Brief Summary:
Approximately half of patients with acromegaly do not respond to treatment with somatostatin receptor ligands such as octreotide LAR. This may be due to inadequate drug delivery if the standard of care regular injection is inaccurately delivered in the intramuscular (IM) compartment. Ultrasound guidance of IM injections may improve accuracy of placement of IM injections and increase drug levels, thereby improving efficacy of octreotide LAR for the treatment of acromegaly. The purpose of this study is to determine whether octreotide LAR drug levels differ if given by ultrasound-guided IM injection or by regular IM injection in patients with acromegaly.

Arm Intervention/treatment
Experimental: Ultrasound-guided IM injections of octreotide LAR
Subjects received octreotide LAR 30 mg injection via ultrasound-guided IM gluteal injection every 28 days for 3 months.
Drug: Octreotide LAR 30 MG Injection
Stable dose of 30 mg octreotide LAR, or a dose determined by historical dosing, delivered every 28 days for 3 months.
Other Name: Sandostatin LAR

Active Comparator: Regular IM injections of octreotide LAR
Subjects received octreotide LAR 30 mg injection via regular IM gluteal injections every 28 days for 3 months

Primary Outcome Measures :
  1. Plasma Octreotide Level After Each Treatment Phase [ Time Frame: 3 months ]
    Venous sampling was performed at each visit immediately prior to each IM injection. Levels were measured at each visit and mean for the group was calculated after each treatment phase.


Secondary Outcome Measures :
  1. Serum IGF-1 Level [ Time Frame: 3 months ]
    Venous sampling was performed at each visit immediately prior to each IM injection. Levels were measured at each visit and mean for the group was calculated after each treatment phase.
