Octreotide in Severe Polycystic Liver Disease

The primary aim of this study is to compare the effect of Octreotide LAR® Depot on the liver volume of patients with severe polycystic liver disease who are not candidates or decline surgical treatments such as liver cyst fenestration, liver resection or liver transplantation compared with placebo. The secondary aims of the study are: (1)Assess the effect of Octreotide LAR® Depot on the total kidney volume and iothalamate clearance in patients with polycystic kidney disease associated with severe polycystic liver disease who are not candidates or decline surgical treatments such as liver cyst fenestration, liver resection or liver transplantation. (2)Evaluate quality of life changes associated with the administration of Octreotide LAR® Depot in these patients. (3)Assess toxicity of Octreotide LAR® Depot in patients with polycystic liver disease (PLD). Note: Subjects who completed this 1 year randomized trial were offered enrollment into an open-label (all subjects received Octreotide) extension trial for an additional two years of treatment.
