Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy male and female subjects between 18 and 55 years old (inclusive);
• BMI inclusive of 18-32 kg/m2 at screening and a minimum weight of 50 kg;
• Willingness to remain in the hospital research unit for the duration of the inpatient period.

You may not qualify if:

• Clinically significant abnormality within 2 years of Screening that in the Investigator's opinion may place the subject at risk or interfere with study outcome variables; this includes, but is not limited to, history of or current cardiac, hepatic, renal, neurologic, gastrointestinal, pulmonary, endocrinologic, hematologic, or immunologic disease or history of malignancy;
• 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;
• Any condition which would preclude MRI or PET/CT examination (eg, implanted metal, claustrophobia, unable to fit in PET/CT or MRI scanners);
• Contraindications based on any previous MRI or the study MRI performed prior to the baseline PET/CT scan.

Model Details: This study includes up to 3 sequential parts (Parts A, B and C). In Part A, subjects will be assigned to 1 of 3 cohorts, will receive a single dose of ITI-1284, and undergo one postdose PET/CT scan starting at 1 hour postdose. In Part B, subjects will be assigned to 1 of 2 cohorts, will receive a single dose of ITI-1284, and undergo one postdose PET/CT scan starting at 1 hour postdose. In Part C, subjects will receive a single dose of ITI-1284 and undergo one postdose PET/CT scans starting at approximately 24 hours postdose.
