What participants receive

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

  • Isoglycemic ClampDrug

    Isoglycemic Clamp, a procedure that includes IV infusion of short-acting Insulin (Part I) and glucose (Part I and 2)

  • Comparator: insulin glargineDrug

    Also called LANTUS

    Insulin glargine at 0.4 U/kg

Part 2Active comparatorPart II of the trial
Receives: Drug: Isoglycemic Clamp; Drug: Comparator: insulin glargine

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part I: The within-subject standard deviation in duration of action of glargine (the difference between onset of action and end of action)

    Measured: Baseline and 30 hours

  2. Part II: The within-subject coefficient of variation in time-action profile of glargine for AUC-GIR (AUC of glucose infusion rate), GIRmax (maximum level of glucose infusion rate), over the duration of action of glargine

    Measured: Baseline and 30 hours

Secondary outcomes (2)
  1. Part I: The within-subject coefficient of variation in time-action profile of glargine for AUC-GIR and GIRmax over the duration of action of glargine

    Measured: Baseline and 30 hours

  2. Part II: The within-subject standard deviation in duration of action of glargine (the difference between onset of action and end of action)

    Measured: Baseline and 30 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Isoglycemic Clamp and Comparator: insulin glargine in people with Diabetes, run by Merck Sharp & Dohme LLC.

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 10 inclusion and 13 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 23 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Part I: The within-subject standard deviation in duration of action of glargine (the difference between onset of action and end of action) (time frame: Baseline and 30 hours). 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?
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 23 Jul 2015.
