Introduction: Pasireotide (Signifor®) reduced and normalized UFC in patients with Cushing’s disease in a large, randomized Phase III study. This analysis evaluates the effects of pasireotide on the signs and symptoms of Cushing’s disease according to the degree of UFC control.

Methods: Adult patients (n=162) with persistent/recurrent or de novo Cushing’s disease were randomized to pasireotide 600/900 μg sc bid. Dose titration (max: 1200 μg bid) was allowed after month 3: initiation or changes in antihypertensive, antidiabetic and lipid-lowering medications were permitted throughout the study. Changes in the symptoms of Cushing’s disease during pasireotide treatment were evaluated at 6 and 12 months. UFC measurements were conducted at central laboratories. Controlled (C) UFC was defined as UFC≤ULN at month 6, partially controlled (PC) as UFC>ULN but with ≥50% reduction from baseline at month 6, and uncontrolled (UC) as UFC>ULN without a ≥50% reduction from baseline at month 6. All data shown are mean [95% CI] values.

Results: At month 12, an overall decrease in UFC from baseline was observed in patients who were C (–68% [–79, –56]), PC (–64% [–80,–47]) and UC (–20% [–49, 9]) at month 6. Patients with UFC control at month 6 had the greatest change from baseline in systolic (–12 [–18,–6], –4 [–12, 4] and –3 [–8, 3] mmHg in C, PC and UC groups, respectively) and diastolic BP (–7 [–11, –3], –3 [–9, 2], –1 [–5, 3] in C, PC and UC groups, respectively) at 12 months. Improvements in BMI and weight at month 12 were observed in the three UFC response groups; C (–3 [–4, –2] kg/m2 and –8 [–10, –6] kg, respectively), PC (–2 [3, –1] kg/m2 and –4 [–7, –2] kg, respectively) and UC groups (–3 [–3, –2] kg/m2 and –7 [–9, –5] kg, respectively). Similar results were seen for facial rubor and striae. Fasting plasma glucose and HbA1clevels increased from baseline in all patients receiving pasireotide, irrespective of UFC control. The relative impact of concomitant medications on signs and symptoms could not be evaluated.

Conclusions: Treatment with pasireotide was accompanied by improvements in the signs and symptoms of Cushing’s disease, which were maintained for 12 months. While the treatment goal is biochemical control, it is notable that clinical improvements were not restricted to patients who achieved UFC control, suggesting improvements in UFC with pasireotide may be beneficial in improving signs and symptoms in patients with Cushing’s disease.
