About this study

Epclusa® is a pan-genotypic, once-daily tablet for the treatment of chronic hepatitis C virus (HCV) infection containing the NS5B- polymerase inhibitor sofosbuvir (SOF, nucleotide analogue) 400 mg and the NS5A inhibitor velpatasvir (VEL) 100 mg.

For patients with swallowing difficulties, administration of whole tablets can be problematic. In addition, HCV patients that are hospitalized (at intensive care units) due to severe illness (co-infections/ liver failure) might not be able to swallow medication. Therefore it is useful to know whether it is possible to administer SOF/VEL through a different route, like a feeding tube.

In daily practice, information about the safety and efficacy of crushed tablets is lacking which might result in interruption or discontinuation of expensive HCV therapy. However, it is not recommended to interrupt treatment because there is no evidence about the efficacy of the therapy after discontinuation (and restart).

Currently, patients and healthcare professionals are crushing SOF/VEL tablets without information about efficacy and safety. Depending on the biopharmaceutical characteristics of a drug formulation, crushing tablets can lead to altered pharmacokinetics of drugs.

It is important to know whether pharmacokinetic parameters are influenced by crushing of tablets; both a decrease and an increase in exposure may occur. A decrease of the plasma concentrations of SOF and/or VEL potentially reduces the therapeutic effect of the drugs. Higher doses or switching to other HCV-drugs might be needed. In contrast, in case a higher Cmax,ss and/or exposure occurs there might be an increased risk of toxicity.

As a result, crushing the drug is a contra-indication based on the available data.

Therefore this study will be conducted to investigate whether a crushed SOF/VEL tablet is bioequivalent to SOF/VEL as a whole tablet.

What is being measured

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

  1. AUC

    Measured: Up to 24 hours after administration

  2. Cmax

    Measured: one dosing interval after administration of SOF/VEL (up to 24 hours)

Secondary outcomes (1)
  1. Adverse events

    Measured: During the entire conduct of the study, maximum of two weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing sofosbuvir/velpatasvir tablet and sofosbuvir/velpatasvir crushed in people with HCV, run by Radboud University Medical Center at 3 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 4 inclusion and 4 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: withdrawn, as of the sponsor's last update on 7 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Netherlands, Germany. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

AUC (time frame: Up to 24 hours after administration). The study lists 2 primary outcomes in all. 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 NCT03389061, which also lists 1 linked publication.

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 Dec 2020.
