Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Lodotra<br>After the 4 week run-in period with immediate release prednisone (Cortancyl), patients were switched to the identical dose of modified release prednisone tablets (Lodotra). Study medication for the Lodotra treatment period consisted of Lodotra in 2 dose strengths (5 mg and 1 mg prednisone per tablet). Patients were to take their tablets with or after the evening meal (at 10 pm +/- 30 minutes) for 4 weeks. | Drug: Lodotra<br>* Administered with food at approximately 10 pm during the 4 week treatment period; patients received the identical dose of Lodotra as received of IR prednisone during the run-in period.<br>* Other names: modified release tablet formulation of prednisone;|
| Active Comparator: Cortancyl<br>During the 4 week run-in period, patients remained on their respective pre-study dose of prednisone or equivalent. However, patients were standardized to 5 mg and 1 mg tablets of immediate release prednisone (Cortancyl). Patients were to take their tablets with or after the morning meal (at 8am +/- 30 minutes) for 4 weeks. | Drug: Cortancyl<br>* Administered in the morning with food during the 4 week run-in period; patients remained on their respective pre-study dose of prednisone or equivalent standardized to 5 mg and 1 mg tablets of immediate release (IR) prednisone (Cortancyl).<br>* Other names: immediate release prednisone tablets;|
