Brief Title
Ultrasound Guided Octreotide LAR Injection in Acromegaly
Official Title
Study to Determine Whether Ultrasound Guidance Improves Delivery and Efficacy of Intramuscular Injection of Long-Acting Octreotide in the Treatment of Acromegaly
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.
