Type 1 diabetes, HbA1c < 7.8%, who have had prior instruction in a complex insulin program, and presently using a MDI insulin program with basal insulin preparations of Glargine or Ultralente and Humalog as the short acting insulin, should be free of hepatorenal abnormalities and hypoglycemia unawareness; non-pregnant, and should be able to perform frequent self monitoring of blood glucose (SMBG) and accept the use of continuous glucose monitoring system (CGMS). They should also possess the skill and understanding of insulin dose adjustments and supplementation.

About this study
Official title: Randomized Trial Comparing Insulin Glargine to Ultra-Lente Insulin in Type I Diabetes
Patients with type 1 diabetes trained in multiple daily insulin injection were treated with two diffferent kinds of long acting insulin preparations. The two insulin preparations were glargine and ultralente insulin. Patients were randomized to receive one of the two insulin preparations for the first 4 months followed by the second preparation for a further four months. Short acting insulin used was the same during both periods. We found that glargine insulin was better than ultralente insulin in our study.
Read the detailed description
Multiple daily insulin injection (MDI) programs are commonly accompanied by considerable glycemic variation and hypoglycemia. In order to determine whether use of insulin glargine as a basal insulin would result in comparable HbA1c with less glycemic variation and hypoglycemia than ultralente insulin, 22 individuals with type 1 diabetes, experienced with MDI, and a HbA1c of <7.8 % were randomized, to receive either glargine or ultralente as the basal insulin for 4-months. Aspart insulin was used as the prandial. Physicians providing insulin dose adjustment advice were masked to the type of basal insulin. Treatment with glargine resulted in lower mean HbA1c, less nocturnal variability , and less hypoglycemia primarily due to less daytime hypoglycemia (p=0.002). On the other hand, serious hypoglycemia and average glucose concentration measured with continuous glucose monitoring system (CGMS) did not differ. We conclude that, while use of either ultralente or glargine as a basal insulin can result in excellent glycemic control, treatment with glargine is associated with slightly but significantly lower HbA1C, with less nocturnal glycemic variability and less hypoglycemia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Patients were randomized to receive one of the two insulin preparations for the first 4 months followed by the second preparation for a further four months.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Basal insulin in people with Type 1 Diabetes, run by Mayo Clinic 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?
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 May 2011. 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?
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?
HbA1c. 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 NCT00276393, 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 23 May 2011.
