Retreatment of chronic hepatitis C patients who failed previous therapy with directly acting antivirals: A multicenter study

Aim of the study: The current study aimed to evaluate the efficacy of different DAAs regimens in the treatment of chronic hepatitis C (CHC) Egyptian patients who failed to achieve SVR after their treatment with SOF-based regimens. Methods: This was a retrospective observational multicenter study that included CHC patients that failed to achieve cure on SOF-based regimens who were re-treated using different DAAs regimen and were allocated according to national guidelines for the treatment of hepatitis C. Primary outcome was to assess the SVR12 rate among prior non-responders after retreatment with a second course of DAAs. Results: Our study included 172 patients who failed to achieve SVR after treatment with SOF-based treatment regimen [age: 51.2 +/- 11.3, 58.7% men]. Included patients were retreated using SOF/DCV/RBV, SOF/ r/PAR /OMB /RBV, SOF/DCV/SIM, SOF/LDV +/- RBV or SIM/SOF. SVR12 was successfully attained in 95.35% (164/172) of the included non-responders. Conclusion: The current multicenter study proved the efficacy of various DAAs regimens issued by the National Committee for Control of Viral Hepatitis for retreatment of relapsed CHC Egyptian patients.
