A Study to Assess Mass Balance, Pharmacokinetics, Metabolism, and Excretion of Emraclidine in Healthy Adult Male Participants
Status: Recruiting

The primary purpose of this study is to determine the mass balance, routes, and rates of elimination of total radioactivity and characterize the pharmacokinetics (PK) of emraclidine, metabolite CV-0000364, and total radioactivity in plasma and whole blood following a single oral dose of [14C]-emraclidine in healthy adult male participants.

Eligibility:
- EligibilityCriteria: Inclusion Criteria:  Body mass index (BMI) of 18.5 to 35.0 kilograms per square meters (kg/m^2), inclusive, and a total body weight ≥50 kg [110 Pounds (lbs)]. A male participant who is sexually active with a pregnant or a nonpregnant woman of childbearing potential must agree to use a condom during the trial and for 90 days after the dose of investigational medicinal product (IMP). In addition, male participants should not donate sperm for a minimum of 90 days following the dose of IMP. Ability, in the opinion of the investigator, to understand the nature of the trial and comply with protocol requirements, including the prescribed dosage regimens, scheduled visits, laboratory tests, and other trial procedures. Capable of consuming the standard diet. History of a minimum of 1 bowel movement per day.  Exclusion Criteria:  Current or past history of significant cardiovascular, pulmonary, gastrointestinal, renal, hepatic, metabolic, genitourinary, endocrine (including diabetes mellitus, thyroid disorders), malignancy, hematological, immunological, neurological, or psychiatric disease that, in the opinion of the investigator or medical monitor, could compromise either participant safety or the results of the trial.  "Yes" responses for any of the following items on the C-SSRS (within the individual's lifetime):  Suicidal Ideation Item 3 (Active Suicidal Ideation with Any Methods [Not Plan] without Intent to Act) Suicidal Ideation Item 4 (Active Suicidal Ideation with Some Intent to Act, without Specific Plan) Suicidal Ideation Item 5 (Active Suicidal Ideation with Specific Plan and Intent) Any of the Suicidal Behavior items (Actual Attempt, Interrupted Attempt, Aborted Attempt, Preparatory Acts or Behavior)  "Yes" responses for any of the following items on the C-SSRS (within past 12 months):  Suicidal Ideation Item 1 (Wish to be Dead) Suicidal Ideation Item 2 (Non-Specific Active Suicidal Thoughts) Serious risk of suicide in the opinion of the investigator is also exclusionary. Any condition or surgery that could possibly affect drug absorption, including, but not limited to, bowel resections, bariatric weight loss surgery/procedures, gastrectomy, and cholecystectomy. Use of any prescription and over-the-counter medications from 28 days prior to first dose of IMP or likely to require concomitant therapy. Vaccinations or boosters within 28 days of planned dosing or while on trial. Positive result for human immunodeficiency virus (HIV) antibody, hepatitis B surface antigen, hepatitis B total core antibody, or hepatitis C antibody with detectable viral ribonucleic acid (RNA) levels at Screening. Positive drug screen (including cotinine and tetrahydrocannabinol [THC]) or a positive test for alcohol.  Any of the following clinical laboratory test results at the Screening Visit or Check-in (Day -1), which can be confirmed by a single repeat measurement, if deemed necessary:  Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥2× upper limit of normal (ULN). Total bilirubin ≥1.5×ULN. If Gilbert's syndrome is suspected, total bilirubin ≥1.5×ULN is acceptable if the conjugated or direct bilirubin fraction is <20% of total bilirubin. Known allergy or hypersensitivity to the IMP, closely related compounds, or any of their specified ingredients.  NOTE: Other protocol-defined inclusion/exclusion criteria may apply. - HealthyVolunteers: Accepts Healthy Volunteers - Gender: Male - GenderBased: Yes - GenderDescription: U.S. Food and Drug Administration (FDA) recommends that radiation exposure to participants should be kept as low as is reasonably achievable; and since there is no available data to suggest metabolism of the emraclidine is different in women versus men. Hence, female participants are excluded from this study. - MinimumAge: 18 Years - MaximumAge: 55 Years - StdAgeList: Adult
