Purpose

The patients received either Pasireotide LAR or Octreotide LAR for one year of treatment. The objective of this study was to compare the proportion of patients with a reduction of mean GH level to <2.5 µg/L and the normalization of IGF-1 to within normal limits (age and sex related) between the two treatment groups (pasireotide LAR and octreotide LAR) at 12 months. Following one year of treatment patients could proceed into the study extension. Patients who did not respond to the treatment they were randomized to (based on month 12 assessment results) were switched to the other treatment arm at month 13.
