Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
436

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.

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Intervention
The intervention group will be enrolled into WeChat platform. Participants will receive health education materials, monitor blood pressure at home and sent the blood pressure record to the platform and consult doctors online via platform.
Other: WeChat platform group
Participants in the intervention group will receive educational messages related to hypertension, such as impact of hypertension on cardiovascular system, lifestyle adjustment and side effects of antihypertensive drugs. Participants will be reminded to take their blood pressure regularly and enter the blood pressure readings into the WeChat platform. If participants enter extremely high or low readings, they will be asked to seek medical help from doctors. Participants can also consult doctors online via WeChat platform by text and voice messages, or voice calls.
No Intervention: Control
Control group will receive usual care and follow up in hospitals and community health centers.

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
Proportion with controlled blood pressure at 12 months (defined by ambulatory blood pressure monitoring )
Time Frame: 12 months
mean 24-hour ambulatory blood pressure monitoring (ABPM) <130/80 mmHg, day time blood pressure <135/85 mmHg, and nocturnal blood pressure <120/70 mmHg
12 months

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
Measure Description
Time Frame
Systolic blood pressure (mmHg) at 12 months
Time Frame: 12 months
Systolic blood pressure (mmHg) at 12 months
