January 24, 2020 updated by: BioCryst Pharmaceuticals

A Phase 1, Single-Dose, 3-Period Crossover Study to Evaluate the Relative Bioavailability of Two BCX7353 Capsule Formulations and to Evaluate the Effect of Food on BCX7353 Pharmacokinetics in Healthy Subjects

This is an open-label, randomized study to investigate the relative bioavailability of two formulations of BCX7353 and to determine if there is a food effect

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

In this study, 24 healthy subjects will be randomized to receive a single dose of two formulations of BCX7353 and one of the formulations administered with a high-fat meal. A 14-day washout period will separate each dose.

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.
Outcome Measure
Time Frame
Geometric least-squares mean ratio for Cmax for test (blend in capsule) versus reference formulation (API in capsule)
Time Frame: plasma pharmacokinetic parameters are based on blood sampling over a 72 hour period
plasma pharmacokinetic parameters are based on blood sampling over a 72 hour period
Geometric least-squares mean ratio for AUClast for test (blend in capsule) versus reference formulation (API in capsule)
Time Frame: plasma pharmacokinetic parameters are based on blood sampling over a 72 hour period

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.
