A Drug-Drug Interaction Study to Evaluate Drug Transporter Interactions

October 24, 2017 updated by: BioCryst Pharmaceuticals

A Phase 1 Study to Evaluate the Effect of BCX7353 on the Single Dose Pharmacokinetics of the P-gp Substrate Digoxin and the BCRP Substrate Rosuvastatin and the Effect of the P-gp Inhibitor Cyclosporine on the Single Dose Pharmacokinetics of BCX7353

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
