Acute Liver Failure

Researchers are investigating the appropriate intensity of rehabilitation programs for patients who have undergone liver transplantation. Cardiovascular disease is a leading cause of death for these patients due to sedentary lifestyle and poor physical fitness after transplant. The study aims to test a structured, home-based, supervised physical rehabilitation and maintenance program in liver transplant recipients, assessing its feasibility, safety, and ability to improve physical fitness. Participants will be randomly assigned to one of three training groups with different exercise intensities low, moderate, or combined moderate and high intensity. The rehabilitation program lasts six months and includes aerobic, strength, balance, and flexibility exercises performed from home under supervision. After this, a 15-month maintenance phase of physical activity tailored to individual preferences will follow to observe long-term implementation. Participants will undergo assessments at the start, three months, six months, and 15 months after the intervention begins. These evaluations include tests of physical fitness, cardiovascular health, liver function, body composition, and questionnaires monitoring well-being, safety, quality of life, physical activity, and cost-effectiveness. Monthly monitoring of adverse events and follow-ups at the study site will ensure safety and track outcomes over time.

This research aims to learn more about vitamin C deficiency in patients with either acute or chronic diseases. It focuses on understanding how symptoms change over time and how well patients tolerate treatment. The study involves patients diagnosed with vitamin C deficiency either by lab tests or based on symptoms such as fatigue, infections, bleeding gums, joint pain, and poor wound healing. The study observes patients treated with Vitamin C Injektopas 7.5 g, given for an expected average of about 3 weeks for acute diseases or 12 weeks for chronic diseases. Two groups are included those with acute underlying diseases and those with chronic underlying diseases, both receiving this vitamin C therapy during the study period. Participants will be followed to assess changes in general and disease-specific symptoms, as well as treatment tolerability and overall effectiveness from the patients perspective. Researchers will also record the number of vitamin C infusions and measure quality of life for chronic disease patients. The study duration ranges up to approximately 12 weeks, with evaluations at the last visit to understand symptom improvement and treatment impact.

Researchers are studying the long-term risk of liver failure linked to TURALIO14 pexidartinib treatment in patients with symptomatic tenosynovial giant cell tumor TGCT who have severe symptoms or functional problems and cannot improve with surgery. This study also explores how liver damage happens by examining liver biopsy samples from patients who have or had liver toxicity while on TURALIO14. The goal is to understand liver injury mechanisms and assess safety over time. This is a non-interventional, observational study where no study medication is given. Participants have experienced liver test abnormalities from TURALIO14 treatment. Optional liver biopsies will be taken for detailed analysis of immune cells in the liver. Blood samples will also be collected to monitor liver function, safety, immune cells, and genetics. Participants will be followed yearly for up to 10 years to track liver health and potential failure after stopping TURALIO14. During the study, participants will provide blood samples and may choose to have a liver biopsy for further testing. Researchers will assess liver test results and monitor for signs of liver failure, liver transplant need, or death. Follow-up visits occur at least once per year for 10 years to observe long-term effects. The main outcome measured is how often liver failure occurs after stopping TURALIO14, helping to better understand long-term safety in this group.

Researchers are evaluating a new combined therapy using human albumin and enoxaparin in patients with decompensated cirrhosis who are discharged from the hospital. The study aims to determine if this combined treatment is safe, tolerable, effective, and whether it costs more or less compared to standard medical treatment. This Phase 2 clinical trial will compare patients receiving the combinatorial therapy plus standard care to those receiving only standard care to see how they respond over time. Participants are randomly assigned to one of two groups one group receives standard medical treatment along with the combined therapy of enoxaparin and human albumin, while the control group receives only standard medical treatment. The study involves treatment and follow-up over a period that includes monitoring at 30, 90, and 180 days after baseline to assess various health outcomes and complications. During the study, participants will attend visits where researchers will perform tests to track disease progression and response to treatment. Assessments include monitoring adverse events such as pulmonary edema, bleeding, and thrombocytopenia, as well as changes in liver and kidney function, hospital readmissions, survival rates, quality of life measures, and overall healthcare costs. Safety and tolerability are closely observed from baseline to day 90, with continued evaluation up to 180 days. Total study participation may last about six months from baseline.

Researchers are studying how the drug D-2570 is processed in the body and its safety in adults who have liver problems compared to those with normal liver function. This single-center, non-randomized, open-label study evaluates the pharmacokinetic profile of D-2570, focusing on how the drug moves through the body in different participants. The study includes adults aged 18 to 70 years, both with hepatic impairment and healthy liver function. Participants receive a single oral dose of D-2570 during the study. The study is organized into parallel groups, with participants with liver impairment enrolled first, followed by those with normal liver function. Researchers will monitor how the drug is absorbed, distributed, metabolized, and cleared, using blood samples collected up to 192 hours after dosing. During participation, individuals will undergo assessments to measure drug levels and safety, including monitoring for adverse events up to 9 days after dosing. The study tracks several key pharmacokinetic parameters such as time to maximum plasma concentration, maximum concentration, half-life, area under the curve, clearance, and volume of distribution. The entire study is expected to conclude by November 2026, with a primary completion date in October 2026.

Researchers are evaluating the safety, tolerability, and how the body processes pharmacokinetics two drugs, AZD9550 and AZD6234, in adults with different levels of liver impairment compared to those with normal liver function. This Phase I, open-label study includes participants with severe or moderate hepatic impairment as classified by the Child-Pugh score, as well as matched healthy controls. The goal is to understand how liver problems affect these drugs when given as single subcutaneous doses. Participants will receive separate single doses of AZD9550 and AZD6234 administered subcutaneously in two periods, with a washout period between the doses to reduce interference between drugs. The study groups include those with severe hepatic impairment Child-Pugh Class C, moderate hepatic impairment Child-Pugh Class B, and healthy individuals matched for sex, age, and body mass index. Approximately 16 participants with hepatic impairment and up to 12 healthy controls will be enrolled. During the study, participants will be assessed for drug levels in the body over 56 days after dosing to measure pharmacokinetic parameters such as AUCinf, AUClast, and Cmax. Safety and immune response will also be monitored through laboratory tests, vital signs, electrocardiograms, and adverse event reporting. The study duration includes screening, dosing periods, and follow-up visits to capture these outcomes under medical supervision.

Researchers are conducting a prospective, multi-center observational study in China to better understand drug-induced liver injury DILI. The study aims to explore the clinical features, identify the drugs or herbs causing DILI, assess patient outcomes, and discover new serum markers. The goal is to develop and validate a prognostic model incorporating these novel markers to improve prediction of patient prognosis in China. Participants will be grouped into a modeling group to help build a predictive model for DILI outcomes, and a validation group to test the accuracy of this model. The study collects long-term data to establish and verify these prognostic tools. No experimental treatments are given as this is an observational cohort study. During the study, researchers will monitor participants for key outcomes such as death, liver transplantation, and acute liver failure over one year, as well as chronic DILI and recovery over two years. Data will be collected through regular clinical assessments and laboratory tests. This long-term follow-up will help improve understanding of DILI prognosis and validate new serum biomarkers. Participants will be involved over extended periods to ensure comprehensive outcome measurement.

This research aims to understand patients with drug-induced liver injury DILI in various hospitals across mainland China, including Western medicine, Chinese medicine, integrated hospitals, and specialist hospitals for conditions like tuberculosis. The study focuses on evaluating the clinical characteristics, progression, and influencing factors of DILI in real-world clinical practice. It also seeks to learn about suspected drugs causing DILI, rechallenging, and patterns of liver biochemical abnormalities. The study is a multi-center, prospective, non-interventional cohort study that observes patients without providing experimental treatment. It involves different cohorts receiving standard care or treatments such as compound glycyrrhizin tabletsinjection, isoglycyrrhizinate magnesium injection, diammonium glycyrrhizinate capsules, bicyclol, silibinin capsules, ursodeoxycholic acid capsules, and N-acetylcysteine. The study will assess compliance with DILI guidelines, histological features, and specific populations including elderly and children with liver disease backgrounds. Participants will be monitored over time to observe disease progression including outcomes like death, liver failure, chronic DILI, or recovery within six months. Researchers will collect clinical data, liver function tests, and other relevant information to evaluate the course of DILI and factors affecting outcomes. The study will continue until December 2030, focusing on real-world data without altering patient treatment plans.

Researchers are investigating the use of 18F-DFA PET imaging to evaluate liver injury, a condition involving rapid liver function decline with symptoms like increased liver enzymes, jaundice, and abdominal discomfort. This observational study aims to assess how accurately this imaging method detects liver damage compared to standard clinical biochemical tests and liver biopsy, which is the current gold standard despite its sampling limitations. The study focuses on adults clinically diagnosed with liver damage or liver failure, exploring the correlation between 18F-DFA uptake in the liver and liver function indicators. Participants diagnosed with liver injury will undergo 18F-DFA PET imaging as part of the study. This radioactive tracer, based on vitamin C structure, is used to visualize liver function non-invasively. The imaging process involves a PET-CT scan lasting about 10 minutes, followed by a one-hour waiting period in the examination room before leaving. The study will compare imaging results with clinical liver function tests or liver biopsy findings to determine the sensitivity and specificity of this method. During the study, participants will have their liver function monitored using PET-CT scans and clinical biochemical markers. The primary outcomes include changes in liver uptake values on PET imaging at 6 months and the relationship between imaging results and standard liver function indicators. Participants will be followed up as needed, with assessments including liver enzyme levels and other blood tests. The total study duration depends on individual follow-up, and safety monitoring will address any issues related to PET imaging procedures.
