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).
OBJECTIVES:
Primary
Secondary
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.
64 studies on the registry are indexed under Pituitary ACTH Hypersecretion; 16 are open to participants now.
This study's enrollment of 2 is below the median of 44 across 40 interventional studies indexed under Pituitary ACTH Hypersecretion.

DISEASE CHARACTERISTICS:
Clinically demonstrable ACTH-secreting pituitary tumor
Biochemically active disease that is not adequately controlled, as demonstrated by the following standard criteria:
Patients with evidence of optic nerve or chiasm compression on post-operative MRI must have a normal visual field evaluation by Goldman perimetry
Hypopituitarism* allowed, as evidenced by any or all of the following:
PATIENT CHARACTERISTICS:
PRIOR CONCURRENT THERAPY:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Corticosteroids (steroids)
