Topical Compound Tripterygium Wilfordii Hook F for Patients With Active Rheumatoid Arthritis

April 27, 2017 updated by: Quan Jiang, Guang'anmen Hospital of China Academy of Chinese Medical Sciences

A Randomized Controlled Study to Determine the Effects and Safety of Topical Compound Tripterygium Wilfordii Hook F in Patients With Active Rheumatoid Arthritis.

Rheumatoid Arthritis (RA) is an autoimmune disease that results in a chronic inflammatory disorder that may affect many synovial joints, and may cause serious disability. It has been confirmed that Tripterygium wilfordii Hook F has effects of anti-inflammatory, immunosuppressive and cartilage protection. This is a prospective randomized controlled study to evaluated the efficacy and safety of external application with compound Tripterygium wilfordii Hook F in treating of patients with rheumatoid arthritis (RA).

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.

Study Type

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

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders 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: Topical Tripterygium group
Patients were treated with topical compound tripterygium for 1 hour, twice per day. Area dosages were as followed that each 1st to 5th metacarpophalangeal joints (MCPJs), 1st to 5th proximal interphalangeal joints (PIPJs) and wrist was 3 ml, each elbow and ankle was 5 ml, each knee was 10 ml.
Drug: Topical compound tripterygium
Topical compound tripterygium was applied for the pain and swollen joints on non-woven fabric for 1 hour, twice per day.
Placebo Comparator: Topical Placebo group
Patients were treated with topical placebo for 1 hour, twice per day. The dosage was the same as the topical tripterygium group.
Drug: Placebo
The topical placebo recipe composes viscous agent which matches by the sucrose, and the usage and dosage were the same as the topical compound tripterygium group.

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
ACR20 criteria
Time Frame: Week 4
To meet the criteria, a patient must have 20% or greater improvement in both tender and swollen joints (28 tender and 28 swollen joints were assessed) and 20% or greater improvement in 3 or more of the following: the physician's or patient's assessment of global health status, the patient's assessment of pain on a visual analogue scale, the patient's assessment of function using a modified version of the Health Assessment Questionnaire (HAQ), and the ESR or serum C-reactive protein (CRP) level.
Week 4

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
ACR50 criteria
Time Frame: Week 4
To meet the criteria, a patient must have 50% or greater improvement in both tender and swollen joints (28 tender and 28 swollen joints were assessed) and 50% or greater improvement in 3 or more of the following: the physician's or patient's assessment of global health status, the patient's assessment of pain on a visual analogue scale, the patient's assessment of function using a modified version of the Health Assessment Questionnaire (HAQ), and the ESR or serum C-reactive protein (CRP) level.
