Filter by:This study will assess the effect of treatment for hepatitis C virus (HCV) on cardiovascular disease risk. The study will enroll men and women who are infected with HCV and have underlying metabolic disease. All participants will receive a 12-week course of an HCV treatment (elbasvir/grazoprevir). Cardiovascular disease risk will be evaluated at baseline, week 4 on treatment, 12 weeks post-treatment, and 52 weeks post-treatment through noninvasive measurements of endothelial function, insulin resistance, liver fibrosis and steatosis, and circulating blood biomarkers.
Background: Hepatitis B is a viral infection of the liver. When the immune system tries to clear hepatitis B, it damages the liver. Eventually, the immune system gets exhausted fighting the virus. Researchers want to see if giving large doses of an antibody (HBIg) with the drug peginterferon will boost the immune system in people with this disease. Objectives: To observe the effect of large doses of antibody against the hepatitis B surface antigen on the immune response to the virus. To see if removing hepatitis B surface antigen from the blood enhances the action of peginterferon. Eligibility: Adults ages 18 and older with hepatitis B Design: Participants will be screened twice with a medical history, physical exam, and blood and urine tests. Participants will be randomly put in one of two groups. All participants will get peginterferon for 24 weeks. One group will first get HBIg for 12 weeks. Participants in the combination group will have a 4-day clinic stay. They will have: Repeats of screening tests Eye exam Liver ultrasound The first dose of HBIg by IV over 2 hours These participants will get HBIg at the clinic up to 8 times over 12 weeks then start the peginterferon. All participants will get peginterferon for 24 weeks. They will get it by injection under the skin once a week. They may do this themselves. They will keep a drug diary. They will have 5 visits to assess response and monitoring for safety.. After stopping the study drug, participants will have 4 follow-up visits over 36 weeks. They will repeat screening tests and have 1 liver ultrasound.
Vaccine-preventable diseases such as hepatitis A and meningitis, as well as cancers caused by human papillomavirus (HPV) disproportionately impact young Black men who have sex with men (YBMSM). Traditional techniques of vaccination promotion have been unable to address the racial disparities in vaccination rates. One promising method for influencing behavior change within YBMSM networks is diffusion of information through Popular Opinion Leaders (POLs). The POL model engages persons who are leaders within their own networks/communities to promote behavior change. The objective of this project is to develop and pilot test a POL intervention to increase routine HAV, HPV and meningococcal conjugate vaccination among YBMSM, ages 18-26. research (PAR) framework to facilitate community support and ensure intervention strategies are salient. PAR includes community members as equal collaborators in the research process. Outcomes from these aims are expected to have an impact on health outcomes by identifying effective strategies for increasing vaccination and routine healthcare engagement among YBMSM.
Primary Efficacy Objective -To assess whether a 12-week treatment course with oral 50 mg elbasvir plus 100 mg grazoprevir given in a single daily dose to treatment-naïve patients with end-stage renal disease (ESRD) and infected with genotype 4 (GT4) chronic HCV (CHC) infection can produce a sustained viral response (SVR), i.e. HCV RNA below the lower limit of quantification [LLOQ] for 12 weeks (SVR12) after completion of the study treatment course Secondary Objectives - To assess the efficacy of elbasvir/grazoprevir in suppressing HCV viremia in treatment-naïve GT4 CHC patients at each scheduled visit and clinically meaningful endpoints (Week 2, 8 and 12 [End of Treatment - EOT]) and 24 (SVR12) - To assess the safety and tolerability of a 12-week treatment course with elbasvir/grazoprevir in treatment-naïve patients with ESRD and infected with GT4 CHC. - To assess liver fibrosis by non-invasive evaluation of liver stiffness (Fibroscan®) in the same patients before treatment and EOT and SVR12 Clinical hypotheses. Primary Efficacy Hypothesis - A 12-week treatment course with elbasvir/grazoprevir in treatment-naïve patients with ESRD and infected with GT4 CHC infection will result in an HCV RNA below the LLOQ in 95% of patients within 2 weeks of treatment, and at least 95% will have an SVR12. Secondary hypotheses - A 12-week treatment course with elbasvir/grazoprevir in ESRD GT4 treatment-naïve patients will result in undetectable viremia in 95% patients at Week 2, 4, 8 and 12 (EOT) and 24 (SVR12) - Treatment will be safe and well-tolerated in these patients, as determined by the type and number of adverse events identified through laboratory testing, vital signs and physical examinations. - In these patients with liver fibrosis before treatment, the liver fibrosis as assessed by non-invasive evaluation of liver stiffness (Fibroscan®) will improve by EOT and SVR12
The primary objective of the study is to determine the number of adverse events (AEs) reported by chronic hepatitis C (CHC) patients receiving at least 1 dose of daclatasvir (DCV) and asunaprevir (ASV) at the 2 sentinel sites and that have been reported through the Mexican Health Authority's AE surveillance system during a specified 24-month study period. The secondary objective is to describe AEs reported by CHC patients receiving treatment with DCV and ASV treated by doctors at participating sentinel sites for the National Pharmacovigilance Center (CNFV) in Mexico during a specified 24-month study period.
This study will evaluate the persistence, immunogenicity and safety of Havrix® (hepatitis A vaccine) in adults primed in infancy. The enrolled subjects will be assessed for circulating antibodies against hepatitis A and will also receive a challenge dose of Havrix Adult vaccine. In the present study, the anamnestic response will be assessed 30 days after the challenge dose.
Hepatitis C is an important health problem in Myanmar affecting around 3% of the population. New drugs have been developed which have transformed the treatment of this disease around the world with very high success rates. Two of these drugs are now registered for use in Myanmar. In this study 200 patients with chronic hepatitis C(100 with HIV co-infection) will be assessed and started on the new treatment. We will observe them and measure treatment effectiveness and tolerability. In 24 patients extra blood samples will be taken for drug measurements to describe the effect of the drugs on patients in Myanmar in more detail.
This is a non-randomized, open-label study of a fixed dose combination (FDC) of elbasvir (50 mg) and grazoprevir (100 mg) (EBR/GZR or MK-5172A) in participants with chronic hepatitis C virus (HCV) genotype 1 (GT1) infection with advanced fibrosis with and without human immunodeficiency virus (HIV) co-infection. All participants will be either HCV treatment naïve (TN) or treatment experienced (TE).
This is a Phase 2a, multi-center, randomized, double-blind, placebo-controlled study evaluating the safety, efficacy, and pharmacokinetics (PK) of AL-3778 in combination with Peg-IFN in subjects with Hepatitis B e antigen (HBeAg) positive CHB virus infection who are treatment-naïve. The study will consist of a screening phase , a double-blind treatment phase followed by treatment with Peg-IFN alone, and a post-treatment follow-up phase. Approximately 30 subjects to complete the study. Eligible subjects will be randomized into 2 treatment arms in a 2:1 ratio (active:placebo) to receive one of the following treatments: - Arm A: Peg-IFN plus AL-3778 (N=20) - Arm B: Peg-IFN plus matching placebo (N=10)
