  Purpose

Researchers want to see whether Sho-saiko-to (SST) can help in patients with chronic hepatitis C. Chronic hepatitis C may cause swelling within the liver and this can lead to scar tissue. In some patients, severe scarring of the liver, liver failure and liver cancer can occur. Standard treatment for chronic hepatitis C is a drug called interferon with or without another drug called ribavirin. There are a number of side effects that some patients are unable to take. Other patients may have an initial response, but then the virus and the inflammation come back.

Sho-saiko-to is an herbal medicine that has been used for many years in Asia to treat liver disease. The purpose of the study is to evaluate whether Sho-saiko-to may improve liver swelling and injury caused by chronic hepatitis C.

Primary Outcome Measures:
  • To determine the effects of Sho-saiko-to on hepatic injury in patients with chronic hepatitis C who are intolerant or have a specific contraindication to interferon-based therapy. [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine the effects of SST therapy on liver function and viral load [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]

Enrollment: 41

Study Completion Date: February 2011

Arms Assigned Interventions
Experimental: 1
All patients will receive treatment with 2.5grams of SST as granules in packet form by mouth three times a day every day for 52 weeks unless occurrence of unacceptable adverse events or patient withdrawal.
Other: Sho-saiko-to
All patients will receive treatment with 2.5grams of SST as granules in packet form by mouth three times a day every day for 52 weeks unless occurrence of unacceptable adverse events or patient withdrawal. Patients will be seen for clinical follow-up at three month intervals: at 3, 6, 9, and 12 months, and assessed for compliance and asked about side effects and pulmonary symptoms. At each clinic visit, a comprehensive metabolic profile will be performed. At the 6-month clinic visit, a CBC will be performed. At the 12-month clinic visit, quantitative HCV-RNA by PCR will be obtained (Viromed Labs, Inc., 6101 Blue Circle Drive, Minneapolis, MN 5534). Within 4 weeks after the 12-month clinic visit (after 52 weeks of SST therapy), the second liver biopsy will be scheduled and performed.

Detailed Description:

Chronic hepatitis C affects nearly three million Americans. Of these, 15% will develop liver cirrhosis and approximately 5% will progress to hepatocellular carcinoma. Treatment for chronic hepatitis C is limited to interferon-based therapy. Many patients decline or cannot tolerate interferon because of its serious side effects. Sho-saiko-to, an Asian herbal medicine consisting of seven botanicals, has demonstrated anti-fibrotic affect by inhibition of lipid peroxidation in hepatocytes and stellate cells in an animal study. It has also been demonstrated to prevent progression of cirrhosis to hepatocellular carcinoma in human trials. This study is a single arm, single center trial of Sho-saiko-to in patients with chronic active hepatitis from hepatitis C infection who cannot tolerate or who have specific contraindications to interferon therapy. Patients will receive 52 weeks therapy with Sho-saiko-to. Outcome will be assessed by comparing pre- and posttreatment liver biopsies. Patients will be said to respond if they have an improvement of two points or greater on a standard measure of liver histology. If five or more of 25 evaluable patients respond, Sho-saiko-to will be deemed worthy of further testing.

  • Age 18 or over
  • There must be no plans to use interferon in the following 12 months due to EITHER: a specific contraindication to interferon therapy, including but not limited to:history of depression, or other psychiatric disease, history of autoimmune disease,psoriasis, rheumatoid arthritis, history of renal dysfunction, thyroid abnormalities, seizure disorder, depressed blood cell counts, history of asthma OR patient discontinuation of interferon-based therapy prematurely due to intolerable side effects with sustained active viremia OR patient refusal to take interferon
  • Patients must be able to understand and sign informed consent.
