E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to assess the efficacy of METYRAPONE in attaining normalization of 24-h urinary free cortisol (UFC) excretion or a ≥50% decrease from baseline using the mean of 2 UFC measurements within 3 months of treatment.
|
Valutare l’efficacia del metopirone (alla dose iniziale di 250 mg t.i.d. con successivi aggiustamenti posologici in tempi prefissati), nell’ottenere una normalizzazione della cortisoluria o una riduzione > 50% rispetto ai valori basali usando la media di 2 determinazioni di cortisolo urinario (CLU) nell’arco di 3 mesi di trattamento |
|
E.2.2 | Secondary objectives of the trial |
• time to response • dose-response relationship • effect of METYRAPONE on levels of serum cortisol, UFC, salivary cortisol, ACTH, 11-deoxicortisol, deoxycorticosterone, total testosterone, androstenedione, DHEA-S in terms of percent variation relative to baseline. • improvement of the clinical signs associated to hypercortisolism (blood pressure, body mass index, waist)
|
• Valutare il tempo alla risposta. • Valutare la risposta in relazione alla dose. • Valutare l’effetto di metopirone sui livelli di cortisolo sierico, CLU, cortisolo salivare, ACTH,11-desossicortisolo, desossicorticosterone, testosterone totale, DHEAS, Androstenedione, in termini di variazione percentuale rispetto al basale. • Valutare il miglioramento dei segni clinici associati a ipercortisolismo: pressione arteriosa, indice di massa corporea, circonferenza vita.

E.3 | Principal inclusion criteria |
Both sexes and age≥ 18 years
- Confirmed diagnosis of ACTH-independent Cushing’s syndrome validated by all the following criteria: • two 24 h urinary collections for UFC at least 1.5 times the upper normal value, within 2 weeks prior to enrollment. • levels of serum ACTH lower than the normal range • CT-confirmed diagnosis of adrenal adenoma (size 2-4 cm, regular shape and margins, homogeneous density <10 HU).

|
• Precedente terapia con metopirone • Terapia con mitotano nei 6 mesi precedenti • Sindrome di Cushing con livelli di ACTH non chiaramente soppressi • Ipercortisolismo secondario a tumore surrenalico sospetto per malignità
