Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 75

Inclusion Criteria

1. Patients who are eligible and able to participate in the study and whose parent
(s)/guardian(s) consent in writing (written informed consent) to their doing so
after the purpose and nature of the investigation has been clearly explained.
2. Male or female between the ages of 1 to 5 years, at visit 1 with a documented
history of hypertension.
3. Must be able to swallow the liquid formulation of the study medication
4. Must be = 8 kg or = 40 kg
5. Patients, either naïve or treated, must have a documented history of a mean
seated systolic blood pressure (mean of three measurements), equal to or
greater than 95th percentile for age, gender and height (Appendix 3).
6. Patients with uncontrolled blood pressure, receiving background antihypertensive
therapy, may continue on this therapy provided there is no change in dosing
regimen.
7. Patient that has had a previous solid organ transplantation more than 1 year
ago. Patient must be on stable doses of immunosuppressive therapy and
deemed clinically stable by the clinician. Stable doses of immunosuppressive
therapy are defined as no change in frequency or total daily doses of
immunosuppressive therapy for at least 3 months prior to screening. Doses of
immunosuppressive therapy must be maintained throughout Periods 1 and 2 of
the study.
8. Parent(s)/guardian(s) are able to follow verbal and/or written instructions in the
local language.

F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no

Exclusion Criteria

For full list, please refer to protocol.
1. Patients whose mean seated systolic blood pressure (mean of three
measurements), at the baseline visit (Visit # 2) is = 25% higher than the 95th
percentile for age, gender and height see Appendix 3.
2. Physical examination of patient demonstrates abnormalities that would make
this study medically hazardous to the patient.
3. Patients with background ARB therapy.
4. Patients that demonstrate any clinically significant abnormalities or clinically
noteworthy abnormal laboratory values (other than those relating to renal
function), including but not limited to the following:
• AST/SGOT or ALT/SGPT > 3 times the upper limit of the reference range
• Total bilirubin > 2 times the upper limit of the reference range
• Creatinine clearance < 30 mL/min/1.73m² (calculated using Modified Schwartz
formula to estimate glomerular filtration rate [GFR], see section 7.5.5 for
formula, based on the serum creatinine concentration obtained at Visit 1
(Screening).
• WBC count < 3000/mm³
• Platelet count < 100,000/mm³
• Serum potassium > upper limit of the reference range
5. Patients that demonstrate clinically significant ECG abnormalities other than
those associated with left ventricular hypertrophy and AV block controlled with a
pacemaker.
6. Patients that have coarctation of the aorta with a gradient of = 30 mm Hg, or
renal artery stenosis.
7. Patient that has any clinically significant unstable medical condition or chronic
disease that would put the patient at risk of experiencing an adverse event
associated with the expected pharmacodynamic effects of the study medication.
8. Patient that has experienced a significant clinical illness within 10 days prior to
baseline visit.
9. Patient that is known to have tested positive for the hepatitis B surface antigen
or hepatitis C antibody.
10. Patient that is known to have tested seropositive for the human
immunodeficiency virus (HIV) or patient is concomitantly receiving anti-retroviral
therapy.
