Filter by:This is a Phase 2a, multi-center, placebo-controlled study in which patients with autoimmune hepatitis will receive zetomipzomib or placebo in addition to standard-of-care for 24 weeks; an optional open-label extension period allows patients to receive zetomipzomib (KZR-616) for an additional 24 weeks of treatment.
A retrospective, multi-center, non-interventional cohort study has been going to explore whether artificial intelligence can discriminate Drug-induced liver injury and Autoimmune hepatitis. A machine learning-based tool will be developed and validated to help clinicians to differentiate between Drug-induced liver injury and Autoimmune hepatitis
This study will evaluate the efficacy and safety of HR19042 capsules for the treatment of autoimmune hepatitis. It will also explore the optimal frequency and dosage of HR19042 capsules administration for the treatment.
Autoimmune hepatitis (AIH) is a chronic liver disease, which is characterized by the increase of immunoglobulin G (IgG) level, the presence of auto-antibodies and a typical histology, in the absence of other liver disease. Due to the heterogeneity of AIH manifestations, different scoring systems have been validated in order to make a reliable diagnosis. The two most recent scoring systems are: the revised International Autoimmune Hepatitis Group (IAIHG) criteria and the IAIHG simplified criteria. The second one is recommended by the European Association for the Study of the Liver (EASL) clinical practice guidelines (CPGs). The EASL clinical practice guidelines suggests that the treatment of ASAIH (Acute Severe AIH) is high doses of corticosteroids (superior to 1mg/kg/day) as early as possible and a lack of improvement within seven days should lead to listing for emergency liver transplantation (LT). However, the "lack of improvement" is not objectively defined and the grading of recommendation is III (Opinions of respected authorities). The hypothesis of the study is that the previously developed decisional score on a retrospective series will prospectively allow the differentiation between patients with ASAIH (Acute Severe AIH) who respond to corticosteroid therapy and should be maintained on treatment and patients who do not respond and should be rapidly evaluated for LT. The score will be computed at day 3 since corticosteroid introduction.
Rationale: The combination of azathioprine and prednisone is the first-line treatment for autoimmune hepatitis (AIH), a chronic inflammatory disease of the liver. Complete biochemical remission (CR) is the first treatment goal in autoimmune hepatitis. CR is determined by AST and ALT and IgG within the reference range. CR is not reached in a substantial proportion of AIH patients: after one year 50%, after three years around 20% did not achieve CR. Without CR ongoing hepatitis leads to progression towards fibrosis and eventually (decompensated) cirrhosis. Not achieving CR is the most important risk factor for the need for liver transplantation or liver related death, independent of age and presence of cirrhosis. Tacrolimus (TAC) and mycophenolate mofetil (MMF) are frequently used to prevent rejection in kidney and liver transplant patients. In AIH patients with insufficient response or intolerance to first-line therapy in retrospective cohort studies with MMF 0-57% and with TAC 20-95% CR was reached. Objective: The aim of this study is to compare the effectiveness of TAC with MMF as a second line treatment for AIH. Proportion of patients with CR after 12 months of treatment will be the primary outcome parameter to determine effectivity. Study design: Randomized open-label two arm study. Patients will be randomized between treatment with TAC or MMF. Study population: Patients with AIH with an incomplete response (no CR) to first-line treatment are eligible for this study. Intervention: In the TAC group baseline treatment will be replaced by tacrolimus. In the MMF group baseline treatment will be replaced by MMF. The current dose of prednisolone, or at least 5 mg daily, will be continued in both arms. After achieving CR prednisolone will be tapered according to protocol. Main study parameters/endpoints: Difference in proportion of patients with CR at 12 months (normalization of ALT, AST and IgG) between the TAC and MMF treatment group. Secondary parameters: - Safety and tolerability of TAC and MMF treatments - Difference in proportion of patients with CR at 6 months (normalization of ALT, AST and IgG) between the TAC and MMF treatment group. - Difference in ALT, AST and IgG at 6 and 12 months versus baseline - Difference in fibrogenesis and fibrosis parameters between groups and before and after treatment - Difference in quality of life between groups and before and after treatment
The aim of this study was to developed and validated models to predict hepatic decompensation and survivals in pediatric patients with cirrhosis and compared these models with currently available models.
Current standard therapy of primary biliary cholangitis-autoimmune hepatitis overlap syndrome(PBC-AIH overlap) consists of a combination of prednisolone and azathioprine. However, a significant proportion of patients may do not respond to, or is intolerant for azathioprine. Several studies have documented the efficacy and safety of mycophenolate mofetil(MMF) as second-line therapy for PBC-AIH overlap. However, robust evidence from a formal randomized clinical trial for the first-line immunosuppressor is in need.
The main objective of this study is to generate diagnosis and therapeutic-decision tools through the identification of molecular causes of PIDs with autoimmunity/inflammation and the variability in disease outcome at the transcriptional level using a combination of omics signatures (transcriptomics, epigenomics, proteomics, metagenomics, metabolomics and lipidomics).
The purpose of this study is to assess the strength and duration of the immunological response to COVID-19 vaccines in patients treated with immunosuppressive and/or immunomodulating medication for immune-mediated inflammatory diseases in rheumatology and gastroenterology and after a liver transplantation.
The primary objective of the study is to evaluate the effect of RO7049665 on time to relapse following forced corticosteroid (CCS) tapering as measured by the hazard ratio between RO7049665 7.5 milligrams (mg) and placebo arm.
