Effect of Pasireotide LAR on Gonadotroph Adenomas: A Pilot Study

Gonadotroph adenomas are the most common pituitary macroadenomas. Currently no medical
treatment as been found that decreases the size of these adenomas, so surgery is the only
treatment. The reason to think that pasireotide might affect gonadotroph adenomas is that
pasireotide binds avidly to somatostatin subtype 5 receptors, and gonadotroph adenomas
express these receptors. For this study, three subjects who have gonadotroph adenomas, as
judged by a macroadenoma of the pituitary and elevated serum FSH concentration, will be
treated with a long-acting form of pasireotide once a month for one year. The effect of
pasireotide on the size of the adenoma will be determined by MRI, and FSH secretion will be
judged by the serum concentration.
