About this study
Investigators with the goal of optimizing glycemic and blood pressure control saw type 1 diabetic patients weekly. A control group received 3-4 subcutaneous insulin injections per day; an intravenous insulin pulsed infusion group received, in addition, three one hour infusions in a pulsatile fashion over one eight hour period each week. Patients were followed for 12 months with periodic testing of renal function by repeated blood and urinary analyses; diabetes control by blood testing and diabetes impact measurement score; cardiac and autonomic function by echocardiography, 24 hour electrocardiographic testing; and visual changes with repeated fundus photography. The study hypothesis was that correction of respiratory quotient would correct the defect leading to microvascular complications of diabetes (Type 1).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Investigators with the goal of optimizing glycemic and blood pressure control saw type 1 diabetic patients weekly. A control group received 3-4 subcutaneous insulin injections per day; an intravenous insulin pulsed infusion group received, in addition, three one hour infusions in a pulsatile fashion over one eight hour period each week. Patients were followed for 12 months with periodic testing of renal function by repeated blood and urinary analyses; diabetes control by blood testing and diabetes impact measurement score; cardiac and autonomic function by echocardiography, 24 hour electrocardiographic testing; and visual changes with repeated fundus photography. The study hypothesis was that correction of respiratory quotient would correct the defect leading to microvascular complications of diabetes (Type 1).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing CIIIT in people with Diabetic Nephropathy and Diabetic Retinopathy, run by Joslin Diabetes Center 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 1 inclusion and 1 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 15 Jan 2008. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
Rate of loss of creatinine clearance (time frame: 18 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 NCT00594152, which also lists 2 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 15 Jan 2008; AzTrials last refreshed its copy on 8 Nov 2026.
