Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multicenter, randomized, placebo-controlled, double-blind study. At the end of an initial 2-week washout period, patients fulfilling the inclusion criteria are assigned to three groups, i.e. control group (placebo), low dose Ginseol Kg1 group (100mg), or high dose Ginseol Kg1 (300mg) group. They will intake the study drug for 8 weeks. 24-h ambulatory BP monitoring (ABPM) and pulse wave velocity are measured at the end of the washout period and after 8 weeks of active treatment. At each visit, seated SBP and DBP, heart rate, use of concomitant medication and spontaneously reported adverse events are recorded. Compliance with medication (determined by counting returned tablets) is evaluated at each visit.

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

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
Time Frame
The difference of the changes in office diastolic and systolic BP after 8 weeks' treatment between placebo and Ginseol Kg1 group
Time Frame: baseline and 8 week
baseline and 8 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
The difference of the changes in the mean 24-hour ambulatory systolic and diastolic BP after 8 weeks' treatment between placebo and Ginseol Kg1 group.
