Active clinical trials for "Hepatitis"

This study intends to investigate whether addition of PEG-IFN alfa-2a in HBeAg-negative chronic hepatitis B patients who are pretreated with nucleos(t)ide analogues enhances the degree of HBsAg decline.

The purpose of this study is to assess the safety and antiviral activity of IDX184 in combination with pegylated interferon and ribavirin in treatment-naïve subjects with genotype 1 chronic hepatitis C virus (HCV) infection.

The purpose of this study is to determine if combination therapy with Pegylated Interferon Lambda (BMS-914143) plus Ribavirin (RBV) with a single direct antiviral agent (BMS-790052 or BMS-650032) for 24 weeks is effective and safe for treatment of Chronic Hepatitis C (CHC) compared to current standard therapy with Pegylated Interferon Alpha-2a plus RBV for 48 weeks.

This study will examine the effectiveness of 15 days of therapy with SCY-635 in reducing hepatitis C virus (HCV) RNA levels.

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.

The purpose of this study is to study the effects of valacyclovir on patients who have hepatitis C and antibodies to herpes simplex type-2. Herpes simplex type 2 is a virus which causes genital herpes. Some persons with genital herpes have sores in their private areas but most persons do not have any symptoms at all. Valacyclovir is a medication which is commonly used to treat or prevent outbreaks of genital herpes. This medication is already approved by the Food and Drug Administration to treat genital herpes. Valacyclovir has not been approved to treat chronic hepatitis C. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and the persons participating will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 3-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center.

The purpose of this phase 2 study is to determine whether 30 mg or 90 mg of GS-5885 when given with GS-9451, Tegobuvir and Ribavirin (RBV) for 12 or 24 weeks is effective, safe and tolerable in the treatment of Chronic Genotype 1 HCV Infection.

This equally randomized (1:1), double-blind, parallel arm study will assess the safety and antiviral efficacy of RO5024048 added to standard Pegasys (peginterferon alfa-2a) plus Copegus (ribavirin) therapy in patients with chronic hepatitis C genotype 1 or 4. Patients in arm A will receive RO5024048 (1000mg orally twice daily) for 24 weeks in addition to Pegasys (180 micrograms sc weekly) and Copegus (1000mg or 1200mg orally daily). Patients achieving a rapid virological response (RVR) at week 4, sustained through week 22, will stop all treatment at week 24; non-RVR patients will continue treatment with Pegasys and Copegus for another 24 weeks up to week 48. Patients in arm B will receive standard treatment with Pegasys (180 micrograms sc weekly) and Copegus (1000mg or 1200mg orally daily) for 48 weeks. Anticipated time on study treatment is up to 48 weeks. Target sample size is <200.

This open-label, multi-center study will evaluate the effect on the quantitative HBsAg reduction of peginterferon alfa-2a [PEGASYS] in patients with HBeAg positive chronic hepatitis B. Patients will receive PEGASYS 180 mcg sc once weekly. After 24 weeks of treatment, rapid responders will receive another 24 weeks of treatment. After 24 weeks of treatment, slow responders will be randomized to another 24 or 72 weeks of PEGASYS monotherapy, or to 72 weeks PEGASYS plus 36 weeks adefovir (10 mg, po once daily, starting from week 29 of PEGASYS treatment). The anticipated time on study drug is >2 years.

This study is a multi-center, randomized, open-label and positive controlled Phase II Clinical trial to assess the efficacy and safety of Ypeginterferon alfa-2b (with Ribavirin), once a week, in 3 dose-groups respectively, for treatment of Chronic Hepatitis C patients, with Pegasys 180mcg/week & Ribavirin as positive control. It is aimed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase III trials, and generate the PK data in hepatitis C patients to satisfy regulatory requirements.
