Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Enrolled participants were treated orally with SOF plus a fixed dose combination of Sofosbuvir/Ombitasvir/Paritaprevir/ Ritonavir plus Ribavirin (OBV/PTV/r plus RBV), which was administered orally based on the participants' tolerability. The primary end point was a sustained virological response (HCV RNA level < 15 IU/ mL), observed 12 weeks after the end of the treatment (SVR12).

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

ACTIVE_COMPARATOR: Cirrhotic Participants
The experienced participants(113 participants) who failed prior DAA treatments. They were allocated to cirrhotic (30 participants) and treated for 12 weeks.
Drug: SOF plus (OBV/PTV/r) plus RBV
They were given SOF in a dose of 400 mg/day, and a fixed dose combination of OBV (25 mg), PTV (150 mg), and r (100 mg) taken with food once daily. RBV was supplied in 200 mg capsules, and the recommended dose was 600 mg/ day to reach 1200 mg/day based on patient's body weight and tolerability.
Other Names:
  • Sovaldi is a trade name of sofosbuvir
  • Paritaprevir (ABT-450) is inhibitor of the NS3-4A serine protease

Drug: SOF plus (OBV/PTV/r) plus RBV
They were given SOF in a dose of 400 mg/day, and a fixed dose combination of OBV (25 mg), PTV (150 mg), and r (100 mg) taken with food once daily. RBV was supplied in 200 mg capsules, and the recommended dose was 600 mg/ day to reach 1200 mg/day based on patient's body weight and tolerability.

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 is defined as hepatitis C virus ribonucleic acid (HCV RNA) level < 15 IU/ml 12 weeks after the last dose of drugs.
12 weeks after last dose
Number of Participants With Adverse Events in Each Treatment Arm
Time Frame: Screening up to 12 weeks after last dose]
An adverse event (AE) is defined as any untoward medical occurrence in a participant clinical investigation after administering a pharmaceutical drugs Serious adverse event (SAE) is an event that results in death, life-threatening, requires hospitalization, or significant disability/incapacity
Screening up to 12 weeks 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 Viral relapse
Time Frame: Up to 12 weeks after last dose
Viral relapse was HCV RNA level undetectable at End of Treatment (EOT) (≤ 15 IU/ml), but detectable HCV RNA ( > 15 IU/ml) levels 12 weeks after planned EOT.
Up to 12 weeks after last dose

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2017

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
