A Specification Clinical Application Research of Tripterygium Wilfordii Treating Rheumatoid Arthritis

November 8, 2017 updated by: Quan Jiang, Guang'anmen Hospital of China Academy of Chinese Medical Sciences

A 24-Week, Multicenter ,Double Blind, Randomized Study to Determine the Effects and Security of Tripterygium Wilfordii Treating Rheumatoid Arthritis and Establish A Prediction Model

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 has effects of anti-inflammatory, immunosuppressive and cartilage protection. This is a multicenter ,double Blind, randomized study to evaluated the efficacy and safety of Tripterygium Wilfordii in treating of patients with rheumatoid arthritis (RA) and establish a prediction model for Tripterygium Wilfordii response of rheumatoid arthritis (RA).

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

45 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
The change in Disease Activity Score (DAS28)
Time Frame: 0 weeks, 4 weeks，12 weeks, 24 weeks,52 weeks
Disease Activity Score for 28-joint counts was based on the erythrocyte sedimentation rate(ESR) (DAS28-4[ESR])
0 weeks, 4 weeks，12 weeks, 24 weeks,52 weeks

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
The proportion of patients achieving ACR20/50/70
Time Frame: 0 weeks, 4 weeks，12 weeks, 24 weeks
ACR20/50/70 is referred to American College of Rheumatology Criteria
0 weeks, 4 weeks，12 weeks, 24 weeks
The change in Health Assessment Questionnaire (HAQ) score
Time Frame: 0 weeks, 4 weeks，12 weeks, 24 weeks,52 weeks
HAQ scores ranges from 0 to 3, with higher scores indicating greater disability
0 weeks, 4 weeks，12 weeks, 24 weeks,52 weeks
The number of adverse events
Time Frame: 24 weeks
The number of adverse events that are related to treatment
24 weeks
The change in Sharp scoring system of van der Heijde(Sharp) score
Time Frame: 0 week,24 weeks,52 weeks
The change in Sharp score from baseline to week 24 and 52.According to the revised Sharp scoring system of van der Heijde, the joint gap score was scored in 30 regions of the hands (score range 0-120 points), and the bone erosion score was conducted in 32 areas (score range 0-160).The higher the score, the more serious the joint destruction.
