Octreotide Efficacy and Safety in First-line Acromegalic Patients

Study Overview
=================
Brief Summary
-----------------
Primary Acromegaly is a clinical and metabolic disease caused by growth hormone (GH) hypersecretion from a pituitary adenoma and is an insidious, chronic disease that is associated with bony and soft tissue overgrowth. Goals of therapy are to eradicate the tumor, suppress GH secretion, normalize IGF-I levels, and preserve normal pituitary function. This study will evaluate the safety and efficacy of octreotide as primary therapy for the treatment of acromegaly and as therapy for patients with acromegaly and a pituitary macroadenoma or microadenoma.

Presence of a pituitary tumor (microadenoma or macroadenoma), documented by a MNR performed in the 12 weeks before enrolment. Absence of nadir suppression of the nadir of GH to < 1.0 ng/mL, after oral administration of 75 g of glucose (OTTG). IGF-I levels over normal upper limits, e.g. 97 percentile (age- and sex-matched). Tolerance shown with a test of a subcutaneous injection of octreotide Written Informed Consent before any procedure specific to the study. Inclus Exclusion Criteria: Previously treated patients with any therapy for acromegaly, including surgery, radiotherapy, bromocriptin, and somatostatin analogues. Compression of optic chiasm that produces any impairment of field of vision. Need of surgery to improve any neurological sign or symptom associated with a direct incidence on the tumour. Intolerance to octreotide or to any component of Sandostatin® LAR® preparation. Patients with an hepatic condition such as cirrhosis, active or persisting chronic hepatitis, or other hepatopathy of fast evolution. Pregnant women History of alcohol or drug abuse in the six months prior to the inclusion visit. Patients suffering from any condition that may jeopardize the interpretation of study results or may impede to obtain informed consent Intake of an investigational drug during the study and 30 days before patient inclusion in this study Other protocol-defined inclusion / exclusion criteria may apply.
