About this study

The primary objective of this study is to determine the optimal dose of glargine insulin when converting from intravenous short-acting continuous insulin infusions in surgical and intensive care unit patients using a prospective, controlled, parallel group, randomized study design.

Note: Lantus insulin is the proprietary name for glargine insulin.

Read the detailed description

Critical illness causes an impairment of insulin secretion and insulin action, resulting in hyperglycemia even in normal individuals and a worsening of the hyperglycemia in patients with diabetes. Normalization of elevated glucose levels by intensive insulin infusion therapy in these critically ill patients has been proven to dramatically improve in-hospital mortality rates. After glucose levels have been controlled with insulin infusions, the best way to convert them to subcutaneous insulin regimens has not been demonstrated conclusively but the insulin regimen best suited is a combination of a basal insulin such as glargine (Lantus) insulin with premeal insulin boluses using a short-acting insulin such as Lispro or Aspart.

Subjects will be randomized into three groups, 25 subjects in each group, the groups differing according to the starting dose of glargine insulin as follows:

  1. Multiply the total daily IV insulin dose, using the final 6 hour infusion rate to estimate the total daily dose, by 0.4 to get the starting dose of glargine, continuing the insulin drip for 5 hours after giving the glargine before stopping the infusion;
  2. Multiply the total daily IV insulin dose, using the final 6 hour infusion rate to estimate the total daily dose, by 0.6 to get the starting dose of glargine, continuing the insulin drip for 5 hours after giving the glargine before stopping the infusion;
  3. Multiply the total daily IV insulin dose, using the final 6 hour infusion rate to estimate the total daily dose, by 0.8 to get the starting dose of glargine, continuing the insulin drip for 5 hours after giving the glargine before stopping the infusion.

The glargine insulin will then be continued as the basal insulin, adjusting doses every 24 hours based on the fasting blood glucose level. In addition, patients will receive Lispro or Aspart insulin as prandial bolus insulins with the goals premeal being 80 - 120 mg/dl, including bedtime. Glucose measurements will be obtained every 1- 4 hours while patients are on their insulin infusions, depending upon the stability of their condition and the stability of their glucose levels. Following transfer to glargine insulin, they will have glucose measured at least four times per day, premeal and bedtime as per standard protocol in the hospital for patients receiving insulin. Glucose data will be obtained from such patients and this will be compared among the various glargine regimens.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing insulin glargine in people with Hyperglycemia and Diabetes, run by Northwestern University at 1 site in United States.

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 2 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 6 Apr 2009. 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 United States. 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 6 Apr 2009). 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?

Percentage of Blood Glucose Values Between 80 - 140 (time frame: First 24 hours after conversion). 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 NCT00338104, which also lists 1 linked publication.

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 6 Apr 2009.
