Conditions
Brief summary
This is a single-center, randomized, double-blind, and placebo-controlled trial designed to: 1) demonstrate the degree to which administered andexanet doses can reverse Factor Ten A (FXa)-inhibitor induced anticoagulation; and 2) evaluate the safety and PK/PD of andexanet in healthy Japanese subjects taking direct FXa inhibitors at therapeutic doses.

Eligibility
Inclusion criteria
1. Must be in reasonably good health as determined by the Investigator based on medical history, full physical examination (including blood pressure and pulse rate measurement), 12-lead ECG, and clinical laboratory tests. Subjects with well-controlled, chronic, stable conditions (e.g., controlled hypertension, non-insulin dependent diabetes, osteoarthritis, hypothyroidism) may be enrolled based on the clinical judgment of the Investigator. 2. For all cohorts except Cohort 5, subjects must be of Japanese ethnicity, defined as having four ethnic Japanese grandparents. Subjects may not have lived outside of Japan for more than 10 years. For Cohort 5, subjects must be of Caucasian race. 3. Must be between the ages of 18 and 75 years, inclusive, at the time of signing of the Inform Consent Form (ICF). 4. Agrees to have any dietary or nutritional supplements reviewed by the Investigator and potentially held during the study if advised by the Investigator. Standard multivitamin and mineral supplementation will be permitted. 5. Agrees to comply with the contraception and reproduction restrictions of the study: * Men whose sexual partner is of childbearing potential and/or who are not monogamous must be using two acceptable methods of contraception, at least one of which must be a barrier method (e.g., spermicidal gel plus condom), for the entire duration of the study and for at least 1 month following study-drug administration; and men must refrain from attempting to father a child or donating sperm in the 1 month following the study-drug administration. Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception. * Men who report surgical sterilization (e.g., bilateral vasectomy) must have had the procedure at least 6 months before study drug administration. * Surgical sterilization procedures should be supported with clinical documentation and noted in the Relevant Medical History/Current Medical Conditions section of the case report forms (CRFs). * Women of childbearing potential must be using two medically acceptable methods of contraception, at least one of which must be a barrier method (e.g., non-hormone containing intra-uterine device plus condom, spermicidal gel plus condom, diaphragm plus condom), from the time of Screening and for the duration of the study, through at least 1 month following study drug administration. Note: Oral and topical hormonal contraceptive use, as well as the use of hormone-containing intra-uterine devices, is not permitted due to their increased risk of thromboembolism. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post- ovulation methods) and withdrawal are not acceptable methods of contraception; OR * Postmenopausal women must have had no regular menstrual bleeding for at least 1 year before initial dosing and either be over the age of 60 years or have an elevated plasma follicle-stimulating hormone (FSH) level (i.e., \> 40 milli-international units (mIU)/mL) at Screening; * Women who report surgical sterilization (i.e., hysterectomy, tubal ligation, and/or bilateral oophorectomy) must have had the procedure at least 6 months before study drug administration. Surgical sterilization procedures should be supported with clinical documentation and noted in the Relevant Medical History/Current Medical Conditions section of the CRF; AND All female subjects must have a documented negative pregnancy test result at Screening and on Study Day -1. 6. Systolic blood pressure \< 160 mmHg and diastolic blood pressure \< 90 mmHg at Screening and Day -1. 7. The following laboratory values must be within the normal laboratory reference range within 45 days of Day -1: Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and Activated Clotting Time (ACT); hemoglobin, hematocrit, and platelet count. 8. The following laboratory values must be equal to or below 2 times the upper limit of normal (ULN) range within 45 days of Day -1: Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) and total bilirubin. 9.
