Active clinical trials for "Cystic Fibrosis"

Cystic Fibrosis (CF) is the most common life-threatening genetic condition affecting Australian children. As well as repeated lung infections, children with CF develop insulin deficiency and eventually diabetes. The CF-IDEA trial (Cystic Fibrosis - Insulin Deficiency, Early Action) will determine whether starting insulin treatment before the onset of diabetes (earlier than current practice) will improve the health of children with CF by improving body weight and lung function.

This study will assess the relative bioavailability of ganciclovir from the pro-drug valganciclovir in lung transplant recipients with or without cystic fibrosis. Each patient will receive 900mg valganciclovir daily for the period specified at their center, starting as soon as possible after the transplant. Pharmacokinetic assessments will be made provided that steady-state kinetics of ganciclovir and immunosuppressive drugs have been obtained (>=4 days of drug therapy). Blood samples for pharmacokinetic analysis will be taken up to 24h post-dose on one occasion. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

In some participants 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. Ataluren 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 ataluren can safely increase functional CFTR protein in the cells of participants with CF due to a nonsense mutation.

OBJECTIVES: Determine whether copies of the cystic fibrosis gene (pGT-1) can be delivered to the cells lining the nose of cystic fibrosis patients using cationic liposome (DMRIE/DOPE) mediated gene transfer.

The goal of the study is to examine multiple markers of anthropometrics, body composition, sarcopenia and frailty and compare them to dual energy X-ray absorptiometry (DXA) output, which is considered the current clinical gold-standard tool to measure body composition. The result of this study will provide detailed data regarding the nutrition and body composition within this Cystic Fibrosis population and also provide a baseline evaluation for use of these biomarkers in the future studies including evaluation of nutritional intervention. Further, the study will also include psychosocial and other patient-reported outcomes and medical contributors to understand their contributions to the nutritional failure in the adult advanced lung disease population. Finally, the study will evaluate both established and emerging nutritional and body composition parameters and link them to clinical outcomes in adults with CF across the spectrum of pulmonary function.

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.

Cystic Fibrosis (CF) is a congenital disease secondary to the abnormal function of CFTR. Patients with CF have an alteration of essential fatty acids, Arachidonic Acid (AA) is increased and Docosahexanoic Acid (DHA) is decrease and the ratio ω-6/ ω-3 is elevated, all these alterations stimulated a chronic and bad regulated state of inflammation. For this porpoise, a fase IV trial, multicentric, controlled, double blind, placebo and parallel in patients elder than two months old and randomized to received every day a dietetically supplement with DHA or placebo, will be done during 12 months. The trial has as a principal objective to proved if this long term supplementation could decrease in contrast with placebo.

This study questions whether low-dose ferrous sulfate taken by mouth daily for 6 weeks increases hemoglobin concentration in adult subjects with cystic fibrosis and hypoferremic anemia.

With the use of Non invasive ventilation the patients with cystic fibrosis will have better lung function (FEV1).

Cystic fibrosis (CF) has many health consequences. A reduction in the ability to perform exercise in patients with CF is related to greater death rates, steeper decline in lung function, and more frequent lung infections. However, the physiological mechanisms for this reduced exercise capacity are unknown. The investigators laboratory recently published the first evidence of systemic vascular dysfunction in patients with CF. Therefore, it is reasonable to suspect that the blood vessels are involved with exercise intolerance in CF. This study will look at how 1) blood flow and 2) artery function contribute to exercise capacity in CF.
