New treatment option for Rheumatoid Arthritis (RA)
Official title Integrated Clinical Study of Traditional Chinese and Western Medicine for Refractory Rheumatoid Arthritis
ClinicalTrials.gov ID: NCT07721142
What this study is testing
What is Kunxian Capsule?
Kunxian Capsule is an investigational medicine, given as an once-weekly pill taken by mouth, being studied as a potential treatment for rheumatoid arthritis (ra).
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- To evaluate the efficacy and safety of Kunxian Capsule combined with Methotrexate and Tofacitinib in the treatment of difficult-to-treat rheumatoid arthritis through a multicenter, randomized, double-blind, placebo-controlled clinical trial, and to identify the therapeutic advantages of integrated Chinese and Western medicine for optimizing the clinical strategy of D2T RA.
- Phase 4: studies an already-approved treatment
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
