What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • first phase insulin secretion (FPIR), Hyperinsulinemic euglycemic clamp (HEC), glucose tracer, and palmitate tracerOther

    FPIR: intravenous infusion of 20 % glucose 0.3 mg/kg in 2 minutes followed by blood sampling at times 0, 2, 4, 6, 8, and 10. Duration 10 minutes.

    HEC: intravenous infusion of actrapid 1mU/kg/minute, simultaneous infusion of 20 % glucose at variable rate to reach plasma blood glucose level of 5 mmol/L. Duration 120 minutes

    Glucose tracer: bolus of 3H3glucose (12µCi) followed by infusion of 3H3glucose (0,12 µCi/min). Duration 120 minutes.

    Palmitate tracer:[9,10-3H]-palmitate 0,3 µCi/min. Duration 60 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing first phase insulin secretion (FPIR), Hyperinsulinemic euglycemic clamp (HEC), glucose tracer, and palmitate tracer in people with Hyperlipidemia and Diabetes Mellitus, 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 2 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 2 Dec 2014. 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 secretion (time frame: 10 minutes). 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 NCT01571609, 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 2 Dec 2014.
