About this study
Official title: A Multicenter Prospective Study of Iguratimod in Combination With Tofacitinib in Patients With Rheumatoid Arthritis With Poor Response to Conventional or Biological DMARDs
Rheumatoid arthritis (RA) is a common chronic inflammatory autoimmune disease characterized by synovitis, which can cause joint pain, deformity, and extra-articular symptoms, seriously affecting the quality of life and lifespan of patients. Currently, the treatment of RA adopts a target attainment strategy, aiming to control the disease and reduce the disability rate. Although traditional disease-modifying antirheumatic drugs (DMARDs) can alleviate symptoms, they have slow onset, many side effects, and cannot completely stop the disease progression. Among biological DMARDs (bDMARDs), tumor necrosis factor-α (TNF-α) inhibitors have better effects, but some patients have poor responses and their conditions are not effectively controlled, thus new treatment options are urgently needed. This study aims to evaluate the efficacy and safety of the combination of iguratimod and tofacitinib in the treatment of RA patients with poor responses to traditional or biological DMARDs, providing evidence-based support for clinical treatment.
Read the detailed description
This protocol is a multicenter, prospective study on the treatment of RA patients with poor response to conventional or biological DMARDs using a combination of iguratimod and tofacitinib. The study will be conducted simultaneously at 8 research centers, and each center will strictly follow the unified research protocol and standard operating procedures.
Researchers are not allowed to interfere with the treatment of patients. The treatment and follow-up arrangements are determined by the prescribing doctor based on the actual clinical situation. Enrolled patients receive standard-dose treatment with aramodine combined with tofacitinib. The recommended dose of iguratimod is 25mg twice a day, and the recommended dose of tofacitinib is 5mg twice a day. During the treatment period, other background treatment drugs (decided by the prescribing doctor) are allowed, but other anti-rheumatic drugs that may affect the research results are not allowed, in order to simulate the real clinical diagnosis and treatment environment to the greatest extent and ensure the extrapolation of the research results.
The observation period was from the time of patient enrollment to 24 weeks after the end of treatment. For patients who experienced serious adverse events (SAEs), follow-up was conducted until the outcome was clear or the study was terminated. During the study, the patients' disease conditions, adverse drug reactions, and other situations were closely monitored. At each follow-up visit, the researchers would record the patients' symptoms and signs in detail, conduct relevant laboratory tests and necessary imaging examinations, and comprehensively assess the patients' disease status and treatment effects.
This study adopts a parallel controlled design, setting up a combined treatment group without an additional control group. The focus is on evaluating the efficacy and safety of the combined treatment plan in the target patient population. Through multi-center collaboration, data from patients with different characteristics in various regions will be extensively collected to enhance the representativeness and reliability of the research results. Meanwhile, to ensure the quality of the research data, a complete data management and quality control system will be established. Regular audits and evaluations of the data from each center will be conducted to promptly identify and correct any issues in the data.

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jie Chang (+8613705790575, changjie7311@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ACR20 (%) (time frame: 12 and 24 weeks of treatment). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Apr 2025; AzTrials last refreshed its copy on 7 Nov 2026.
