Triple Combination DAAs for Treating HCV GT1b Subjects

May 11, 2017 updated by: Humanity and Health Research Centre

Triple Combination DAAs for Ultra Short Duration Therapy for HCV Genotype 1b in Chinese (SODAPI II Study)

There is only one kind of treatment (simeprevir 150 mg + sofosbuvir 400 mg+daclatasvir 60 mg) in this study but the treatment duration may be different depending on patients' response to the antiviral therapy and whether patients have liver cirrhosis. If patients have no cirrhosis and the HCV viral load on day 2 is <500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 3 weeks, otherwise the treatment duration is 4 weeks. If patients have cirrhosis and the HCV viral load on day 2 is <500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 6 weeks, otherwise the treatment duration will be 8 weeks.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. HCV RNA positive >2000 IU/ml or NAT POC positive
  2. Genotype 1b
  3. CP score ≤6

Exclusion Criteria:

  1. Pregnant or nursing female or male with pregnant female partner
  2. Hematologic or biochemical parameters at Screening outside the protocol- specified requirements
  3. Active or recent history (≤ 1 year) of drug or alcohol abuse
  4. Hepatocellular carcinoma or other malignancy (with exception of certain resolved skin cancers)
  5. History or current evidence of any condition, therapy, laboratory abnormality or other circumstance that might confound the results of the study, or interfere with the subject's participation for the full duration of the study, such that it is not in the best interest of the subject to participate.

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
Proportion of participants with plasma HCV viral load below the lower limit of quantification for 12 weeks after treatment completion (SVR12)
Time Frame: Post treatment Week 12
SVR12 is defined as HCV RNA < lower limit of quantification (LLOQ) 12 weeks after last dose of study drug.
Post treatment Week 12

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
Frequency and severity of adverse events
Time Frame: Baseline up to Week 24
Baseline up to Week 24
Proportion of participants with unquantifiable HCV viral load at specified time points during and after treatment
Time Frame: Baseline up to Week 24
Baseline up to Week 24
Kinetics of circulating HCV RNA during treatment and after treatment discontinuation
Time Frame: Baseline up to Week 24
Baseline up to Week 24
Proportion of participants with on-treatment virologic breakthrough and relapse
Time Frame: Baseline up to Week 24
Viral breakthrough is defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) during treatment, but did not achieve a sustained virologic response (SVR). Viral relapse is defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) within 4 weeks of end of treatment, but did not achieve an SVR up to 24 weeks.
Baseline up to Week 24
