Participant Flow

A total of 41 participants were enrolled in the study, among them 40 participants (20 per panel) were randomized and treated. One participant was early terminated from the study, due to withdrawal of consent before randomization to study drug. All randomized participants received study drug and were included in the intent to treat (ITT) population.

SECONDARY outcome

Timeframe: 4 weeks after EOT (Week 4 of follow-up phase in Panel 1 and Panel 2) and 12 weeks after EOT (Week 12 of follow-up phase in Panel 1 and Panel 2)

Population: The ITT analysis set is defined as all participants who took at least 1 dose of SMV, LDV, or SOF.

SVR4 or SVR12 is defined as sustained virologic response 4 or 12 weeks after the actual EOT the participant has HCV RNA \<LLOQ detectable or undetectable.

Timeframe: Day 70 in Panel 1 and Day 56 in Panel 2

Population: The ITT analysis set is defined as all participants who took at least 1 dose of SMV, LDV, or SOF.

On-treatment failure is defined as participants who did not achieve SVR12 and with confirmed detectable HCV RNA at the actual end of treatment. This was to include participants with: 1) Viral breakthrough, defined as a confirmed increase of greater than (\>)1 log10 in HCV RNA from nadir, or confirmed HCV RNA of \>100 IU/mL in participants whose HCV RNA had previously been \<LLOQ while on treatment; 2) Other with confirmed detectable HCV RNA at the actual end of treatment (example, completed, discontinued due to AEs, withdrawal of consent).

Timeframe: Up to end of follow-up phase (Week 12 of follow-up phase) in Panel 1 and Panel 2

Population: The ITT analysis set is defined as all participants who took at least 1 dose of SMV, LDV, or SOF. Since the data was to be analysed in the participants who did not achieve SVR, but all the participants achieved SVR in the study. Therefore the data was not collected for this outcome measure.
