Review article: novel antivirals for hepatitis C-sofosbuvir/velpatasvir/voxilaprevir, glecaprevir/pibrentasvir

Abstract

Background: In 2017, the hepatitis C treatment regimens sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) and glecaprevir/pibrentasvir (G/P) received approval from the U.S. Food and Drug Administration. Although both SOF/VEL/VOX (NS5B polymerase inhibitor/NS5A inhibitor/NS3/4A protease inhibitor) and G/P (NS3/4A protease inhibitor/NS5A inhibitor) are pangenotypic regimens, they are indicated for distinct subsets of patients with hepatitis C.

Aim: To compare and contrast available safety and efficacy data for SOF/VEL/VOX and G/P and outline their clinical utility.

Methods: For each of the regimens, this review outlines the indications, safety information, and the major clinical studies in which SOF/VEL/VOX and G/P were evaluated.

Results: SOF/VEL/VOX is positioned as a salvage regimen for patients previously treated with NS5A inhibitors and for genotype 1a- and 3-infected patients who had failed other sofosbuvir-containing regimens. G/P is the first pangenotypic regimen with an 8-week duration for treatment-naïve, non-cirrhotic patients, and it is indicated for patients with any genotype who have advanced kidney disease, including those on dialysis.

Conclusion: The addition of SOF/VEL/VOX and G/P to existing hepatitis C treatment options will expand the number of patients who are eligible for and responsive to treatment, thus increasing the possibility of eliminating hepatitis C as a public health issue.
