Brief Summary:
Nelson's syndrome, an expanding pituitary tumour, occurs in up to 30% of adults after bilateral adrenalectomy for Cushing's disease, for which no medical treatment exists. Plasma Adrenocorticotrophic hormone (ACTH) levels in these patients remain high, they are characteristically deeply pigmented, and may experience neurological effects as a consequence of the tumour. It is not known whether the tumour growth is due to the lack of cortisol feedback after adrenalectomy or whether the pituitary cells were preprogrammed to develop into a tumour.
There is a real need for an effective medical management for Nelson's syndrome. This is especially true given the increasing data on the somewhat disappointing longterm outcome of transsphenoidal surgery, and the increasing use of aparoscopic bilateral adrenalectomy for failures of pituitary surgery or even as primary therapy for Cushing's disease. Therefore, it is likely that there will be increasing numbers of patients attending endocrine centres worldwide with Nelson's syndrome following bilateral adrenalectomy as part of their management for Cushing's disease. In view of this it is important to investigate all potential avenues for the treatment of Nelson's syndrome and translate any benefits to patients.
This study, designed and initiated by the investigators, will assess if pasireotide reduces ACTH levels and tumour volume in patients with Nelson's syndrome. Patients will be recruited for a period of 32 weeks and receive 4 weeks of pasireotide twice daily and then 24 weeks of pasireotide long acting release therapy every 4 weeks. Over the 32 week protocol patients will make 12 visits for serial ACTH blood measurements and have 2 MRI scans to assess tumour volume.
