A Pilot Study of Pre- and Post-operative Use of Somatuline Depot.

September 2, 2021 updated by: Saint John's Cancer Institute

A Pilot Study of Pre- and Post-operative Somatuline Depot Therapy in Acromegalic Patients Treated by Endonasal Endoscopic Surgery: Impact on Early Remission Rates and Perioperative Morbidity

If someone is diagnosed with a pituitary tumor that causes acromegaly (too much growth hormone) the treatment is to have it surgically removed. This study has two phases.

The first phase provides medical treatment with a drug that will be provided for 3 months before surgery to see if complications of surgery are reduced and to see whether or not remission improves following surgery if you have this medical treatment. The drug administered is approved by the FDA for long-term treatment of acromegaly. It is not routinely administered before surgery, and is therefore experimental as used in this way. All other procedures performed during this research are standard of care with the exception of the 3 questionnaires to be completed at each visit.

The second phase of this study is from 3 months until 12 months after surgery and is only for people who do not go into remission after the operation. This phase assesses the possible remission of acromegaly after resuming the drug treatment for an additional 3 to 9 months. The drug will be prescribed by your physician as part of your regular medical care and will not be included as part of the study. All other procedures performed during this research are standard of care with the exception of the 3 questionnaires to be completed at each visit.

The study lasts approximately 16 months - 3 month before surgery and 12 months after surgery.

3 month post-op
Change in Hypertension
Time Frame: 3 months
Change in hypertension after 12 weeks of Somatuline therapy and 3 months after endonasal endoscopic adenoma removal
3 months
Change in Respiratory Function
Time Frame: 12 weeks and 3 months
Change in respiratory function after 12 weeks of Somatuline therapy and 3 months after endonasal endoscopic adenoma removal
12 weeks and 3 months
Change in Quality of Life
Time Frame: 3 months
Change in Quality of Life after 12 weeks of Somatuline therapy and 3 months after endonasal endoscopic adenoma removal
3 months

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Remission Status 1 Year After Surgery
Time Frame: 12 months post-op
