Active clinical trials for "Cystic Fibrosis"

Human Neutrophil Elastase (HNE) plays a pivotal role in innate immunity and in neutrophilic lung inflammation that characterized many diseases. CHF 6333 is a potent and 24h-durable inhibitor of HNE, developed as Dry Powder Inhaler (DPI) formulation. This study is designed to investigate the tolerability, safety and pharmacokinetics of inhaled CHF6333 DPI in healthy male subjects. The study will comprise two parts: Part 1 will consist of two alternated cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Single Ascending Dose (SAD) of CHF6333. Part 2 will consist of four sequential cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Multiple Ascending Dose (MAD) of CHF6333

This clinical study is a phase IIa, multi-center, randomized, double-blind, placebo-controlled, parallel group study to evaluate two doses of orally administered GLPG2222 in adult subjects with a confirmed diagnosis of CF harbouring one F508del CFTR mutation and a second gating (class III) mutation and on stable treatment with ivacaftor. Up to 35 evaluable subjects are planned to be included in the study. Eligible subjects must be on stable treatment with physician prescribed ivacaftor (Kalydeco®) for at least 28 days at the baseline visit. They will be randomized in a 2:2:1 ratio to receive one of two active doses of GLPG2222 (150 mg q.d. or 300 mg q.d.) or placebo q.d. administered for 29 days. Subjects will be in the study for a minimum of 6 weeks and a maximum of 10 weeks, from screening until the follow-up visit.

This is a Phase 2, randomized, double-blind, placebo- and tezacaftor/ivacaftor (TEZ/IVA)-controlled, parallel-group, 3-part, multicenter study designed to evaluate the safety and efficacy of VX-659 in triple combination (TC) with TEZ and IVA in subjects with cystic fibrosis (CF) who are homozygous for the F508del mutation of the CF transmembrane conductance regulator (CFTR) gene (F/F genotype), or who are heterozygous for the F508del mutation and a minimal function (MF) CFTR mutation not likely to respond to TEZ, IVA, or TEZ/IVA (F/MF genotypes).

This is an 2-part study. Part 1 will assess the safety, tolerability and pharmacokinetics of single doses of FDL176 with and without co-administration of FDL169. Part 2 will assess the safety, tolerability and pharmacokinetics of repeated doses of FDL176 with and without co-administration of FDL169 .

An International Phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of LAU-7b administered once-daily for 6 months for the treatment of CF.

The goal of the study is to evaluate the safety and tolerability of P-1037 and to determine whether the combination of P-1037 with hypertonic saline or P-1037 alone has a greater effect on lung function in patients with CF than placebo (0.17% saline).

The lungs of most patients with cystic fibrosis (CF) become chronically infected with bacteria called Pseudomonas aeruginosa during childhood. This infection is now known to consist of free-living bacteria (known as "planktonic bacteria") and bacteria in colonies on body surfaces known as "biofilms". The bacteria in biofilms are more resistant and tolerant to antibiotics. Current CF treatment of exacerbations aims to eradicate or control pseudomonal infection using aggressive antibiotic regimes. Despite this treatment many patients develop chronic infection which is never cleared. Chronic infection causes damage to the lungs. Patients colonised with Pseudomonas are more unwell and die at a younger age. Our laboratory has established that low dose nitric oxide (NO) can disrupt pseudomonal biofilms in the laboratory. This pilot study will discover whether non-toxic levels of NO administered to participants during an episode of acute infection (exacerbation) will disrupt bacteria from biofilms and increase the effectiveness of antibiotic therapy. This protocol describes a participant-blind randomised controlled pilot study of treatment with nitric oxide gas during an acute infective exacerbation (also known simply as an "acute exacerbation"). Patients with CF aged 12 or above will be asked to take part. They will be randomised to receive 7 days either of inhaled nitric oxide gas or placebo alongside standard therapy during an exacerbation. Sputum samples will be obtained before, during and after the treatment period for microbiological analysis. The primary endpoint will be the microbiological effect on bacterial biofilms before and after NO adjunctive therapy. Secondary microbiological endpoints will include the between group differences in pseudomonal colony forming units (CFU"s), biofilm NO levels and detailed characterisation of biofilms before and after treatment. Secondary clinical endpoints will include lung function and well-established indicators quality of life. The aim of this randomised pilot study is as proof of concept and to guide the design of a large multi-centre trial to definitively evaluate the effectiveness of NO or NO donors as adjunctive therapy in CF.

This phase IV, multicenter, randomized, open-label, two-period crossover study will evaluate the comparable efficacy and safety of Pulmozyme (dornase alfa) delivered by the eRapid nebulizer system in patients with cystic fibrosis. Patients who have been receiving Pulmozyme once daily chronically for at least 6 months will continue to receive Pulmozyme once daily for a run-in period of 2 weeks using the Pari LC Plus nebulizer. Patients will then be randomized to receive in a crossover design Pulmozyme once daily for two treatment periods of 2 weeks each using either the Pari LC Plus or the eRapid nebulizer. Anticipated time on study treatment is 6 weeks.

The purpose of this study is to evaluate the long term safety and tolerability of Liposomal Amikacin for Inhalation (LAI) 590 mg once daily (QD) in Cystic Fibrosis patients with chronic infection due to pseudomonas aeruginosa. This long-term, open-label, multi-cycle extension study enrolled subjects who had successfully completed study TR02-108, were compliant with the study protocol, and did not meet any of the listed study discontinuation criteria. The safety and tolerability of LAI were evaluated for up to approximately 2 years.

Cystic fibrosis is a genetic condition where epithelial cells, including from the respiratory tract, have an abnormal function of a surface protein, the cystic fibrosis transmembrane conductance regulator (CFTR) protein resulting from abnormal gene expression. The trial will assess the clinical efficacy, safety & tolerability and gene expression following repeated nebulised doses of a gene product coding for a normal CFTR protein, with the primary outcome of the trial assessing lung function.
