MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The majority of HCV patients can be cured with combinations of direct-acting antivirals (DAAs); however, there is still 5 to 10% of patients who relapse after treatment with DAAs for whom there are currently no approved therapeutic options available.

In these two international phase 3 studies, we have demonstrated that a single tablet triple regimen combining sofosbuvir, velpastasvir and voxilaprevir (a pangenotypic protease inhibitor) for 12 weeks cured 96% of the patients who had relapsed following prior treatment with DAA regimens including NS5A inhibitors and 98% of the patients who had relapsed following prior treatment with DAA regimens without an NS5A inhibitor. These two studies demonstrate that a pangenotypic retreatment option for this patient population could be soon available.

MedicalResearch.com: What should readers take away from your report?

Response: Daily treatment with the single tablet regimen of sofosbuvir-velpatasvir-voxilaprevir for 12 weeks is highly effective and safe for patients infected with HCV of any genotype with or without compensated cirrhosis, who did not achieve a sustained virology response after treatment with DAA-based regimen, including NS5A inhibitors.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: This triple regimen has solved most of retreatment issues in DAAs failure. However in cirrhotic patients with multiple RASs (Resistant associated substitutions)others combination may be suitable like the association of sof/vel/vox plus ribavirin. This should be investigated in genotype 3 cirrhotic patients in order to achieve near 100% SVR .
