SOF Plus DCV in Treating Chinese Treatment-experienced HCV Patients

March 16, 2018 updated by: Humanity and Health Research Centre

Efficacy and Safety of Sofosbuvir Plus Daclatasvir in Chinese Treatment-experienced Patients With Chronic Genotype 1b HCV Infection

For those chronic hepatitis C patients, who are interferon-ineligible or intolerant, there is a burning need for the development of pan-oral interferon-free regimen. The investigators examine the efficacy and safety of sofosbuvir, a NS5B nucleotide polymerase inhibitor and daclatasvir, an NS5A replication complex inhibitor in Chinese treatment-experienced cirrhosis patients with chronic G1b infection.

Study Overview

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

Chinese genotype 1b HCV treatment-experienced cirrhotic patients are recruited and treated with 12 weeks sofosbuvir 400 mg daily plus daclatasvir 60 mg daily. At baseline, liver stiffness measurement (LSM) using transient elastography (FibroScan®) is used to assess liver fibrosis and the single nucleotide polymorphism ofinterferon-λ 3 (IL-28, rs12979860, C or T) and IFLN4 (ss469415590, TT or ΔG) is determined. Serial measurement of plasma HCV RNA levels are performed with the use of the COBAS TaqMan real-time assay (Roche version 2.0), at baseline, Day 2,4 and 7, week 2,4 and 12, post-treatment week 12. The primary efficacy end point is a sustained virologic response 12 weeks after the end of 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

All

Description

Inclusion Criteria:

  1. Patients chronically infected with HCV Genotype-1b;
  2. Documented evidence of relapse after completion of previous course of interferon-based regimen with or without ribavirin;
  3. HCV RNA level greater than 10,000 IU/ml at screening;
  4. Patients with compensated cirrhosis are permitted.

Exclusion Criteria:

  1. Current or prior history: Clinically-significant illness (other than HCV) or any other major medical disorder that may interfere with treatment, assessment or compliance with the protocol; individuals currently under evaluation for a potentially clinically-significant illness (other than HCV) are also excluded;
  2. Screening ECG with clinically significant abnormalities;
  3. Laboratory results outside of acceptable ranges at screening;
  4. Infection with hepatitis B virus (HBV) or human immunodeficiency virus (HIV).

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 sustained virologic response 12 weeks after the end of treatment (SVR12)
Time Frame: Post treatment Week 12
SVR12 is defined as HCV RNA < the lower limit of quantitation (LLOQ) (15 IU/ml) 12 weeks following the last dose of study drug
Post treatment Week 12
