Study to Evaluate the Efficacy and Safety of Sandostatin LAR at High Dose or in Combination Either With GH-receptor Antagonist or Dopamine-agonist in Acromegalic Patients

An Open-label, Two-step, Multicenter European Study to Evaluate the Efficacy and Safety of Sandostatin LAR at High Dose or in Combination Either With GH-receptor Antagonist or Dopamine-agonist in Acromegalic Patients Not Adequately Controlled by Conventional Regimen

This study will assess the efficacy of 8 months treatment of Sandostatin® LAR® High Dose monotherapy or Sandostatin® LAR® High Dose in combination either with growth hormone antagonist or dopamine agonist to control biochemical parameters (GH and insulin-like growth factor I [IGF I]) of acromegalic patients not achieving biochemical normalization at conventional regimen.

Inclusion Criteria:

• Patient with a biochemically documented active acromegaly, not adequately controlled by somatostatin-analogues at conventional regimen as follow : mean 1-hour GH > 2.5 ng/mL and elevated IGF-1 (adjusted for age and gender)

• Patient with reduction of either mean fasting GH at least 50% or IGF-1 at least 25% from any medical pretreatment level
• Patient currently receiving somatostatin-analogues at conventional regimen (maximum registered dose) for at least 6 months before inclusion

Exclusion Criteria:

• Newly diagnosed or previously medically untreated acromegalic patient
• Concomitant treatment with GH-receptor antagonist
• Concomitant treatment with dopamine-agonist
• Symptomatic cholelithiasis or choledocolithiasis
• Liver transaminases (ALT, AST) elevated, but > 3 times upper normal limit (according to local laboratory)
• Previous gamma-knife radiotherapy for treatment of acromegaly
• Compression of the optic chiasm causing visual field defect
• Any medical conditions contraindicated in the Summary of Product Characteristic (SPC) of all drugs

Other protocol-defined inclusion/exclusion criteria may apply
