Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 99 years (Adult, Older Adult)

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 Virologic Response 12 Weeks Post-treatment (SVR12) in Each Treatment Arm
Time Frame: 12 weeks after last dose
SVR12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification (< LLOQ) 12 weeks after the last dose of study drug.
12 weeks after last dose
Number of Participants With Adverse Events
Time Frame: Screening until 30 days after last dose
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The investigator assessed the relationship of each event to the use of study drug as either reasonable possibility or no reasonable possibility. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the subject and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent events (TEAEs/TESAEs) are defined as any event that began or worsened in severity after the first dose of study drug. For more details on adverse events please see the Adverse Event section.
Screening until 30 days after last dose

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 On-treatment Virologic Failure in Each Treatment Arm
Time Frame: Up to 12 or 24 weeks after first dose
On-treatment virologic failure was defined as quantifiable HCV RNA throughout the entire treatment period with at least 6 weeks of treatment, confirmed HCV RNA greater than the LLOQ after previously having unquantifiable HCV RNA, or a confirmed increase from nadir of at least one log10 in HCV RNA during treatment.
Up to 12 or 24 weeks after first dose
Percentage of Participants With Post-treatment Relapse Within 12 Weeks Following End of Treatment in Each Arm
Time Frame: Up to 12 weeks after first dose
Post-treatment relapse was defined as defined as confirmed HCV RNA > LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA < LLOQ at the end of treatment.
Up to 12 weeks after first dose
