About this study

In normal physiology, glucagon from pancreatic alpha cells plays an important role in maintaining glucose homeostasis via its regulatory effect on hepatic glucose production. Patients with type 2 diabetes exhibit elevated plasma glucagon levels in the fasting state, and in response to ingestion of glucose or a mixed meal.glucagon, glucagon concentrations fail to decrease appropriately and may even increase. This diabetic hyperglucagonaemia may therefore contribute importantly to the hyperglycaemia of the patients.

Several glucose-lowering treatment modalities have been shown to affect glucagon levels in patients with type 2 diabetes, but the role of glucagon in the glucose-lowering effects of these treatment modalities has been difficult to discern. By using a glucagon receptor antagonist (GRA) the investigators will exploit glucagon receptor antagonism to delineate the role of glucagon during treatment with sodium-glucose co-transporter 2 (SGLT2) inhibitors and dipeptidyl peptidase 4 (DPP-4) inhibitors, which have been shown to increase and decrease plasma glucagon levels, respectively.

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?

Difference in postprandial glucose excursions (linagliptin) (time frame: Area under the curve (AUC) time frame: 0, 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 105, 120, 150, 180, 210, 240 minutes. Comparison between experimental days with linagliptin (A1, A2, A3, A4)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02792400, which also lists 2 linked publications.

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 8 Apr 2020.
