Active clinical trials for "Cystic Fibrosis"

The purpose of the study is to develop new biomarkers for studies of cystic fibrosis (CF). Defects in the gene encoding Cystic Fibrosis Transmembrane Regulator (CFTR) cause CF, an autosomal recessive disorder affecting mainly the pulmonary and digestive tract, leading to early death largely due to progressive loss of pulmonary function. In vitro experiments show that quercetin - a dietary supplement with a well-established safety profile for human use, including clinical trials in a variety of disorders encompassing cancer, heart disease, and as an anti-inflammatory agent - induces activation of CFTR. The nasal potential difference (NPD) test is a measurement of voltage across the nasal membrane and as a fundamental biomarker for CFTR activity in vivo. The NPD is a useful, well-established tool in CF research to determine both diagnoses as well as to measure the effect of new therapies. In vitro experiments show that quercetin induces activation of CFTR additive to that seen with current NPD reagents. In addition, it activates rescued mutant CFTR in vitro (∆F508 CFTR the most common cause of CF), whereas conventional agonists do not. Preliminary in vivo experiments mirrored these results and show that quercetin activates CFTR in human (n=12) NPD tests. Importantly, quercetin perfusion was well-tolerated by a validated sinus questionnaire and physician assessed nasal examination rating. These studies provide strong support for use of quercetin as potentiator of CFTR Cl- channel function by nasal administration. By adding quercetin to the sequence of perfusion solutions for NPD, the investigators may be better suited to detect ∆F508 CFTR activity of rescued mutant protein in the CF patient population.

The purpose of this research study is to test the pharmacokinetics, safety, and tolerability of an intravenous infusion of a drug called Ganite (gallium nitrate) in patients with cystic fibrosis. We want to see this drug is safe and tolerable and to see if high levels of the drug are found in the sputum.

This study is designed to investigate the effect of food on the relative bioavailability of 2 different strengths of fixed-dose combinations of lumacaftor and ivacaftor tablet formulations.

The purpose of this project is to determine the short-term effects of a customized Core Strengthening and Respiratory Exercise Program (CSREP) on children with cystic fibrosis (CF) between the ages of 10 and 21 who are receiving outpatient care at Children's Hospitals and Clinics of Minnesota. The CSREP, which will be provided by a physical therapist and a physical therapist assistant, consists of specific breathing techniques and core strengthening exercises, designed to improve rib cage mobility, pulmonary function, aerobic capacity, posture, and core strength. Currently the CF population at Children's receives physical therapy on an inpatient basis only. The overall goal of this program is to prove the viability of an outpatient exercise program for this population. Specific aims include: To customize a CSREP protocol per each patient To measure patient outcomes at baseline and six months To develop a satisfaction tool in order to measure patient experience and satisfaction

We are testing a new combination of medicines, to determine if they could be used to treat cystic fibrosis (CF). Subjects with CF who have two copies of the most common mutation (change) found in patients with CF called DF508. CF is caused by a lack of chloride movement in the nose, sinuses, lungs, intestines, pancreas and sweat glands. We are conducting this study to determine the safety of using a combination of two medicines, Phenylbutyrate and Genistein, to improve the ability of the cells lining the nose to regulate movement of salt (chloride) and water in people with CF. Phenylbutyrate has been extensively used to treat patients with rare metabolic diseases (which are very different from CF), Phenylbutyrate is an investigational drug for the purpose of this study. Genistein is a naturally occurring substance that is found in food products such as soy and tofu, but is also an investigational drug for this study. Both drugs may be able to restore normal chloride movements in body organs and glands. We will be studying salt and water in the nose movement by a technique called nasal transepithelial potential difference (NPD).

The aim of this study was to examine the effect of the tele-exercise program applied to children with cystic fibrosis in the Covid-19 pandemic on the quality of life and the symptoms experienced during exercise

The purpose of this study is to evaluate the pharmacokinetics (PK) and safety of VX-121/tezacaftor/deutivacaftor (VX-121/TEZ/D-IVA) in participants with moderate hepatic impairment and in matched healthy participants.

This study is a single center, randomized pilot study to evaluate the clinical effectiveness of nasal high flow 20LPM humidification therapy in subjects with Cystic Fibrosis.

The purpose of this actual use human factors (HF) study is to validate the approved US TOBI Podhaler Instructions for Use (IFU), by establishing that the IFU effectively communicates the information necessary to achieve safe and effective use of the Podhaler device.

The morbidity and mortality associated with Cystic Fibrosis (CF) are the result of chronic suppurative lung disease. The aggressive use of antibiotics is one of the mainstays of treatment in CF, however, the problems of multiple drug resistance and adverse reactions are major clinical issues. Cysteamine is a licensed drug used in the treatment of cystinosis. In vitro work suggests that cysteamine has properties of potential benefit in CF. Cysteamine is a potent mucolytic, it disrupts biofilms, it is antimicrobial, and synergises with other antibiotic agents. CF is characterised by malabsorption and it is not known whether cysteamine is absorbed in CF, furthermore it is not known if cysteamine enters the bronchial secretions. It is not possible to assume that the pharmacokinetics of cysteamine in patients with CF are the same as those reported for cystinosis. Objectives: to characterise the pharmacokinetic profile of cysteamine in people with CF, to ascertain whether cysteamine enters the bronchial secretions and the tolerability of cysteamine by patients with CF. Method: a single centre, single group open label investigation of the tolerability and pharmacokinetics of oral cysteamine (Cystagon) when administered to patients with Cystic Fibrosis at the dose licensed for use in cystinosis. Setting: adult CF clinic, Aberdeen Royal Infirmary. Target population: 12 patients aged ≥18years with CF associated lung disease who are clinically stable. Intervention: Oral cysteamine (Cystagon) will be increased from 450mg od to 450mg qds over three weeks, they will remain on 450mg qds for two weeks. Assessment: face to face health outcome assessments will be carried out for all participants at recruitment/baseline, 1, 2, 3, and 5 and 6 weeks. Serial blood cysteamine levels will be measured in the first 24 hours after the first dose. Sputum cysteamine will be quantified after two weeks of full dose cysteamine 450mg qds. Disease specific health status (CFQ-R) will be assessed at baseline and after two weeks of full dose. At each assessment, lung function (FEV1, FVC), adverse reactions and serious adverse events will be ascertained. Blood samples will be taken for measurement of haematological and biochemical parameters. Sputum samples at each assessment will be analysed for microbial load and spinnbarkeit.
