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

The investigators will aim to enroll 200 female adult patients (aged between 20 and 40 years) of all ethnicities/races, who have been referred to the Fourth Affiliated Hospital of Guangxi Medical University for breast cancer related unilateral lymphedema. The investigators will be using a standardized data collection form in this study, where standard of care will be practiced and the patients are not placed at additional risk from participating in this study. However, as the investigators are collecting data prospectively, all participants will sign consent.

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 to 40 years (Adult)

Accepts Healthy Volunteers

No

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: Wuling San

This is a double-blinded, randomized placebo-controlled, multi-center clinic trial, using before and after treatment measurements.

A total of 200 clinical diagnosed BCRL participants with affected arm circumference 10-40% larger than unaffected arm, are randomly allocated to two groups: the Wuling San group or the placebo group, where the intervention group administers Wuling San, at a dosage of 1g/kg, twice a day for six weeks. The primary outcome measurement will be the percentage of limb volume changes measured by perometry.
Drug: Wuling San
Patients will be administrated with Wuling San at a dosage of 1g/kg twice a day after randomisation.
Placebo Comparator: placebo
A total of 200 clinical diagnosed BCRL participants with affected arm circumference 10-40% larger than unaffected arm, are randomly allocated to two groups: the Wuling San group or the placebo group, where the placebo group administers a placebo powder, at a dosage of 1g/kg, twice a day for six weeks. The primary outcome measurement will be the percentage of limb volume changes measured by perometry.
Drug: placebo
Patients will be administrated with placebo powder at a dosage of 1g/kg twice a day after randomisation.

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
volume changes % measured by perometry
Time Frame: baseline and 2 months

Volume changes in the arm after the therapy will be calculated using the methods established by Anderson et al (2000). Briefly, the difference in volume measurements between the normal and lymphedematous arms at baseline will be compared to the volume differential after drug treatment (i.e volume excess) using the following formula:

Change in absolute edema=(Vo-Vc)B-(Vo-Vc)3 months/(Vo-Vc)B

Change in ln ratio=ln (Vo/Vc)B-ln (Vo/Vc)3 months.

Vo is the volume of the lymphedema arm. Vc is the volume of the contralateral arm.

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.
