Active clinical trials for "Fibrosis"

The investigators aim to test the feasibility and effectiveness of a pre-meal snack to reduce the postprandial glycemia (PPG) excursion after a breakfast consumption in adult patients with cystic fibrosis (CF). The investigators also want to investigate the impact of a postprandial exercise to reduce the PPG excursion. An improvement in PPG excursions can improve the condition of CF patients primarily by delaying the onset of cystic fibrosis related diabetes (CFRD) and / or by reducing the risk of lung function loss.

This Phase 1/2a study is a double-blinded (subject and Investigator), randomized, placebo-controlled, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple nebulized doses of IONIS-ENaCRx.

The primary objectives of this study are to assess the safety and efficacy of MS1819-SD vs porcine pancreatic enzyme replacement therapy (PERT) in patients with exocrine pancreatic insufficiency (EPI) due to cystic fibrosis (CF).

Though the results of autologous CD34+ cell infusion and MSC in independent studies have shown promise, yet they are yet to reach the desired long term outcome. The possible postulation for this is possibly because when using autologous CD34+ cell infusion, the inflammatory milieu of the liver may not be conducive for sustained effects of the mobilized CD 34+ cells. MSC have immunomodulatory effect (ref) and may improve the liver environment making it more beneficial for the CD34+ cells to function and survive. In addition, MSC has ben shown to produce hepatocyte growth factor which is protective against liver injury and beneficial for liver regeneration (shown in above tables). However, it remains to be understood how MSCs promote liver stem stem cells to differentiate into hepatocytes or expand the residual hepatocyte population. MSC can also directly inhibit the activation of hepatic stellate cells, the main source of extracellular matrix via MSC derived IL 10 and TNF-αand may also induce hepatic stellate cell apoptosis. Current lacunae in cell based therapy is based on the poor consensus and understanding on the best type of cells to be used, the ideal number of cells, the most appropriate route of administration and the need for repeat dosing . The concept that combination of autologous hematopoietic and mesenchymal stem cells infusion may be more beneficial than infusing any one of them alone has been discussed in many scientific forums but there are no study till date to either see the safety as well as the efficacy of this proof of concept . With this above background data, we propose a study design which will be a safety study for combination use of autologous CD34+ and MSC

Cystic Fibrosis (CF) is the most common autosomal recessive lethal disorders affecting 1:2.500 newborns among Caucasians. CF patients are peculiarly susceptible to infection and colonization of the respiratory tract with pathogens. In particular, Methicillin-resistant Staphylococcus aureus (MRSA) has become the third most prevalent bacterium in CF in the U.S. and has been increasing in other countries. Apart from the difficulty of treating the infection because of its antimicrobial resistances, MRSA is transmissible between individuals with and without CF. Chronic MRSA infection is associated with worse outcomes, and treatment/eradication is challenging. Antibiotic dosing and choices should be optimized to minimize further resistance and to maximize chances of successful therapy. Yet, MRSA has several mechanisms to escape clearance by the immune system and antibiotic killing. For these reasons, a better understanding of preventive measures and early therapy is of key importance. In consideration of all these assessments there is an emerging consensus that MRSA is an important pathogen in CF rather than simply a marker of severe disease. However, to date there are no guidelines or recommendations on the choice of antibiotics for MRSA in CF. Glycopeptides are an important class of antibiotics active against Gram-positive pathogens. These include teicoplanin and vancomycin, which are currently in widespread use and are active against MRSA. Teicoplanin is often preferred to vancomycin for intravenous treatment because of its better safety profile but its use in MRSA lung infection is limited by its limited lung penetration. Teicoplanin is mainly used for injection/infusion. Inhalation of anti-microbial drugs is a cornerstone in the treatment of patients with CF, since inhaled antibiotics decrease the rate of decline of lung function, improve the quality of life, and reduce the frequency of exacerbations and hospital admissions. It is expected that, using inhalation route, efficacy would be improved and risk of resistance reduced. At present, no antibiotic active against MRSA is available as an inhaled formulation. The objective of this phase I, first-in-man clinical study is to identify the dose providing, after single inhalation administration, a sputum Teicoplanin concentrations exceeding the drug concentration required to inhibit bacterial growth for at least 8 hours, while minimizing the development of resistance.

A Phase III, Multicenter, open-labeded study to Evaluate Efficacy and Safety of TG-2349 in Combination With DAG181 and Ribavirin for 12 weeks of treatment in HCV Genotype I Infected Patients

This is a Phase 2 open-label, dose-escalation study to evaluate the safety, tolerability, PK, and PD of multiple dose levels of SC administered ELX-02 with and without ivacaftor in patients with CF with at least one G542X allele. In total, up to 16 patients will be enrolled in the trial; up to 4 patients will be homozygotes for G542X, and the remaining patients will be compound heterozygotes with one G542X or phenotypically similar nonsense allele and any Class 1 or Class 2 mutation. Each patient will receive up to 5 escalating doses as follows: ELX-02 0.3 mg/kg per day SC ELX-02 0.75 mg/kg per day SC ELX-02 1.5 mg/kg per day SC An individualized dose of ELX-02, as high as 3.0 mg/kg per day SC, based on the patients observed safety and tolerability, PK at previous doses and the results of laboratory tests. ELX-02 1.5 mg/kg per day SC plus 150 mg ivacaftor every 12 bid

According to previous studies, viral pneumonia can develop into pulmonary fibrosis, which can affect patients'lung function and even life health.This study aims to observe the efficacy and safety of Fuzheng Huayu Tablets in the treatment of pulmonary fibrosis after COVID-19.

This is a phase 1b multiple ascending dose escalation study to evaluate the safety and tolerability of arginase inhibitor CB-280 in subjects with cystic fibrosis.

Cirrhosis is a late stage of hepatic fibrosis caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. The World Health Organization (WHO) has reported that this condition accounts for 1.8% of all deaths in Europe (170,000 deaths/year). Patients with cirrhosis are characterized by severe metabolic alterations, which converge in a malnutritional state. Malnutrition encompasses glucose intolerance, chronic inflammation, altered gut microbiota, reduced muscle mass (sarcopenia), as well as loss and dysregulation of adipose tissue (adipopenia). Malnutrition is the most frequent complication that adversely affects the outcomes of cirrhotic patients. Yet, despite its clinical repercussions and potential reversibility, there are no effective therapies because our limited understanding of the mechanisms underlying this altered metabolism. β-hydroxy β-methylbutyrate (HMB) is a naturally produced substance regarded as safe and effective in preventing muscle loss during chronic diseases. Previous studies have indicated some beneficial effects of HMB itself or its parent metabolite, leucine, on adipose tissue, glucose intolerance, inflammation, and gut microbiota. This study aims to translate those beneficial effects to cirrhotic patients. The investigators hypothesize that HMB can improve cirrhosis-related metabolic abnormalities through its pleiotropic effects. The goals of this study are: i) to perform a randomized clinical trial to evaluate the efficacy of HMB, administered as nutritional supplementation, on clinical symptoms of cirrhosis. ii) to uncover the precise metabolic pathways that underlie HMB action, with a special focus on muscle, adipose tissue, and gut microbiota.
