Phase 1, randomized, double-blind, placebo-controlled, dose-escalation study with 3 dose levels of IMO-2125 in combination with standard weight based ribavirin (investigational treatment arm) or placebo in combination with ribavirin (RBV). Each cohort of 15 patients will be randomized 4:1 to receive the investigational treatment arm (12 patients) or placebo and RBV arm (3 patients).
This is a phase 1, randomized, double-blind, placebo-controlled, dose-escalation study with 3 dose levels of IMO-2125 in combination with standard ribavirin or placebo plus ribavirin. Each cohort will be randomized 4:1 to receive the investigational treatment arm or placebo and ribavirin. Three varying dose levels of IMO-2125 will be included. In both arms, ribavirin will be dosed based on patient weight.
Approximately 50 patients will be enrolled in France and Russia. Patients will provide informed consent prior to any screening procedures being performed. Screening will occur within 21 days prior to randomization. Enrolled patients who qualify and proceed successfully through the screening period will be randomized to receive 4 weeks of either the investigational treatment arm (IMO-2125 and ribavirin) or placebo and ribavirin, with a 4 week follow-up period.
Patients who are randomized to the investigational treatment arm will receive one of 3 dose levels of IMO 2125 SC once weekly; each patient will receive the same dose throughout the 4 weeks of treatment. In addition to IMO-2125 treatment they will also receive daily ribavirin, which will be given based on the patients weight and will be taken twice daily for a total of 4 weeks.

First-in-humans, phase 1, dose-escalation study with 4 dose levels of single-agent IMO-2125.
The study will be a randomized, double blind, placebo controlled, dose rising study in Interferon alpha (IFN-alpha) non-responder HCV infected patients or HCV patients who have relapsed fo...

This is a multicenter clinical trial designed to compare the efficacy of 48 weeks of therapy with pegylated (PEG)-Interferon/ribavirin in Southeastern Asian patients with genotype 1 chroni...
Genotype 4 is the least-studied hepatitis C virus genotype and was considered a difficult to treat genotype due to the disappointing response of chronic hepatitis C genotype 4 to conventio...
The incidence of mixed genotype hepatitis C virus infections in the UK is largely unknown. As the efficacy of direct acting antivirals is variable across different genotypes, treatment regimens are ta...
To determine the clinical characteristics of hepatitis B virus (HBV) reactivation in patients undergoing interferon-free anti-hepatitis C virus (HCV) therapy, we examined HBV DNA in 25 HBV co-infected...
Direct-acting antivirals (DAAs) are the first-line treatment for patients with chronic hepatitis C virus (HCV) infection. However, its effects on patients with acute HCV infection are poorly understoo...
Hepatitis B virus (HBV) from 76 adult immigrants in Australia from Myanmar was characterised to determine the prevalence of different HBV genotypes and subgenotypes. A mutational analysis was then per...
We aimed to evaluate the safety and effectiveness of 12 or 24 weeks treatment with ledipasvir and sofosbuvir, with or without ribavirin, in treatment-experienced patients with hepatitis C virus (HCV) ...
Oral HCV-PROTEASE INHIBITOR effective against hepatitis C virus (HCV) serine protease NS3/4A. It is used in the treatment of chronic hepatitis C (Antivirals) genotype 1 infection in adults with compensated liver disease, including CIRRHOSIS.
INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis B and chronic hepatitis. It requires the presence of a hepadnavirus for full replication. This is the lone species in the genus Deltavirus.
INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).
A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
