Active clinical trials for "Cystic Fibrosis"

Rhinosinusitis disorders are often associated with Cystic Fibrosis. They can restrict quality of life enormously and give cause to repeated ENT surgery. The basic defect in CF is a dysfunction of Chloride channels in exocrine glands, leading to retention of secretions and consecutive chronic inflammation with bacterial superinfections. The prospective placebo controlled cross-over study aims at the evaluation of the efficacy of a nasally inhalation of Pulmozyme with respect to mucus retention and resulting inflammation.

In some patients with cystic fibrosis (CF), the disease is caused by a nonsense mutation (premature stop codon) in the gene that makes the cystic fibrosis transmembrane regulator (CFTR) protein. PTC124 has been shown to partially restore CFTR production in animals with CF due to a nonsense mutation. The main purpose of this study is to understand whether PTC124 can safely increase functional CFTR protein in the cells of patients with CF due to a nonsense mutation.

The purpose of this study is to evaluate whether Biaxin (clarithromycin) improves sputum abnormalities, lung function, and overall feeling of well-being in people with cystic fibrosis (CF). Biaxin is an antibiotic commonly used for the treatment of respiratory infections in people who do not have CF, and is sometimes used in CF patients as well. Studies done in a disease called diffuse panbronchiolitis (which is similar to CF) and some preliminary studies that have been done in CF patients suggest that Biaxin might have a beneficial effect on CF sputum in ways unrelated to its antibiotic activity.

The purpose of this study is to determine whether the nasal inhalation of Colistin is effective to decrease the Pseudomonas aeruginosa bacterial count in the nasal lavage fluid.

Previous work demonstrated that inhaled hypertonic saline (HS) reduces exacerbation frequency and improves lung function in adults with cystic fibrosis (CF). It is unclear, however, whether HS will benefit young patients suffering from CF. The investigators propose to further support the concept that HS can benefit children with mild CF lung disease by performing a relatively short, placebo controlled study of HS in 5-12 year olds, using lung function and mucociliary clearance as key outcome measures.

The purpose of this study is to determine whether the safety, tolerability and pharmacodynamics of SB656933 in patients that have cystic fibrosis

The purpose of this study is to test the safety and efficacy of the final commercial formulation of an antioxidant enriched multivitamin supplement in softgel capsule form (AquADEKs) in increasing the plasma levels of certain nutrients and antioxidants in individuals with cystic fibrosis. Hypothesis: An oral antioxidant-rich multivitamin supplement (AquADEKs), which uses a Generally Regarded As Safe (GRAS) molecule to form micelle-like vehicles, will safely increase systemic levels of beta-carotene, coenzyme Q10, and gamma-tocopherol, decrease PIVKA-II levels, while maintaining levels of vitamins A and D in the normal range in persons with CF > 10 years of age.

Acute systemic hyperglycemia causes oxidative stress and a pro-inflammatory response. The pro-inflammatory cytokines induced by hyperglycemia are toxic to islet insulin producing cells, and thus worsen glucose intolerance. Patients with cystic fibrosis (CF) have a high prevalence of CF related diabetes (CFRD) and up to 40% of CF adults develop CFRD. During the prediabetic phase in CF, there is progression from normal glucose homeostasis to high risk prediabetes characterized by episodes of acute hyperglycemia after meals and during respiratory exacerbations. The mild hyperglycemia seen in CF patients with high risk prediabetes following a meal would be expected to induce a degree of systemic inflammation and oxidative stress. These repetitive episodes, if left unchecked, could lead to progression of glucose impairment, worsening severity of oxidative stress and inflammation, and ultimately the development of CFRD, all via hyperglycemia-induced toxicity to beta cells. Furthermore, this process may be accelerated in CF because lung disease and resultant respiratory exacerbations are associated with oxidative stress and inflammation and this will further contribute to beta cell damage. Sitagliptin is a recently approved agent for type 2 diabetes and markedly enhances insulin secretion in the presence of hyperglycemia and has been shown to be effective in preventing postprandial hyperglycemia. The hypothesis to be tested in this project is that sitagliptin will prevent the development of CFRD in CF subjects with high risk prediabetes by blocking postprandial hyperglycemia. The investigators propose a randomized, double-blind, placebo-controlled, multicenter, 15-month longitudinal study in 118 CF subjects with high risk prediabetes to test this hypothesis. Specifically, the investigators aim to show that chronic treatment with sitagliptin: prevents the conversion to diabetes; results in preservation of beta cell function; reduces systemic measures of oxidative stress and inflammation; and slows the rate of progression of lung disease.

The purpose of this study was to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis aged 6 to 11 years who have the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic adenosine monophosphate (AMP)-dependent protein kinase A (PKA) activation.

The purpose of this research study is to determine if multiple doses of two inhaled drugs will help Cystic Fibrosis patients whose lungs are infected with a bacteria called Burkholderia dolosa. The names of these drugs are tobramycin solution for inhalation and amiloride solution for inhalation. Currently, treating patients with Burkholderia dolosa infections is challenging because the bacteria is resistant to antibiotics. Therefore, researchers are looking for drugs which, when taken with an antibiotic, will help the antibiotic to work more effectively.
