Study Endpoints

Primary Endpoints

Relative Change From Baseline in Duration of Morning Stiffness at Week 12
Baseline, Week 12

Duration of morning stiffness was defined as the time elapsed (in minutes) between the time of usual awakening (even if not in the morning) and the time the participant was able to resume normal activities without stiffness. Relative (percent) change = (\[value at Week 12 minus value at Baseline\] divided by \[value at baseline\]) multiplied by 100.

Secondary Endpoints

Relative Change From Baseline in 28-Joint Disease Activity Score (DAS28) at Week 12
Baseline, Week 12
Percentage of Participants With Recurrence of Joint Stiffness at Week 12
Week 12
Relative Change From Baseline in Pain Intensity at Week 12

What clinical trials is IR Prednisone in?

IR Prednisone has one completed Phase 3 clinical trial, identified as NCT00146640. This randomized, double-blind, active-controlled study compared a modified-release formulation of prednisone to standard immediate-release prednisone in 288 participants with rheumatoid arthritis. The trial was conducted in Germany and Poland.

Is IR Prednisone the same as modified-release prednisone?

No, IR Prednisone is the immediate-release formulation of prednisone, while the clinical trial NCT00146640 compared it to a modified-release formulation. The study was designed to evaluate the modified-release tablet against the standard immediate-release version in participants with rheumatoid arthritis.
