SECONDARY outcome

Timeframe: Up to three years.

The mean Investigator's rating of the change in subject's signs and symptoms of Cushing's syndrome from Baseline (Entry into C1073-415) to Endpoint on the Physician's Global Assessment of Disease Severity was ranked on a 9-point scale (9 = much worse, 7 = worse, 5 = no change, 3 = better, 1 = much better). Higher scores indicate more severe illness. Scoring was done at all visits except the 6 Week Follow-up visit; the final visit result (Endpoint) is reported here. The instruction was "Rate the change in the subject's signs and symptoms of Cushing's from Baseline (1 = much better to 9 = much worse)".
