Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virological Response (SVR) at 24 Weeks After End of Treatment
Time Frame: 24 weeks after end of treatment (Week 72)
SVR was defined as the percentage of patients with undetectable HCV RNA. SVR rate was calculated as the number of participants with an undetectable HCV RNA divided by the number of participants of the respective participant population. The last single HCV RNA less than (<) 50 international units per millilitre (IU/mL) measured >=140 days after treatment end (i.e., >= 20 weeks after treatment end) was used to determine SVR. Participants without measurements in this time window were considered to be nonresponders.
24 weeks after end of treatment (Week 72)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Virological Response (Non-detectable Hepatitis C Virus-ribonucleic Acid [HCV RNA]) at End of Treatment (EOT)
Time Frame: EOT (Week 48)
Virological response at the end of study treatment was defined as the percentage of participants with undetectable HCV RNA. This response rate at end of treatment was calculated as the number of participants with undetectable HCV RNA divided by the number of participants of the respective participant population.
EOT (Week 48)
Percentage of Participants With Virological Response (at Least a 2-log 10 Decrease in HCV RNA as Compared With Baseline or Unquantifiable [Less Than {<} 600 International Unit/Milliliter {IU/mL}] or Undetectable HCV RNA [< 50 IU/mL]) at Week 12 and 24
Time Frame: Weeks 12 and 24
Virological response at Weeks 12 and 24 was computed as the percentage of participants with at least a 2-log 10 decrease in HCV RNA at Weeks 12 and 24 as compared with baseline or with an unquantifiable (< 600 IU/mL) or an undetectable HCV RNA test result (< 50 IU/mL) at Week 12 and at Week 24, calculated as the number of participants meeting this criterion divided by the number of participants of the respective participant population.
Weeks 12 and 24

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
