Abstract

BACKGROUND: SKI306X, which consists of biologically active ingredients from Clematis mandsburica, Tricbosantbes kirilowii, and Prunella vulgaris, was developed and tested in preclinical trials in Korea. Those studies found that SKI306X was associated with an anti-inflammatory and analgesic effect, and that it can delay the destruction of cartilage in rheumatoid arthritis (RA).

OBJECTIVE: The aim of this study was to compare the pain relief and tolerability of SKI306X and celecoxib in patients with RA.

METHODS: This study was a 6-week, multicenter, randomized, double-blind, double-dummy, Phase III, noninferiority clinical trial. Eligible patients were aged 18 to 80 years, had a history of RA with a disease duration of > or =3 months, and were functional American College of Rheumatology (ACR) class I, II, or III before entry. After a washout period of 2 weeks, patients were randomized to SKI306X 200 mg TID or celecoxib 200 mg BID for 6 weeks. The primary end point was a change in patient assessment of pain intensity using a visual analog scale (VAS). The secondary end points were a 20% improvement in response rate as defined by the ACR (ACR20) and the frequency of rescue medication use. Results after 3 and 6 weeks of treatment were compared with baseline and between treatment groups, and all patients were assessed for adverse events (AEs), clinical laboratory data, and vital signs. AEs were identified based on spontaneous reports by patients during interviews conducted by the…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 92 participants or records.
