Filter by:This is a 2 part study of the safety, pharmacokinetics and pharmacodynamics of MK-6325 in HCV-infected participants. Part I of the study will be for Genotype (GT) 1 HCV-infected participants who will be randomized to receive either MK-6325 or placebo. If the drug is shown to be safe and efficacious in Part I, Part II will enroll GT 3 HCV-infected participants who will be randomized to receive either MK-6325 or placebo.
To describe liver enzyme elevations in patients who are coinfected with HIV and either Hepatitis C (HCV) and/or Hepatitis B (HBV) receiving maraviroc or placebo in combination with their current suppressive anti-HIV drug therapy.
The purpose is to evaluate efficacy and safety of therapeutic hepatitis B virus (HBV) vaccine (mimogen-based)) Joint entecavir treatment in chronic hepatitis B patients.
The primary aim of this study is to asses the efficacy (both virological and clinical) and safety of ETV in both NA-naïve and NA-experienced chronic hepatitis B patients, and to explore baseline factors associated with virologic reponse (VR) to ETV.
The purpose of this study is to investigate the efficacy of a treatment with TMC435 in combination with peginterferon alfa-2a and ribavirin in patients who did not clear their hepatitis C infection with peginterferon alfa-2a and ribavirin alone within a previous trial conducted by Tibotec, or who participated in Tibotec trials in which antivirals directed against hepatitis C virus (HCV) were evaluated for short periods of time.
This study will assess the safety and efficacy of Alisporivir when added to pegIFN and Ribavirin to optimize treatment in patient infected with the Hepatitis C virus who have not been previously treated for this condition
The relevance of this research to public health is to make it possible to test for hepatitis C and syphilis at point of care so that people will receive their results immediately instead of requiring people to wait for at least a week to get their test results. This research will make rapid tests for HIV available that can detect HIV infection earlier and are more accurate than current tests available in the United States.
A Double-Blind, Randomized, Placebo-Controlled, Multiple Dose Ranging Study Evaluating the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of GS-6620 in Treatment Naïve Subjects with Chronic Hepatitis C Virus Infection.
The purpose of this study was to assess the safety, pharmacokinetics, and 4-week rapid virologic response (RVR) of 3 different doses of ABT-267 (also known as ombitasvir) in combination with pegylated interferon/ribavirin (pegIFN/RBV) compared with pegIFN/RBV alone (ABT-267 placebo) in treatment naïve, hepatitis C virus (HCV), genotype 1-infected participants.
In order to clarify the association between HBV mutations appearing before and during interferon therapy and the therapeutic effects, serial serum samples from 100 HBeAg-positive CHB patients undergoing peginterferon alfa-2a therapy will be collected and analyzed for the mutations of preS/S gene and BCP-preC/C region, particularly for the deletion mutations. Furthermore, Real-Time PCR will be performed to measure the ratios of wild-type HBV and deletion mutant HBV before and at the end of peginterferon alfa-2a therapy. Finally, statistical analysis will be done to elucidate whether the mutations of preS/S gene and BCP-preC/C region have any relation with the therapeutic effect of peginterferon alfa-2a.
