Brief summary: Chronic HCV infection is one of the common causes of the chronic liver disease. Approximately 6-10% of the general public is expected to be suffering from this infection. In case that these patients are not treated at an appropriate time, these patients develop the sequelae of the chronic liver disease e.g. cirrhosis of liver, Ascites, and Hepatocellular carinoma. Interferon alpha 2 a or alpha 2b injections and Ribavirin combination is the treatment of choice for people suffering from Chronic HCV infection and this combination need to be administered for 6-12 months. Interferons are biological agents and are to be administered parenterally. Interferons are expensive and are associated with number of minor and major adverse effects. Ribavirin is also associated with significant adverse effects. These compounds cannot be considered as one of the ideal forms of the treatment.

In the past, quite a few natural products have been tested to assess their hepatoprotective activity and possibly anti viral activity as well. These include Vitamin C (Ascorbic acid), Vitamin E, Zinc, Silymarin, Red beet roots, crushed licorice and etc. etc.

Rationale Iodine , Potassium iodide and Ascorbic acid are natural products used in the management of Thyroiditis and chronic cutaneous fungal infections. This combination of iodine compounds along with ascorbic acid is being used for the management of chronic hepatitis B \& C in the central Asian states e.g. Kazakhstan etc.

The investigators have conducted a feasibility study in which oral Iodine Compound {RENESSANS} was given to patients suffering HCV related Chronic Active Hepatitis and anti-viral activity and safety has been analyzed. In this study, RENESSANS containing regimen has been well tolerated by all the patients and has shown some antiviral activity.

In this study the investigators will assess whether the administration of RENESSANS {oral } improves the antiviral activity in patients receiving standard interferon therapy.

Detailed description: 1. Primary

   The primary objective of this study is to assess the efficacy of combination therapy comprising of RENESSANS, INTERFERONS and RIBAVIRIN in the management of treatment naïve HCV related Chronic Active Hepatitis patients.
2. Secondary

   The secondary objectives of this study are:
   1. Determine the biochemical or virological improvement in patients suffering from HCV related Chronic Active Hepatitis.
   2. Determine the safety and tolerability of Renessans {oral} when administered as a part of antiviral activity outlined in this protocol.
3. ENDPOINTS

   The primary endpoint will be the number of subjects achieving
   1. Virological response as evident by Rapid Viral Response(RVR), Early Viral Response(EVR) and Sustained Viral Response(SVR).
   2. Biochemical response as evident by normalization of ALT.

   The secondary endpoint will be

   a. Assessment of the safety and tolerability of RENESSANS through: routine physical examination, routine clinical laboratory tests, clinical monitoring and adverse events reporting.
4. INVESTIGATIONAL PLAN

   Study Design.

   This is an open labeled, active controlled, three arm, parallel-group study of the safety and efficacy of the oral formulation of natural iodine compound (Renessans) administered alone and in combination with standard interferon therapy in patient suffering from chronic HCV hepatitis.

   The enrolled patients will be tested for following base line laboratory tests

   VISIT 1:

   CBC including platelet count and ESR Liver function tests including albumin and total proteins. Creatinine Serum electrolytes Thyroid Function tests HBsAg, HIV antibody Urinalysis ANA, RA factor and serum ferritin levels USG of abdomen HCV RNA (PCR by amplicor, roche) qualitative analysis, if positive then quantitative analysis (Real time) and genotype as well.

   Pregnancy test in case of females Informed consent shall be obtained and each individual patient's treatment risk shall be covered under a certified health insurance plan.

   Renessans will be administered in eligible patients as follows:

   Study Arm Dosing Schema Group I ORAL RENESSANS 5gm. Thrice Daily{active iodine 300mg} for 6months Group II a ORAL RENESSANS 5gm. Twice Daily +INTERFERON ALPHA 2b 3 Million Units s/c +RIBAVIRIN 15mg/kg Group II b INTERFERON ALPHA 2b 3 Million Units s/c +RIBAVIRIN 15mg/kg Blood samples shall be collected and stored for post - hoc analysis of HCV RNA at day 1, 7 and 15(visit 2,3 \& 4).

   Patients will be reviewed for the hepatoprotection, anti viral activity and any adverse event every four weeks with following clinical and lab work.
