Active clinical trials for "Hepatitis"

This is the first in human study of 162, and the primary objective is to evaluate the safety and tolerability of 162 with a single ascending dose in healthy adult subjects. The dose-escalation stage will be conducted sequentially at 5 dose levels, which are 100 mg in the pre-test, and 200 mg, 400 mg, 800 mg and 1200 mg in the formal test. Two healthy adult subjects will be enrolled at 100 mg dose level and all given 162. Eight healthy adult subjects will be enrolled at each remaining dose levels (200 mg, 400 mg, 800 mg and 1200 mg), respectively.

This study is a multi-center, double-blind, active-controlled, randomized, parallel clinical study to evaluate the efficacy and safety of DA-2803 in chronic hepatitis B subjects

To Identify the collected cases who can stop NAs safely with satisfactory clinical outcome including sustain viral remission and HBsAg clearance among chronic hepatitis B(CHB) patients.

Background: Chronic hepatitis C infects the liver. It may scar the liver. This is called cirrhosis and may lead to liver cancer or death. Current chronic hepatitis C treatments cure most people. But some keep getting complications even after it is cured. Researchers want to study why. Objective: To study the course and complications of liver disease after cure of hepatitis C infection. Eligibility: Adults 18 years and older infected with chronic hepatitis C virus who were never treated or were treated and not cured and those who were cured Design: Participants will be screened with: Blood and urine tests Questionnaires Liver ultrasound Fibroscan. A probe vibrates the liver, testing stiffness. In Phase 1, people with chronic hepatitis C will: Have a 3-day hospital admission to repeat some screening tests and have a liver biopsy. A small piece of liver is removed by needle passed through the skin. Take 1 tablet containing 2 hepatitis C drugs once a day for 12 weeks. Repeat some blood tests at 3 visits in those 12 weeks while on treatment, then 4 additional visits in the next 24 weeks with more blood work collected. Phase 1 participants who test negative for hepatitis C and all other eligible participants will enter Phase 2. Phase 2 participants will have a visit every 24 weeks for 10 years. These may include: Repeats of screening tests Questionnaires Scans Stool tests Chest x-ray Heart function test Endoscopy. A tube guides a camera into the upper digestive system. At about 5 years, participants will have another liver biopsy. Some participants will give separate consent for genetic testing and a special blood procedure....

In Chronic hepatitis B (CHB) patients receiving long-term sequential Neucleos(t)ides(NAs), majority of these CHB patients experienced drug resistance and switched to Tenofovir disoproxil fumaratate(TDF). However, some of patients on long term TDF experienced impairment of renal function and bone mineral density. After Tenofovir alafenamide(TAF) was in clinical practice, these group of patients got an clinical option to switch from TDF to TAF. The investigators designed a prospective cohort study to evaluate the real life effectiveness and safety in participants with chronic HBV infection switch from TDF to TAF vs. maintaining on TDF.

Evaluation the safety of using human umbilical mesenchymal stem cells to treat patients with hepatitis B cirrhosis. Observe the curative effect of patients with hepatitis B cirrhosis who use human umbilical mesenchymal stem cells to treat. Explore the possible mechanism of human umbilical mesenchymal stem cells to treat patients with hepatitis B cirrhosis.

Hepatitis C virus (HCV) infection is associated with significant morbidity and mortality owing to progression of a high percentage (85%) of HCV infected patients to chronic hepatitis, which might lead to the development of liver cirrhosis or hepato cellular carcinoma.. Egypt has possibly the highest HCV prevalence in the world, 10-20% of the general population .

After LT, long-term immunosuppressive therapy is required to prevent organ rejection. Therefore, for organs which may harbour OBI, there is a risk of reactivation which may result in liver graft failure. As a consequence, all patients who receive an anti-HBc positive graft will receive antiviral prophylaxis. Currently, all such patients will be commenced on life-long entecavir, which is highly effective in preventing reactivation.2 One major disadvantage of using such a blanket approach is that a significant proportion of anti-HBc donors may not actually have underlying occult HBV infection, and recipients of such grafts may not require lifelong antiviral therapy. Current markers such as HBsAg and HBV DNA are not sensitive enough to detect the presence of OBI. This is the first trial proposed to look at the efficacy of these novel HBV biomarkers in identifying occult HBV infection when used in combination, and to identify patients who will not need long term antiviral prophylaxis.

This is a multicenter, single arm study of Sofosbuvir/Velpatasvir (SOF/VEL) for treatment of chronic hepatitis C infection during pregnancy. Treatment will be initiated during the second or third trimester in approximately 100 pregnant people. Maternal participants will take one SOF/VEL tablet once daily for 12 weeks (84 days) and followed until 12 weeks after treatment completion (postpartum). Infants will be followed from birth until one year of age. The primary objectives are to evaluate the sustained virologic response 12 weeks after completion of SOF/VEL treatment (SVR12) in participants treated during pregnancy and to evaluate impact of antenatal treatment with SOF/VEL on the gestational age at delivery.

PD1 blockade has been approved as salvage therapy for advanced hepatocellular carcinoma (HCC). Although there is not solid evidence that PD1 blockade would induce hepatitis B virus (HBV) reactivation, previous clinical trials of PD1 blockade required enrolled patients to receive anti-HBV medications and control the viral load to be under 100-2000 IU/mL before initiation of PD1 blockade therapy. Such a requirement may not be necessary and could delay the treatment. Guidelines for prevention of chemotherapy induced HBV reactivation only suggest combining anti-HBV medications during the chemotherapy course without such a requirement of very load HBV viral load. The investigators hypothesized that under anti-HBV medications, patients with advanced HCC and active chronic hepatitis B virus (HBV) infection can receive durvalumab treatment without increased risks of HBV reactivation and related complications.
