Filter by:The purpose of this study is to describe current rescue treatment pattern for nucleot(s)ide analogue (NA) resistance and assess the real-world treatment outcomes and health resources utilization of rescue treatments for drug resistance in a clinical cohort of Chinese patients with chronic hepatitis B (CHB).
This is an expanded access, multicenter, national, open-label, and non-randomized study to analyze the safety of peginterferon alfa-2a in participants with hepatitis B e antigen (HBeAg) positive and HBeAg negative chronic HBV. All participants will receive 48 weeks treatment of peginterferon alfa-2a monotherapy, followed by a 24 week treatment-free follow-up period. Total length of the study is anticipated to be approximately 72 weeks.
This multicenter, open-label, uncontrolled study will evaluate the efficacy and safety of increasing the dose of peginterferon alfa-2a (Pegasys) in participants with Genotype 1/4/5/6 CHC and an early non-response to a standard course of peginterferon alfa-2a plus ribavirin. The study will consist of screening (4 weeks), treatment (32 weeks), and follow-up (24 weeks).
Introduction: Vitamin D binding protein (VDBP) is a potential modulator of immune response and is associated with clinical progression of many diseases. Our aim is to assess influence of baseline 25-hydroxyvitamin D levels and VDBP single nucleotide polymorphisms (SNPs), rs4588 (C>A) and rs7041 (G>T), on baseline clinical parameters and response to interferon based therapy in chronic Hepatitis C patients in Egypt. Methodology: Genotyping will be performed by RFLP (Restriction Fragment Length Polymorphism) in treatment naïve Hepatitis C patients and healthy controls. Vitamin D levels will be assessed by ELISA. HCV RNA quantification will be performed by PCR to assess therapy outcome.
Ultrasound (US) B mode image is an alternative method to measure tissue structure and has proven to be an accurate technique to measure subcutaneous fat thickness. However, pressing the transducer onto the skin with too much force will significantly reduce the subcutaneous adipose tissue thickness. In this study, a force controlled system combined with US transducer was used for 3D subcutaneous fat imaging and reconstruction.
This study will collect and evaluate information on the safety and efficacy of Sovaldi-based regimens in routine clinical practice in Mexico. The primary objective of this study is to assess the rates of serious adverse events/reactions (SAEs/SADRs) and adverse events/reactions (AEs/ADRs) in adult participants with chronic hepatitis C virus (HCV) infection treated with Sovaldi in routine clinical practice.
Chronic Hepatitis B is the most common cause of chronic viral liver disease worldwide afflicting 350 million persons, leading to significant morbidity and mortality due to liver disease and HCC in 20-40% of infected persons. With the advent of nucleoside analogues, this rescued patients with significant risk of disease progression, but in most circumstances, therapy was needed long term as HBsAg seroclearance was an uncommon occurrence, and stopping therapy was associated with relapse of disease and hepatitis B flares. The use of pegylated interferons showed increased HBeAg seroconversion and HBsAg seroclearance rates compared to nucleoside analogues , however combination nucleos(t)ide analogue therapy has been quite disappointing. However a recent showed that the combination of telbivudine and tenofovir in a response guided therapy design, had a remarkable 6% HBsAg seroclearance at week 52 in patients. Such results require further confirmation. There is currently an unmet need for the large number of patients on long term nucleoside analogue therapy who have not achieved HBeAg seroconversion or HBsAg seroclearance. Such patients are seeking alternatives to long term therapy hence an exploration of other therapeutic strategies is attractive. An additional benefit of telbivudine has been the surprising improvement in renal function and this study seeks to examine whether this can improve the renal impairment that may be seen with tenofovir. Our study proposes to examine if the combination of tenofovir and telbivudine can improve endpoints. Patients fulfilling inclusion and exclusion criteria will be randomized to tenofovir or tenofovir and telbivudine (1:1 ratio). The primary endpoint will be a qHBsAg reduction of >1log at week 96, which may predict future HBsAg seroclearance, which is also a secondary endpoint. An additional primary endpoint is increase in eGFR in the combination arm compared to the monotherapy arm. The study aims to enroll 146 patients randomized 1:1 ratio (73:73) patients. Multivariate analysis will be performed of baseline and on-treatment factors that predict the primary outcome.
This phase I trial studies the side effects and best dose of deoxyribonucleic acid (DNA) vaccine therapy in treating patients with hepatitis C virus (HCV) infection that persists or progresses over a long period of time. Vaccines made from DNA may help the body build an effective immune response to kill cancer cells that express HCV infection.
NPC1L1 is a key transporter in the enterohepatic cycle of cholesterol. Initial in vitro and in vivo data show that blocking this receptor with ezetimibe results in delaying infection in these models. The investigators hypothesize that HCV has an enterohepatic cycle, being secreted in bile and reabsorbed either in the canalicular membrane or in the intestine by association with NPC1L1, following a path similar to the cycle of cholesterol in humans. To prove this hypothesis the investigators propose to assess the effect of ezetimibe treatment in HCV infected individuals undergoing liver transplantation to avoid or delay HCV infection. For this purpose, the investigators propose to administrate ezetimibe 10 mg/d for 12 weeks to 12 patients with chronic hepatitis C infection listed for a liver transplantation.
This randomized, multi-center, Phase IV, comparative study will assess the efficacy and safety of combined peg-interferon alpha-2a (Peg-IFN-Alpha-2A) and ribavirin therapy for 48 or 72 weeks of treatment and 24 weeks of follow-up in participants with Genotype 1 chronic hepatitis C (CHC), co-infected with human immunodeficiency virus type 1 (HIV-1).
