About this study

Official title: Control-IQ Technology in Individuals With Type 2 Diabetes (2IQ)

A prospective, multicenter study of 6 weeks of home use of Control-IQ technology in individuals with type 2 diabetes age 18 and older.

Read the detailed description

The objective of this prospective, multicenter study is to assess safety and explore glycemic outcomes associated with use of Control-IQ technology in adults with type 2 diabetes who require insulin. After an initial run-in period, all participants will use the study system (pump and CGM) for 6 weeks. Participants will perform exercise challenges once each week during the study.

Being tested
Control-IQ technology 1.5
Keywords
type 2 diabetes, Control-IQ technology, automated insulin dosing, automated insulin delivery

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Control-IQ technology 1.5Device

    All subjects wearing the t-slim X2 insulin pump with Control-IQ technology 1.5, and wearing the Dexcom G6 sensor.

    Outcomes will be analyzed overall and subgroup analysis will be performed by Group, and by baseline A1c level.

Questions about this trial

What is this clinical trial studying?

A study of Type 2 Diabetes Treated With Insulin, run by Tandem Diabetes Care, Inc. at 3 sites 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 12 inclusion and 15 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 6 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Mar 2024). 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?

CGM Time Below 54 mg/dL (time frame: 14 weeks). The study lists 2 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 NCT05111301, 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 6 Mar 2024.
