Results

The overall SVR rates of the ITT and mITT populations were 87.3% (95% confidence interval [CI] 80.2-92.6) (110/126) and 97.3% (95% CI 92.4-99.4) (110/113), respectively. In the mITT population, the percentages of patients with undetectable HCV RNA at 4, 8, and 12 weeks after the start of therapy were 92.9% (95% CI 86.5-96.9) (105/113), 99.1% (95% CI 95.2-100.0) (112/113), and 100.0% (95% CI 97.4-100.0) (113/113), respectively.

Baseline Characteristics

Results: The overall SVR rates of the ITT and mITT populations were 87.3% (95% confidence interval [CI] 80.2-92.6) (110/126) and 97.3% (95% CI 92.4-99.4) (110/113), respectively. In the mITT population, the percentages of patients with undetectable HCV RNA at 4, 8, and 12 weeks after the start of therapy were 92.9% (95% CI 86.5-96.9) (105/113), 99.1% (95% CI 95.2-100.0) (112/113), and 100.0% (95% CI 97.4-100.0) (113/113), respectively. Subgroup analyses of the mITT population showed no significant differences in SVR rates according to age, sex, HCV genotype (subtype), history of interferon-based therapy, baseline FIB-4 index, or baseline estimated glomerular filtration rate. In all subpopulations, the SVR rates were > 90%. There were no severe adverse events associated with the treatment.

Participant flow

A total of 126 patients with chronic hepatitis C due to HCV genotype 2 infection who were treated with the LDV/SOF regimen were enrolled. The sustained virological response (SVR) rate and safety were analyzed. SVR was assessed in the intention-to-treat (ITT) population as well as in the modified intention-to-treat (mITT) population, which excluded patients with non-virological failure, including those who dropped out before the SVR assessment.

Adverse events

None

Outcome measures

The LDV/SOF regimen showed high virological efficacy and acceptable safety in patients with HCV genotype 2 infection.
