NCT ID: NCT02993250 Completed - Clinical trials for Hepatitis C, Chronic

A Study to Investigate the Safety, Pharmacokinetics, and Efficacy of Combination Treatment of AL-335, Odalasvir, and Simeprevir in Japanese Participants With Chronic Hepatitis C Genotype 1 or 2 Virus Infection, With or Without Compensated Cirrhosis Who Are Direct Acting Antiviral Treatment-naive

Start date: December 21, 2016
Phase: Phase 2
Study type: Interventional

The main purpose of this study is to evaluate the safety and tolerability of a combination treatment of AL-335, odalasvir (ODV), and simeprevir (SMV) for 8 weeks in Japanese participants with genotype 1 or 2 chronic hepatitis C virus (HCV) infection without cirrhosis and for 12 weeks in direct-acting antiviral (DAA)‑naive Japanese participants with genotype 1 or 2 chronic HCV infection with compensated cirrhosis.

NCT ID: NCT02992457 Completed - Hepatitis C Clinical Trials

Safety and Efficacy of Sofosbuvir-Based Regimens in the Treatment of Egyptian Patients With Hepatitis C Infection

Start date: January 2015
Phase: Phase 4
Study type: Interventional

Egypt has the highest prevalence of hepatitis C virus (HCV) in the world, estimated nationally at 14.7%. Genotype 4 (and subtype 4a in particular) dominates the HCV epidemic in Egypt. For decades the antiviral therapy of chronic HCV infection was based on the administration of Interferon(IFN), initially alone and then in combination with Ribavirin (RBV), but this regimen was effective in only 50% of patients with genotype 1, with significant side effects.

NCT ID: NCT02991599 Completed - Hepatitis B Vaccine Clinical Trials

Immunogenicity of Hepatitis B Vaccination in Methadone Maintenance Treatment Patients

Start date: October 2014
Phase: Phase 4
Study type: Interventional

This is a randomized, controlled trial. The study will evaluate the immunogenicity, immune persistence, and safety of 20 µg and 60 µg recombinant hepatitis B vaccine with three injections at months 0, 1, and 6 in methadone maintenance treatment patients.

NCT ID: NCT02985450 Completed - Hepatitis B Clinical Trials

A Prospective Study of HBV Immunity and HBV Vaccination in Patients With NAFLD in Canada

Start date: August 2016
Phase:
Study type: Observational

(1) Due to missed childhood vaccination programs, the majority of adult patients with NAFLD in Canada do not have immunity to hepatitis B. (2) Adults with NAFLD who receive the HBV vaccine have reduced immunogenic responses in the setting of obesity (i.e., protective anti-HBs titres). Aims: (1) To determine the sero-prevalence of immunity against hepatitis B in a cohort of prospectively evaluated adult NAFLD patients. (2) To prospectively determine HBV vaccine responses (anti-HBs titres) in adult NAFLD patients.

NCT ID: NCT02982993 Completed - Clinical trials for Hepatitis C Infection

Hepatitis C Infection in World Trade Center Responders

Start date: December 2016
Phase:
Study type: Observational

This study provides Hepatitis C virus screening to the members of the World Trade Center Health Program followed at the Icahn School of Medicine at Mount Sinai born during 1945-1965, and linkage to care for those found infected. The study will also determine if exposure to human remains, blood and/or bodily fluids during the World Trade Center Health Program activities are associated with Hepatitis C virus infection. These findings would be relevant to the larger United States population, especially to persons born during 1945-1965 who are at high risk of Hepatitis C virus infection.

NCT ID: NCT02981602 Completed - Hepatitis B Clinical Trials

Safety, Tolerability, Pharmacokinetics and Antiviral Activity of IONIS-HBVRx in Treatment-Naïve Patients With Chronic HBV Infection

Start date: February 24, 2017
Phase: Phase 2
Study type: Interventional

To examine the safety and tolerability of IONIS-HBVRx administration to treatment-naive patients with chronic hepatitis B virus infection

NCT ID: NCT02979613 Completed - Chronic Hepatitis B Clinical Trials

Study to Evaluate Efficacy and Safety of Switching From TDF to TAF in Adults With Chronic Hepatitis B Who Are Virologically Suppressed

Start date: December 29, 2016
Phase: Phase 3
Study type: Interventional

The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of switching to tenofovir alafenamide (TAF) versus continuing tenofovir disoproxil fumarate (TDF) in virologically suppressed adults with chronic hepatitis B virus (HBV) infection.

NCT ID: NCT02972723 Completed - Clinical trials for Chronic Hepatitis C Infection

Metformin Therapy in HCV Infection

Start date: March 2011
Phase: Phase 4
Study type: Interventional

Hepatitis C virus infection (HCV) is a major cause of cirrhosis and death from liver disease worldwide. Current therapy for HCV with interferon based therapies results in cure rates of around 5055% which leaves a significant number of patients without effective therapy. HCV induces (can bring on) insulin resistance and insulin resistance is a factor known to reduce the response to antiHCV therapy. This finding stimulated initial studies looking at agents that may reduce insulin resistance as additional therapy in HCV infection. A study using metformin in addition to interferon and ribavirin showed a nonsignificant increase in cure rates (53% vs. 42%), but this was limited to patients with type 1 infection AND demonstrable insulin resistance. The assumption was made that the potential effect of metformin was likely to be on insulin resistance and thus by modulating this enhances response. The investigators (Prof M Harris, University of Leeds) have data (currently unpublished)suggesting that metformin may have an antiviral effect independent of its effect on insulin resistance, thus raising the possibility that metformin may have a direct antiviral effect in vivo. Given that the development of specific antiHCV agents which target viral proteins such as its polymerase and protease are in trial development but have so far proved either highly toxic or are likely to have a huge cost there is considerable rationale for looking at alternative potential antiHCV agents and in this context metformin is cheap, readily available and has an excellent safety profile. This pilot study therefore addresses the question "Does metformin therapy result in a significant drop in HCV viral load in chronically infected patients?"

NCT ID: NCT02971488 Completed - HIV Clinical Trials

The Impact on Linkage-to-care of an Alternative Hepatitis C Screening Method in PWID

Start date: January 15, 2017
Phase:
Study type: Observational [Patient Registry]

Screening, diagnosis and treatment of HCV in PWID, should be part of a harm reduction strategy. Treatment of HCV infected PWID should be delivered in a multidisciplinary care setting with services to reduce the risk of reinfection and for management of the common social and psychiatric comorbidities in this population. More frequent diagnosis, new methods that prevent loss of tracking, and access to antiviral treatment are all strategies that must be implemented jointly if the prevalence of HCV infection in our setting is to be reduced.

NCT ID: NCT02969668 Completed - Clinical trials for Hepatitis C, Chronic

Interferon-free Antiviral Treatment of Chronic Hepatitis C Virus Infection Among Opioid-substituted Patients

INFO
Start date: March 2016
Phase:
Study type: Observational [Patient Registry]

The primary objective of study will be to evaluate the effectiveness of interferon-free direct acting antivirals (IFN-free DAAs) in the treatment of chronic hepatitis C virus (HCV) among patients in opioid-substitution treatment (OST). We hypothesize that rates of sustained virological response will be comparable to non-OST populations. Secondary objectives include the evaluation of safety data, patients' adherence and patient reported outcome measures like functioning (disability), satisfaction with the treatment, health status, general health perceptions and health-related quality of life.
