71. Hepatitis web study Simeprevir + Sofosbuvir +/- Ribavirin for HCV GT 1 COSMOS Trial: Key Points High Rates of SVR even in difficult to treat groups, including patients compensated cirrhosis and prior nonresponse to therapy Rapid virologic response (RVR) did not predict SVR 12 Addition of ribavirin did not clearly improve SVR rates Extending treatment to 24 weeks did not clearly improve SVR rates, except possibly in patients with prior relapse and advanced fibrosis Patients with baseline G80K (Gln80Lys) had high SVR rates, including those with compensated cirrhosis Ribavirin did not significantly impact SVR in patients with baseline G80K Regimen well tolerated: fatigue, headache, and nausea were most common side effect Phase 3 studies underway with simeprevir + sofosbuvir in OPTIMIST program Source: Lawitz E, et al.
