Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To find out if overnight variations in blood levels of chemicals (called cytokines) which cause or reduce inflammation in rheumatoid arthritis are changed by taking a new timed release tablet that provides a dose of the steroid prednisone in the middle of the night.;Secondary Objective: To find out if blood cytokine levels are related to the hormones of the hypothalamic-pituitary-adrenal axis, which is the body's natural system for making and controlling steroid production.;Primary end point(s): Changes in the pattern of cytokines and HPA axis constituents before and after patients have been taking nightime prednisone. The principle measures will be Interleukine-6 and cortisol. The main analytical outcome will be the relative size and timing of the rise in levels of these measures between 2am and 9am. | — |
