Medivir AB (OMX: MVIR) announces that results from the phase II COSMOS clinical study were published July 28 in The Lancet, demonstrating that 92 percent of genotype 1 chronic hepatitis C virus adult patients treated with simeprevir in combination with sofosbuvir achieved sustained virologic response 12 weeks after the end of treatment (SVR12). The study included patients with compensated cirrhosis and prior null response to treatment with pegylated interferon and ribavirin.

According to results from the study, the all-oral, interferon-free treatment regimen with simeprevir and sofosbuvir resulted in consistent SVR12 rates regardless of degree of fibrosis, and was an effective and well-tolerated therapeutic regimen in both treatment-naïve and prior null-responder patients.

“The Lancet publication of the COSMOS data on World Hepatitis Day gives further recognition to these revolutionizing treatment results. I hope that this will contribute to helping more patients around the world to get cured.” says Henrik Krook, EVP Commercial, Medivir AB.

Based on the findings from the COSMOS study, our partner Janssen in April initiated the phase III studies OPTIMIST-1 and OPTIMIST-2 examining the safety and efficacy of simeprevir and sofosbuvir without interferon or ribavirin for the treatment of chronic genotype 1 hepatitis C infection.
