|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to compare the blood pressure control (MSSBP/MSDBP < 140/90 mmHg) rates between a once daily regimen of the combination therapy valsartan/HCTZ 160/12.5 mg (with forced titration to 160/25 mg after 14 days and 320/25 mg after 28 days) and the monotherapy of valsartan 160 mg (with forced titration to 320 mg after 14 days) as initial therapy in patients with severe hypertension after 4 weeks of treatment. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this trial are the following: • percentage of patients achieving systolic and diastolic blood pressure control (MSSBP/MSDBP < 140/90 mmHg) after 6 weeks of treatment • percentage of patients achieving diastolic blood pressure control (MSDBP < 90 mmHg) after 4 and 6 weeks of treatment • percentage of patients achieving systolic blood pressure control (MSSBP < 140 mmHg) after 4 and 6 weeks of treatment • change from baseline in MSSBP and MSDBP after 4 and 6 weeks of the study • safety and tolerability of valsartan/HCTZ 160/12.5 mg as initial therapy in patients with severe hypertension

Diabetes with poor glucose control as defined by fasting glycosylated hemoglobin (HbA1c) > 7% at Visit 1. 13. Administration of any agent indicated for the treatment of hypertension after Visit 1, with the permitted exception of those anti-hypertensive medications requiring tapering down commencing at Visit 1. 14. Known or suspected contraindications, including a history of allergy to angiotensin receptor blockers or thiazide diuretics. 15. Any surgical or medical conditions which might significantly alter the absorption, distribution, metabolism, or excretion of any drug including but not limited to any of the following: history of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, bowel resection, gastric bypass, gastric stapling, or gastric banding, currently active or active inflammatory bowel syndrome within 12 months prior to Visit 1, currently active gastritis, ulcers, or gastrointestinal/rectal bleeding, or urinary tract obstruction regarded as clinically meaningful by the investigator. 16.
