The Effects of Double Plasma Molecular Adsorption System in Acute on Chronic Liver Failure Patients

Acute liver failure patients posed high mortality rate despite receiving standard therapy. The severity and mortality even higher in patients with underlying liver disease. Acute liver failure cause hyperinflammatory response in early stage and immunoparalysis in later stage. The surge of proinflammatory cytokines leads to multiorgan failure and more liver injury. Subsequent immunoparalysis may lead to lethal secondary infections. Liver support system had been used in acute and acute ontop chronic liver disease for last several decades. Double plasma molecular adsorption system (DPMAS) is one of the promising non-biological liver support system that have been extensively investigated in acute ontop chronic liver failure from hepatits B viral. DPMAS circuit consist of BS330 (bilirubin adsorber) and HA330 (Cytokines adsorber). Thus, DPMAS can also remove various cytokines. The effect of DPMAS on immune function in these patients has not been explored. Recent randomized controlled trial by Srisawat et al. demonstrated improvement of mHLA-DR in septic shock patients who received polymyxin B extracorporeal therapy compare to control arm. Since liver failure show change of immunological profile resemble to sepsis. Investigators proposed that removal of toxic liver toxins and lethal cytokines by DPMAS will improve immunological profiles in acute ontop chronic liver failure patients. Investigators plan to conduct a randomized controlled trial in acute ontop chronic liver failure patients who admitted to intensive care unit. Investigators plan to compare the immunomodulatory effects of DPMAS with standard treatments.

Efficacy and Safety of Cytokine Adsorption and Plasma Exchange in Patients With ACLF and Sepsis

This study aims to evaluate the efficacy and safety of the double plasma cytokine adsorption system with sequential low-dose plasma exchange (DPCAS+LPE) in patients with acute-on-chronic liver failure (ACLF) complicated by sepsis. The focus is on assessing the impact of the cytokine adsorption column(CA280,Jafron Biomedical Co., Ltd., Zhuhai, China) on survival rates, inflammation markers, and organ function to determine its potential value in clinical practice. The primary research questions are: (1) Does DPCAS+LPE artificial liver therapy improve the 4-week mortality rate in ACLF patients with sepsis? (2) Does it improve the 12-week mortality rate in these patients? Additionally, the study examines the effects of this therapy on APACHE II scores, SOFA scores, vasoactive-inotropic score, MELD scores, and COSSH-ACLF II scores, as well as the cytokine adsorption efficiency of the CA280. Patients were randomly assigned to either the DPCAS+LPE group or the plasma exchange(PE) group. All patients received artificial liver therapy every other day, for a total of two sessions. Follow-up assessments were conducted before and after each therapy session, as well as at 1, 2, 3, 4, and 12 weeks.

Risk Factors Affecting MSC Efficacy in ACLF Patients

Mesenchymal stromal cells (MSCs) are potential therapy for many diseases, with the ability of tissue regeneration, repair and immunomodulation. Acute-on-chronic liver failure (ACLF) is a severe disease with high mortality. Previous studies showed that MSCs can improve the outcomes of Hepatitis B virus (HBV)-related ACLF patients. However, there are still some ACLF patients who have not benefited from MSC treatment. Thus, searching for risk factors affecting MSC efficacy in ACLF patients is of great significance for promotion of MSCs therapy. This retrospective study will perform at a single center in southern China. Consecutive HBV related-ACLF patients treated with MSCs at the Third Affiliated Hospital of Sun Yat-sen University from January 2010 to October 2018 will be included. The clinical data including survival status, liver functions, complications et al. will be collected and analyzed, with the purpose of identifying the risk factors of HBV-related ACLF patients received MSCs injection and improving the efficacy of MSCs therapy furtherly.

F573 for Injection for the Treatment of Liver Injury/Failure

This study was a randomized, double-blind, placebo-controlled PhaseⅡ clinical trial . The primary objective of this study was to evaluate the safety of F573 for injection in patients with liver injury (drug-induced liver injury (DILI), chronic hepatitis B (CHB), intrahepatic cholestatic liver injury, etc.).

Liver Transplantation in Patients With CirrHosis and Severe Acute-on-Chronic Liver Failure: iNdications and outComEs

Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as living-donor LT, should be explored. LDLT has impressive results in Eastern centers, but it is restrained in Western countries, due to potential life-threatening complications in the donor.

National Collaborative Centre for Hepatic Regenerative Medicine (NC-CHRM): Phase I Study on Safety and Efficacy of Mesenchymal Stem-Cell (MSC) Therapy in Non-Viral Acute-on-Chronic Liver Failure (ACLF)

Liver disease deaths are rising, but transplants remain scarce in India. With over 100,000 needed annually and only \~2,500 performed, non-transplant options are urgently needed. Regenerative therapy, especially MSCs, shows promise but lacks validation, particularly for non-viral Acute on Chronic Liver Failure (ACLF). The proposed NC-CHRM aims to develop and validate MSC-based therapy to promote native liver regeneration and offer a safe, effective, transplant-free treatment.

A-TANGO Phase 2 Study

The purpose of this research is to know if a new combination of drugs (TAK-242 and G-CSF) in combination with standard therapy for acute-on-chronic liver failure (ACLF) is more effective than standard therapy for ACLF treatment and is safe. Description of the population to be studied: ACLF is a syndrome that occurs in patients with chronic liver disease, with or without previously diagnosed cirrhosis, which is characterized by acute hepatic decompensation. Cirrhosis is a chronic disease of the liver marked by degeneration of cells, inflammation, and thickening and scarring (fibrosis) of liver tissue. Hepatic decompensation is a sudden decline in liver function. It is characterized by severe liver damage and complications like jaundice (yellowing of the skin or whites of the eyes), ascites (a condition where excess fluid accumulates in the abdominal cavity and in abdominal organs) and encephalopathy (a group of symptoms that result from damage or dysfunction in the brain, causing a range of cognitive and neurological impairments). It may result in liver failure, one or more organ failures other than liver (renal, brain, coagulation, respiratory, cardiovascular), and is associated with increased mortality within 28-days and up to 3 months from onset. Grade 1 ACLF has a \>15% risk of mortality at 28 days. Purpose of the study: The investigational medication, TAK-242, is aimed at stopping an "over-reaction" of the immune system (the body's defense system) while G-CSF encourages your liver cells to grow. In patients with severe inflammation of the liver due to alcohol \[severe alcoholic hepatitis (sAH)\] and ACLF, this over-reaction may cause the liver and other organs in the body to suddenly stop working (organ failure). The hypothesis of the study is that by blocking this over-reaction and encouraging your liver cells to grow your condition may improve.

Comparison of Blood Products Required Using Two Different ROTEM Cut-offs Before Invasive Procedures in Cirrhosis and Acute on Chronic Liver Failure (ACLF) Patients With Severe Coagulopathy

Coagulation system in cirrhotics patients is a fragile state , which is rebalanced hemostasis. Standard tests (INR/aPTT) stop measuring at first stage of coagulation ,when the clot first form. VETs measure the whole process such as ROTEM, TEG and comparing these two tests to assess for transfusion of blood products for invasive procedures. . ROTEM provides information both on anti coagulant and procoagulant status where as conventional tests provide only anti coagulant status Invasive procedures can be low risk or high risk or Non surgical vs surgical, Procedure related bleed occurs in 7% of patients with cirrhosis and associated with higher 28 day mortality. MELD, CTP ,AKI , SEPSIS increase the risk of procedure related bleed. Hence for invasive procedures investigator is using relaxing threshold for blood product transfusion in cirrhosis, ACLF patients. As use of ROTEM when compared to conventional tests reduces the need for blood transfusion. Investigator want to proceed with further relaxation of cutoff values of Coagulation parameters and use High cutoff vs low cut off for blood transfusion need.

The study will enroll patients aged 18 to 65 years who meet the diagnostic criteria for acute-on-chronic liver failure as outlined in the 2024 Chinese Liver Failure Clinical Guidelines. The main questions this study aims to answer are: * Does the combined therapy improve the 28-day survival rate after the final treatment? * Does the QH-1A device in its HBAL mode consistently achieve the predefined device performance pass rate? * Do patients show significant improvements in their biochemical markers following treatment? * What is the immunogenicity profile of the mesenchymal stem cells used for blood purification? Participants will be screened within 14 days before their first treatment and will be allocated into one of four groups based on treatment duration and frequency: * 4-hour group (3 patients) * 6-hour group (3 patients) * 8-hour group (3 patients) * Multiple-treatment group (6 patients) Treatment will be administered in a sequential escalation-from the 4-hour group up to the multiple-treatment group-based on safety data from a 28-day observation period, which will be reviewed by a Safety Evaluation Committee. In addition, upon referral to the Hepatitis B Health Clinic, participants will receive tailored health education, comprehensive liver function and virological assessments, and an individualized treatment and follow-up plan.

Chinese Phase II Trail of AS1501 in Acute-on-chronic Liver Failure (ACLF) Patients

\*\*Document Name: This Trial is a Phase II Clinical Study.docx\*\* \*\*Document Content:\*\* * This trial is a Phase II clinical study, conducted in two stages: * \*\*Phase IIa:\*\* A sentinel, single-arm design will be employed. A total of 12 early ACLF subjects are expected to be enrolled in the 0.5 mg/kg dose group. The first 2 subjects will serve as sentinels and be enrolled sequentially to receive a single intravenous dose. If no drug-related SAEs (Serious Adverse Events) occur in these 2 sentinel subjects within 2 weeks after the first dose, the remaining 10 subjects will be enrolled. Otherwise, the dose will be reduced for further exploration. After receiving a single intravenous dose, subjects will undergo a 20-day washout period. If no drug-related ≥Grade 3 AEs (Adverse Events) occur during this 20-day washout period, and safety/tolerability is jointly confirmed by the investigator and sponsor, the subject will enter the multiple-dose phase (once weekly \[Day 21 as the first dose of multiple administration\], for 4 consecutive weeks). If any drug-related ≥Grade 3 AE occurs, the dose will be reduced for further exploration, with the specific dose determined by the sponsor and investigator. If a subject drops out during the washout period after a single dose, additional subjects may be enrolled to ensure at least 12 subjects enter the multiple-dose phase. * After all 12 early ACLF subjects in the 0.5 mg/kg dose group complete continuous dosing, the DMC (Data Monitoring Committee) will assess the safety of this dose group. If any of the following occur in the 0.5 mg/kg group, the DMC will discuss whether to proceed with dose escalation: \> 1) ≥1/3 of subjects experience drug-related Grade 3 SAEs; \> 2) Any drug-related Grade 4 or higher SAEs. * If the DMC determines that dose escalation criteria are met, an additional 12 early ACLF subjects will be enrolled to receive the 1 mg/kg dose group. The same enrollment rules as the 0.5 mg/kg group apply: the first 2 subjects are sentinels receiving a single intravenous dose. If no drug-related SAEs occur in these sentinels within 2 weeks post-dose, the remaining 10 subjects will be enrolled. Post-single-dose administration, subjects will undergo a 20-day washout period. If no drug-related ≥Grade 3 AEs occur during this period, and safety/tolerability is confirmed, subjects will enter the multiple-dose phase (once weekly \[Day 21 as the first dose\], for 4 consecutive weeks). Dropouts during the washout period may be replaced to ensure at least 12 subjects enter the multiple-dose phase. * After completing the 0.5 mg/kg and 1 mg/kg dose exploration studies, the investigator and sponsor may determine the recommended dose for Phase IIb based on cumulative safety, efficacy, and potential PK/PD results. Additional dose groups or alternative administration frequencies may also be explored. * \*\*Phase IIb:\*\* A randomized (1:1), double-blind, placebo-controlled design will be used. A total of 72 ACLF subjects are expected to receive either AS1501 at the appropriate dose/frequency or placebo to further evaluate the efficacy and safety of AS1501 injection. The specific design will be finalized based on Phase IIa results and agreed upon by the investigator and sponsor.

Umbilical Cord-derived Mesenchymal Stem Cell Infusion for Treating ACLF

This study is a multicenter, randomized, double-blind, placebo-controlled adaptive design Phase IIb/III clinical trial. It employs a seamless adaptive design, divided into Phase IIb and Phase III, focusing on patients with acute-on-chronic liver failure (ACLF). Eligible patients meeting the inclusion criteria and not disqualified were randomized in a 2:2:1:1 ratio during Phase IIb to receive either a high-dose experimental group (4.0×10\^6/kg of injectable mesenchymal stem cells derived from umbilical cord), a low-dose group (2.0×10\^6/kg), a high-dose placebo control group (with equivalent volume of solvent calculated at 4.0×10\^6/kg), or a low-dose placebo control group (with equivalent volume of solvent calculated at 2.0×10\^6/kg). In Phase III, patients were randomized in a 1:1 ratio to the experimental group (injectable umbilical cord-derived mesenchymal stem cells) or the control group. All groups received standard treatment alongside either the experimental drug (experimental group) or placebo (control group) to evaluate and confirm the efficacy and safety of injectable umbilical cord-derived mesenchymal stem cells in treating acute-on-chronic liver failure.

Comparison of Efficacy and Safety of Ceftazidime Avibactam Versus Extended Infusions of High Dose Meropenem in Patients of ACLF With Nosocomial Infections.

Acute on chronic liver failure patients are at high risk for nosocomial infections due to liver dysfunction, which impairs immune responses and increases vulnerability to infections. Key factors contributing to nosocomial infections in ACLF patients include ascites, use of invasive devices, and recent hospitalization, frequent need for broad spectrum antibiotics. Multidrug resistance is a growing issue, making treatment more challenging, common pathogens involved are gram negative bacteria such as Escherichia Coli and Klebsiella pneumoniae. Surveillance data show increasing carbapenem resistant enterobacterales (CRE) infection rates in cirrhotics, with high morbidity and mortality rates. The impact of these nosocomial infections is profound, significantly worsen outcomes in ACLF patients, leading to prolonged hospitalizations, increased health care costs and higher mortality rates. Early detection and effective antibiotic stewardship are essential to manage antibiotic resistance and improve patient outcomes. In this study we aim to compare efficacy and safety of Ceftazidime avibactam versus extended infusions of high dose Meropenem in patients of ACLF with nosocomial infections.

To Optimize Therapeutic Procedures of DPMAS in ACLF Patients: a Prospective, Sigle Arm and Multicenter Study

Acute-on-chronic liver failure (ACLF) is a life-threaten syndrome carrying high-short-term mortality raging 40% to 60% within 90 days in patients with chronic liver disease. Double plasma molecular adsorption system (DPMAS) is one of the available artificial liver support systems, which combines plasma filtration and two specific adsorption membranes dedicating to remove bilirubin and the middle molecular toxins respectively. The efficiency of DMPAS treatment in liver failure patients remains controversial. Previous study indicate that liver failure patients with DPMAS therapy improve the short-term mortality and prevent the diseases progression within 28 days (PADSTONE Study). Thus, this single-arm, multicenter and prospective study is to further validate and optimize the therapeutic procedures of DPMAS therapy in ACLF patients.

Acute on Chronic Liver Failure in Cirrhotic Patients at Assiut University Hospitals

ACLF is a distinct syndrome that is different from chronic progressive hepatic decompensation. In most cases of ACLF, patients present initially with clinical manifestations of a decompensating event, usually renal impairment, worsening of abdominal ascites, jaundice or Hepatic encephalopathy (HE) and often precipitated by bacterial infection.
