Active clinical trials for "Hepatitis"

Hepatitis B virus (HBV) infection is a major public health threat in China. At present, a functional cure, also known as clinical cure or sustained Hepatitis B surface antigen (HBsAg) loss, is recommended as the ideal endpoint of HBV treatment. However, HBsAg loss can be achieved in less than 10% of chronic hepatitis B (CHB) patients treated with current available antiviral drug interferon (IFNα) or nucleos(t)ide analogues (NAs) monotherapy. With the support of the national major special funding for infectious diseases from "11th Five-Year Plan" to "13th Five-Year Plan", we have implemented a pioneer clinical study of sequential combination of IFNα therapy on NAs to treat NAs-treated CHB patients (ie. New Switch Study). This is the world's first clinical trial aiming to functional cure, which increased the rate of HBsAg loss to 15% in the overall population in our study, and to 30-50% among those with lower baseline HBsAg levels. How to further improve the HBsAg loss rate is an urgent issue for us. The key point of achieving functional cure is to reverse the HBV-specific T cell exhaustion and establish the long-term immune control against HBV infection. (Programmed death-1) PD-1/programmed death-ligand 1 (PD-L1) axis blockade has been demonstrated to reinvigorate exhausted CD8+ T cells, and would be a potential strategy to treat chronic HBV infection. In this study, a large multicenter prospective study will be performed to explore the safety and efficacy of a novel combination strategy involving immune checkpoint inhibitor (anti-PD-1 antibody) and IFNα in CHB patients, observe the HBsAg loss rate in NA-treated CHB patients receiving this combination strategy, evaluate the potential of breaking immune tolerance by this strategy, and further assess its efficacy to further improve the clinical cure rate on the basis of New Switch Study. Based on New Switch Study, this study further attempts to reverse T cell exhaustion in CHB patients, explore a novel platform of combination therapy development for clinical cure, and ultimately increase the HBsAg loss rate to higher than 50% in overall patients. The implementation of the project is expected to reduce the burden of HBV infection in China and contribute to the goal of global elimination of hepatitis B and C by 2030 (WHO 2030).

The goal of this study is to evaluate whether the standardized liver cancer risk stratification management can effectively improve the early diagnosis rate of liver cancer in the targeted risk population in China.

Clinical interventions to reduce the risk of vertical transmission of hepatitis C virus (HCV) infection from mother to infant are highly limited. Direct-acting antiviral (DAA) medications have demonstrated excellent safety and efficacy in non-pregnant individuals, but there is a lack of data regarding the safety of these medications in pregnant women and the effectiveness of these medications in reducing mother-to-child transmission. Therefore, although HCV screening during pregnancy is now recommended in many countries, there is no approved treatment for HCV during pregnancy. An observational study is here proposed to assess outcomes of mother-infant pairs exposed to DAAs during pregnancy within a global clinical case registry. Data regarding the exposures and outcomes of mother-infant pairs exposed to DAAs during pregnancy will be solicited and collected from clinical providers, healthcare facilities, HCV treatment programs, and other clinical practices worldwide. Data will be shared and maintained within a secure database, and cumulative data will be analyzed at pre-determined six-month intervals. The primary outcome will be the number and proportion of mother-infant pairs with adverse pregnancy or birth outcomes. The results of this study will inform HCV treatment decisions by clinical providers and programs worldwide.

Chronic hepatitis B seriously endangers the health of our people, especially the occurrence of HCC, which brings huge economic burden and life threat to our people. 84% - 92% of HCC in China is related to chronic HBV infection. How to further reduce the risk of liver cancer is an urgent problem to be solved in clinical research and an important direction. Although NAs treatment can make patients achieve the negative transformation of virus, it can not effectively reduce the level of virus antigen, and it also lacks the ability to improve the immune clearance of virus. As a result, the incidence of liver cancer in patients with long-term NA treatment is still 4.5% - 10.5%, and the incidence of HCC in patients with hypoviremia in Na treatment is higher. In current clinical practice, nearly 1 / 3 of patients treated with NAs can not reach the detection line of highly sensitive reagent. It is an important measure to make the patients with hypoviremia and inactive low virus replication treated by NAs below the detection line of highly sensitive reagent and further reduce the risk of HCC. However, it is still not enough to minimize the risk of HCC to achieve a complete viral response only through NA treatment. The long-term follow-up showed that the incidence of HBsAg disappeared by only 2.0% - 0.0% regardless of the long-term treatment of HBsAg. Therefore, the most important measure to minimize the occurrence of HCC is to optimize the treatment of NA treated patients with low virus replication and inactive patients with low virus replication to achieve complete virus response and clinical cure. The purpose of this study is to explore the optimal treatment scheme for chronic hepatitis B NA treated patients with hypoviremia and natural low virus replication patients to significantly reduce the risk of HCC.

This phase 2 trial aims to evaluate the efficacy of entecavir prophylacxis for hepatitis B virus (HBV) reactivation that continues until 12 months after completing CD20 monoclonal antibody therapy in patients with CD20-positive B-cell lymphomas and resolved hepatitis B (negative hepatitis B surface antigen, positive hepatitis B core antibody).

The purpose of this study is to explore the pathogenes, clinical characteristics, laboratory and histological examination results, treatment and prognosis of autoimmune hepatitis(AIH). At phase 1, the investigators focus on studying of the clinical characteristics of acute autoimmune hepatitis, and then will study the difference about treatment effects between acute autoimmune hepatitis and chronic AIH. Morever, the investigators have noticed that drug induced AIH have some special characteristics that may be beneficial to distinguish it with durg induced liver disease. Therefore the investigators will do some studies about drug induced AIH or other disease which maybe related to the onset of AIH.

The main aim of this study is to test in the Icelandic population the hypothesis that a nationwide treatment program which offers effective treatment to all known cases of Hepatitis C with the aim of halting HCV (Hepatitis C virus) transmission will lead to a reduction in incidence and disease burden associated with chronic HCV infection.
