NCT ID: NCT01265511 Completed - Clinical trials for Hepatitis C Infection

Study of SCY-635, Pegasys and Copegus in Hepatitis C

Start date: November 2010
Phase: Phase 2
Study type: Interventional

This study will examine the effectiveness of 28 days of triple combination therapy including SCY-635 with peginterferon alfa 2a and ribavirin in reducing serum HCV RNA levels. An additional 20 weeks of treatment with the currently approved standard of care will be offered to all participants. The Week 24 visit will be the last on-study visit. After the Week 24 visit, all subjects with undetectable HCV RNA will be given the option to continue treatment with standard of care for an additional 24 weeks (out to Week 48) under the care of their Principal Investigator.

NCT ID: NCT01185028 Completed - HIV Infection Clinical Trials

A Safety and Tolerability Study of Nitazoxanide in HIV-HCV Treatment Failures

Start date: August 2010
Phase: Phase 1/Phase 2
Study type: Interventional

Background: - Chronic hepatitis C (CHC) is a major health problem that particularly affects individuals with human immunodeficiency virus (HIV) infection, and can lead to cirrhosis and liver failure. Standard treatment for people with HIV and CHC is a 48-week course of pegylated-interferon alfa 2a (peg-IFN) and ribavirin (RBV), but better treatments are needed for those who either do not respond to the drugs or who relapse after treatment. - Nitazoxanide has been approved by the Food and Drug Administration primarily to treat diarrhea caused by parasites, and it has been studied in the treatment of CHC infection. However, it has not been tested in persons infected with HIV and CHC co-infection. Researchers are interested in determining whether nitazoxanide is a safe and tolerable treatment for CHC in individuals with HIV. Objectives: - To assess the safety and tolerability of using nitazoxanide to treat chronic hepatitis C infection in individuals with HIV who have not responded to standard treatment for hepatitis C. Eligibility: - Individuals at least 18 years of age who have been diagnosed with both HIV and chronic hepatitis C, and who have either not responded to or relapsed after previous hepatitis C treatment. Design: - Participants will be screened with a physical examination and medical history; blood and urine tests; imaging studies; possible heart, lung, and psychological tests; and a liver biopsy if one has not been done in the past 3 years. - Participants will receive nitazoxanide, the medication being studied, to take by mouth for 4 weeks, and will provide blood samples during this time. - After 4 weeks, participants will receive the first dose of peg-IFN and RBV. Participants will have weekly injections of peg-IFN and continue to take nitazoxanide and RBV by mouth for 48 weeks. Individuals who are slow to respond to this combined CHC treatment (nitazoxanide, peg-IFN, and RBV) by week 12 will continue to have the combined treatment for an extended period, a total of 72 weeks. - Participants will have study visits to provide blood samples and have other tests two times in the first month of combined treatment, and then at months 2, 3, 4, 7, 10, 13, 19; and month 25 only in participants slow to respond to combined treatment. - Some participants who are on specific HIV treatment regimens may enroll in a substudy that will require three separate 12-hour visits for repeated blood samples and other tests during the initial 4-week nitazoxanide treatment.

NCT ID: NCT01051414 Completed - Clinical trials for Hepatitis C Infection

An Anti-viral Combination Study With Japanese Hepatitis C Infection (HCV) Subject

Start date: April 2010
Phase: Phase 2
Study type: Interventional

To assess the efficacy and safety profile of co-administration of BMS-790052 and BMS-650032 for 24 weeks treatment.

NCT ID: NCT01017575 Completed - Clinical trials for Hepatitis C Infection

Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care in Japanese Patients (Pegylated-interferon Alpha-2a and Ribavirin)

Start date: December 2009
Phase: Phase 2
Study type: Interventional

The purpose of this study is to identify at least 1 dose of Daclatasvir, that when combined with peginterferon-alfa (PegIFNα) and ribavirin (RBV) for the treatment of chronically infected HCV genotype 1 treatment-naïve and non-responder to standard of care subjects is safe, well tolerated, and efficacious

NCT ID: NCT01016912 Completed - Clinical trials for Hepatitis C Infection

Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care (Pegylated-interferon Alpha-2b and Ribavirin) in Japanese Patients

Start date: December 2009
Phase: Phase 2
Study type: Interventional

The purpose of this study is to identify at least 1 dose of daclatasvir that is safe, well tolerated, and efficacious when combined with peginterferon-alfa and ribavirin for the treatment of hepatitis C virus genotype 1 in chronically infected patients who are treatment-naïve and nonresponsive to the standard of care

NCT ID: NCT00991289 Completed - HIV Infection Clinical Trials

Nitazoxanide Plus Ribavirin and Peginterferon for Therapy of Treatment Naive HCV Genotype 1 and HIV Coinfected Subjects

Start date: January 2010
Phase: Phase 2
Study type: Interventional

Infection with hepatitis C virus (HCV) can cause liver scarring, or cirrhosis, and this usually occurs more rapidly among people infected with both HCV and human immunodeficiency virus (HIV). People infected with both HCV and HIV have poor response to the current HCV treatments. This phase II pilot study evaluated whether adding a new HCV medication improves response to the current standard HCV treatment with pegylated interferon and ribavirin in people with both HCV and HIV.

NCT ID: NCT00874770 Completed - Clinical trials for Hepatitis C Infection

Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care (Pegylated-interferon Alpha and Ribavirin)

Start date: June 2009
Phase: Phase 2
Study type: Interventional

The purpose of this study is to identify 1 or more doses of daclatasvir, which when used in combination with pegylated interferon alpha and ribavirin, are safe and demonstrate sufficient anti-hepatitis C virus activity.

NCT ID: NCT00841477 Completed - HIV Infection Clinical Trials

An Hepatitis B Vaccine Model for HIV Vaccine Trials in Drug Users

Start date: January 2004
Phase: Phase 3
Study type: Interventional

The goal of the proposed study is to use the HBV vaccine as a model for a future HIV vaccine trial, examining the efficacy of community-based outreach intervention as well as an accelerated vaccine schedule as a method for increasing acceptance/adherence with HBV vaccination protocols among not-in-treatment drug users. This study will also examine the effect of HBV vaccination coupled with community-based outreach intervention on reducing the incidence of HIV, HBV and HCV infections and the frequency of needle use and sexual risk behaviors related to these viral transmissions. A secondary purpose will be to assess the antibody response after HBV vaccination as a measurement of immunological response in drug users.

NCT ID: NCT00513461 Completed - Clinical trials for Hepatitis C Infection

Liver Cancer Prevention Trial in Patients With Chronic Hep C Infection

Start date: October 2007
Phase: Phase 2
Study type: Interventional

This randomized phase II trial studies how well S-Adenosyl-L-Methionine Disulphate P-Toluene-Sulfonate (SAMe) works compared to a placebo in preventing liver cancer in patients with chronic hepatitis C infection. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of SAMe may keep cancer from forming in patients with advanced liver disease
