About this study
Official title: The Utility of Insulin Glargine (Lantus) Compared to NPH in Ethnic Minority Type 2 Diabetic Subjects on Combination Insulin-Oral Agent Therapy
To compare the efficacy and safety of once-nightly insulin glargine versus twice-daily NPH insulin in ethnic minority type 2 diabetic patients inadequately treated with once-nightly NPH insulin alone.
Read the detailed description
Insulin glargine has a longer action than compared to NPH insulin, but whether this results in improved control when compared to twice-daily NPH insulin is not known when used in low-income ethnic minority patients. This study investigates whether insulin glargine may be more or less effective and safe than twice-daily NPH insulin in this population.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Insulin glargine at bedtime instead of NPH and NPH twice-daily in people with Type 2 Diabetes Mellitus, run by Charles Drew University of Medicine and Science 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 7 inclusion and 10 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: stopped early, as of the sponsor's last update on 2 Nov 2023. 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 7 Oct 2010). 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?
Hemoglobin A1c Change From Baseline (time frame: Baseline to 6 months). 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 NCT00687453, 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 2 Nov 2023.
