ITI-1284-012 is an open-label, single-dose study to assess the mass balance recovery of radioactivity, and to evaluate the pharmacokinetics, safety and tolerability of ITI-1284 after a single subcutaneous dose of [14C]-ITI-1284 in healthy male subjects.

Inclusion Criteria:

• Healthy male subjects between 30 and 55 years of age (inclusive);
• BMI between18.0 and 32.0 kg/m2, inclusive, at screening, and a minimum body weight of 50 kg at screening;
• Willing to be confined to the clinical research unit for the duration of the inpatient period of the study.

Exclusion Criteria:

• Radiation exposure, including that from the present study, excluding background radiation but including diagnostic X-rays and other medical exposure, exceeding 5 mSev in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker shall participate in the study;
• Subjects who have been enrolled in a 14C-labeled product study in the 10 months prior to dosing with study drug on Day 1;
• Any clinical condition or procedure that may affect the absorption, distribution, biotransformation, or excretion of ITI-1284. Subjects with a history of appendectomy and/or abdominal wall hernia repair are eligible for study participation provided surgery was performed ≥1 year ago;
• Acute diarrhea or constipation in the 7 days before Day 1. If screening occurs > 7 days before Day 1, this criterion will be determined on Day 1;
• Clinically significant abnormal findings in vital sign assessments, supine SBP > 140 mmHg or < 90 mmHg, or supine DBP >90 mmHg or < 50 mmHg or supine pulse rate > 100 bpm or < 45 bpm at Screening;
• History of psychiatric condition that in the Investigator's opinion may be detrimental to participation in the study.
