Early Intermittent Intensive Insulin Therapy as an Effective Treatment of Type 2 Diabetes (RESET-IT Pilot Study)
A Phase 3 study testing Intermittent insulin therapy and Continuous metformin in people with Type 2 Diabetes, run by Mount Sinai Hospital, Canada at 1 site in Canada.
Trial summary
Type 2 diabetes mellitus is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body).

About this study
Official title: A Randomized Controlled Trial to Evaluate Early Intermittent Intensive Insulin Therapy as an Effective Treatment of Type 2 Diabetes: REmission Studies Evaluating Type 2 DM - Intermittent Insulin Therapy (RESET-IT Pilot Study)
Type 2 diabetes mellitus is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body). The investigators propose a pilot randomized controlled trial to determine whether intermittent intensive insulin therapy is an effective therapeutic strategy that can preserve pancreatic beta-cell function and maintain glycemic control early in the course of type 2 diabetes.
Read the detailed description
In this study, eligible patients with type 2 diabetes will be randomized to either intermittent insulin therapy or continuous metformin therapy, after both arms have first undergone a short course of intensive insulin therapy. The hypothesis under study is whether intermittent insulin therapy can better preserve beta-cell function.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intermittent insulin therapyDrug
Also called Basal insulin glargine and pre-meal insulin lispro
Continuous metforminDrug
Also called Metformin
| Study group | Role | What they receive |
|---|---|---|
| Continuous metformin | Active comparator | After a 3-week course of intensive insulin therapy, participants will be treated with ongoing metformin monotherapy. Metformin will be initiated at 500mg twice a day for the first 2 weeks, before progressing to 1000mg twice a day for the duration of the trial (24 months). Receives: Drug: Continuous metformin |
| Intermittent insulin therapy | Experimental | After a 3-week course of intensive insulin therapy, participants will receive intermittent intensive insulin therapy for 2 weeks every 3 months. The 2-week course of insulin therapy will be repeated at 3-, 6-, 9-, 12-, 15-,18- and 21-months, with final outcome measurement performed at 24-months Receives: Drug: Intermittent insulin therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Baseline-adjusted beta-cell function at 2 years, measured by Insulin Secretion-Sensitivity Index-2 (ISSI-2).
ISSI-2 is an established measure of beta-cell function. ISSI-2 is defined as the product of (i) insulin secretion measured by the ratio of the area-under-the-insulin-curve to the area-under-the-glucose curve and (ii) insulin sensitivity measured by the Matsuda index.
Measured: 2 years
Secondary outcomes (1)
Baseline-adjusted glycemic control at 2-years.
The secondary outcome of baseline-adjusted glycemic control at 2-years will be assessed by A1c (glycated hemoglobin)
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Intermittent insulin therapy and Continuous metformin in people with Type 2 Diabetes, run by Mount Sinai Hospital, Canada at 1 site in Canada.
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 12 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 16 Aug 2018. 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 Canada. 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?
Baseline-adjusted beta-cell function at 2 years, measured by Insulin Secretion-Sensitivity Index-2 (ISSI-2). (time frame: 2 years). 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 NCT01755468, 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 16 Aug 2018; AzTrials last refreshed its copy on 7 Nov 2026.
