Inclusion Criteria: - body weight (at screening) - Japanese male: =50.0 kg, <80.0 kg - Japanese female: =40.0 kg, <70.0 kg - Caucasian male: =50.0 kg, <100.0 kg - BMI (at screening) - Japanese: =17.6 kg/m2, <26.4 kg/m2 - Caucasians: =18.5 kg/m2, <30.0 kg/m2 - Ethnicity - Japanese: (1) The investigator or subinvestigator will confirm the ethnicity based on appearance (skin color: yellow) and the fact that both parents and four grandparents are of the same race (lineage) based on an interview. (2) The subject has not resided outside Japan for 5 years or longer. - Caucasians: (1) The investigator or subinvestigator will confirm ethnicity based on appearance (skin color: white or brown) and the fact that both parents and four grandparents are of the same race (lineage) based on an interview. (2) The subject has not resided outside the subject's own country for 5 years or longer. - Healthy, as judged by the investigator or subinvestigator based on the results of a medical examination (subjective symptoms and objective findings) and all tests obtained at screening and during the period from hospitalization to immediately before administration. Exclusion Criteria: - Received any investigational drugs in other clinical or post-marketing studies within 120 days before the screening or during the period from the screening to hospitalization (Day -2 [Part 1] or Day -3 [Part 2 and Part 3]) or is scheduled to receive any investigational drugs. - Donated more than or equal to 400 mL of whole blood within 90 days before the screening or during the period from the screening to hospitalization (Day -2 [Part 1] or Day -3 [Part 2 and Part 3]), more than or equal to 200 mL of whole blood within 30 days, or blood components within 14 days before the screening, or is scheduled to donate more than or equal to 400 mL of whole blood or blood components. - Received medications, vitamins including vitamin D, or supplements including calcium, iron, magnesium, or niacin (nicotinic acid or nicotinamide), or is scheduled to receive medications, within 7 days before hospitalization (Day -2 [Part 1] or Day -3 [Part 2 and Part 3]). - A deviation from the normal range of blood pressure, pulse rate, body temperature, or standard 12-lead electrocardiogram (ECG) at screening or Day -1. - Any deviation of the following criteria for laboratory tests at screening or Day -1. The normal ranges specified at the study site or the test/assay organization will be used as the normal ranges in this clinical study. - Hematology: 1. A deviation of +20% from the upper limit or -20% lower limit of the normal range. However, if the WBC is within the normal range, each differential count of leukocytes will be ignored. - Biochemistry: 1. A deviation from the normal range for AST, ALT, Cre, blood glucose, and serum electrolytes (Na, K, Cl, Mg, Ca, and P). 2. A deviation of +20% from the upper limit or -20% lower limit of the normal range for other parameters than the above. However, the lower limit of the normal range will not be established for parameters for which a deviation from the lower limit is not considered clinically significant (AST, ALT, ?-GTP, T-Bil, D-Bil, I-Bil, ALP, LDH, CK, T-Cho, TG, TBA, BUN, Cre, and UA). TBA and iPTH will only be confirmed by laboratory tests at screening. - Urinalysis: 1. A deviation from the normal range of each test parameter (female subjects in Part 2 who are menstruating at screening may be eligible even if urinary blood is positive). - Urinary drug abuse test: 1. A positive result for benzodiazepines, cocaine-based narcotics, analeptic drugs, cannabis, barbituric acid derivatives, morphine-based narcotics, phencyclidines, or tricyclic antidepressants. - Immunological test (at screening only): 1. A positive result for HBs antigen, HBc antibody, HAV antibody (IgM), HCV antibody, HIV antigen/antibody, or syphilis. - Pregnancy test: 1. Female subjects who tested positive for pregnancy. - Failure to meet any criteria for 12-lead ECG for QT assessment at screening (Part 1 and Part 2 only). - Women who are or may be pregnant, lactating mothers, or women who wish to become pregnant during the study period. - Concurrent or history of drug allergies. - Upper gastrointestinal disease (e.g. nausea, vomiting, and stomachache) within 7 days before hospitalization (Day -2 [Part 1] or Day -3 [Part 2 and Part 3]). - Concurrent or previous hepatic disease (e.g. viral hepatitis and drug-induced liver injury). - Concurrent or previous heart disease (e.g. congestive heart failure, ischemic heart disease, and arrhythmia requiring treatment). - Concurrent respiratory disease (e.g. bronchial asthma and chronic bronchitis) or previous serious respiratory disease (except for a history of childhood asthma). - Concurrent gastrointestinal disease (e.g. peptic ulcer and gastroesophageal reflux esophagitis) or previous serious gastrointestinal disease (except for a history of appendicitis). - Previous operation of gut excision (except for a history of appendectomy). - Concurrent or previous renal disease (e.g. acute renal failure, glomerulonephritis, and interstitial nephritis; except for a history of calculus). - Concurrent or previous endocrine disease (e.g. hyperthyroid, hypothyroid, abnormality of growth hormone). - Concurrent or previous cerebrovascular disorder (e.g. cerebral infarction). - Concurrent or previous malignant tumor. - Excessive drinking or smoking habit. [Measure of "excessive"]: - Alcohol: =45 g/day [a large bottle of beer contains 25 g of alcohol, and 1 gou of Japanese sake contains 22 g of alcohol] - Smoking: =20 cigarettes/day - Irregular defecation pattern (less frequent than once a day) (Part 2 and Part 3 only). - Unable to consume or tolerate phosphorus- and calcium-controlled meals during hospitalization. |
