582 Clinical Trials for Various Conditions
This is a Phase I double-blind, randomized, placebo controlled trial (1:4 ratio of placebo to vaccine) of Hepatitis E virus vaccine containing a 239 amino acid subfragment of Hecolin(R) (HEV-239) in 25 US males and non-pregnant females ages 18 - 45 (inclusive) to assess the safety, reactogenicity, and immunogenicity of HEV-239. Subjects will receive 3 doses of study product on Days 1, 29, and 180. Subjects will remain in the study for up to 13 months (including screening). The study duration will be approximately 15 months. Subjects will be observed for 30 minutes after vaccination. The occurrence of solicited injection site and systemic reactogenicity events will be measured from the time of study vaccination through Day 8 after each vaccination. These will be ascertained through use of an electronic memory (e-memory) aid, a telephone call on day 4 after each dose of vaccine, a Day 8 clinic visit, and potentially at the Day 15 clinic visit after each dose of vaccine. Unsolicited adverse events will be collected from vaccination through Day 29 after each vaccination. Serious adverse events will be collected from the time of the first study vaccination through the last study visit (Day 360). The study includes multiple phlebotomy time points for immunogenicity and blood collection for future use at visit 1 and Days 8, 15, and 29 after each vaccination. The durability of the immune response and future use collection will be assessed at 5 months after the first boost (Day 180) and at 6 months after the second boost (Day 360). The primary objectives of the study are to; 1) assess the safety and reactogenicity of HEV-239 following delivery of each vaccine dose; and 2) assess the number of subjects with \> / = 4 fold rise in Hepatitis E virus (HEV) immunoglobulin G (IgG) at any time after vaccination.
Background: - The hepatitis E virus causes an acute hepatitis that usually goes away by itself. Researchers in France studied people who received a liver or kidney transplant. They found that hepatitis E may not go away by itself in these people. It becomes chronic. This can cause serious liver disease. More than half the people who had organ transplant who had hepatitis E seemed to get a chronic infection. Researchers want to find out if hepatitis E happens this often in patients who have liver, kidney, or small bowel transplants in the United States. If it does, they want to know why. They want to know if chronic hepatitis E will become an important medical problem. This research might help improve care for people who have a transplant. It also might help researchers prevent the spread of hepatitis E. Objective: - To see how many patients who have received or are waiting for certain transplants have antibodies to hepatitis E virus. Eligibility: - Adults over age 18 who have had a liver, kidney, liver and kidney, or small bowel transplant, or are on a waiting list for one. Design: * Participants will be enrolled from 3 transplant centers. * Participants will complete a questionnaire. They will be asked about possible risk factors for hepatitis E exposure. * Participants will have a blood sample drawn through a needle placed in a vein.
This is a prospective, non-blinded cohort study that will assess the safety, tolerability, and antiviral efficacy of glecaprevir/pibrentasivir therapy given post-discharge to HCV-negative recipients of HCV infected donors. Patients who meet entry criteria will be enrolled while on the transplant waitlist. At the time of transplant, some donors will be HCV positive / NAT positive and some will not be infected. Enrolled patients who receive an HCV negative donor will serve as contemporaneous controls. All study subjects who receive an HCV positive organ will be confirmed to have acquired HCV infection and genotype will be assessed prior to treatment with therapy.
The purpose of this study is to evaluate the efficacy of a treatment regimen of JNJ-73763989 + pegylated interferon alpha-2a (PegIFN-alpha-2a) + nucleos(t)ide analog (NA).
The investigators' research is aimed at developing more effective, finite approaches for managing individual patients with chronic hepatitis B (CHB). This prospective clinical and basic scientific study exclusively focuses on patients with the early antigen negative form of disease, which in developed countries is treated indefinitely with antiviral drugs. The investigators' study "BeNEG-DO," directly offers patients who are already taking standard oral Hepatitis B Virus (HBV) antiviral therapy for at least 192 weeks the option to stop or continue treatment. Drawing on data from pilot studies, including the investigators' own University of California, San Francisco and Sutter Institutional Review Board-approved study, the investigators will examine a finite HBV treatment strategy on clinical outcome and safety. In conjunction, the investigators will study immunologic mechanisms and gene expression profiles that correlate with and predict the post-treatment clinical course. The BeNEG-DO study could seriously question, and potentially change, the current treatment paradigm for millions of patients with CHB and also lead to new disease-terminating antiviral therapeutics.
The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection.

This is an interventional, non-randomized, controlled prospective study to treat HCV in mono-infected and HIV co-infected individuals and compare cardiovascular risk outcomes to HIV mono-infected controls. This pilot study will demonstrate whether functional cure of HCV reduces myocardial injury and risk of cardiovascular disease.
Initially, HCV Informatics (C-IT) will be used to filter the EMR data of the one million people who receive care at Mount Sinai and identify candidates for HCV testing (baby boomers, patients with HIV infection) and candidates for HCV treatment (patients with positive test results for HCV RNA and no record of treatment).once treatment candidates have been identified through this proactive approach, their providers will be directly notified. HCV champions and patient navigators will be used to further lower barriers to the delivery of HCV care. They will be co-located at non-hepatology care sites and will help deliver open-label HCV treatment as part of standard medical care to 500 HIV/HCV co-infected patients and 200 patients with type 2 diabetes.
The goal of this study is to assess patients' attitudes and knowledge of Hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.

This randomized, controlled, parallel group, open-label multicenter study will evaluate the efficacy and safety of a combination of pegylated interferon alfa-2A (Pegasys) plus lamivudine or entecavir compared with an untreated control group in participants with HBeAg positive CHB in the immune tolerant phase. NOTE: STUDY RECRUITMENT HAS BEEN TERMINATED
The purpose of this study is to determine whether treatment with Daclatasvir/Asunaprevir/BMS-791325, with or without ribavirin, for 8, 6, or 4 weeks is feasible for the treatment of genotype 1a chronic hepatitis C in patients without cirrhosis.
Background: - Chronic infection with the hepatitis B virus may lead to cirrhosis, liver disease, and cancer of the liver. There is no cure for the infection, but several drugs have been approved to treat it. These drugs can keep the virus levels low. They seem to be safe for short-term use. But the drugs have not yet been approved for long-term use because some of them can have serious side effects. However, stopping treatment too soon can make the infection worse and may lead to more serious forms of liver disease. Researchers have not been able to determine a when to stop treatment. They want to study people with chronic hepatitis B infection to find out the best time to stop treatment and prevent the disease from causing further liver damage. Objectives: * To study the safety and effectiveness of withdrawing antiviral treatment for chronic hepatitis B after at least 4 years of treatment. * To determine whether stopping long-term antiviral treatment for chronic hepatitis B makes the infection worse. Eligibility: - People who are at least 18 years of age; have been taking antiviral drugs to treat chronic hepatitis B for at least 4 years; and are being evaluated to stop treatment. Design: * Those in the study will be screened with a physical exam, medical history, questionnaire, and blood tests. They will remain under the care of their regular doctor during the study. * They will have an abdominal ultrasound to study scarring in the liver, if they have not had one in the past year. * Those without detectable levels of the hepatitis B virus in their blood will stop antiviral treatment. They will have monthly blood tests for the first 6 months to check virus levels, and then every 3 months afterward. * Those whose blood tests show an increase in virus levels will restart antiviral treatment as directed by the study doctors and their personal doctor. * All those in the study will be monitored until the end of the study.
Open-label, extension study to evaluate the safety and efficacy of combination therapy and its effect on sustained viral response biomarkers.
Patients with chronic hepatitis B constantly produce the virus in the body. The disease of chronic hepatitis B is the body responding to the virus. Use of steroids can adjust this response. After taking steroids, viral production usually increases and liver function tests increase. After stopping steroids, viral production usually decreases. Many studies in the past have studied taking a low dose steroid before treating hepatitis B. Those studies have shown that low dose steroids help your body to clear the virus. The goal of this study is to improve the liver function by slowing viral growth.
Participants with chronic HBV infection will receive multiple doses of ARC-520 in combination with entecavir or tenofovir and be evaluated for safety and efficacy.
The purpose of the research is to determine if the Hepatitis B vaccine after birth provides enough protection after cooling for Hypoxic Ischemic Encephalopathy (HIE). To do this, Hepatitis B titers (blood sample) would be taken before, during, and after administering of the Hepatitis B vaccine series to measure efficacy of the vaccine.
Given the disproportionately high risk of chronic hepatitis C virus (HCV) infection in the baby boomer cohort, population-based screening has been demonstrated cost effective. Compared to point-of-care testing, however, bulk health messages with coupled lab requisitions delivered directly to patients meeting screening criteria via patient portals could improve HCV screening at minimal cost.
This is a preliminary trial of a Hepatitis B vaccine (Heplisav-B) in medically immunosuppressed patients. The purpose of this study is to test the ability of Heplisav-B to produce high levels of antibody that neutralize the virus and prevent hepatitis B from coming back. Another important purpose is to test the safety of this vaccine in patients taking immune suppressive medicines.
The main goals of the CARE-C study are to demonstrate the effectiveness of HCV models of care in a rural state (A) to overcome barriers to HCV treatment uptake, (B) to increase retention in care, and (C) to broaden access to care. To achieve these goals the following two systems interventions will be separately implemented: (1) Implementation of the Psychosocial Readiness Evaluation and Preparation for hepatitis C treatment (PREP-C) and related standard of care best practice PREP-C related interventions facilitated by a social worker-patient navigator team, and (2) implementation of a modified ECHO model (with one patient visit at specialty center to include PREP-C and fibrosis assessment in contrast to standard ECHO model). To test the effectiveness of our two systems interventions 600 patients will be equally distributed into three study arms representing 3 care models: Arm 1: Current Care Model (management with current interdisciplinary team); Arm 2: PREP-C Model (management with expanded interdisciplinary team (social worker, patient navigator, PREP-C); and Arm 3: Modified ECHO Model (management with expanded team in collaboration with community providers). An additional Arm 4 was started January 2021 to follow subjects experience with HCV management and treatment via telemedicine.
