Brief Summary

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. Velpatasvir has pH dependent absorption. At higher pH the solubility of velpatasvir decreases. It has been shown that in subjects treated with proton pump inhibitors (PPIs) such as omeprazole, the absorption of velpatasvir is reduced by 26-56%, depending on the dose of omeprazole, concomitant food intake, and timing/sequence of velpatasvir vs. omeprazole intake. As a result, concomitant intake of PPIs with velpatasvir is not recommended. For a number of reasons, the prohibition of PPI use with velpatasvir is a clinically relevant problem. First, PPI use is highly frequent in the HCV-infected subject population with prevalences reported up to 40%. Second, PPIs are available as over-the-counter medications and thus can be used by subjects without informing their physician. Third, although HCV therapy is generally well tolerated, gastro-intestinal symptoms such as abdominal pain and nausea are frequently reported, which my lead to PPI use. One solution of this problem could be the use of other acid-reducing agents such as H2-receptor antagonists or antacids. In general, they have a less pronounced effect on intragastric pH, and are considered less effective than PPIs by many patients and physicians. A second solution would be the choice of another HCV agent or combination that is not dependent on low gastric pH for its absorption such as daclatasvir. Daclatasvir, however, is not a pan-genotypic HCV agent and may be less effective against GT 2 and 3 infections than velpatasvir. Second, not all subjects have access to daclatasvir, depending on health insurance company or region where they live. A third solution, and the focus of this COPA study, is to add a glass of the acidic beverage cola at the time of velpatasvir administration in subjects concurrently treated with PPIs. This intervention has been shown to be effective for a number of drugs from other therapeutic classes who all have in common a reduced solubility (and thus reduced absorption) at higher intragastric pH, namely erlotinib, itraconazole, ketoconazole. The advantages of this approach are: (1) only a temporary decrease in gastric pH at the time of cola intake; the rest of the day the PPI will have its therapeutic effect (2) cola is available worldwide (3) the administration of cola can be done irrespective to the timing of PPI use.

Outcome Measures

Primary Outcomes (1)

  • Bioequivalence AUC0-inf

    Determination of velpatasvir AUC0-inf by noncompartmental analysis. Descriptive statistics for the plasma concentrations of velpatasvir at each sampling time. Descriptive statistics for each PK parameter per treatment (geometric mean + CV%). Geometric Mean Ratios and 90% confidence intervals of pharmacokinetic parameters of A (Test 1) vs. C (Reference) and of B (Test 2) vs. C (Reference). AUC0-inf geometric mean ratios with a 90% Cl falling entirely within the range of 0.7 to 1.43 are considered bioequivalent.

    21 days

Secondary Outcomes (3)

  • Safety and tolerability of Epclusa in healthy volunteers

    21 days

  • Subject is in good age-appropriate health condition as established by medical history, physical examination, and electrocardiography, results of biochemistry, hematology and urinalysis testing within 4 weeks prior to Day 1. Results of biochemistry, hematology and urinalysis testing should be within the laboratory's reference ranges (see Appendix A). If laboratory results are not within the reference ranges, the subject is included on condition that the Investigator judges that the deviations are not clinically relevant.
