According to the results reported on ClinicalTrials.gov, this trial (NCT03118843) enrolled 31 participants, all of whom received a combination treatment referred to as SOF/VEL/VOX (a single group with no comparison group). All 31 participants completed the trial — none dropped out. The trial was primarily measuring two things: whether participants' hepatitis C virus (HCV) levels fell below a detectable threshold 12 weeks after finishing treatment (known as SVR12, a standard way of checking whether the virus is still detectable in the blood), and whether anyone had to permanently stop taking the study medication due to a bad reaction. The reported data shows that 100% of participants (all 31 people) had HCV levels below the detectable limit at both 4 weeks and 12 weeks after finishing treatment. The reported data also shows that 0% of participants permanently stopped the study medication due to an adverse event (an unwanted reaction). For the secondary measurements, the reported data shows that 0% of participants experienced what the trial defined as "virologic failure" — meaning the virus did not rebound or persist during treatment in any participant. During treatment itself, the proportion of participants with virus levels below the detectable limit rose over time, with figures reported at 51.6%, 96.8%, and 100% at successive measurement points. The reported data also includes measurements of how much HCV levels changed from the starting point during treatment, expressed as a log10 reduction (a technical way of describing a large drop in virus levels) — with reductions of around 5.16 to 5.34 log10 IU/mL reported across the on-treatment time points.
