Acromegaly is characterized by chronic hypersecretion of growth hormone (GH), clinical features comprise structural and functional changes occurring in practically all organs. Cardiovascular disease is the main reason for morbidity and increased mortality. MedDRA version: 9.1 Level: LLT Classification code 10000599 Term: Acromegaly

Inclusion criteria
Inclusion criteria: 1. Male or female patients of at least 18 years of age 2. Patients with active acromegaly demonstrated by • a lack of suppression of GH nadir to 5 µg/L • elevated circulating IGF-1 concentration (age and sex adjusted) 3. a) Patients who have undergone one or more pituitary surgeries but have not been treated medically or b) de-novo patients who present with a visible pituitary adenoma on MRI and who refuse pituitary surgery or for whom pituitary surgery is contraindicated 4. Patients with a known history or new diagnisis of impaired fasting glucose or diabetes mellitus may be included, however blood glucose and antidiabetic treatment must be monitored closely throughout the trial and adjusted as necessary (see Section 6.6.3) 5.

Exclusion criteria
Exclusion criteria: 1. Patients who are being or were treated with octreotide, lanreotide or dopamine agonists or GH antagonists with the exception of a single dose of short-acting ocreotide or short-acting dopamine agonists. In case of a single dose of short-acting ocreotide, the dose should not be used to predict the response to the ocreotide treatment. The single dose of short acting ocreotide or short-acting dopamine agonists should not be administered in the 3 days prior to randomization. 2. De-novo patients having a visible adenoma on MRI 3. Patients who have received pasireotide prior to randomization 4. Patients with compression of the optic chiasm causing any visual field defect 5. Patients who require a surgical intervention for relief of any sign or symptom associated with tumor compression for whom surgical intervention is indicated 6.

| Main Objective: The primary objective is to compare the proportion of patients with a reduction of mean GH level to < 2.5µg/L and the normalization of IGF-1 to within normal limits (age and sex related) between the two treatment groups at 12 months.;Secondary Objective: assess the effect of pasireotide LAR vs. octreotide LAR on: •reduction of GH to <2.5 µg/L alone at 12 months •proportion of patients with a reduction of mean GH level to < 2.5 µg/L and on the normalization of IGF-1 to within normal limits (age and sex related) at months 6 and 9 •change from baseline in mean GH at 12 months •time to first achievement of mean GH < 2.5 µg/L and on normalization of IGF-1 to within normal limits (age and sex related) •symptoms of acromegaly, specifically: ring size, headache, fatigue, perspiration, paresthesias, osteoarthralgia at 12 months •health related quality of Life at 12 months •PRL levels at 12 months •duration of response for patients achieving reduction of mean GH level to<2.5µg/L and normalization of IGF-1 to within normal limits (age and sex related) at month 12 Compare the overall safety and tolerability of pasireotide LAR vs. octreotide LAR at 12 months Assess pasireotide and octreotide plasma exposure (trough concentrations) ;Primary end point(s): 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) at the end of the 12-month period. | — |
