NCT ID: NCT03908255 Not yet recruiting - Clinical trials for Hepatocellular Carcinoma

Branched-chain Amino Acid Supplementation for Hepatocellular Carcinoma

BCAA in HCC
Start date: April 1, 2019
Phase: Phase 2
Study type: Interventional

Hepatocellular carcinoma (HCC) is the fifth most common cause of cancer death among men. While several new treatment options have recently become available, they are costly and have a potential for significant, adverse side effects. Many patients diagnosed with HCC also suffer from underlying liver disease, including cirrhosis. As many as 80-90% of patients diagnosed with HCC also have cirrhosis. Protein-energy malnutrition (PEM) in cirrhosis is as high as 65-90% and significantly increases the risk of morbidity and mortality as well as decreased quality of life. Branched-chain amino acid (BCAA) supplementation has been extensively studied for usefulness in liver disease, specifically to treat hepatic encephalopathy to and preserve and restore muscle mass. Maintenance of liver function and prevention of PEM are essential for improving outcomes in patients with HCC. Branched-chain amino acid supplementation in HCC has been studied extensively in China & Japan with multiple studies showing improvements in liver function, progression-free survival, and overall survival. Additionally, patients in treatment groups have shown improvement in quality of life indicators. However, these results have yet to be replicated in the United States. Branched-chain amino acid supplementation may be a safe, low-cost approach to improve survival, liver function indicators, and quality of life for patients diagnosed with HCC. In this study, patients with primary HCC will be randomized to either a treatment group, which will receive standard of care and BCAA supplement or to a control group which will receive standard of care and a maltodextrin placebo. Both groups will receive liver-directed therapy including transarterial chemoembolization (TACE) and thermal ablation. All patients will complete a quality of life survey (FACT-Hep) at each visit.

Study of microRNAs in a Decompensated Cirrhosis

EmiC
Start date: May 1, 2019
Phase:
Study type: Observational

Cirrhotic patients are at higher risk of sepsis due to impaired innate and adaptive immune responses. Septic complications represent a major issue in the management of cirrhotic patients, with a 1-month mortality rate of 23%, which increases to 80% at 3 months in case of associated organ failure. Delay to treatment initiation during a septic episode may increase the risk of complications and mortality of cirrhotic patients. However, the inappropriate use of antibiotics exposes cirrhotic patients to the risk of more severe infections due to multi-resistant organisms or fungi. The use of diagnostic markers for sepsis is limited in the context of cirrhosis because of the lack of hepatic synthesis of these markers on the one hand and non-specific inflammation related to cirrhosis on the other hand. Therefore, it is necessary to develop new tools for the early diagnosis of sepsis and appropriate management of cirrhotic patients. The interest of microRNAs (miRNAs) in the diagnosis and prognosis of septic shock has been reported in the general population. No studies have described circulating miRNAs or reported their interest in the diagnosis of sepsis in a population of cirrhotic patients with acute decompensation (AD). This preliminary study of 800 circulating miRNAs will be performed in a cohort of patients with acute cirrhosis decompensation, for whom the incidence of sepsis is estimated at 40%. The aim to evaluate the interest and feasibility of a larger study on the interest of circulating miRNAs in the early diagnosis of sepsis in cirrhotic patients. The long-term objective of this study is the development of biomarkers for the early management of cirrhotic patients with sepsis and the rationalization of antibiotic use to improve their prognosis.

Functional Assessment in Liver Transplantation

FrAILT
Start date: October 6, 2015
Phase:
Study type: Observational

In order to ensure the equity of the liver allocation process, it is important to create objective, scientifically validated markers of frailty in patients with end-stage liver disease that accurately predict patient outcomes. Many measures have been developed to assess this clinical state in elderly patients, but none have been applied to patients with cirrhosis, a population at increased risk for accelerated functional decline. This protocol is designed to learn more about the effects of functional status (also known as "frailty") in liver transplant patients and patient outcomes both before and after liver transplant.

Probiotics in the Prevention of Hepatocellular Carcinoma in Cirrhosis

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

Background. The main risk factor for the development of hepatocellular carcinoma (HCC) is cirrhosis of any etiology, with an annual risk between 1 and 6%, being currently the leading cause of death in patients with cirrhosis and the third cause of death for cancer in the world. In our country there is little information about the incidence of HCC in this population. It has been shown that there is a change in the gut microbiome (set of genetic material of microorganisms that make up the intestinal bacterial flora) as the severity of the cirrhosis progresses. This change in the microbiome has been associated with clinical decompensation events of cirrhosis. However, there are no previous studies in the world that demonstrate an impact of the change of the microbiome in cirrhosis as a precursor to the development of HCC. Our team has compared the profile of the microbiome in patients with cirrhosis with and without HCC. We observed that patients with HCC present changes in the phylum Firmicutes, genus Fusobacterium and change in the bacteroides / prevotella ratio. This pattern was associated with a pro-inflammatory profile. In murine models, it has been postulated that modulation of the gut microbiome through the use of probiotics could have a clinical role in the prevention of HCC development. This research project aims to answer the following question: in patients with cirrhosis, does the nutritional supplement with probiotics prevent HCC development? Objective: To compare the incidence of HCC through intervention with probiotics in cirrhosis. Methods: A randomized, double-blind, placebo controlled trial of probiotics in patients with Child Pugh A-B cirrhosis at 3-year follow-up. Likewise, the type of microbiome found as a predictor of the risk of HCC development will be evaluated. It will include 280 patients, 140 in each branch. Basal blood and stool samples will be obtained and every 6 months. The typing and quantification of the microbiome in samples of fecal matter will be carried out by amplifying a specific region (V3-V4) of the bacterial 16s rRNA gene. Likewise, the presence of endotoxins (LPS) and cytokines (IL6, TNF alpha) in plasma will be determined to analyze the immune environment and the expression of the TLR4 receptor in mononuclear cells.

Microvesicles and Monocytes to Predict Mortality of Patients With Cirrhosis

PROMICE
Start date: March 15, 2019
Phase:
Study type: Observational

Chronic liver diseases related to viral hepatitis, metabolic syndrome or excessive alcohol consumption can evolve towards cirrhosis. Cirrhosis is responsible for 170 000 deaths per year in Europe. Initially asymptomatic and called "compensated" it can become"decompensated" with the developpement of acute complications such as infections, ascites or variceal bleeding. The transition from compensated to decompensated cirrhosis is associated with a reduction in survival from 95 to 55% at 1 year. The only curative treatment for cirrhosis is liver transplantation (LT). Liver transplants are allocated according to the severity of the patients. Despite a modest prognostic value (area under the ROC curve = 0.7 to predict the risk of death), graft allocation is based on the MELD (Model for End-Stage Liver Disease) score including INR, bilirubin and serum creatinine. In 2014, 11.5% of registered patients died on the liver transplant waiting list, illustrating the need for biomarkers that predict death and improve MELD-based prediction. Microvesicles are membrane vesicles released in extracellular space during cell activation or apoptosis. Our team showed that circulating levels of hepatocyte microvesicles increase with the severity of cirrhosis and predict survival at 6 months independently of MELD score in a cohort of 242 patients with cirrhosis. Type 1 interferons (IFN-1) are mediators of inflammation, which is excessively activated in cirrhosis. Our team has shown that a gene signature (IFN score) measured in the immune cells of 101 patients with cirrhosis is able to predict 6 month-survival independently of the MELD score. Thus, the investigators hypothesize that a composite score combining the level of circulating hepatocyte microvesicles, the IFN score and the MELD score could improve the prediction of survival in patients with severe cirrhosis. The aim of this study is to compare the prognostic performance for the cumulative incidence of death at 6 months of a composite score including MELD, hepatocyte microvesicle level and IFN score with that of the MELD score alone, in patients with Child B or C cirrhosis, considering liver transplantation as a competitive risk. To address this question, peripheral blood from 335 patients with Child B or C cirrhosis will be obtained and hepatocyte microvesicle levels and IFN score will be measured using ELISA/filtration and Real Time-quantitative PCR.

A Study Evaluating the Utility of Ambrisentan in Lowering Portal Pressure in Patients With Liver Cirrhosis

Start date: April 11, 2019
Phase: Phase 2
Study type: Interventional

Endothelin is a human hormone which has been associated with increased portal pressure in patients with liver cirrhosis (also called portal hypertension). Ambrisentan blocks the effects of endothelin. The purpose of this study is to evaluate the effect of ambrisentan on portal pressure and renal function in patients with advanced liver cirrhosis and with portal hypertension. In this study, portal pressure will be determined at multiple times with the aid of a catheter inserted into the body of the patient. The effect of ambrisentan on the function of the kidney will also be investigated. This study will also evaluate the concentrations of ambrisentan in blood in patients with liver cirrhosis.

FMT in Cirrhosis and Hepatic Encephalopathy

Start date: April 30, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Patients with end stage of liver disease or cirrhosis can develop confusion due to high ammonia and inflammation. This confusion is brought upon by changes in the bacteria in the bowels and may not respond to current standard of care treatments. Repeated episodes of confusion can make it difficult for patients to function and may result in multiple admissions to the hospital and burden on the family. The investigators have studied using a healthy person's stool to replace the bowel bacteria, called fecal microbial transplant, in small studies with good results. In this trial the investigators propose to perform these procedures using an upper and lower route in Veterans who suffer from this condition and follow them for safety and hospitalizations over 6 months. The investigators will compare this to placebo treatments and hope that this intervention can improve the health and daily functioning of affected patients.

A Prospective Study to Monitor Liver Diseases Dynamically by Ultrasound Viscoelasticity

Start date: January 1, 2019
Phase: N/A
Study type: Interventional

The accuracy of ultrasound elastography for assessing liver fibrosis by measuring liver stiffness (elastic modulus) is better than traditional method. Elastography has certain advantage such as non-invasive, simple, real-time and it has been recommended by clinical guidelines. However, some chanllenging scientific problems showed up with further research and clinical practice. Firstly, present elastography machines can only calculate liver stiffness from shear wave speed or elastic modulus but ignore other physical characteristics such as tissue viscosity. So far, present technique simply assume liver as an idealized model with isotropic elasticity to assess liver fibrosis while liver is actually anisotropic and viscoelastic. What's more, theoretically, there are not only different solid state structures such as cell organization and vessel but also flowing liquid such as blood and bile. Thus, ignoring viscosity and evaluating elasticity only is unreasonable. In the other hand, a number of confounding factors have been found to influence liver stiffness measurement by elastography. Different pathological chang of liver including inflammation, necrosis, cholestasis and inhomogeneity among the individuals such as obesity, ascites, et,al. will decrease the accuracy of liver stiffness measurement and liver fibrosis staging by elastography. In fact, liver fibrosis is a dynamic process. Liver fibrosis is a reaction of compensation and repair for inflammation and necrosis as well as a contributing factor for liver damage. This dynamic process constitutes the common characteristic of chronic liver disease and result in the complicated biological mechanical characteristics of liver. In consequence, how to measure liver viscosity and elasticity respectively, and to evaluate liver fibrosis stage and Inflammation degree accurately during the complicated and dynamic pathological process is the key scientific problem demanding solution, which is also the urgent requirement of related fundamental research and clinical practice. Therefore, this project plan to apply LOGIQ E viscoelastography machine as research tool, rat liver fibrosis model and rat liver failure model as research object to investigate the correlation between liver viscoelastography measurement and liver fibrosis stage and Inflammation degree. The investigators also aim to assess the feasibility of using ulstrasound viscoelastography to evaluate liver fibrosis stage and Inflammation degree dynamically.
