Post-marketing Re-evaluation of WangBi Granules for Rheumatoid Arthritis

January 17, 2025 updated by: Zihan Wang, China-Japan Friendship Hospital

Reevaluation of Original Research Results of Integrated Traditional Chinese and Western Medicine and Transformation of Hospital Preparations: Post-marketing Re-evaluation of WangBi Granules for Rheumatoid Arthritis

The group used a randomized controlled trial to conduct a post-marketing re-evaluation study of Wangbi granules. The study was conducted to observe the degree of clinical remission in rheumatoid arthritis patients with low disease activity after standard methotrexate and tofacitinib citrate treatment, using a combination of Chinese and Western medicine treatment with Wangbi granules. The study aims to provide evidence-based medical evidence to improve the clinical efficacy of rheumatoid arthritis, enhance the depth of remission, and improve the diagnosis and treatment of rheumatoid arthritis.

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.

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.

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
DAS28
Time Frame: 12 weeks
Disease mobility score for 28 joints, higher scores indicate higher disease activity
12 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
Fatigue Scale-14

assessing the patient's fatigue level, the higher the score, the more severe the fatigue
12 weeks
visual analogue scale
