Study Arms:
- Group 1 (ACTH-secreting adenomas) (Type: EXPERIMENTAL): Patients receive 4 mg oral rosiglitazone maleate once daily in week 1 and then 8 mg once daily beginning in week 2 and continuing for up to 6 months in the absence of disease progression or unacceptable toxicity.
- Group 2 (non-secreting macroadenomas) (Type: EXPERIMENTAL): Patients receive 4 mg oral rosiglitazone maleate once daily in week 1 and then 8 mg once daily beginning in week 2 and continuing for up to 12 months in the absence of disease progression or unacceptable toxicity.
