Study summary

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.

Eligibility criteria

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.

The record gives a start of Jul 2002, a primary completion of Dec 2003 and a completion of Dec 2003. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 23, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
