Study summary

To evaluate the safety and efficacy of a daily, fixed-dose, 8-week course combination of Elbasvir/Grazoprevir in treatment-naïve, non-cirrhotic patients who are mono-infected with hepatitis C, genotype 4.

Read the detailed description

The treatment of hepatitis C has gone through significant advances in the last few years with the development of direct-acting antivirals "DAAs." Since 2013, many DAAs have been approved for the treatment of HCV with excellent efficacy and safety profiles. The major hurdle in treating patients on a large scale is the high cost of the current treatment regimens. Multiple approaches have been proposed, among them, a shortened treatment regimen of 6 to 8 weeks rather than the standard 12-week-regimen. The strategy of shortening the treatment will help in reducing the cost by 33% to 50%. Thus, it will increase the availability of the treatment to more patients.

Zepatier is a combination drug of Elbasvir (EBR), an NS5A inhibitor, and Grazoprevir (GZR), a potent NS3/4A inhibitor. This study is being proposed to address two main issues. First, collecting information on the safety and efficacy of a shortened course of zepatier (8 weeks instead of the standard 12 weeks) in patients who are treatment-naïve, non-cirrhotic and mono-infected with HCV. Second, to investigate whether this course provides similar clinical outcomes to the standard regimen in HCV-Genotype 4, which is the most common genotype in Saudi Arabia.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

What researchers measure

Primary outcomes

  1. Sustained virologic response at 12 weeks after the end of intervention (SVR-12).

    Viral RNA below the level of detection at 12 weeks after the end of the intervention. (Hepatitis C viral load evaluated by polymerase chain reaction (PCR) with a cutoff of 20 IU/mL for detectability.)

    Time frame: At 12 weeks after the end of intervention.

Secondary outcomes

  1. Sustained virological response at 4 weeks after the end of intervention (SVR-4).

    Hepatitis C viral RNA below the level of detection at 4 weeks after the end of the intervention.

    Time frame: At 4 weeks after the end of intervention.

  2. Serious and treatment-related adverse events.

    Number of patients with serious and treatment-related adverse events based on the common terminology criteria (CTCAE 4.03), or death during the follow-up period.

    Time frame: From the first day of intervention until the end of week 4 after the intervention is finished.

  3. Changes in the quality of life: Hepatitis Quality of Life Questionnaire (HQLQ)

    To assess this outcome, a self-administered questionnaire called the "Hepatitis Quality of Life Questionnaire" (HQLQ) will be used. The HQLQ is composed of 7 domains; the physical and mental components (PCS and MCS, respectively), a self-evaluated health transition item (SET), and four hepatitis-related items. The latter include general health distress (HD), psychological well-being (PWB), hepatitis-specific functional limitations (HLIM), and hepatitis-specific health distress (HHD) sub-scales. Higher numbers on each component/scale represent better results (e.g., better physical, emotional, and psychological functioning, and little to no limitations in these aspects). Higher scores on the self-evaluated transition item, however, represent less favorable results. These assessments will take place over three occasions. The first will be upon initiating the treatment, the second will be during/by the end of treatment, and the last will take place 12 weeks after the end of treatment.

    Time frame: Quality of life evaluations will take place over three occasions. The first will be at baseline (upon treatment initiation), the second will be during treatment/at the end of treatment, and the last will be 12 weeks after the end of treatment

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 20, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
