Active clinical trials for "Cystic Fibrosis"

Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.

This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres throughout the United Kingdom. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care.

Lung disease is the predominant cause of morbidity and mortality in Cystic Fibrosis (CF) with 80% of deaths resulting directly or indirectly from pulmonary disease. Abnormal airway clearance causes retention of mucus resulting in frequent chest infections. Physiotherapists use different techniques to help clear mucus from the lungs of patients with CF. Inhaled medications and airways clearance techniques (ACTs) are central to a CF patient's daily treatment and are often coordinated. Burden of treatment is a common reason for non-adherence in this patient group, and streamlining of treatment timings is sought to optimize adherence whilst ensuring efficacy to an often complex daily regimen of inhaled bronchodilators, nebulizers and ACTs. A gap in the research exists as to the optimal timing of Hypertonic Saline (HTS) and ACT within the daily regimen. A study to show whether the timing of HTS around ACT is significant, can better inform patients and potentially allow more flexibility around their treatment regimen. Lung Clearance Index (LCI) has shown good sensitivity to abnormalities in lung function compared with spirometry and has demonstrated a treatment effect in other trials. LCI may be a suitable tool therefore, to assess intervention strategies aimed at airways clearance in CF. This study aims to compare the effects ACTs after HTS inhalation versus ACTs during HTS inhalation as measured by LCI. It is a randomized, crossover trial of ACTs after HTS inhalation compared with ACTs during HTS inhalation in adult CF patients during day 10-14 of a hospital admission for treatment of a pulmonary exacerbation. Patients will be randomized to receive 1 of the treatment session options on the first day and the reverse on the second day. The primary objective of this study is to compare the change in LCI (a measure of lung function) at 90 minutes post treatment with ACTs after HTS inhalation compared with ACTs during HTS inhalation in adult CF patients.

This study is designed to assess the safety, tolerability, pharmacokinetics and preliminary pharmacodynamics (proof of concept) of QBW251 in healthy subjects and cystic fibrosis patients following single and multiple doses. This first-in-human and proof of concept study will consist of 4 parts, with Parts 1 and 2 in healthy volunteers and Parts 3 and 4 in cystic fibrosis patients.

The purpose of this trial is to evaluate the effects of a single dose of denufosol versus placebo on mucociliary clearance in patients with mild to moderate CF lung disease

This study examines "modifier genes" that may play a role in the development of CF liver disease. Modifier genes are genes, other than the CF gene (CFTR), which may directly or indirectly have an affect on how the body responds to the conditions that develop as the result of the defective CFTR gene. Scientists have wondered why some patients with CF develop CF liver disease and why some patients with CF do not. To better understand the problem, this study was designed to examine the genetic makeup of CF patients who are considered to have severe liver disease to see if they can identify any modifier genes. Researchers will study blood samples, pulmonary function tests, and other medical information in hopes that a connection can be made between genetic make-up and how severe the liver disease is. The identification of modifier genes that influence disease severity may ultimately lead to a better understanding of CF liver disease, and may be useful in the development of new treatments.

Our hypothesis is that Growth Hormone (GH) will not only target the peripheral tissue to stimulate weight and muscle growth which will maximize nutritional potential and improve overall quality of life. We theorize that this will occur through a multitude of factors: increased appetite, more constructive utilization of caloric intake and decreased catabolic signaling. The first aim will address changes in weight and lean body mass following the institution of GH therapy in adults with Cystic Fibrosis (CF) related wasting. The second aim will measure impact on quality of life of these individuals. Additionally, the third aim will monitor effects of GH therapy on diabetes and insulin sensitivity. Finally, the fourth aim will observe changes in the subjects underlying diagnosis of CF, specifically lung function, muscle strength and inflammatory state.

The purpose of this study is to compare the effect of three airway secretion clearance techniques (chest physical therapy, flutter device and high frequency chest wall oscillation) on decline in pulmonary function over a three year period in patients with cystic fibrosis.

The purpose of this study is to obtain data on the potential of long-term treatment with denufosol to improve the clinical course of CF lung disease in patients with mildly impaired lung function and to provide CF patients who completed study 08-110 continued access to denufosol.

The aim of this trial was to compare the safety and efficacy of courses of tobramycin and ceftazidime, administered intravenously as either thrice daily short infusions or 24 h continuous infusion, in cystic fibrosis patients with acute exacerbation of chronic pulmonary PA infection. In conventional treatment regimens, ceftazidime is administered in the form of thrice daily short infusions, but pharmacodynamic considerations suggest that continuous infusion could be more effective.
