The raw data in the PR are not new. The data I quoted came from their new analysis of old data (SPRINT 1). The trial patients were entirely treatment-naive. Nevertheless, the PR uses the term null-responders for those patients who achieved less than one log drop in HCV counts after 4 wks of SOC. A null-responder was normally reserved for treatment-experienced patients who did not achieve 2 log drop at 12 wk treatment point.
