RATIONALE: Rosiglitazone may help pituitary tumor cells become more like normal cells, and to grow and spread more slowly.
PURPOSE: This phase II trial is studying how well rosiglitazone works in treating patients with newly diagnosed ACTH-secreting pituitary tumor (Cushing disease).
|Condition or disease||Intervention/treatment||Phase|
|Cushing's Disease||Drug: rosiglitazone maleate||Phase 2|
- To assess the effect of rosiglitazone on biochemical control in patients with newly diagnosed ACTH-secreting pituitary tumor (Cushing disease).
- To assess the effect of this drug on corticotrophin (CRH)-stimulated pituitary tumor ACTH secretion.
- To assess the overall safety and tolerability of this drug in these patients.
- To assess the overall quality of life of patients treated with this drug.
- Percentage of Reduction in 24-hour Urinary-free Cortisol Levels
OUTLINE: This is a multicenter study.
Patients receive oral rosiglitazone once daily for 7 weeks in the absence of disease progression or unacceptable toxicity.
Blood, urine, and saliva samples are collected periodically for laboratory studies. Inflammatory markers (C-reactive protein, interleukin-6 [IL-6], serum sialic acid, soluble intracellular and vascular adhesion molecules [sICAM-1, and sVCAM-1], and amyloid A) are measured at baseline and at the completion of study treatment; salivary cortisol and 24-hour urinary-free cortisol levels are measured at baseline and weekly during study treatment; dexamethasone suppression tests with serum cortisol and corticotrophin (CRH) stimulation test are performed at baseline and at the completion of study treatment; prolactin, insulin-like growth factor-1 (IGF1), thyroid function, and sex steroid hormones are measured at baseline and at the completion of study treatment; and dynamic pituitary function testing (arginine/growth hormone-releasing hormone [GHRH] testing to measure growth hormone secretion) is performed at baseline.

- Number of Responders [ Time Frame: 7 weeks ]
Definition of Treatment Response
- The primary outcome in Cushing's disease will the % responders, a responder is defined as a patient with 2 consecutive 24h urinary free cortisols within the normal reference range in association with no clinical signs of disease progression.
- Secondary outcomes will include the % reduction in 24h UFC (derived by comparison of the mean of 2 baseline 24h UFC values with mean of the two lowest consecutive 24h UFC values while on study treatment in association with no clinical signs of disease progression).
