Active clinical trials for "Cystic Fibrosis"

Background Nebulised hypertonic saline (HS) is an established basic airway clearance treatment in Cystic Fibrosis (CF). However, there is scarce evidence regarding the practical implementation and administration of different HS volumes, including physiotherapy and aspects of breathing pattern. The aim of the study was to implement standardised and age-adjusted nebulised volumes of hypertonic saline in cystic fibrosis patients, included in physiotherapy and lung drainage techniques.

Cystic Fibrosis is defined as a genetic disorder affecting approximately 100,000 individuals worldwide. CF is caused by mutations in the CF Transmembrane Conductance Regulator (CFTR) gene. CF patients are highly prone to environmental opportunistic bacterial infections leading to prolonged and chronic lung infections. This results in reduction in the life expectancy of CF patients due to excessive lung tissue destruction. Nitric Oxide (NO) is a naturally produced antimicrobial agent which is part of the innate immune defense system of the lung. Both in vitro and in vivo studies had shown clearly that NO acts against a wide variety of microbes including drug resistant bacteria as well as viruses and fungi. Building on a successful phase I safety trial, the team aims to develop a combined drug-device strategy to combat lung infections caused by biofilm-forming bacteria. Unlike other inhaled drugs, NO is also a smooth muscle relaxant and avoids the concomitant bronchial constriction often associated with inhaled antibiotics. An added benefit of NO therapy is its mucolytic activity. We suggest that the combine broad spectrum antimicrobial activity, signaling and mucolytic properties of NO, delivered to the lungs of CF patients, will be directed at reducing bacterial resistance, microbial burden and biofilms as well as resulting in improved airway clearance of viscid sputum. Primary Objectives: Assess the safety and the tolerability of NO intermittent inhalation treatment in ≥10 years old CF subjects. Secondary Objective: Assess the improvement in forced expiratory volume in 1 second (FEV1) before and after NO intermittent inhalation. Up to 10 subjects with Cystic Fibrosis will be enrolled into the study. Treatment administration: The subjects will receive intermittent inhalation of NO in addition to standard treatment for 10 working days (no NO treatment will be given to the subjects during weekend days). The subjects will be asked to attend the CF clinic once a week for a period of two weeks in order to evaluate the parameters related to the study. Oxygen (O2), NO, nitrogen dioxide (NO2) and fraction of inspired oxygen (FiO2) delivered to the patient will be continuously monitored.

The purpose of this study is to determine if the drug Plerixafor (Mozobil) can lead to clinically relevant efflux of CD117+ stem cells from the bone marrow to the peripheral blood of normal controls and patients awaiting lung transplantation. The investigator's hypothesis is that Plerixafor (Mozobil) will lead to significant mobilization of CD117+ stem cells to the peripheral blood.

The purpose of this trial is to compare the effects of treatment with tobramycin solution for inhalation (TIS) with and without azithromycin in people with cystic fibrosis (CF) age 6 months to 18 years who have early isolation of Pseudomonas aeruginosa (Pa) from a respiratory culture. Specimens of blood and sputum or throat swabs will be taken during the study along with pulmonary function testing. Participants will receive initial treatment with TIS followed additional treatment with TIS if quarterly respiratory cultures are positive for Pa in addition to either azithromycin or placebo for 18 months.

The primary objective of this study is to evaluate the safety and efficacy of a CAT regimen with aztreonam for inhalation solution (AZLI) and tobramycin inhalation solution (TIS) in adult and pediatric subjects with cystic fibrosis (CF) and pulmonary Pseudomonas aeruginosa (PA) infection. Participants will be enrolled in a 28 day TIS run-in phase, and will be eligible for randomization in the comparative phase if they have not received non-study oral antibiotics for a respiratory event, or IV or inhaled antibiotics for any indication between Visits 2 and 3, have not developed a condition requiring hospitalization or other change in clinical status which, in the opinion of the investigator would preclude their ability to continue in the study, and have demonstrated at least 50% TIS compliance. Participants enrolled in the comparative phase will be randomized to receive 3 cycles of treatment, each cycle consisting alternating regimens: AZLI or placebo for 28 days followed by TIS for 28 days.

The purpose of this study is to evaluate the efficacy and safety of ivacaftor in subjects with cystic fibrosis (CF) who have a non-G551D cystic fibrosis transmembrane regulator (CFTR) gating mutation (any one of the following CFTR mutations: G178R, G551S, S549N, S549R, G970R, G1244E, S1251N, S1255P, or G1349D).

Cystic fibrosis (CF) -- an autosomal recessive genetic disease affecting about 60,000 individuals worldwide, including about 3,800 in Italy -- is often associated with low bone mineral mass. The current aggressive therapies have ensured a much longer survival of CF patients but this has led to a higher frequency of osteoporosis and bone fractures, a serious problem which not only affects quality of life, but also hinders further therapeutic measures. The aim of this study, conducted on a large group of children, adolescents and young adults with CF, has been the evaluation of bone mass changes after 1 year of a simple treatment with RDA-adjusted dietary calcium plus 25-OH vitamin D supplementation, and the feasibility and efficacy of alendronate treatment (for another year) in patients not responding to calcium + 25-OH vitamin D alone.

It is hypothesised that inhaled mannitol 400 mg b.d. will lead to a significant improvement in the absolute change in percentage of predicted FEV1 from baseline following eight-weeks of trial treatment compared to treatment with inhaled placebo b.d. Any improvement in FEV1 is considered clinically meaningful; however, this trial has set a threshold of 3% for the purposes of determining an appropriate sample size for statistical power whilst retaining trial feasibility in an orphan disease population.

The purpose of this study is to evaluate safety and tolerability of VX-121 in healthy subjects and in subjects with cystic fibrosis (CF).

Cystic fibrosis (CF) is an autosomal recessive genetic disease characterized by recurrent airway infections, affecting many systems including lung, pancreas and sweat glands. Cough is an important defense mechanism for clearing the secretions that increase in respiratory diseases. There have been studies investigating the effect of expiratory muscle training on disease groups such as chronic obstructive pulmonary disease, multiple sclerosis, parkinson's disease, and the elderly and healthy individuals. Studies that evaluating effects of expiratory muscle training in cystic fibrosis are limited in the literature. The aim of this study was to evaluate the effect of cough strength in children and adolescents with CF and the effect of expiratory muscle training program on cough strength, exercise capacity, respiratory muscle strength and quality of life.
