What is being measured

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

  1. Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 30 Minutes (Mins) Pre-Breakfast

    The PWV measured arterial stiffness in the aortic and brachial arteries of T2DM participants. The Least Square (LS) mean was estimated from a mixed-effect analysis of covariance (ANCOVA) model that was adjusted for age, body mass index (BMI), visit, group, condition, group by condition, and random participant.

    Measured: 30 mins (pre-breakfast)

  2. Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 60 Minutes (Mins) Post-Breakfast

    The PWV measured arterial stiffness in the aortic and brachial arteries of T2DM participants. The Least Square (LS) mean was estimated from a mixed-effect analysis of covariance (ANCOVA) model that was adjusted for age, body mass index (BMI), visit, group, condition, group by condition, and random participant.

    Measured: 60 mins (post-breakfast)

  3. Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 120 Minutes (Mins) Post-Breakfast

    The PWV measured arterial stiffness in the aortic and brachial arteries of T2DM participants. The Least Square (LS) mean was estimated from a mixed-effect analysis of covariance (ANCOVA) model that was adjusted for age, body mass index (BMI), visit, group, condition, group by condition, and random participant.

    Measured: 120 mins (post-breakfast)

  4. Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 180 Minutes (Mins) Post-Breakfast

    The PWV measured arterial stiffness in the aortic and brachial arteries of T2DM participants. The Least Square (LS) mean was estimated from a mixed-effect analysis of covariance (ANCOVA) model that was adjusted for age, body mass index (BMI), visit, group, condition, group by condition, and random participant.

    Measured: 180 mins (post-breakfast)

  5. Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 240 Minutes (Mins) Post-Breakfast

    The PWV measured arterial stiffness in the aortic and brachial arteries of T2DM participants. The Least Square (LS) mean was estimated from a mixed-effect analysis of covariance (ANCOVA) model that was adjusted for age, body mass index (BMI), visit, group, condition, group by condition, and random participant.

    Measured: 240 mins (post-breakfast)

Secondary outcomes (5)
  1. Change in Pulse Wave Amplitude (PWA)

    The PWA measured systemic arterial stiffness (augmentation index). PWA was reported as a percentage of systolic peak and calculated as the difference between second and first systolic peak in an ascending aortic pulse pressure waveform divided by the first systolic peak then multiplied by 100. The change in PWA from baseline [30-minute (min) pre-breakfast] is reported.

    Measured: 30 mins (pre-breakfast), 60, 120, 180 and 240 mins (post-breakfast)

  2. Change in Peripheral Artery Tonometry (PAT)

    The PAT device is a pneumatic plethysmograph that applies uniform pressure to the surface of each finger tip and measures digital pulse amplitude. The PAT was reported as a percentage of pulse amplitude and expressed as the ratio of post deflation to baseline pulse amplitude in hyperemic finger divided by the same ratio in the contralateral finger that served as a control. The change in PAT from baseline [30-minute (min) pre-breakfast] is reported.

    Measured: 30 mins (pre-breakfast), 120 and 240 mins (post-breakfast)

  3. Change in QT Interval on Electrocardiogram (ECG)

    QT interval is a measure of time from the beginning of the QRS complex to the end of the T wave on an ECG during which contraction of the ventricles occurs. Changes in QT interval from baseline [30-minute (min) pre-breakfast] are reported.

    Measured: 30 mins (pre-breakfast), 60, 120, 180 and 240 mins (post-breakfast)

  4. Change in Blood Glucose (BG)

    Changes in BG from the baseline [30-minute (min) pre-breakfast] are reported.

    Measured: 30 mins (pre-breakfast), 50, 110 ,170, and 230 mins (post-breakfast)

  5. Change in Postprandial Pulse Wave Velocity (PWV)

    The PWV measured arterial stiffness in the aortic and brachial arteries of healthy participants and T2DM participants. Changes in PWV from baseline [30-minute (min) pre-breakfast] are reported.

    Measured: 30 mins (pre-breakfast), 60, 120, 180 and 240 mins (post-breakfast)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lispro in people with Diabetes Mellitus, Type 2, run by Eli Lilly and Company at 1 site in Finland.

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 6 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 3 Apr 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 Finland. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Apr 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Postprandial Pulse Wave Velocity (PWV) in Type 2 Diabetes Mellitus (T2DM) Participants at 30 Minutes (Mins) Pre-Breakfast (time frame: 30 mins (pre-breakfast)). The study lists 5 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 NCT01159938, which also lists 3 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 3 Apr 2014.
