Active clinical trials for "Hepatitis C"

The purpose of this study is to determine whether pegylated interferon therapy is effective to treat acute hepatitis C infection in HIV-coinfected individuals.

Chronic hepatitis C is a disease of the liver caused by the hepatitis C virus. The disease can be serious and even fatal. Approximately 25% of patients with chronic hepatitis C will develop cirrhosis and some of these patients will develop cancer of the liver or liver failure. Presently the disease is treated with a combination of alpha interferon or peginterferon (antiviral and immune stimulating drugs) and ribavirin (an antiviral drug). Alpha interferon is given by injection three times a week whereas peginterferon is given by injection only once a week. Ribavirin is given as a tablet by mouth twice a day. The combination therapy is given for 6 to months. About half of the patients given these medications will receive a lasting benefit and many patients do not respond well to the combination therapy. This study will select up to 50 patients will chronic hepatitis C who have not responded to combination therapy or who could not stand the side effects associated with interferon or peginterferon therapy. These subjects will be evaluated and undergo liver biopsy to determine their present liver condition. If selected as subjects they will be started on single drug therapy with ribavirin. The drug will be given orally twice a day at a dose based on the patient's body weight. The patients will be followed on an out-patient basis. They will we asked to return for regular check-ups and blood tests every 2 to 8 weeks for the duration of the study. After 6 months, the medication will be stopped or adjusted based on the results of the subject's blood tests (liver enzymes). A response is considered if a decrease of 50% or more of the initial liver enzyme (alanine aminotransferase, ALT) is noted. A complete response will be considered if liver enzymes return to normal levels. Therapy will be discontinued after 6 months if patients do not respond. However, patients that respond to the single drug therapy will continue to receive the medication at a decreased dose. The patients will remain on an appropriate dose for up to 8 years with repeat liver biopsies at 2, 4 and 8 years to assess progress. This study will determine if long-term therapy with ribavirin is safe and effective.

Hepatitis C is a major cause of liver disease in the United States and leads to cirrhosis of the liver in approximately one-third of patients some of whom will ultimately suffer from liver failure or liver cancer. At present, the recommended therapy of hepatitis C is the combination of alpha interferon and ribavirin given for 6 to 12 months. Ribavirin is a antiviral drug that is given by mouth. Interferon is both an antiviral and an immune medication which must be given by injections (three times a week) and has many difficult side effects. The purpose of this study is to determine whether the combination of ribavirin and interferon improve the liver disease of hepatitis C and whether improvements can be maintained by continuing ribavirin therapy long-term. This study will take 100 to 120 patients suffering from hepatitis C and place them under combination drug therapy with alpha interferon and ribavirin. The course of drug therapy is scheduled to last 6 to 12 months. Patients will be selected after appropriate screening for hepatitis C virus and elevated liver enzymes are conducted and liver biopsy shows chronic hepatitis with some degree of injury and scarring. During the first 6 months of the study, subjects will be asked to return to the outpatient clinic for routine check-ups and blood tests every 2 to 4 weeks. Blood tests will include tests for hepatitis C virus. If the virus test becomes negative on treatment, the therapy will be considered successful and will be continued for a full 6 or 12 months (depending upon the strain of virus). If the virus test does not become negative during the first six months of treatment, subjects will be considered "non-responders" and will stop taking interferon but will continue on ribavirin alone or an identically appearing placebo tablet. These non-responsive subjects will continue this therapy for an additional 12 months. (A year-and-a-half total). Upon completion of the drug therapies, subjects will be requested to submit blood samples and undergo a liver biopsy to determine if the therapy was successful. Test results that reveal a loss of hepatitis C antibodies or normal levels of liver enzymes will be deemed successful. Patients that have successful laboratory test results will be considered for continuation of ribavirin therapy. Patients that received placebo for a year will be eligible to receive ribavirin long-term at the end of the study.

This study will examine the effectiveness of pegylated interferon, or peginterferon (a long-acting form of alpha interferon) plus ribavirin in treating hepatitis C (genotype 1) infection with and without kidney disease.

This study aims to assess the efficacy and safety of sofosbuvir (SOF) with pegylated interferon (PegINF)/ribavirin (RBV) for chronic HCV GT4 participants

The objective of the investigators was to delineate the efficacy and safety of Ombitasvir, paritaprevir with ritonavir (OBV/PTV/r) plus ribavirin (RBV) on chronic HCV GT4 Egyptian naïve patients

In this study, individuals without hepatitis C infection who are on the kidney transplant waitlist will receive a kidney from a deceased donor with hepatitis C infection and will be treated for hepatitis C at the same time. Treatment will include glecaprevir 300 mg / pibrentasvir 120 mg (G-P) administered on-call to the operating room for the renal transplant procedure and continued for 4 weeks post-renal transplant.

Recently the era of direct-acting antiviral drugs for hepatitis C treatment has changed the world map of HCV. Results in adults are promising. FDA approved only two drugs in the pediatric age group 12 to 17 years. Younger children are still on the wait list for treatment. The current study aimed to treat children aged between 3 and 12 years with half the adult dose of Sofosbuvir/Ledipasvir combination (Heterosofir).
