CPH-82 (Reumacon) versus auranofin (Ridaura): a 36-week study of their respective onset of action rates in RA

The onset of action rate of CPH-82 (Reumacon), was compared with that of auranofin (AUR; Ridaura) in a 36-week randomised, double-blind, multicentre study of 60 patients with rheumatoid arthritis (RA). As compared with respective baseline values, the CPH-82 group manifested significant improvement in grip strength, Ritchie's articular index (RAI), pain ratings, and HAQ (health assessment questionnaire) scores after 8, 12, 24, and 36 weeks of treatment, with the exception of the 24-week HAQ score. The AUR group manifested corresponding improvement in RAI after 8, 12, 24, and 36 weeks. Significant differences in changes from baseline values in favour of the CPH-82 group were found for grip strength at 12 and 24 weeks, RAI score at 8 weeks, VAS score at 8 and 12 weeks, and HAQ score at 8 weeks. The findings suggest CPH-82 to manifest a more rapid onset of action than AUR. The two drugs were similar in tolerance and safety.
