Open Label Dose Escalation Study of Sandostatin LAR Therapy
Acromegaly is a rare disorder due in almost all cases to a GH secreting tumor of the pituitary gland. The initial treatment is typically surgical removal of the tumor, but after this many patients have residual disease requiring additional therapy. For most patients this therapy is medical with a somatostatin analog. In addition to biochemical control, important and often overlooked goals of acromegaly care are to treat its associated co-morbidities in particular insulin resistance and diabetes mellitus, hypertension and cardiovascular (CV) disease. Changes in body composition in acromegaly may be integral to the development of insulin resistance and increased CV risk. Therefore, this study sought to examine the effect of lowering of serum IGF-I levels into the current more stringent normal range during treatment with octreotide LAR on metabolic parameters, body composition and cardiovascular risk profile in patients with acromegaly.
