EU approves change to authorization of Maviret in hepatitis C genotype 3.- AbbVie

AbbVie announced that the European Commission has approved a change to the marketing authorization for Maviret (glecaprevir/pibrentasvir) to shorten once-daily treatment duration from 12 to 8 weeks in treatment-naïve, compensated cirrhotic, chronic hepatitis C (HCV) patients with genotype (GT) 3 infection. Maviret was already indicated as an 8-week, pan-genotypic (GT1-6), once-daily regimen for treatment-naïve HCV patients without cirrhosis, and as an 8-week, once-daily regimen for treatment-naïve GT 1, 2, 4, 5 and 6 HCV patients with compensated cirrhosis.The EC approval is supported by data from the Phase IIIb EXPEDITION-8 study. The Phase IIIb EXPEDITION-8 study evaluated the safety and efficacy of MAVIRET in treatment-naïve chronic HCV patients with compensated cirrhosis across all major genotypes (GT1-6). The results have been reported for GT1, 2, 3, 4, 5, and 6 (n=343) patients and showed that with 8 weeks of MAVIRET, 97.7 percent (n=335/343) of GT1- 6 patients achieved a sustained virologic response 12 weeks after treatment (SVR12) (ITT). For patients with GT3, the SVR12 rate was 95.2% (n= 60/63) (ITT). To date, one virologic failure has been reported and no patients have discontinued treatment due to adverse events. In the study, most patients that did not achieve SVR12 were lost to follow up versus experiencing treatment failure, and no new safety signals were identified.
