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

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: CHM intervention group
Drug: CHM intervention group
Jia Wei Sheng Yu Si Ni Tang (JWSYSNT) powder, 4.5 gm per dose, taken orally 2 times a day, for 8 weeks
Other: Control group
Participants who do not receive the active CHM treatment during the study's initial phase (8 weeks) but are offered it after the trial ends.
Other: No CHM treatment
The waitlist control group received no JWSYSNT treatments and received no other intervention for 8 weeks after randomization.

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
Total intradialytic hypotension (IDH) epidose
Time Frame: week 1 to 8
IDH episode was record on every dialysis session, account for 24 dialysis sessions. ( IDH was defined as a nadir SBP of < 90 mmHg or requirement for clinical intervention).
week 1 to 8

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
Kidney Disease and Quality of Life-36 (KDQOL-36)
Time Frame: week 1 and 8
The Taiwanese version of the. KDQOL-36 questionnaire is reliable and valid for evaluating the quality of life in dialysis patients. It includes 12 items that provide a generic chronic disease core (i.e., the SF-12, a shorter version of the SF-36), as well as 24 additional items (i.e., kidney-disease-targeted items). The 24 additional items focus on particular health-related concerns of individuals with kidney disease (i.e., symptom/problem list, 12 items; effects of kidney disease, 8 items; and burden of disease, 4 items).KDQOL-36 subscale scores ranged from 0 to 100, and lower scores indicated worse self-reported quality of life.
week 1 and 8
Intradialytic blood pressure (BP) measurement
Time Frame: week 1 to 8
Pre-, nadir-, and post-dialysis systolic and diastolic blood pressure in mmHg at each session.
week 1 to 8
Pharmacotherapy
Time Frame: week 1 to 8
Frequent and dose in mg of vasopressor agents at each session
week 1 to 8

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Constitution in Chinese Medicine Questionnaire
Time Frame: week 0
All participants were asked to complete a basic information questionnaire before CHM treatment and an assessment of their TCM constitution. The CCMQ consisted of 60 items (clinical observations, indicators of constitutions, Table 2) categorized into 9 subscales, each measuring one of the 9 different body constitutions, namely, Yang-deficient (7 items), Yin-deficient (8 items), Qi-deficient (8 items), Phlegm-dampness (8 items), Damp-heat (6 items), Stagnant Blood (7 items), Inherited Special (7 items), Stagnant Qi (7 items), and Balanced (8 items). The items were on a 5-point Likert scale, with high scores indicating a higher likelihood of having the given constitution. Usually, a threshold of 30 or higher points on a subscale was used to classify a person as having that body constitution.
