Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion criteria:

  • Participant will have reached the legal age by the time of entrance into the run-in period.
  • Participant has no active medical problem, other than essential hypertension,

which might of itself or by this treatment significantly affect the Participant's blood pressure.

- Participants diagnosed with mild to moderate essential hypertension or

hypertension accompanying with established cardiovascular (CV) and renal diseases who are receiving antihypertensive regimen (exclude diuretic), yet not attaining to treatment goal*.

* Note: For essential hypertension, the goal is to reduce the blood pressure to less than 140/90. For hypertension with established CV and renal diseases, the BP goal is < 130/80. (According to 2007 European Society of Hypertension (ESH) - European Society of Cardiology (ESC) guideline)

  • Participant is either receiving antihypertensive therapy or no treatment.
  • Participants with stable diabetes mellitus may enter the study.

Exclusion criteria:

  • Pregnant or lactating females.
  • Secondary hypertension of any etiology (such as unilateral or bilateral renal

disease, renal artery stenosis, coarctation of the aorta, pheochromocytoma).

  • History of malignant hypertension.
  • Sitting systolic blood pressure >210 mmHg at Visit 1 (Day 0).
  • Participants with unresolved cerebrovascular accident or transient ischemic attack in the acute stage at visit 1.
  • A clinically confirmed myocardial infarction within the recent 3 months.
  • Angina pectoris.
  • Clinically important cardiac arrhythmia.
  • History of unexplained syncope within the prior 2 years, or a known syncopal

disorder.

- Presence of hemodynamically significant obstructive valvular disease of

cardiomyopathy.

  • Percutaneous coronary angioplasty or coronary artery bypass surgery within the prior 3 months of visit 1.
  • Participant with a single functioning kidney.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Change From Baseline in Trough Sitting Diastolic Blood Pressure (SiDBP) at Week 12
Time Frame: At Baseline and Week 12
Participants with SiDBP of 95-115 mmHg at the end of Baseline had SiDBP measured after 12 weeks of treatment.
At Baseline and Week 12

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
