Active clinical trials for "Cystic Fibrosis"

The purpose of this research study is to test a new combination of medicines, Phenylbutyrate and Genistein, to determine if they could be used to treat cystic fibrosis (CF). The most common genetic mutation found in patients with CF is called Delta F508. Due to this mutation, there is a lack of salt (chloride) movement in your nose, sinuses, lungs, intestines, pancreas and sweat glands. This lack of movement causes the clinical manifestations of the disease. Although Phenylbutyrate has been extensively used to treat patients with rare metabolic diseases, 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. When used together, both drugs may be able to restore normal chloride and salt (water) movements in body organs and glands in people with CF. We will be studying salt and water movement in the nose by a technique called nasal transepithelial potential difference (NPD).

The purpose of this research study is to learn about the activity of oral Pancrecarb® (a pancreatic enzyme preparation which contains proteins that help to digest food), administered by mouth as a capsule filled with specially coated granules in patients taking exogenous pancreatic enzyme therapy. Specific enzymes activities will be determined from samples of stomach and intestinal fluids after a standard liquid meal.

The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.

This is a project that will determine whether the use of daily bright light therapy has an effect on depressive symptoms experienced by adult inpatients with CF and COPD. The purpose of this project is to apply a daily 30-minute BLT intervention to hospitalized adult CF and COPD patients in order to decrease symptoms of depression as measured by depression inventory scoring.

Meropenem is an intravenous antibiotic commonly used to treat acute exacerbation of respiratory infections in cystic fibrosis. The research study aims to determine if a different method of infusing the drug over 3 hours or longer, instead of the traditional half-hour will improve target attainment of drug concentrations and bactericidal activity. A secondary aim is to assess if the pharmacokinetics of meropenem is different during active infection compared to non-infective stage. Twelve patients admitted with acute respiratory infection and who requires meropenem will be enrolled into the study. Meropenem blood concentrations collected over 8 hours will be measured after half-hour and 3-hour infusions on different days. A pharmacokinetic modelling and Monte Carlo simulation program will use the data to assess and predict the optimal method of dosing. When patients return for a follow-up clinic visit, a single dose of meropenem will be administered and blood concentrations will be measured to determine the pharmacokinetics during non-infective stage.

This is an add-on, randomized, open label, clinical trial that evaluates the use of quadriceps electrostimulation as an additional retraining procedure in patients suffering from cystic fibrosis.

The purpose of this study is to identify new methods of measuring and improving collaborative goal setting between patients and clinicians in adult cystic fibrosis care.

This study will evaluate the efficacy and safety of an oral ARV-1801(ACG-701) plus optimized background therapy (OBT) compared to oral placebo plus OBT, each administered for 14 days, in the treatment of participants with Cystic Fibrosis-related pulmonary exacerbations (PEx).

Cystic Fibrosis is a hereditary, chronic respiratory illness. Cystic Fibrosis leads to a progressive decline in lung function. School-aged children with cystic fibrosis experience backpack carrying everyday. Backpack carrying induce a restrictive effect responsible for lower lung function. Respiratory muscle strength is also impaired. No studies assessed aerobic capacities during children's gait while carrying a backpack. The investigators hypothesized that backpack carrying will induce an acute decline in lung function in children with cystic fibrosis compared to healthy children. Investigators also hypothesized that aerobic capacities will be impaired.

Cystic fibrosis (CF)-related diabetes (CFRD) is the most common complication after pulmonary complications. This specific form of diabetes is associated with an increased morbidity and mortality. CFRD prevalence at the age of 10 is 10% and reaches 40 to 50% in adulthood, while another 35% of adult patients presents impaired glucose tolerance. In order to identify patients at risk and to implement early therapeutic measures, an annual CFRD screening test should therefore be undertaken for CF patients after 10 years of age. The 2-hour oral glucose tolerance test (OGTT) with a sweet beverage is the recommended screening test. However, participation rates for screening tests are far from optimal. For examples, in 2015, the investigators observed that only 47% of non-diabetic patients attended to planned screening despite large availability and advertisement (unpublished data). Comparable low levels of screening for CFRD, usually below 33%, have been reported by various teams. Several reasons could explain these low adherence rates. Some factors are related to patients perceptions and experience: OGTT is perceived as an additional medical burden requiring a scheduled appointment (several weeks after the last exacerbation); overnight fasting followed by the intake of a large glucose load within 5 minutes can lead to nausea, headache, bloating and fatigue; some patients fear multiple blood sampling, etc. In addition, in case of CFRD diagnosis, recommended capillary blood glucose monitoring, nutritional advice and treatment (insulin) are perceived as extremely invasive and complex, thus some patients prefer avoiding screening test. To date, no alternative screening method has demonstrated its effectiveness to screen for CFRD. The investigators of this study believe that a simplified version of the OGTT would be more attractive, would make it more acceptable for patients and has the potential to improve their adherence to screening tests, simplify CF-team works and reduce costs. By allowing appropriate education and introduction of treatment in a timely manner, improved adherence to annual screening for dysglycemia has the potential to minimize or prevent clinical deterioration observed in years preceding CFRD onset.
