About this study

Official title: Open-Label Multi-Center Single Arm Clinical Trial to Study the Efficacy and Safety of the Elbasvir/ Grazoprevir 50/100 mg Fixed Dose Combination Once Daily in Patients With Chronic HCV GT1b Infection Associated With Metabolic Syndrome

This is a multi-center, open-label trial of Elbasvir/ Grazoprevir 50/100 mg fixed dose combination 12 week treatment aimed to evaluate SVR12 in treatment naïve patients with chronic hepatitis C (genotype 1b) infection, associated with of metabolic syndrome. The study to be conducted in conformance with Good Clinical Practices.

A total of 60 subjects will be studied at 2 sites in the Republic of Kazakhstan.

Males and Females treatment naïve patients with CHC genotype 1b infection associated with metabolic syndrome (MS), 18-70 years of age, with or without severe fibrosis / compensated cirrhosis will be enrolled. SVR 12 (primary endpoint) will be evaluated. Patients will be stratified by fibrosis stage and presence of metabolic syndrome components. Interim Analysis will be performed in order to estimate viral kinetics, applicability of SVR4 and durability of SVR12 by evaluation of virologic response at week 4 and 8 of treatment and follow-up at week 4 (SVR 4) and 24 will be performed - this will be a descriptive summary only without hypothesis testing.

The main hypothesis is that 12-week therapy with MK-5172 in combination with MK-8742 for treatment-naïve patients with HCV genotype 1b with metabolic syndrome is not notably worse than the same course for treatment-naïve patients with HCV genotype 1b without metabolic syndrome.

Read the detailed description

60 treatment-naïve subjects with chronic hepatitis C genotype 1b infection associated with metabolic syndrome (MS), with or without severe fibrosis/compensated cirrhosis will be enrolled, males and females of 18-70 years of age.

Subjects will fulfill the following study visits: Day 1 (screening), Day 7, Week 2, Week 4, Week 8, Week 12, Week 24, Week 36.

Eligibility criteria re-checked, informed consent signed and medical history will be gathered on Day 1.

Treatment allocation and review study medication diary will be made on Day 7. Physical Examinations will be fulfilled on Day 1, Day 7, Week 4 and Week 12. Subject Confirmation of Birth Control and Review (Serious) Adverse Events will be made on every visit of subject.

Laboratory evaluations will include common blood analysis, urinalysis, biochemical blood analysis, Thyroid-stimulating hormone (TSH) and Т4 free, antigen testings (aHBs, HBsAg, HbeAg, aHDV, aHAV, aHEV, ANA, AMA, aHIV), HCV RNA (quantitative), HCV genotyping, Urine Pregnancy Test (females of child bearing potential only), Transient elastography, Calculation of APRI, Ultrasonography (of liver, gall bladder, spleen, pancreas), Upper GI Endoscopy.

Patients will be stratified by fibrosis stage and presence of metabolic syndrome components. Interim Analysis will be performed in order to estimate viral kinetics, applicability of SVR4 and durability of SVR12 by evaluation of virologic response at week 4 and 8 of treatment and follow-up at week 4 (SVR 4) and 24 will be performed - this will be a descriptive summary only without hypothesis testing.

Primary objectives:

  • To demonstrate efficacy of 12 weeks therapy with MK-5172 (grazoprevir) in combination with MK-8742 (elbasvir) in treatment naïve patients with chronic hepatitis C (genotype 1b) with metabolic syndrome compared to patients without metabolic syndrome, as assessed by the proportion of subjects achieving SVR12, defined as HCV RNA < LLOQ (either TD[u] or TND) 12 weeks after the end of all study therapy.

Secondary objectives:

  • To evaluate efficacy of 12 weeks therapy with MK-5172 in combination with MK-8742 in treatment naïve patients with chronic hepatitis C (genotype 1b) with metabolic syndrome compared to patients without metabolic syndrome, dependent on fibrosis stage, as assessed by the proportion of subjects achieving SVR12, defined as HCV RNA < LLOQ (either TD[u] or TND) 12 weeks after the end of all study therapy.
  • To evaluate efficacy of MK-5172 in combination with MK-8742 in treatment naïve patients with chronic hepatitis C (genotype 1) combined with metabolic syndrome dependent on presence of the separate components of metabolic syndrome, as assessed by the proportion of subjects achieving SVR24, defined as HCV RNA < LLOQ (either TD[u] or TND) 12 weeks after the end of all study therapy.
  • To evaluate efficacy of 12 weeks therapy with MK-5172 in combination with MK-8742 in treatment naïve patients with chronic hepatitis C (genotype 1b) with metabolic syndrome compared to patients without metabolic syndrome, as assessed by the proportion of TN subjects achieving undetectable (TND) HCV RNA and HCV RNA < LLOQ at Week 2, 4, 8 and Follow-Up Week 4 (SVR 4).
  • To evaluate efficacy of 12 weeks therapy with MK-5172 in combination with MK-8742 in treatment naïve patients with chronic hepatitis C (genotype 1b) with metabolic syndrome compared to patients without metabolic syndrome, as assessed by the proportion of subjects achieving SVR24, defined as HCV RNA < LLOQ (either TD[u] or TND) 24 weeks after the end of all study therapy.
  • To evaluate safety profile / adverse events of 12 weeks therapy with MK-5172 in combination with MK-8742 in treatment naïve patients with chronic hepatitis C (genotype 1b) with metabolic syndrome

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. SVR12 evaluation

What is this clinical trial studying?

A Phase 3 study testing Elbasvir/ Grazoprevir 50/100 mg fixed dose combination in people with Chronic Hepatitis C Genotype 1B and Metabolic Syndrome, run by Institute Of Cardiology & Internal Diseases, Kazakhstan at 1 site in Kazakhstan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Kazakhstan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SVR12 evaluation (time frame: 12 weeks after the end of all study therapy (treatment success).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2017.
