Study to Determine How BCX4161 is Metabolized and Eliminated by the Body

October 27, 2014 updated by: BioCryst Pharmaceuticals

A Phase 1 Study to Evaluate the Absorption, Metabolism and Excretion of BCX4161 Following Administration of a Single, Oral Dose of [14C]-Radiolabelled BCX4161 to Healthy Male Subjects

The purpose of the study is to assess the extent that radioactive dose of BCX4161 taken by mouth ends up in the urine, feces and expired air. If there are metabolites of BCX4161 made by the body, the chemical composition of these metabolites and their profile over time in blood and urine will be determined.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

Ages Eligible for Study

26 years to 61 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Mass balance of BCX4161 after a single oral dose of [14C] BCX4161 based upon radioactivity excreted in urine, expired air and feces
Time Frame: Determined from samples drawn up to 14 days post-dose
Determined from samples drawn up to 14 days post-dose

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.
Outcome Measure
Time Frame
Chemical structure elucidation of major metabolites of [14C] BCX4161 in urine, plasma, feces, urine
Time Frame: Determined from samples drawn up to 4 days post-dose
Determined from samples drawn up to 4 days post-dose

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
