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 purpose of this study is to determine whether the administration of the dietary supplement Spermotrend improves spermatogenesis parameters in subjects with male infertility unrelated to major testicular conditions. The duration of this double-blind placebo controlled phase 3 clinical trial will be 24 weeks. The estimated number of males with infertility to be recruited and randomized for the study is 86.
The purpose of the study is to assess the efficacy of Oncoxin+Viusid administration in the treatment of rheumatoid arthritis. The duration of this double-blind placebo controlled phase 3 clinical trial will be 12 weeks. The estimated number of persons with rheumatoid arthritis to be recruited and randomized for the study is 86. The primary outcome measure: DAS28 score will be assessed at the end of the study.
The purpose of the study is to evaluate whether Oncoxin, a nutritional supplement, improves the clinical and ultrasonographic results in comparison with placebo during 24 weeks of treatment.
The objectives of this study are to estimate the efficacy and safety of the daily administration for 6 months of 5 mg versus 10 mg. A 6 month follow-up of subjects is carried out to estimate how the effects of mifepristone are kept in time. The hypothesis of this study is that both mifepristone doses reduce the volume of the myoma up to 50% in six months treatment.
The purpose of the study is to evaluate whether the addition of Diamel, a nutritional supplement, to hypocaloric diet and exercise could improve the histological results (steatosis, necro-inflammatory activity and fibrosis), insulin resistance, aminotransferase levels and anthropometric measures in comparison with a placebo-controlled group with hypocaloric diet and exercise during 52 weeks of treatment in patients with nonalcoholic steatohepatitis.
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.
