Primary Outcome Measures :
  1. Proportion of subjects who meet responder criteria (based on the mean of two consecutive insulin-like growth factor-1 [IGF-1] measurements ≤ upper limit of normal [ULN]) [ Time Frame: 13 Weeks ]

Secondary Outcome Measures :
  1. Proportion of subjects who achieve serum growth hormone (GH) <5.0 ng/mL [ Time Frame: 13 Weeks ]
  2. Change in IGF-1 levels [ Time Frame: From Week 10 to Week 13 ]
  3. Change in GH levels [ Time Frame: From Week 8 to Week 13 ]
  4. Change in symptoms of acromegaly [ Time Frame: From Week 10 to Week 13 ]
    Global assessment of symptoms of acromegaly (headache, excessive sweating, extremity swelling, joint pain, sleep apnea, fatigue, and paresthesia; each assessed consistent with adverse event criteria [mild, moderate, severe])
