About this study

Official title: Grazoprevir (MK-5172)+ Elbasvir (MK-8742) for the Treatment of Acute Hepatitis C Genotype 1/4. The Dutch Acute HCV in HIV Study (DAHHS-2)

New and recently EMA/FDA approved direct acting antiviral (DAA) combination therapies cure 95% or more of the patients chronically infected with HCV genotype 1 and 4. Grazoprevir (MK-5172) and elbasvir (MK-8742) combination therapy is such a, albeit not yet EMA/FDA approved combination DAA therapy.

It is likely that the synergistic effect of the host's immune response and antiviral therapy when given during the first 6 months of HCV infection makes antiviral therapy during acute HCV infection more effective. In this study the investigators would like to document that treatment of acute HCV with grazoprevir (MK-5172), elbasvir (MK-8742) is effective and can ben shortened from 12 to 8 weeks for HCV genotype 1 and 4 infection without substantial loss in efficacy.

Study design and intervention:

Prospective open label interventional clinical trial in which 80 acute HCV genotype 1 or 4 patients co-infected with HIV will receive 8 weeks of grazoprevir and elbasvir (a once-daily combination tablet).

Study population:

80 Adult HIV positive patients with an acute HCV genotype 1 or 4 infection from 10 HIV treatment centers in the Netherlands and Belgium will be included.

Primary endpoint: Sustained viral response (SVR) 12 weeks after the end of therapy in ITT study population (=genotype 1 and 4).

Read the detailed description

Rationale:

Over the last 2 years, the treatment of chronic HCV underwent an enormous change in a positive way. New and recently EMA approved direct acting antiviral (DAA) combination therapies cure as 95% or more of the patients chronically infected with HCV genotype 1 and 4. Grazoprevir (MK-5172) and elbasvir (MK-8742) combination therapy is such a combination DAA therapy. Two recent phase II and 1 phase III clinical trial showed that chronic HCV genotype 1 can be cured with 12 weeks of combination therapy with grazoprevir and elabsvir with a 97% cure in HIV-HCV co-infected patients in the phase III C-Edge co-infection study. However, none of these new HCV therapies have been well studied for the treatment of acute HCV and are therefore not registered for this indication. The only treatment approved for acute HCV is interferon. Interferon based therapy for the treatment of HCV has been shown to be much more effective when given during the acute phase of the HCV infection than at a time when the infection has become chronic. A likely explanation for this difference in success for acute versus chronic HCV therapy is a substantial immune response that is present during the acute phase of HCV infection, but becomes exhausted during chronic infection. This potent immune response is broadly targeted against various HCV epitopes and eradicates approximately 20% of HCV infections within the first 12 to 18 months of infection. However, spontaneous cure of HCV becomes very rare after the first 12 to 18 months of infection due to immune exhaustion. It is likely that the synergistic effect of the host's immune response and antiviral therapy when given during the first 6 months of HCV infection makes direct acting antiviral therapy during acute HCV infection more effective.

Objectives:

To document that treatment of acute HCV with grazoprevir (MK-5172), elbasvir (MK-8742) is effective. To show that, due to the host's immune response at the time of an acute HCV infection, the duration of therapy with grazoprevir (MK-5172) and elbasvir (MK-8742) for acute HCV genotype 1 and 4 infections can be shortened from 12 to 8 weeks without substantial loss in efficacy.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Grazoprevir/Elbasvir 100mg/50mg in people with Acute Hepatitis C and Human Immunodeficiency Virus, run by Erasmus Medical Center at 9 sites in 2 countries.

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 2 inclusion and 5 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: finished, as of the sponsor's last update on 8 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in Netherlands, Belgium. 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?

Yes. Results are posted in the registry (first posted 8 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SVR12 (Reinfection Not Considered Failure) (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02600325, which also lists 2 linked publications.

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 8 Jul 2019.
