3. Females must be non-pregnant and non-lactating, and either surgically sterile, post-menopausal, or using effective method(s) of birth control
4. Willing to provide signed informed consent

Exclusion Criteria

1. Treatment naïve or treatment-withdrawn acromegaly subjects

9. Cardiovascular conditions or medications associated with prolonged QT or those which predispose subjects to heart rhythm abnormalities
10. Subjects with symptomatic cholelithiasis
11. Subjects with clinically significant abnormal findings during the Screening Period, or any other medical condition(s) or laboratory findings that, in the opinion of the Investigator, might jeopardize the subject's safety or ability to complete the study
12. Subjects currently taking pasireotide LAR (within 24 weeks prior to Screening) or pegvisomant, dopamine agonists (within 12 weeks prior to Screening), or short acting somatostatin analogs (within 12 weeks prior to first dose of study drug)
