Gane, M.D.: Sofosbuvir for Untreated Chronic Hepatitis C Contamination Previously As much as 170 million persons are chronically infected with the hepatitis C virus worldwide, and more than 350,000 die each year from liver disease caused by HCV.1,2 Estimates of the number of persons in the United States who’ve chronic HCV infection range between 2.7 million to 5.2 million.3,4 For previously untreated situations of HCV genotype 1 infection , the current standard of care is 12 to 32 weeks of an oral protease inhibitor combined with 24 to 48 weeks of peginterferon alfa-2a plus ribavirin, with the duration of therapy guided by the on-treatment response and the stage of hepatic fibrosis.8 Although 60 to 80 percent of previously untreated patients who undergo treatment with these regimens in clinical trials experienced a sustained virologic response,6,7,9,10 a large number of patients go untreated owing to absolute and relative unwillingness or contraindications to receive interferon.In the trial, ACE-031 was generally well-tolerated with quick and sustained effects on muscle, bone and fat. Preliminary results out of this randomized, placebo-controlled study were presented at the 15th International Congress of the global world Muscle Culture in Kumamoto, Japan.1 to 3 mg/kg distributed by subcutaneous injection every two or a month for a complete of three or two dosages, respectively, over a four week period. Topics were followed for 12 weeks after their last dose. Lean mass and muscles volume of the thigh were obtained at baseline and weeks 5, 8 and 16. Additional PD endpoints included biomarkers of bone formation, bone resorption and fats metabolism, and measures of muscle tissue function and strength. Although this safety study was not driven to assess statistically significant adjustments in these PD endpoints, multiple exploratory statistical analyses had been performed on the info presented at the conference.
