Male subject and their female spouse/partner who are of childbearing potential must be using 2 highly effective forms of birth control (1 of which must be a barrier method) starting at screening and continued throughout the clinical study period, and for 90 days after the final study drug administration. Male subject must not donate sperm starting at screening, throughout the clinical study period, and for 90 days after the final study drug administration.

Exclusion Criteria: Subject has a known or suspected hypersensitivity to ASP7962 or any components of the formulation used. Subject has a history of suicide attempt or suicidal behavior. Any suicidal ideation within the last 3 months. Subject has any of the liver function tests (aspartate aminotransferase [AST], alanine aminotransferase [ALT], alkaline phosphatase, gamma glutamyl transferase, total bilirubin [TBL]) above the upper limit of normal [ULN]. In such a case the assessment may be repeated once [day -1]. Subject has any clinically significant history of allergic conditions. Subject has/had febrile illness or symptomatic, viral, bacterial (including upper respiratory infection), or fungal (non-cutaneous) infection within 1 week prior to admission to the clinical unit on day -1. Subject has a mean pulse rate < 40 or > 90 bpm; mean systolic blood pressure (SBP) > 140 mmHg; mean diastolic blood pressure (DPB) > 90 mmHg (vital sign measurements taken in triplicate after subject has been resting in supine position for 5 minutes; pulse rate will be measured automatically) [day -1]. If the mean pulse rate, mean SBP or mean DBP is out of the range as specified above, 1 additional triplicate measurement may be taken on day -1. Subject has a mean corrected QT interval using Fridericia's formula (QTcF) interval > 430 ms (for male subjects) and > 450 ms (for female subjects) on admission to the clinical unit on day 1. If the mean QTcF exceeds the limits above, 1 additional triplicate ECG can be taken [day -1]. Subject uses any prescribed or non-prescribed drugs (including vitamins, natural and herbal remedies, e.g., St. John's wort) in the 2 weeks prior to study drug administration, except for occasional use of paracetamol (up to 2 g/day). Subject has used nicotine-containing products within 6 months prior to admission to the clinical unit. Subject has a history of drinking more than 21 units of alcohol per week for male subjects or 14 units of alcohol per week for female subjects (1 unit = 10 g pure alcohol = 250 mL of beer [5%] or 35 mL of spirits [35%] or 100 mL of wine [12%]) within 3 months prior to admission to the clinical unit. Subject uses any drugs of abuse within 3 months prior to admission to the clinical unit. Subject uses any inducer of metabolism (e.g., barbiturates, rifampin) in the 3 months prior to admission to the clinical unit. Subject has had a significant blood loss, donated 1 unit (500 mL) of blood or more, or received a transfusion of any blood or blood products within 60 days or donated plasma within 7 days prior to admission to the clinical unit. Subject has a positive serology test for hepatitis B surface antigen, hepatitis A virus antibodies (immunoglobulin M), hepatitis C virus antibodies, or antibodies to human immunodeficiency virus type 1 (HIV-1) and/or type 2 (HIV-2) at screening. Subject has participated in any clinical study or has been treated with any investigational drugs within 28 days or 5 half-lives, whichever is longer, prior to screening. Subject is an employee of the Astellas Group or Contract Research Organization involved in the clinical study.
