Introduction: Pasireotide (SOM230) is a multi-receptor targeted somatostatin analogue with high binding affinity for sst1,2,3 and sst5. In a Phase II study of pasireotide in patients with active acromegaly, 27% achieved biochemical control after 1 month of octreotide s.c. followed by 3 months of pasireotide, and pituitary tumor volume decreased by >20% in 39% of patients. Results from the study’s extension phase are presented.<p class="abstex...

Introduction: In a recent 16-week Phase II study in patients with de novo, persistent or recurrent acromegaly, pasireotide effectively controlled GH and/or IGF-I levels in 56% of patients, and reduced tumor volume by >20% in 39% of patients. We present preliminary 6-month results from the ongoing extension phase of this study.Methods: This extension study enrolled patients who achieved biochemical control (GH ≤2.5 μg/l and normalize...

Introduction: In a Phase III trial, pasireotide LAR was significantly superior (P=0.007) to octreotide LAR at providing biochemical control at 12 months in medically naïve acromegaly patients (post-pituitary surgery or de novo). Inadequately controlled patients (GH≥2.5 μg/l and/or IGF-1>ULN) at the end of core study were eligible for switching therapy (crossover extension). Reported here are efficacy results up to 12 months and safety resu...
