Active clinical trials for "Cystic Fibrosis"

Cystic fibrosis (CF) is an illness that makes the lungs clog up with sticky mucus. There is no cure and so treatments are used to help make the illness easier to live with. The treatment can take lots of time and can feel not very nice sometimes. When children with CF become teenagers they need to learn to take charge of their treatment. This can be difficult. Teenagers with CF want to fit in with friends and can become more upset about their illness. Their parents have to learn to let their child take charge of their illness which can be hard for parents. These issues can put strain on parent-child relationships and this can make it harder for teenagers to stick to their treatment plans. A parenting program (called Teen Triple P) has been shown to help teenagers with other illnesses (such as diabetes) to be able to stick to their treatment plans. Parents are given a booklet to work through at home which helps them to build on the skills they already have. It aims to help families to support positive parent-child relationships, to manage difficult teenage behaviours, and to teach new skills and behaviours. So far no one has done any research to see if this program helps families of teenagers with CF. This research would like to see if the Triple P program can help teenagers with CF stick to their treatment plan. Helping teenagers stick to their treatment plan will help them to live happier and healthier lives.

It is the goal of the proposed study to compare the efficacy, as assessed primarily by sputum weight, of these two different devices (the Electroflo 500 and the G5 Flimm-Fighter) for airway clearance (AC) in CF patients with mild to moderate lung disease, who have stable lung health and perform AC at home as part of their routine therapeutic regimen.

The purpose of this research study is to characterize the pharmacokinetics of intravenous ceftazidime/avibactam in patients with Cystic Fibrosis.

Individuals living with cystic fibrosis (CF) commonly report high symptom burden, poor quality of life, and additional psychosocial stressors; these burdens are particularly heightened in advanced stages of the disease. Although supportive care (aka palliative care) has been shown to improve many of these outcomes among patients with illnesses such as cancer, no clinical trials to date have tested the impact of supportive care for patients with CF. The purpose of this pilot randomized clinical trial study is to evaluate the feasibility, acceptability, and perceived effectiveness of an embedded supportive care intervention, whereby a supportive care specialist will be integrated within the usual care experience of patients with advanced CF. The investigators will enroll 50 patients with advanced CF, who will be equally randomized to receive this embedded supportive care intervention or usual care. Secondary measures include: patient quality of life, mood, coping style, satisfaction with care, and symptom burden. This study will provide preliminary data to support the development of a larger, definitive, Phase III randomized clinical trial.

This is a Phase 1, first-in-human (FIH) single ascending dose study being conducted to better understand the safety, tolerability and pharmacokinetics of AZD5634 in healthy subjects

To determine the pharmacokinetics of single and multiple doses of FDL169 in healthy female subjects.

The strategy of neonatal screening for Cystic Fibrosis in France relies on Immuno Reactive Trypsinogen (IRT) at day 3/DNA analysis with a CF Elucigen 30 mutations kit/ IRT safety-net at day 21. This strategy has significantly improved the performance of CF neonatal screening (NNS) in terms of positive predictive value and sensitivity but revealed new difficulties. Up to 85-90% of CF patients detected through the NNS program has a classical CF form with a positive sweat test and 2, 1 or no CF causing mutations but the remainder has either 2 CFTR mutations with at least one non-CF causing mutation and a sweat test <60mmol/L or 1, 0 CFTR mutation and an intermediate sweat test value ≥ 30 et < 60mmol/L raising a diagnosis and prognosis dilemma. Meanwhile the vast majority of these cohorts will remain asymptomatic over time, some will develop symptoms prompting clinicians to maintain a rigorous surveillance for the entire atypical cohort, whose modalities vary a lot among centers and countries. This prospective multicenter study with a standardized assessment of a matched cohort with "atypical" CF versus "classical" CF from 6 years of age (60-65 cases in each cohort) is aimed at evaluating pulmonary and nutritional status to, better define the best monitoring follow-up, therapeutic management and familial genetic counseling.

Direct measurement of mucociliary and cough clearance (MCC/CC) has been used as a biomarker in cystic fibrosis (CF). Additional knowledge of the performance of this biomarker is needed to inform exploratory clinical trial design in support of programs to develop new inhaled therapies for CF. We hypothesize that MCC/CC measurements can be used to determine the durability of action of agents like hypertonic saline (HS) which increase epithelial lining fluid height.

To determine the pharmacokinetic profile of IV (intravenous) and PO (oral) formulations of linezolid among children with cystic fibrosis and establish a dose regimen that will be safe and effective.

Serine proteases belonging to the elastase family are mainly responsible for lung tissue destruction as observed during cystic fibrosis. But anti-inflammatory therapies based on systemic or aerosolized protease-inhibitors administration, have not given the expected results until now. One reason would be the impaired access of therapeutic inhibitors to their molecular targets. It was recently shown that neutrophils actively secrete neutrophil extracellular traps (NETs) made of DNA that binds cationic proteases among other molecules. NETs together with DNA passively released from dead neutrophils contribute to the viscosity of CF expectorations which explains that rhDNase treatment fluidifies expectorations and improves the patient status. Preliminary experiments in our laboratory have shown that DNA degradation was associated with a significant increase of proteolytic activity in the sputum soluble fraction. However the efficacy of exogenous inhibitors is also improved in these conditions. Using the specific substrates and methodologies that we developed previously to measure cell-surface associated proteolytic activities, we will study the effects of DNase on the activity of individual proteases, their biodistribution in sputum and their regulation by potential therapeutic inhibitors. Enzymatic, immunochemical and microscopic (confocal and scanning) techniques will first be used for ex vivo studies on sputa freshly collected at the adult and paediatric CRCM in Tours, then on sputa from patients before and after administration of aerosolized rhDNase. We hypothesize that a better understanding of the biodistribution of neutrophil serine proteases and especially their binding to DNA will help designing new therapeutic strategies that facilitate inhibitor access to their protease targets.
