Addendum (from ABBV/ENTA standpoint): Inasmuch as GILD is apparently not seeking approval for an 8-week or shorter regimen of Sovaldi + GS-5816, there is no reason for GT1 patients, specifically, to prefer Sovaldi + GS-5816 to Sovaldi + Ledipasvir.
Thus, the Sovaldi + GS-5816 regimen does not present a competitive threat to ABBV/ENTA’s 3-DAA regimen, although it figures to compete with ABBV/ENTA’s pan-genotypic 2-DAA combination of ABT-493 + ABT-530.
