Özet

Objectives Many patients with Cushing's disease (CD) require chronic pharmacotherapy to control their hypercortisolism. We evaluated the efficacy and safety of long-acting pasireotide during a long-term extension study in patients with CD. Design Open-label extension to a 12-month Phase III study of long-acting pasireotide in CD (N = 150; NCT01374906). Patients Patients with mean urinary free cortisol (mUFC) <= upper limit of normal (ULN) or receiving clinical benefit at core study end could continue long-acting pasireotide during the extension. Results Eighty-one of 150 (54.0%) enrolled patients entered the extension. Median overall exposure to pasireotide at study end was 23.9 months; 39/81 (48.1%) patients completed the extension (received >= 12 months' treatment during the extension and could transit to a separate pasireotide safety study). mUFC was <= ULN in 42/81 (51.9%), 13/81 (16.0%) and 43/81 (53.1%) patients at extension baseline, month (M) 36 and last assessment. Median mUFC remained within normal limits. Median late-night salivary cortisol was 2.6 x ULN at core baseline and 1.3 x ULN at M36. Clinical improvements were sustained over time. Forty-two (51.9%) patients discontinued during the extension: 25 (30.9%) before M24 and 17 (21.0%) after M24. Hyperglycaemia-related AEs occurred in 39.5% of patients. Mean fasting glucose (FPG) and glycated haemoglobin (HbA(1c)) were stable during the extension, with antidiabetic medication initiated/escalated in some patients. Sixty-six (81.5%) and 71 (88.9%) patients were classified as having diabetes (HbA(1c) >= 6.5%, FPG >= 7.0 mmol/L, antidiabetic medication use, or history of diabetes) at extension baseline and last assessment. Conclusions Long-acting pasireotide provided sustained biochemical and clinical improvements, with no new safety signals emerging, supporting its use as an effective long-term therapy for CD.
