Our research staff is composed of an expert staff and departments comprised of experienced Sub Investigators, Research Department Directors, Site Start Up Specialist, Quality Assurance, Contracts and Finance, ACRP certified Coordinators, Patient Recruitment and Pharmacy Technicians. With over 80 skilled healthcare providers and staff we ensure the highest quality of care is delivered to our patients.

 

Simeprevir plus sofosbuvir, with or without ribavirin, to treat chronic infection with hepatitis C virus genotype 1 in non-responders to pegylated interferon and ribavirin and treatment-naive patients: the COSMOS randomised study

Interferon-free regimens are needed to treat hepatitis C virus (HCV) infections. We investigated the efficacy of combined simeprevir and sofosbuvir.

 

Sofosbuvir and ledipasvir fixed-dose combination with and without ribavirin in treatment-naive and previously treated patients with genotype 1 hepatitis C virus infection (LONESTAR): an open-label, randomised, phase 2 trial

Interferon-based treatment is not suitable for many patients with hepatitis C virus (HCV) infection because of contraindications such as psychiatric illness, and a high burden of adverse events. We assessed the efficacy and safety of an interferon-free regimen—a fixed-dose combination of the nucleotide polymerase inhibitor sofosbuvir (400 mg) and the HCV NS5A inhibitor ledipasvir (90 mg), with and without ribavirin—in patients with genotype-1 hepatitis C infection who were treatment-naive or previously treated with a protease-inhibitor regimen.

 

Sofosbuvir with pegylated interferon alfa-2a and ribavirin for treatment-naive patients with hepatitis C genotype-1 infection (ATOMIC): an open-label, randomised, multicentre phase 2 trial

The uridine nucleotide analogue sofosbuvir is a selective inhibitor of hepatitis C virus (HCV) NS5B polymerase. We assessed the safety and efficacy of sofosbuvir in combination with pegylated interferon alfa-2a (peginterferon) and ribavirin in non-cirrhotic treatment-naive, patients with HCV.

Sofosbuvir in combination with peginterferon alfa-2a and ribavirin for non-cirrhotic, treatment-naive patients with genotypes 1, 2, and 3 hepatitis C infection: a randomised, double-blind, phase 2 trial

Protease inhibitors have improved treatment of infection with hepatitis C virus (HCV), but dosing, a low barrier to resistance, drug interactions, and side-effects restrict their use. We assessed the safety and efficacy of sofosbuvir, a uridine nucleotide analogue, in treatment-naive patients with genotype 1—3 HCV infection.

 

An estimated 184 million people worldwide have hepatitis C virus (HCV) infection, a leading cause of chronic liver disease and the leading indication for liver transplantation globally. Approximately 25% of persons with HCV infection in the United States have cirrhosis, and this number is expected…

 Treatment of HCV Infection by Targeting MicroRNA

Approximately 170 million persons worldwide are chronically infected with the hepatitis C virus (HCV). Chronic HCV infection is a major cause of liver cirrhosis, liver failure, and hepatocellular carcinoma and is the leading indication for liver transplantation in many Western countries. Sustained…

As many as 170 million persons are chronically infected with the hepatitis C virus (HCV) worldwide, and more than 350,000 die annually from liver disease caused by HCV. Estimates of the number of persons in the United States who have chronic HCV infection range from 2.7 million to 5.2 million. For…

More than 3 million people in the United States are chronically infected with the hepatitis C virus (HCV). Although the number of new infections has been declining for decades, HCV-related morbidity and mortality are projected to continue rising for another 20 years. One half to three quarters of…

Among the estimated 170 million people in the world who have chronic hepatitis C virus (HCV) infection, approximately 60% have the genotype 1 strain of the virus. The treatment of patients infected with HCV genotype 1 is evolving rapidly.– At the end of 2013, the Food and Drug Administration (FDA)…
