This is an open-label, single dose study in healthy male subjects.

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

A baseline (predose) fecal sample and a baseline (predose) urine sample will be obtained at the clinic prior to dosing on Day 1.

On Day 1, subjects will begin the Treatment Phase. Subjects will be released from the clinic after at least 10 days since dosing and as soon as the following conditions are met:

  • greater than 90% of the administered radioactivity has been recovered, and
  • less than 1% of the administered radioactive dose is recovered in two consecutive 24-hour samples each of urine and feces

Study Type

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

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

Description

Inclusion Criteria

Subjects must meet criteria to be included in this study, including but not limited to the following:

  1. Healthy male 18 - 55 years, inclusive, at the time of informed consent
  2. Body mass index (BMI) of 18 to 32 kg/m2 at Screening
  3. Subjects must have had a successful vasectomy (confirmed azoospermia) or they and their female partners not be of childbearing potential or must be practicing highly effective contraception throughout the study period and for 30 days after study drug discontinuation. Sperm donation is not allowed during the study period and for 30 days after study drug discontinuation.
  4. Provide written informed consent
  5. Willing and able to comply with all aspects of the protocol

Exclusion Criteria

Subjects who meet any of the following criteria will be excluded from this study:

  1. Have participated in a 14C-research study within the 6 months prior to Day -2. The total exposure from this and any previous study must be within the recommended levels considered safe.
  2. Exposure to clinically significant radiation within 12 months prior to Day -2.
  3. Any laboratory abnormalities considered clinically significant by the investigator, which may require further investigations or treatment
  4. Clinically significant illness which required medical treatment within 8 weeks or a clinically significant infection within 4 weeks of dosing
  5. Any history of gastrointestinal surgery (e.g., hepatectomy, nephrotomy, digestive organ resection) that may affect PK profiles of study drugs
  6. Hypersensitivity to the study drugs or any of their excipients
  7. Known to be human immunodeficiency virus (HIV) positive

Restrictions will apply on prior and concomitant medications, food and beverages

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
Measure Description
Time Frame
Pharmacokinetics: Elimination of E2609: urine/feces concentration
Time Frame: Predose and every 24 hours postdose up to 28 days
Total radioactivity will be analyzed in urine and feces predose and up to 28 days postdose.
Predose and every 24 hours postdose up to 28 days
Pharmacokinetics: Plasma concentration of E2609/metabolite
Time Frame: Predose andup to 648 hours postdose
Total radioactivity will be analyzed in whole blood, plasma, and red blood cells.
Predose andup to 648 hours postdose

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
Measure Description
Time Frame
Pharmacokinetics: Metabolic profile of E2609: plasma/urine/feces concentration
Time Frame: Predose andup to 648 hours postdose
Metabolite profiling in plasma, urine, and feces will be performed by liquid chromatography with radiodetection (radio-high performance liquid chromatography [HPLC]) methods. A scintillation counter and/or AMS will be used to detect radioactivity. If needed, plasma and feces samples will be treated with cysteine and/or other reagents before radio-HPLC analyses.
Predose andup to 648 hours postdose

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
