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

Potential subjects will be screened to assess their eligibility to enter the study within 28 days prior to the dose administration. Subjects will be admitted into the study site on Day -1 and be confined to the study site until at least Day 8 (168 hours post dose). On Day 1, subjects will receive a single oral dose of [14C]-CYC065. Subjects will be discharged if the following discharge criteria are met: plasma radioactivity levels below the limit of quantitation for 2 consecutive collections, ≥90% mass balance recovery, and ≤1% of the total radioactive dose is recovered in combined excreta (urine and feces) in 2 consecutive 24-hour periods. If discharge criteria are not met by Day 8, subjects will remain in the study site until all discharge criteria are met up to a maximum of Day 15.

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

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Males, of any race, between 18 and 55 years of age, inclusive.
  2. Body mass index (BMI) between 18.0 and 32.0 kg/m2, inclusive, with a total body weight ≥50 kg.
  3. In good health, determined by no clinically significant findings from medical history, 12-lead electrocardiogram (ECG), vital signs measurements, and clinical laboratory evaluations at screening and check-in and from the physical examination at check-in, as assessed by the investigator (or designee).
  4. Males will agree to use contraception.
  5. Able to comprehend and willing to sign an ICF and to abide by the study restrictions.
  6. History of a minimum of 1 bowel movement per day.

Exclusion Criteria

  1. Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator (or designee).
  2. History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the investigator (or designee).
  3. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed).
  4. Confirmed (eg, 2 consecutive measurements) systolic blood pressure >140 mmHg or <90 mmHg, diastolic blood pressure >90 mmHg or <50 mmHg, and pulse rate >100 beats per minute or <40 beats per minute.
  5. Positive hepatitis panel and/or positive human immunodeficiency virus test.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Up to 8 subjects will be enrolled and studied as a single group
The purpose of this study is to determine the absorption, metabolism, and excretion (AME) of [14C]CYC065 and to characterize and determine, where possible, the metabolites present in plasma, urine, and feces in healthy male subjects following a single oral administration.
