A Phase 3 Long-term Study of TAK-536 in Pediatric Patients 6 to Less Than 16 Years With Hypertension


Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Pediatric Hypertension
  • Age: Between 6 - 15 Years
  • Gender: Male or Female

Inclusion Criteria:

  1. In the opinion of the investigator or subinvestigator, the participant's parent or the participant's legal guardian is capable of understanding and complying with protocol requirements.
  2. The participant's parent or the participant's legal guardian is capable of signing and dating a written, informed consent form on behalf of the participant prior to the initiation of any study procedures. Written informed assent is also obtained from the participant as much as possible.
  3. The Japanese participant who has a diagnosis of hypertension. A participant is eligible if he/she is deemed hypertensive according to the Reference Blood Pressure Values of Children by Gender and Age; office sitting diastolic or systolic blood pressure 95 percentile for essential hypertension without concomitant hypertensive organ damage, and 90 percentile for secondary hypertension with concomitant CKD, diabetes mellitus, heart failure or any hypertensive organ damage.

In addition, participants need to meet the following criteria:

  1. If currently treated with any antihypertensive drugs at the start of the Run-in
    Period

Participant has a documented historical diagnosis of hypertension and an office sitting diastolic or systolic blood pressure meeting the above criteria at the end of the Run-in Period (Week 0).

2. If currently untreated with any antihypertensive drugs at the start of the Run-in

Period

Participant who meets the above criteria on 3 separate time points including screening and the end of the Run-in Period (Week 0). In addition, participant with essential hypertension without concomitant hypertensive organ damage still maintains hypertension with non-pharmacotherapy including foods or exercises for at least 3 months within 1 year prior to the start of screening.

4. The participant is male or female and aged 6 to less than 16 years at the time of informed consent.

5. The participant weighs at least 20 kg at screening. 6. The participant is capable of taking the tablets or granules supplied as the study drug.

7. A participant who has undergone kidney transplantation is eligible if he/she underwent the transplantation at least 6 months earlier at screening, and the graft has been functionally stable (estimated glomerular filtration rate [eGFR] 30 mL/min/1.73 m2) for at least 6 months with evidence (eg, Doppler echography, CT scan [computed tomography] or MRI [magnetic resonance imaging]) excluding grafted kidney arterial stenosis. A participant on immunosuppressive therapy with a stable dose at least 30 days prior to screening is eligible.

8. A female participant of childbearing potential who is sexually active with a nonsterilized male partner agrees to use routinely adequate contraception from signing of informed consent through 1 month after the completion of the study, and proves negative in the pregnancy test at screening.

9. The participants judged by the investigator or subinvestigator that he/she can discontinue the therapy with RAS inhibitors for 2 weeks (acceptable range, 1 to 4 weeks) in safe prior to the Treatment Period.

Exclusion Criteria:

  1. The participant has received any investigational compound within 30 days prior to screening or is participating in another clinical study or a post-marketing clinical study.

Note: This does not apply to participants participating in observational studies without interventional or invasive therapy.

2. The participant previously received therapy with azilsartan. Note: This does not apply to participants participating in single dose pharmacokinetic studies of TAK-536.

3. The participant has poorly controlled hypertension indicated by an office sitting systolic blood pressure higher by at least 15 mmHg and/or an office sitting diastolic blood pressure higher by at least 10 mmHg than the 99 percentiles of the Reference Blood Pressure Values of Children by Gender and Age.

4. The participant has a diagnosis of malignant or accelerated hypertension.

5. The participant was noncompliant (< 70% or > 130%) with the study drug during the Run-in Period.

6. The participant has severe renal dysfunction (eGFR < 30 mL/min/1.73 m2), is receiving dialysis, has a renovascular disease affecting one or both kidneys, severe nephrotic syndrome not in remission, or a serum albumin level < 2.5 g/dL.

7. The participant has a history of, or the signs/symptoms of serious cardiovascular, hepatobiliary, gastrointestinal, endocrine (eg, hyperthyroidism, Cushing's syndrome), hematological, immunological, urinogenital, psychiatric disease, cancer, or any other disease that adversely affects participant's health, or, in the opinion of the investigator or subinvestigator, potentially confounds the study results.

8. The participant has hemodynamically significant left ventricular outflow obstruction due to aortic stenosis or aortic valvular disease, or is scheduled to undergo a medical procedure affecting blood pressure during the study (eg, correction of arterial anomaly).

9. The participant has a history of or concurrent clinically significant abnormality of 12-lead ECG that, in the opinion of the investigator or subinvestigator, disqualifies the participant for participation in the study.

10. The participant has poorly controlled diabetes mellitus indicated by HbA1c > 9.0% at screening.

11. The participant has an alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level 2.5 the upper limit of normal (ULN), or a total bilirubin level 1.5 ULN at screening, severely impaired hepatic function, any active liver disease (regardless of the cause), or jaundice.

12. The participant has hyperkalemia exceeding ULN at screening.

13. The participant has a history of hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) infection at screening.

14. The participant has a known hypersensitivity or allergy to any ARBs.

15. The participant needs treatment with any of the excluded medication.

16. If female, the participant is pregnant or lactating or intending to become pregnant before, during, or within 1 month after the completion of this study.
