A clinical and biochemical evaluation of Clozic, a novel disease modifying drug in rheumatoid arthritis.
|
| Abstract |
We have compared two dose levels of Clozic, a novel agent with potential anti-rheumatoid activity, to D-penicillamine and aspirin in an observer blind randomised parallel group study of 56 patients with active rheumatoid arthritis. Eight clinical assessments and 26 laboratory assessments were performed on each patient at each visit over a six month period. Results were analysed by conventional methods and also by correlation matrices constructed between clinical and laboratory variables. Patients treated with D-penicillamine (500 mg/day) responded adequately and the control group on aspirin (up to 3.6 g of enteric coated formulation/day) performed well, though the withdrawal rate from this latter group was high, predominantly because of continued disease activity. Patients receiving Clozic (100 mg/day or 300 mg/day) improved more than patients receiving penicillamine, particularly at the higher dose. Comparison of methods of analysis validates the use of correlation matrices both for detecting anti-rheumatoid activity and for determining the optimum dose of a novel compound. This trial illustrates the problems of a study of this nature, with the powerful effect on patients of being enrolled in such a closely monitored investigation. It emphasises the greater value of biochemical changes in following disease changes.
