Effects of 12-week treatment with Sovodak in patients infected by genotype 1 hepatitis C virus

It has been shown that the combination therapy of Sofosbuvir-Daclatasvir (Sof/Dac) has a high rate of success in the treatment of patients. For the first time, a single pill of Sof/Dac has been formulated in Iran (Sovodak). In this regard, the present study was carried out aiming to investigate the safety and efficacy of Sovodak for 12 weeks during treatment of patients infected by genotype 1 hepatitis C virus (HCV). In this study, 50 patients (25 and 25 treatment-naïve and treatment-experienced patients, respectively) infected by HCV genotype 1 received Sovodak (1pill per day) for 12 weeks. Ribavirin was added for patients who had definitive evidence of liver cirrhosis. The sustained virological response (SVR12) was investigated 12 weeks after the end of the therapy. All 50 patients completed the treatment period. The mean age of patients was 54.40 ± 11.69 years, in addition, 60% and 90% of the patients were male and infected by HCV genotype 1b, respectively. After 4 and 12 weeks of treatment with Sovodak, the HCV ribonucleic acid (RNA) titer was undetectable in 82% and 100 % of the patients, respectively and 100% of them achieved SVR12. None of the subjects reported treatment discontinuation because of adverse events, however, 3 patients reported transient side effects including foot swelling, headache, and vomiting. The results of this study showed that once-daily Sovodak single-pill for 12 weeks is an effective and safe medicine for treating patients infected by HCV genotype 1
