Co-treatment With Pegvisomant and a Somatostatin Analogue (SA) in SA-responsive Acromegalic Patients
A study testing Pegvisomant and Somatostatin analog (lanreotide or octreotide) in people with Acromegaly and Insulin Resistance, run by University of Aarhus at 1 site in Denmark.
Trial summary
The purpose of this study is to investigate if co-treatment of acromegalic patients, who beforehand are considered well-controlled on SA monotherapy, with pegvisomant and SA will improve insulin sensitivity and glucose tolerance, and if these effects of co-treatment can be obtained at a neutral cost as compared to SA… Read more about this study

About this study
Official title: Co-treatment With Pegvisomant and a Somatostatin Analogue (SA) in SA-responsive Acromegalic Patients: Impact on Insulin Sensitivity, Glucose Tolerance, and Pharmacoeconomics

- Acromegaly, Insulin Resistance, Impaired Glucose Tolerance
- Being tested
- Pegvisomant, Somatostatin analog (lanreotide or octreotide)
- Keywords

Questions about this trial
What is this clinical trial studying?
A study testing Pegvisomant and Somatostatin analog (lanreotide or octreotide) in people with Acromegaly and Insulin Resistance, run by University of Aarhus at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Insulin sensitivity (time frame: 0 and after 24 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2012; AzTrials last refreshed its copy on 8 Nov 2026.
