Filter by:CF is caused by mutations in the gene that encodes the 'Cystic Fibrosis Transmembrane Conductance Regulator (CFTR)' channel. To re-establish the function of this complex chloride channel, typically two to three drug modes of action are needed. To date, clinical studies of CFTR modulators have focused on patients carrying the F508del CFTR mutation, which is present in approximately 80% of CF patients, or gating mutations which are present in 5% of CF patients (gating mutations result in a reduced opening of the CFTR-channel at the cell surface which limits the flow of chloride ions through the CFTR channel). Although CF is a monogenetic disease, the 15% remaining patients represent more than 2000 different rare and mostly uncharacterized CFTR mutations. Multiple pharma companies have one or more CF drugs in their developmental pipeline. However, it is not known which patients may respond to the drugs in the pipeline. It is hypothesized that by using individual patient's intestinal organoids to screen for drug response, a subset of patients with rare CFTR mutations can be identified who will clinically respond to drugs in the developmental pipeline. The Human Individualized Therapy of CF (HIT-CF) project has been designed to further evaluate this hypothesis. The project has received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No 755021. The core of the project consists of a two-step approach to identify patients outside the existing drug label who may also benefit from CFTR-modulator treatment. In the first step of the project (HIT-CF Organoid Study, NTR7520), novel CFTR modulators and their combinations were tested on organoids from over 500 European and Israeli CF patients with rare CFTR mutations to identify patients who are predicted to clinically benefit from these treatments. The second step will evaluate the predicted clinical effect of the CFTR modulators in subjects identified by their organoid response to investigational products. CFTR modulators from the HIT-CF participating pharmaceutical company, FAIR Therapeutics, will be evaluated in the CHOICES clinical study described in this protocol. Data from this clinical study will be compared with the HIT-CF Organoid Study results to validate the organoid model.
The goal of this clinical trial is to learn if drug SPL84 is safe for adult patients with cystic fibrosis (CF). It will also learn if the drug works to treat works to treat CF with a specific mutation. The purpose of this research study is to: - test the safety and effectiveness of multiple doses of the study drug, SPL84 - test how multiple doses of the drug are processed by the body Researchers will compare drug SPL84 to a placebo (a look-alike substance that contains no drug) to see if drug SPL84 is safe and if it works to treat CF. Participants will: Take drug SPL84 or a placebo by inhalation every week for 9 weeks months Visit the clinic approximately 14 times over 17.5 weeks for checkups and tests
In this project the investigators aim to identify new biological markers by characterizing the response/inflammation associated with the development and progression of M. abscessus lung disease in patients suffering from cystic fibrosis with the aim of increasing current knowledge available on the development and progression of lung disease.
The pathogenicity of Achromobacter bacteria is not yet well established, but studies show a decline in respiratory function and an increase in mortality associated with chronic colonisation, making it possible to classify the Achromobacter genus as an emerging pathogen in cystic fibrosis. It is possible that certain species or clones are more virulent or resistant, requiring the adaptation of measures to prevent cross-transmission in the centres concerned. However, until now, the identification of Achromobacter species has involved the use of molecular biology techniques that are not routinely applicable in diagnostic laboratories, limiting studies and the collection of epidemiological data. Recently, a database using MALDI-TOF mass spectrometry has been built for rapid and accurate species identification. In view of the local epidemiology and the current lack of data, it would be necessary and interesting to use this tool to study a cohort of cystic fibrosis patients in Réunion island (North and South sites) to see whether one species has a greater clinical impact than another (pathogenicity), and/or is more responsible for chronic colonisation.
Cystic fibrosis (CF) is a rare disease affecting one out of 4,500 newborns in France (INSERM 2021). Despite major advances in patient care over the past two decades, with significant improvements in life expectancy, cystic fibrosis remains a pathology that considerably impairs quality of life. Several studies have reported the possibility of respiratory and non-respiratory sleep disorders (SD) in patients with CF. Respiratory disorders are reported to affect 30% of children with CF (Barbosa 2020). Among non-respiratory SD, sleep onset and maintenance insomnia are well known in these patients, while chronotype abnormalities (circadian rhythm disorders) are understudied. Chronotype refers to a person's tendency to be more efficient in the morning or evening. The existence of chronotype abnormalities has been suggested in CF patients, but no precise data are available (Louis 2022). The involvement of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) protein dysfunction in the central nervous system (CNS) has been hypothesized as a contributory factor. In vivo, in a mouse model of CF, dysregulation of clock genes such as Clock, Cry2 and Per2 was found in the CNS (Barbato 2019). Among them, certain genes such as Rev-erbĪ± could regulate endobronchial inflammation and contribute to the severity of respiratory pathology. All in all, chronotype abnormalities could be at the origin of sleep debt, impaired cognitive functions or metabolic disturbances. In the era of highly effective modulator therapy (HEMT) for the treatment of CF, the impact of these new therapies on chronotype has been understudied. Assuming that chronotype abnormalities are a direct consequence of CFTR protein dysfunction in the retina and anterior hypothalamus, HEMT should improve sleep quality. However, between 20% and 30% of adult and pediatric patients express an increase in chronotype abnormalities following initiation of treatment. Paradoxically, the perceived gain in respiratory quality of life is counterbalanced by the occurrence of these disorders. Some patients would effectively reverse their treatment in order to limit the phenomenon. A single polysomnographic study evaluated the effect of HEMT Kaftrio-Kalydeco on sleep in adults with CF (Welsner 2022). After 3 months of treatment, patients had a significant reduction in respiratory events, with no change in total sleep time, sleep efficiency or sleep architecture. Chronotype was not mentioned. Currently, no studies on chronotype in children or adults with CF have been carried out. Our hypothesis is that CF patients treated with HEMT would develop an abnormal chronotype of late sleep onset. The aim of this study is to evaluate the chronotype of children with CF treated with HEMT. Chronotype abnormalities could have major consequences for quality of life, the immune system, cognitive functions and metabolism. Systematic detection of these disorders via anamnesis, followed by diagnosis by questionnaire, actimetrics and/or urinary melatonin dosage, would enable their early management, starting with the reversal of Kaftrio-Kalydeco intake between morning and evening.
The goal of this clinical trial is to test use of losartan in those with cystic fibrosis (CF) on modulator therapy. The main question it aims to answer is if treatment with losartan improves response of the CF transmembrane conductance regulator (CFTR) channel to modulator therapy. Participants will be asked take losartan or placebo for twelve weeks and will have changes in sweat chloride levels measured as a marker of CFTR function.
The goal of this study is to determine the extent to which excess dietary simple sugars serve as a secondary mediating factor in Cystic fibrosis-related diabetes (CFRD) development. The main questions it aims to answer are: - Whether conducting a randomized 2x2 factorial design that evaluates acute postprandial changes in glucose over 2 hours following ingestion of a mixed meal challenge that varies by glycemic index and consumption of a sugar-sweetened beverage is acceptable and feasible. - What are the preliminary changes in postprandial hyperglycemia, islet cell function, and incretin response to a high or low Glycemic Index mixed meal tolerance test (MMTT) with and without Sugar-Sweetened Beverages (SSB) in adolescents and young adults with CF Participants will be randomized to a mixed diet and blood will be drawn before and after the mixed meal challenge.
The main reason for this research study is to learn more about some new tests that are being developing for patients with Cystic Fibrosis (CF) to measure changes in the lungs. In this study, the focus will be to learn how stopping Airway Clearance (ACT) and re-starting ACT can affect these tests. These new tests include using a breathable gas called Xenon (Xe) with MRI (magnetic resonance imaging) to improve the pictures of changes in the lungs. The Xenon (Xe) gas that has been treated to have a larger MRI signal (also called hyperpolarized). The other new test is called LCI (Lung Clearance Index) that can measure how well the lungs are working. The MRI machine used in this study has been approved by the U.S. Food and Drug Administration (FDA) and is commercially available for sale in the USA. Hyperpolarized Xe gas is an FDA-approved, inhaled contrast agent for lung ventilation MRI. The new Xe MRI techniques that are being developed and used for this research study are investigational, meaning these new Xe MRI techniques are not FDA approved, but they are similar to FDA-approved techniques that are used clinically at Cincinnati Children's Hospital Medical Center (CCHMC). Xe gas and the new MRI techniques used in this research study have been used for many years in research, including in many research studies conducted at CCHMC like this one.
The main objective of the study is to determine the impact of cystic fibrosis affecting a child on the parents' quality of life, their possible anxiety and depressive symptoms, their general fatigue and the feeling of burden in these caregivers.
Recently, the treatment of Cystic Fibrosis (CF) incorporated new modulators/enhancers of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). It is thus increasingly important to study the side effects of these drugs, their extrapulmonary effects and possible interaction with other drugs and with exercise. For this purpose, a randomized controlled trial is proposed to determine the effects of a telematic exercise intervention on muscle health, in a group of 48 children and adolescents with CF treated with these new generation CFTR modulators. They will be randomly assigned to two groups (exercise and control group). The effect of the intervention will be analysed measuring the variables of muscle health, cardiorespiratory fitness, lung function, body composition, inflammatory biomarkers and miRNAs. After completion of the intervention program, adherence to exercise and clinical evolution after one year will be analysed.
