In summary, SURVEYOR-II Part 3 enrolled and treated some of the most difficult-to-cure HCV patients: those with GT3 infection and prior treatment experience and/or cirrhosis. Overall, the fixed-dose combination of once daily RBV-free G/P was well-tolerated and demonstrated high SVR12 rates (≥95%) in treatment-naive patients with cirrhosis treated for 12 weeks, and treatment-experienced patients with or without cirrhosis treated for 16 weeks. Therefore, G/P provides an efficacious and well tolerated once-daily RBV-free treatment option for patients with HCV genotype 3 and prior treatment experience and/or cirrhosis.

Abstract
BACKGROUND:
This study assessed the efficacy and safety of ribavirin (RBV)-free coformulated glecaprevir/pibrentasvir (G/P) in patients with hepatitis C virus (HCV) genotype (GT) 3 infection with either prior treatment experience and/or compensated cirrhosis, a patient population with limited treatment options.

METHODS:
SURVEYOR-II, Part 3 was a partially-randomized, open-label, multicenter, phase 3 study. Treatment-experienced (prior interferon (IFN) or pegIFN ± ribavirin or SOF plus ribavirin ± pegIFN therapy) patients without cirrhosis were randomized 1:1 to receive 12 or 16 weeks of G/P (300 mg/120 mg) once daily. Treatment-naïve or treatment-experienced patients with compensated cirrhosis were treated with G/P for 12 or 16 weeks, respectively. The primary efficacy endpoint was the percentage of patients with sustained virologic response at post-treatment week 12 (SVR12). Safety was evaluated throughout the study.

RESULTS:
There were 131 patients enrolled and treated. Among treatment-experienced patients without cirrhosis, SVR12 was achieved by 91% (20/22; CI 72-97) and 95% (21/22; CI 78-99) of patients treated with G/P for 12 or 16 weeks, respectively. Among those with cirrhosis, SVR12 was achieved by 98% (39/40; CI 87-99) of treatment-naïve patients treated for 12 weeks, and 96% (45/47; CI 86-99) of patients with prior treatment experience treated for 16 weeks. No adverse events (AEs) led to discontinuation of study drug and no serious AEs were related to study drug.

CONCLUSIONS:
Patients with HCV GT3 infection with prior treatment experience and/or compensated cirrhosis achieved high SVR12 rates following 12 or 16 weeks of treatment with G/P. The regimen was well tolerated.
