Identified gaps in the literature include; lack of accurate epidemiological data on incident infection, untreated chronic HCV infection particularly in PWUD living outside Dublin and those not engaged with OST.
D3FEAT is an international open-label study that recruited treatment-naïve participants with recent injecting drug use (previous 6 months) and/or receiving OST with chronic HCV G1 infection between June 2016 and February 2017 in seven countries.
In this analysis of the ASTRAL trials (non-opioid substitution therapy [OST], n = 984; OST, n = 51) evaluating the once-daily, pan-genotypic regimen of sofosbuvir/velpatasvir for hepatitis C virus infection, OST did not impact completion, adherence, sustained virologic response (SVR12), or safety.
