A Drug-Drug Interaction Study to Evaluate Drug Transporter Interactions

Registration Number
NCT03136237
Lead Sponsor
BioCryst Pharmaceuticals
Brief Summary

This is an open-label, three part study to evaluate the effect of BCX7353 on drug transporters as well as the effect of an inhibitor of drug transport on BCX7353.

Detailed Description

This is a single center, open-label, fixed-sequence, drug interaction study to evaluate the effect of BCX7353 on the pharmacokinetics of the P-gp substrate digoxin and the BCRP substrate rosuvastatin, as well as the effect of the P-gp inhibitor cyclosporine on the pharmacokinetics of BCX7353.

It is planned that 54 subjects will be enrolled into 3 cohorts of 18 subjects each. Cohort 1 will evaluate the effects of multiple doses of BCX7353 on single-dose pharmacokinetics of digoxin. Cohort 2 will evaluate the effect of multiple doses of BCX7353 on the pharmacokinetics of rosuvastatin. Cohort 3 will evaluate the effect of a single dose of cyclosporine on the pharmacokinetics of BCX7353. Cohorts may be dosed in parallel or in any order.
