to a mucosal surface (the oral mucosa) in patients with cystic fibrosis and healthy controls. II. Determine the duration of effect (and possible rebound effect) of ibuprofen on PMN delivery to a mucosal surface in these patients.

The purpose of this study is to assess the safety and effectiveness of multiple dosages of INS37217 compared to placebo over 28 days in subjects with mild to moderate cystic fibrosis (CF) lung disease. Study drug will be administered through a nebulizer (a device that delivers medication as a mist by breathing it in).

Measured outcomes for people with CF have improved dramatically over the last 20 years, even prior to the widespread introduction of cystic fibrosis transmembrane conductance regulator (CTFR) modulator treatments. The outlook for children with CF has improved significantly, with longer predicted survival and a lower likelihood of morbidity. This has accelerated recently. These changes have occurred within a short period of time, and there is much that we now do not understand about disease progression in children with CF and how this differs from children without CF. CF is an area which is fortunate to have well-developed and successful disease registries. CF registries have provided significant amounts of very useful data to guide improvement in treatment and outcomes over many decades. The power of registries comes from the collection of a well-defined set of important outcome measures in very large numbers of people over many years. The outcome measures collected routinely in clinical care, which form part of the registries, are helpful in monitoring moderate-advances and symptomatic disease in people with CF. CF registries however do not tend to collect tomography(CT) scores, lung clearance index(LCI) or indeed repeated collection of biomarkers of disease activity such as sweat chloride which are increasingly relevant in an era of modulator therapies and reducing burden of symptomatic disease. We perceive an urgent need to complement registry data, cataloguing the changing natural history if early childhood CF by proactively collecting and curating sensitive, meaningful outcome data in a large cohort of children during this new era in Ireland and the UK. The prevalence, presentation and natural history of disease manifestation of CF in young children will change significantly in the next decade with advances in the understanding and treatment of CF, including the use of therapies aimed at CFTR function. ENHANCE provides an opportunity to study these changes in real-time and in ways that are relevant to the CF community.

This research is being done to learn more ways to treat non-respiratory symptoms in people with CF including fatigue, pain, mood, sleep problems and the use of a wellness program to treat them.

This is a Phase 2 open label study to evaluate the safety, tolerability, PK, and PD of multiple dose levels of SC administered ELX-02 with and without ivacaftor in patients with CF with at least one G542X allele or phenotypically similar nonsense allele. Up to 16 patients will be enrolled in the trial; up 4 patients will be homozygotes to G542X, and the remaining patients will be compound heterozygotes with G542X or phenotypically similar nonsense mutation and any Class 1 or Class 2 mutation. Each patient will receive 5 escalating doses as follows: 0.3 mg/kg per day SC 0.75 mg/kg per day SC 1.5 mg/kg per day SC An individualized dose, as high as 3.0 mg/kg per day SC, based upon the patients observed safety and tolerability, PK at previous doses and the results of laboratory tests ELX-02 1.5 mg/kg per day SC plus 150 mg ivacaftor every 12 bid

This 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 homozygous for F508del.
