There are about 64 clinical studies being (or have been) conducted in Cuba. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The pathogenesis of chronic hepatitis C (CHC) is associated to severe oxidative stress and non-selective immunological disturbance that leads to necro-inflammation and progression of fibrosis. Previous trials suggested that antioxidant and inmunostimulant therapies may have a beneficial effect. The purpose of the study is to evaluate whether Viusid, a nutritional supplement with hepatoprotective properties, could ameliorate the oxidative stress and modulate the immune response in patients with CHC and non-responders to pegylated interferon plus ribavirin, during 24 weeks of treatment.
The objectives of this study are to estimate the efficacy and safety of the daily administration of mifepristone 5 mg versus 10 mg for three months for the treatment of uterine fibroids. The hypothesis of the study is that both mifepristone doses reduce the volume of the myoma in about 40% after 3 months of treatment.
The purpose of the study is to evaluate whether Viusid, a nutritional supplement, in combination with diet and exercise improve the histological results (steatosis, necro-inflammatory activity and fibrosis) in comparison with diet and exercise, during 24 weeks of treatment.
The purpose of the study is to evaluate whether Viusid, a nutritional supplement, reduce the mortality and the complications (ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatic encephalopathy, gastrointestinal bleeding, sepsis and hepatocellular carcinoma) of patients with cirrhosis of the liver secondary to HCV infection in comparison with placebo, during 96 weeks of treatment.
