Summary– Patients with chronic HCV genotype 4 infection were successfully

treated with a 12 week course of LDV/SOF• SVR12 was 100% for patients who received all 12 weeks of study

drugs, irrespective of previous treatment status and underlying liver fibrosis

• All patients on therapy had HCV RNA below the lower limit of quantification by W4

– This is the first report of a single-pill, all-oral, interferon-free, ribavirin-free treatment for patients with HCV genotype 4.

– Limitations• Small sample size• No randomisation
