Active clinical trials for "Cystic Fibrosis"

The main objective of the study is to evaluate the short-term effects of the airway clearance technique by the medical device Simeox (Physio Assist, France) versus Autogenic Drainage, on the pulmonary function of adult patients with stable cystic fibrosis. To analyse these effects, the investigators used forced oscillation technique measured by TremoFlo™ C-100 Airwave Oscillometry System™ (THORASYS Thoracic Medical Systems Inc. Montreal, Quebec, Canada) with an evaluation of the perceived clinical benefits.

This clinical study will enroll 42 participants without the F508del mutation, carrying partial function or N1303K mutations not approved for Trikafta, and who are not expected to be approved for CFTR modulator treatment in the immediate future. Each participant will be given Trikafta for approximately four weeks. The study researchers will monitor clinical endpoints that include forced expiratory volume (FEV1) and sweat chloride. Additionally, the researchers will obtain skin biopsy material and/or blood sample from each subject so that induced pluripotent stem (iPS) cells can be modified into airway cell monolayers and tested for response to Trikafta. In this way, the study will evaluate an emerging and readily accessible in vitro endpoint as a predictor of clinical response. This study will serve as a pilot/test case for other clinical protocols relevant to patients with rare CFTR variants who do not currently receive modulator therapies. It is hypothesized that a robust correlation will be established between in vitro Trikafta responsiveness of iPS cells and in vivo benefit (FEV1) to patients, and will provide a new tool for utilizing iPS to identify patient populations most suitable for cystic fibrosis modulator therapy.

OBJECTIVES Primary: To evaluate efficacy of treatment with anakinra in subjects with CF who are ≥ 12 years of age by means of lung clearance index (LCI). Secondary To evaluate safety and tolerability of treatment with anakinra as well as to investigate further effects of anakinra on lung function and quality of life (QOL) in subjects with CF.

To evaluate the micro-biologic efficacy and safety of a streamlined treatment for early onset methicillin-resistant staphylococcus aureus (MRSA) in patients with cystic fibrosis.

The purpose of this study is to assess the safety and tolerability of two 5-day infusion cycles of IV gallium in adult patients with CF who are infected with NTM. Funding Source - FDA OOPD

Determine the safety, tolerability and pharmacokinetics of single doses of ARCT-032 in healthy adult subjects.

Cystic fibrosis (CF) is the most common severe autosomal recessive genetic disease in Caucasians. The CFTR (cystic fibrosis transmembrane regulator) gene, which encodes the chloride channel of the epithelial cell membrane, is responsible for the development of the disease. Respiratory physiotherapy, especially bronchial drainage is one of the basic elements of comprehensive management in patients with CF. Among the many procedures used in CF drainage physiotherapy, the most commonly include these using positive expiratory pressure (PEP) and oscillating positive expiratory pressure (OPEP). The aim of the study is to assess the efficacy of the usage of selected PEP and OPEP devices in bronchial drainage in cystic fibrosis patients during exacerbation of the disease.

Cystic Fibrosis (CF) is an autosomal recessive disease cause by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) manifesting in multiple organs, the most common cause of morbidity and mortality continues to be the pulmonary manifestation. CFTR dysfunction leads to reduced mucociliary clearance, impaired innate immune system function in the lungs (within the airway surface liquid [ASL] lining the epithelial barrier of the lungs) and reduced ASL hydration (stickier mucus). To try and help correct this underlying defect patients have been performing airway clearance for decades using different techniques (Percussion and postural drainage [P&PD], Positive expiratory pressure [PEP], Oscillatory positive expiratory pressure [OPEP], High-frequency chest compression [HFCC], exercise), inhaled mucolytics (Hypertonic Saline, Pulmozyme) and inhaled antibiotics. However, performing daily airway clearance can be a large burden on patients and their families with a median number of daily therapies around 7 and average time spent on therapies at almost 2 hours daily. This high treatment burden leads many patients to have reduced adherence to their regimens and multiple studies have shown around 20% of patients performing no daily airway clearance. Since the release of highly effective CFTR modulator therapy patients have experienced improvements in lung function measurements and imaging-based ventilation measurements, reduction in pulmonary exacerbations, and improvement in daily symptom scores. Over 80% of patients and their families and over 95% of clinicians in the United States support the idea of trials looking into the simplification of airway clearance regimens. Combining the inability of most patients to complete their daily regimens, patient and clinician interest in treatment simplification research, and the overwhelming cost of most inhaled medications in cystic fibrosis with the improvement in mucociliary transport and symptoms with highly effective modulator therapy suggests a research program aimed at reducing the treatment burden of daily airway clearance should be considered. The investigators propose the following: determine if there is additional benefit in continuous airway clearance regimens after starting Elexacaftor-Tezacaftor-Ivacaftor (ETI) and if so, is this benefit noticeable on pulmonary function testing and imaging.

This will be a 5 year randomized, double blind, placebo controlled trial of 7 days of oral prednisone in cystic fibrosis (CF) patients receiving intravenous (IV) antibiotic treatment for a pulmonary exacerbation at the Hospital for Sick Children and other study sub-sites across Canada. The intervention will be oral prednisone 2 mg/kg/day (max 60 mg) divided twice daily for 7 days as an adjunctive therapy for pulmonary exacerbations in CF patients who have not recovered their baseline forced expiratory volume in 1 second (FEV1) after 7 days of IV antibiotic treatment. The primary outcome will be the proportion of subjects who achieve >90% of their baseline FEV1 % predicted at day 14 of IV antibiotic treatment for a pulmonary exacerbation in each treatment arm.

The purpose of this study is to explore the use of off-label CFTR modulators that may affect CFTR function in patients with CFTR mutations that are not currently approved for these drugs.
