NCT ID: NCT00635804 Completed - Hepatitis C Clinical Trials

Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of MK-3281 in Healthy and Hepatitis C Infected Male Participants (MK-3281-002)

Start date: February 19, 2008
Phase: Phase 1
Study type: Interventional

This study will examine the safety, tolerability and plasma pharmacokinetics of multiple doses of MK-3281 in healthy male participants in Part I, and in Hepatitis C Virus (HCV)-infected male participants in Part II. The clinical efficacy of MK-3281, as measured by viral load reduction, will also be assessed in Part II. The primary hypothesis is that twice daily administration of MK-3281 for 10 days in healthy adult male participants and for 7 days in HCV-infected male participants is sufficiently safe and well tolerated, based on assessment of clinical and laboratory adverse experiences, to permit continued clinical investigation. The results of this study will guide dose selection for future studies in both healthy participants and HCV-infected participants.

NCT ID: NCT00633243 Completed - Hepatitis C Clinical Trials

Effective Treatment of Hepatitis C in Substance Users

Start date: April 2007
Phase: N/A
Study type: Interventional

We hypothesize that integrating Hepatitis C into methadone and buprenorphine treatment will improve Hepatitis C outcomes as well as drug treatment outcomes in patients who are addicted to opiates. We will test this hypothesis by randomly assigning patients to receive integrated or separated care. The first group will receive Hepatitis C treatment and substance abuse treatment contemporaneously at the South Central Rehabilitation Center (SCRC). They will take both methadone or buprenorphine and Hepatitis C medications under the daily (methadone) or weekly (buprenorphine) observation of a health care provider. The second group will receive substance abuse treatment at SCRC, and go to another facility to receive Hepatitis C treatment services. These participants will take their medications on their own (without observation). We will look at outcomes such as Hepatitis C viral loads, adherence to medications, and drug treatment outcomes such as receipt of buprenorphine and methadone and urine toxicology testing.

NCT ID: NCT00630084 Completed - Neoplasms Clinical Trials

Peginterferon Plus Ribavirin for Hepatitis C Patients Concomitant With Malignancy Other Than Hepatocellular Carcinoma

Start date: August 2006
Phase: Phase 4
Study type: Interventional

Combination therapy with pegylated interferon-alpha plus ribavirin has greatly improved the treatment efficacy and is the mainstream of treatment for chronic hepatitis C infection. The efficacy and safety of pegylated interferon-alpha plus ribavirin combination therapy and its impact on the outcome in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma deserve to be elucidated. The purposes of this study are: 1. To evaluate the efficacy and safety of pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma, compare to those without systemic malignancy. 2. To investigate the role of baseline and on-treatment factors on the response to pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma.

NCT ID: NCT00630058 Completed - Hepatitis C Clinical Trials

A Phase 1 Study of MP-424, Peginterferon Alfa 2b, and Ribavirin in Hepatitis C

Start date: April 2008
Phase: Phase 1
Study type: Interventional

The purpose of this study is to assess the safety, pharmacokinetics, HCV RNA kinetics, and other viral characteristics after administration of two arms of MP-424 in combination with Peginterferon Alfa 2b (PEG-IFN-a-2b) and Ribavirin (RBV) to patients with chronic hepatitis C.

NCT ID: NCT00629967 Completed - Chronic Hepatitis C Clinical Trials

A Randomized Trial of 24-Week Versus 48-Week Courses of Peginterferon Plus Ribavirin for HCV Genotype-1 Patients

Start date: April 2005
Phase: Phase 4
Study type: Interventional

The purposes of this study are: 1. To evaluate whether treatment with peginterferon and ribavirin for 24 weeks is sufficient to achieve a sustained virological response (SVR) rate comparable to that observed with the standard treatment duration of 48 weeks, in hepatitis C virus genotype 1 (HCV-1) patients achieving a rapid virologic response (RVR; <50 IU/mL HCV RNA at week 4) at 4 weeks. 2. To investigate the role of on-treatment virological responses among patients with 24 or 48 weeks treatment.

NCT ID: NCT00629824 Completed - Chronic Hepatitis C Clinical Trials

Pegylated Interferon Plus Ribavirin in Treating Older Patients With Chronic Hepatitis C

Start date: February 2007
Phase: Phase 4
Study type: Interventional

Combination therapy with pegylated interferon-alpha plus ribavirin has greatly improved the treatment efficacy and is the mainstream of treatment for chronic hepatitis C infection. The efficacy and safety of pegylated interferon-alpha plus ribavirin combination therapy and its impact on the outcome in older patients with chronic hepatitis C deserve to be elucidated. The purposes of this study are: 1. To evaluate the efficacy of pegylated interferon-alpha 2a plus ribavirin combination therapy in older patients with chronic hepatitis C 2. To investigate the safety of pegylated interferon-alpha 2a plus ribavirin combination therapy in older patients with chronic hepatitis C

NCT ID: NCT00627926 Completed - Hepatitis C Clinical Trials

A Phase 3 Study of Telaprevir in Combination With Pegasys® and Copegus® in Treatment-Naive Subjects With Genotype 1 Hepatitis C Virus (HCV)

Start date: March 2008
Phase: Phase 3
Study type: Interventional

A Phase 3 study to evaluate the efficacy and safety of two dosing regimens of telaprevir in combination with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV).

NCT ID: NCT00624325 Completed - Chronic Hepatitis C Clinical Trials

Subcutaneous Continuous Infusion of Interferon Alfa-2b and Ribavirin in Hepatitis C Genotype 1 Nonresponders

SCIN-C
Start date: July 2007
Phase: Phase 2/Phase 3
Study type: Interventional

For chronic hepatitis C patients unresponsive to previous (PEG-)IFN/RBV combination therapy we propose continuous subcutaneous administration of high-dose IFN-a2b (Intron A®) for 48 weeks in combination with 15 mg/kg/day RBV (Rebetol®) and optimal management of side effects in order to maintain the highest possible dosages of both IFN-a2b and RBV for 48 weeks. We expect improved tolerability with continuous subcutaneous pump delivery of IFN-a2b compared to thrice weekly or daily subcutaneous injection of IFN-a2b, and increased antiviral activity and biologic potency due to sustained and higher levels of a fully potent interferon protein.

NCT ID: NCT00623428 Completed - Clinical trials for Hepatitis C, Chronic

A Study of Combination Therapy With PEGASYS (Pegylated Interferon Alfa-2a (40KD)) and Copegus (Ribavirin) in Patients With Chronic Hepatitis C Genotype 2 or 3 Who Do Not Achieve a Rapid Viral Response

Start date: June 2008
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy and safety of peginterferon alfa-2a 40KD + ribavirin combination therapy given for 24 weeks versus 48 weeks in patients with chronic hepatitis C, genotype 2/3.
