Patients will be fasted for at least 10 hours before TR-012001 administration and 4 hours after administration. In group C, the oral drug will be administered as a reference. Alternatively, TR-012001 will be administered with or without a pretreatment of an enzyme inhibitor. Patients should fast for at least 10 hours before the administration of oral drug and TR-012001, and fast for 4 hours after the administration.

Outcome(s)

Primary Outcome

Safety evaluation (1)General physical examination (subjective symptoms, other findings), vital signs (temperature, blood pressure, pulse rate), laboratory tests (hematology, blood biochemistry, urinalysis), Columbia Suicide Severity Rating Scale (C-SSRS) (2)Otolaryngological (nasal cavity scrutiny) findings: evaluation of subjective symptoms (nasal cavity discomfort, burning, itching, pain, nasal obstruction, abnormal taste, nasal discharge, sneezing); evaluation of other findings by the otolaryngologist (nasal cavity ulceration, redness, edema, rhinorrhea, bleeding) (3)Adverse events (type, severity, seriousness, date and time of start, duration, outcome, causal relationship with the study drug, number of cases or incidence rate)

(7)Those with a fever (37.5 degree Celsius or higher). (8)Patients with hemoglobin level less than 13.0 g/dL at screening. (9)Others who have abnormal findings in blood or urine tests and who are judged by the investigator to be unsuitable as subjects for this study. (10)Those who have abnormalities in the electrocardiogram at the time of screening and who are judged by the investigator to be unsuitable as subjects for this study.
