Active clinical trials for "Cystic Fibrosis"

The pandemic forced us to develop home follow-up for patients with chronical diseases . In the same time, the new era of treatment for cystic fibrosis considerably improves the health of patients with this pathology. This study aims to assess the satisfaction of patients and care providers for an alternated follow-up between tele-consults and in-hospital consults during one year for patients with cystic fibrosis treated by Kaftrio® since at least one year and stable.

There is established evidence that adult patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Cefiderocol is a newly approved broad spectrum intravenous siderophore cephalosporin antibiotic, which has potent in vitro activity against multidrug resistant Pseudomonas aeruginosa, Burkholderia cepacia complex, Achromobacter species, and Stenotrophomonas maltophilia, all pathogens implicated in CF pulmonary exacerbations. This study will determine the pharmacokinetics and tolerability of cefiderocol in 12 adult CF patients admitted for a pulmonary exacerbation at one of 4 participating hospitals in the US. Patients will remain on standard of care IV antibiotics and receive 4-6 doses of cefiderocol 2 grams infused over 3 hours every 6-8 hours, depending on kidney function. Blood will be sampled after the final dose to determine concentrations and pharmacokinetics of cefiderocol. Safety and tolerability will be assessed throughout the 2 day study.

Cystic fibrosis (CF) is an autosomal recessive disease caused by alterations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, characterized by multisystemic alterations, mainly in the lung, intestine, sweat, and bile ducts. In addition to pulmonary involvement, the presence of exocrine pancreatic insufficiency also increases the risk of survival, as it is associated with malnutrition and deficiency of fat-soluble vitamins, such as vitamin D. Vitamin D, in addition to its role in bone health, in the case of CF patients with chronic inflammation, it has been suggested that many of the cytokines that regulate the inflammatory response contain elements that respond to vitamin D, so vitamin D could play an essential role in the regulation of the inflammatory response in CF, which could favor lung function. However, more than 50% of CF patients present vitamin D insufficiency or deficiency, despite the different schemes suggested for supplementation in different age groups, which suggests that new strategies are needed to normalize vitamin D levels, which will allow us to see its clinical effect on the inflammatory response, by decreasing the number of exacerbations and thus perpetuating or improving lung function, as well as on bone mineral health.

Background Cystic fibrosis is a life-threatening genetic disorder responsible for pulmonary failure and multi-systemic complications involving specific and large medical care burden. To date, no program has shown its effectiveness in improving therapeutic adherence. A new approach to develop a co-constructed program involving patients and professionals may contribute to improve therapeutic adherence. Objectives The aim of the MUCOBS-Trial project is to create a program to increase therapeutic adherence and to evaluate its efficacy in adult patients with cystic fibrosis in 3 CF centers in France.

This is an open-label, single center, prospective study of patients with a diagnosis of cystic fibrosis (CF) and a history of methicillin-resistant Staphylococcus aureus (MRSA), also known as oxacillin-resistant Staphylococcus aureus (ORSA), being treated with intravenous ceftaroline. Patients will have intravenous ceftaroline dosed according to current recommendations based upon its approved usage in pediatric patients for community acquired pneumonia. The investigators will analyze pharmacokinetic (PK) and pharmacodynamic (PD) data using serum concentrations of ceftaroline measured at various time-points following infusion of ceftaroline to develop PK/PD guided dosing strategies of ceftaroline in pediatric CF patients that would be tailored to account for bacterial susceptibility and disease progression.

This is a Phase 2 study with primary objective of looking whether YPT-01 phage therapy reduces sputum bacterial load in cystic fibrosis subjects with Pseudomonas aeruginosa. In addition, study evaluates the safety profile of phage therapy in this patient population.

The aim of this study is to assess the utility of CGMs to determine the optimal method to dose meal-time insulin. The investigators will examine glucose excursions in patients with CF who will dose meal-time rapid-acting insulin by carbohydrate counting versus fixed-dose rapid-acting insulin. The carbohydrate ratio and fixed doses will be determined by existing doses, total daily insulin doses, body weight, and insulin sensitivity along with predisposition to hypoglycemia. Bolus insulin dosing is an important part of CFRD management due to the high nutritional demands of these patients. If dosed incorrectly, this could lead to marked hyperglycemia and could worsen nutritional status due to urinary glucose losses. In this project, the investigators will perform a within-subjects' comparison of the 2 standard methods of meal-time rapid-acting insulin dosing.

Cystic Fibrosis Related Diabetes has been identified by the CF community as one of the top ten priorities for CF research. In CF clinical decline due to dysglycemia begins early, prior to diagnosis of diabetes and increases mortality from pulmonary disease. There is presently no way to determine who, of those with dysglycemia, will experience clinical compromise. However, the CF Center in Milan has found that measurable age- and sex-dependent variables on oral glucose tolerance testing (OGTT) predict β-cell failure-the primary driver of decline in CF. the investigators propose a multi-center trial to develop nomograms of age and sex dependent reference values for OGTT-derived measures including glucose, insulin, c-peptide, and the resultant OGTT-derived estimates of β-cell function, β cell sensitivity to glucose, and oral glucose insulin sensitivity (OGIS) and to determine correlation of these with clinical status (FEV-1, BMI z score, number of pulmonary exacerbations over the past 12 months). In a subset of the cohort the investigators will perform additional studies to determine possible mechanisms driving abnormal β cell function, including the role of lean body mass (as measured by DXA), impact of incretin (GLP-1, GIP) and islet hormones (glucagon, pancreatic polypeptide) on β cell function and the relationship of reactive hypoglycemia and catecholamine responses to β cell function, as well as the relationship of β cell sensitivity to glucose as determined by our model to abnormalities in blood glucose found in a period of free living after the study (determined by continuous glucose monitoring measures (Peak glucose, time spent >200 mg/dl, standard deviation). the investigators will also develop a biobank of stored samples to allow expansion to the full cohort if warranted and to enable future studies of dysglycemia and diabetes in CF. the investigator's eventual goal is utilization of the nomograms to determine the minimum number of measures to accurately predict risk for clinical decline from dysglycemia in CF.

Cystic fibrosis (CF) is the UK s most common inherited genetic condition and affects more than 10,500 people. The disease causes problems with the movement of salt and water in the body, resulting in sticky mucus building up, mostly in the lungs and gut. Thick mucus in the airways leads to repeated infections which, over time, damage the lungs. Chest physiotherapy is prescribed to loosen and clear sticky thick mucus from the airways and so to help to reduce lung infection. Chest physiotherapy is a routine treatment to keep people with CF healthy. However, many say it is time-consuming and a burden. People with CF have asked if doing exercise could have the same effect as chest physiotherapy sessions for helping clear mucus. Exercise could be more enjoyable and less burdensome. Through a recognised priority setting partnership, the CF community recently ranked research to reduce the burden of their care and answer whether exercise can replace chest physiotherapy , as their number 1 and 7 priorities. Surveys show that many people with CF have occasionally chosen to replace chest physiotherapy with exercise for airway clearance, and we recently confirmed this through a UK-wide survey. It is not known if they would be willing to take part in research that asks some to stop chest physiotherapy and to exercise (with coughs and huffs) instead. New medicine (modulators) have recently become available for many people with CF, bringing dramatic improvements in their health. Some people who have started modulators are considering whether they can reduce or stop treatments - including chest physiotherapy. So, the effects of stopping chest physiotherapy need to be investigated and also if exercise can be used instead - this research study aims to understand this. A recent survey in people with CF, their families, physiotherapists and doctors, conducted by this research team, showed us that many consider hard exercise with coughs and huffs to be able to clear mucus from the airways. This study will recruit 50 people with CF (>12 years old) for 28-days. This study will ask half of them to continue their usual care, and half to stop chest physiotherapy and do exercise that gets them breathing deeply (with coughs and huffs) instead. This study will see if people are willing to start and continue with such a study and what they think of the study processes. It will also see how stopping chest physiotherapy and replacing it with exercise affects measurements of their lung function. The study will also involve talking with people with CF and members of their CF team to understand their experiences. This information will reveal whether a larger study can answer the question of whether certain forms of exercise can safely be used as an alternative to chest physiotherapy.
