A Phase 3 Pharmacokinetic Study of TAK-536 (Azilsartan) in Pediatric Patients 6 to Less Than 16 Years With Hypertension

Exclusion Criteria

• •1. The participant received an investigational drug within 30 days prior to the start of the observation period or is currently participating in another clinical study or post-marketing study.
• •Note: This does not apply to participants participating in observational studies without interventional or invasive therapy.
• •2. The participant is determined to have poorly controlled hypertension (as a general guideline, when clinical sitting blood pressure is measured, SBP is to be at least 15 mmHg higher and/or DBP is to be at least 10 mmHg higher than the 99th percentile in the Age- and Gender-Based Blood Pressure Reference for Children).
• •3. The participant is diagnosed with malignant hypertension or rapidly progressive hypertension.
• •4. The participant has severe renal dysfunction (eGFR \<30 mL/min/1.73 m\^2), dialysis treatment, renovascular disease affecting both kidneys or a solitary kidney, severe nephrotic syndrome not in remission, or serum albumin \<2.5 g/dL.
• •5. The participant has a history or clinical manifestations of serious cardiovascular, hepatobiliary, gastrointestinal, endocrine (e.g., hyperthyroidism and Cushing's syndrome), hematologic, immunologic, genitourinary, or psychiatric disease; cancer; and/or any conditions that would interfere with the health status of the participant through study participation or would jeopardize study integrity in the opinion of the investigator or subinvestigator.
• •6. The participant has left ventricular outflow tract obstruction affecting hemodynamics due to aortic stenosis, aortic valve disease, or the like or is scheduled to have surgery affecting blood pressure (e.g., repair of arterial anomalies) during the study.
• •7. The participant underwent a surgical procedure with major bleeding within 6 months before the start of the observation period.
• •8. The participant has past or present clinically significant abnormalities on the 12-lead electrocardiogram and is ineligible for the study in the opinion of the investigator or subinvestigator.
• •9. The participant has poorly controlled diabetes mellitus (hemoglobin A1c \[HbA1c\] \>9.0% during the observation period)
• •10. The participant has any of either alanine aminotransferase \[ALT\] or aspartate aminotransferase \[AST\] at least 2.5 times the upper limit of standard value or total bilirubin at least 1.5 times the upper limit of standard value, severe hepatic dysfunction, active liver disease (regardless of etiology), and jaundice during the observation period.
• •11. The participant has hyperkalemia exceeding the upper limit of standard value during the observation period.
• •12. The participant has a history of hepatitis B, hepatitis C, or human immunodeficiency virus infection at the start of the observation period.
• •13. The participant has a history of hypersensitivity or allergy to angiotensin II receptor blockers (ARBs).
• •14. The participant requires treatment with prohibited concomitant drug(s).
• •15. Peripheral venous blood collection from the participant is difficult.
• •16. The participant had a clinically significant acute disease within 30 days from the day before study drug administration.
• •17. If female, the participant is pregnant or lactating, or intending to become pregnant before giving consent, during the study period, or within 1 month after study completion.
